INTRODUCTION
In terms of Section 10(7) (b) of the Division of Revenue Act No 10 of 2014 (DORA) as
promulgated in Government Gazette No 37595 dated 26 April 2014, the transferring
national officer must submit a quarterly performance report for all Programmes funded by
a Schedule 6 allocation within 45 days after the end of each quarter, in accordance of the
relevant framework to the National Treasury.
The Regional Bulk Infrastructure Grant (RBIG) is a Schedule 6 indirect conditional grant
for the benefit in kind of municipalities.
The objective of this report is to provide a bi-annual performance evaluation report
covering the first and second quarters of RBIG funded projects, in compliance with the
DoRA. The objective of this evaluation was to determine whether the progress on the
project is commensurate with the expenditure to date as well as to determine whether the
project is still on course in terms of the original planning.
This performance evaluation report, covering the first 6 months of the 2014/15 fiscal year,
is for KSD Presidential Intervention Project (PIP) - Mthatha Bulk Water Supply Project is
being implemented under the strategic objectives of the Mthatha Regional Bulk Water
Supply Scheme. It is one of the Regional Bulk Infrastructure Grant projects currently being
implemented by the OR Tambo District Municipality in the Eastern Cape Province, with
Department of Water and Sanitation (DWS) as funder. OR Tambo DM in October 2012
finalised the appointment of Amatola Water Board as an Implementing Agent for this
project.

BACKGROUND
2.1
Description of Project
The primary focus is to augment current bulk water supply within the Mthatha Town and
KSD Municipality, located in the OR Tambo District Municipality in the Eastern Cape. The
project aims to increase the capacity of the water treatment works and to improve the bulk
water distribution to the region thereby unlocking housing and commercial developments.
The project aims at initially focusing on five corridors within a radius of 30 km from
Mthatha. These corridors are Mthatha, Libode, Mqanduli, Ngqeleni and Nqadu
Corridors.
The targeted Local Municipality is KSD and its neighbouring Nyandeni Municipality. The
area is predominantly rural in nature, with numerous villages scattered throughout the
region. Mthatha is the largest town, with municipal offices, hospital, university a
magistrate’s court, police station, prison, and a number of businesses and light industries.
The area has been, and still is, characterised by significant backlogs in water and
sanitation, as evidenced by the results of the Community Survey, Statistics South Africa,
in 2007.
2.2
Project History
The Mthatha Presidential Intervention Projects together with their catalyst projects have
been earmarked for infrastructure development and socio economic development in the
OR Tambo District. These projects include some of the projects currently being
4
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
implemented by GIBB as the Lead Consultants and some SMME’s targeted for skills
transfer and empowerment.
Some of the projects involve implementation of the infrastructure rehabilitation that have
been identified thus far and also for the infrastructure upgrade required in order to
accommodate housing developments such as the Breaking New Ground (BNG) (17,000
Units) proposed developments; and also for refurbishment of the Mthatha Water Supply
as part of the Presidential intervention. Should funding be provided for the implementation
phase, this would go a long way to transforming Mthatha into the economic and social
power house of the OR Tambo District Municipality and the whole of Eastern Cape.
It was agreed that the District and KSD Municipality work together to promote the
provision of the primary bulk services for 17,000 new households, the interim focus
being the targeted 6,500 new homes. Should these primary bulk services not be
constructed, no new development can take place in the area.
Based on studies undertaken by GIBB the capacity of Thornhill Water Treatment Works
(WTW) will need to be increased by 20 Mℓ/D to cater for the proposed new BNG
(approximate 6,500 units) housing project. The Thornhill WTW is currently operating at full
capacity (60 Mℓ/D). The Thornhill raw water mains and raw water pump station will also
require upgrade to cater for the additional 20 Mℓ/D. It is proposed by the OR Tambo DM
that a new Water Treatment Works at Rosedale of 25 Mℓ/D would be required as the initial
unit that would eventually be upgraded to 150 Mℓ/D.
GIBB had prepared a technical report that was sent to MIG for funding application. The
report contained most of the bulk work that would be required to be done in order to
accommodate the development of 17,000 new houses. This appointment was for the
planning, design, and construction monitoring of the bulk water supply components of the
scheme, to be undertaken in a phased manner over a number of years, based on BNG
Developments within the area and the availability of funding. The estimated cost of the
bulk water supply scheme is approximately R600 million. Funding is being made
available by DWS. In addition to the targeted BNG Developments, OR Tambo DM
through Amatola and GIBB have identified four corridors within a radius of 30 km from
Mthatha and these will be targeted for Bulk Water Infrastructure for the period of 5 years.
The overall cost estimates for this scope of work is approximately R2.5 billion.

Mthatha Dam as Water Source:
Mthatha Dam is the primary source of water. Mthatha Dam supplies water to the Thornhill
WTW. The dam is located approximately 6 km north-west of the town. The dam was
constructed in 1977 for the purpose of water supply to Mthatha Municipality and storage
for the releases to Eskom hydropower stations. The Mthatha dam is a rock-fill type and
has an ogee-crescent shaped concrete spillway. The catchment area for the dam is
6
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
approximately 886 km2. The mean annual runoff (MAR) for the dam is 212 million m 2. The
approximate co-ordinates are:
31º 32´ 24˝ S
28º 44´ 13˝ E
The dam has a 1-in-50 year yield of 145,5 million m3 per annum of which 21.9 million m3
per annum (60 Mℓ/D AADD – annual average daily demand) is allocated to Thornhill Bulk
Water Supply for domestic, commercial and industrial usage.
There is an additional 15.3 (41.9 Mℓ/D AADD) million m3 per annum to be allocated to the
proposed Rosedale Water Supply Scheme (a supplementary for the peri-urban villages).
The proposed additional supply to Thornhill Bulk of approximately 9.1 million m 3 per
annum (20 Mℓ/D ) can still be supplied adequately by the Mthatha dam.
Additional supply from the Mthatha Dam will also be extracted through the proposed
Rosedale Regional Treatment Works.

Project Concept, Design and Plan
The projected daily demands, current and future water audit are all indicative that the
Thornhill Water Supply system needs an urgent upgrade. The current bulk water
distribution system and the relevant zone system reflect imbalances in terms of
addressing demand and storage needs and therefore require major alterations. Other
supportive factors leading to the proposed project are as follows:







Shortage of current and future storage capacity
Old infrastructure (90% AC pipes over 25 years old)
Long pump durations (Average 20 hrs)
Lack of Town Planning and Water Supply Coordination
Imbalance of flow pressures
Inadequate revenue collection
Poor Operation and Maintenance.
The design philosophy below is based on the integrated approach in order to address the
key problems associated with the Thornhill Water Supply system.
The purpose of the project is to ultimately supply 150 Mℓ/day of potable water to a
population of 1,000,000 people (approximately 200,000 households), allowing for an
increase in the average consumption per capita from 90 ℓ/c/d to 150 ℓ/c/d over a 20-year
time horizon. The Medium Term targets are a supply of 115 Mℓ/day of potable water to a
population of 750,000 people (approximately 150,000 households) and the Short Term
target is to supply 95 Mℓ/day to a population of 650,000 people (approximately 130,000
households. The targeted categories of consumers to be supplied with potable water are
domestic water users throughout the KSD Local Municipality and Nyandeni Municipality,
and commercial and light industrial users and institutional users mainly within the towns of
8
REGIONAL BULK INFRASTRUCTURE GRANT

Mthatha, Mqanduli, Ngqeleni and Libode. These beneficiaries and the required bulk
infrastructure have been captured in a master plan report.
In essence, this Master plan covers the following:





Upgrading the delivery of raw water from Mthatha Dam to Thornhill Water Treatment
Works;
Extending the capacity of the Thornhill Waterworks by 20 Mℓ/d to 80 Mℓ/d (current)
and by a further 40 Mℓ/d in the short-to-medium term;
Upgrading the clear water pumping capacity to Mthatha town and Southern and
Eastern surrounds out of Thornhill Waterworks;
Constructing a new 25 Mℓ/d waterworks (Rosedale), upgradable in 25 Mℓ/d modules
to 100 Mℓ/d, to supply the areas to the North and West of Mthatha town;
Constructing a new system of bulk supply rising and gravity mains and reservoirs to
transfer the clear water pumped out of the Thornhill and Rosedale Waterworks to
the extended areas of supply up five (5) corridors:
o

Nqadu Corridor (to the North)
Airport Corridor (to the West)


Upgrade reticulation links to BNG areas in and around Mthatha
Upgrade storage capacity where needed (particularly relevant for the BNG areas).


KD Matanzima Airport
The Military Base near the airport
The Bedford Hospital
The Nelson Mandela Hospital
Construction of the first two items above and the first stages of Libode are already
underway.
The methodology that was adopted in the planning stage of the project was to review the
Mthatha Master Plan and technical reports for water supply by GIBB, and other
professional service providers who had been working in the area, and thereafter to
propose a bulk water supply scheme that complied with the guidelines and principles that
have been used by Water Boards. In the context of Mthatha this involved taking into
account the need for adequate, reliable water source (Mthatha Dam) that is treated in a
two WTW plants (Thornhill and proposed Rosedale), feeding water into a primary and
secondary bulk distribution network that is capable of supplying strategically placed bulk
reservoirs that supply a number of reticulation networks, so as to provide potable water to
a large number of communities. The connections from the bulk treated water supply
system to the villages do not, at this stage, form part of GIBB’s current appointment.
The scheme comprises a number of components, viz. the raw water supply system, the
upgrade of the secondary bulk infrastructure and reservoirs as described below:

REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
Increasing Raw Water Supply System
Raw water is conveyed to the Thornhill Water Treatment Works via a gravity pipeline. An
emergency raw water pump station, with a capacity of 23 Mℓ/D is located on the Mthatha
River, below the dam. Raw water gravitates from the Mthatha Dam into Thornhill Water
Treatment Works via a short section of 1,000 mm diameter pipe through the dam
embankment, and then via two steel pipes, one 600 mm diameter, and the other 800 mm
diameter.
Raw Water Pump Station
The original system was designed using the 600 mm diameter pipeline. With low water
levels and higher water demand, this was insufficient to provide adequate water, and a
raw water booster pump station catered for these system requirements. It is assumed that
this booster pump station delivered water to an existing 20 Mℓ balancing dam via 600 mm
diameter pipes. From this elevation, the flow can gravitate to the Thornhill Water
Treatment Works.
To upgrade the system to provide 88 Mℓ/day, this system would require the pumps to be
modified and refurbished. The pump station would then deliver the flow against a head of
10.497 m at conditions where full flow is delivered with the dam level down at 25% of the
full supply level.
Existing 600 mm AC Pipeline
The 600 NB AC pipeline was installed to supply water from the dam to the water treatment
works under gravity, but was augmented at a later date with the rising steel main to make
use of the lower water levels in the dam to enable water at lower levels to be raised by
means of pumping in order to get an adequate water supply to the water treatment works.
However, at the time of the assessment, it was speculated that the reason for the 600 mm
NB AC line being closed (sometimes) at the water treatment works was to prevent suction
head problems in the common manifold upstream between the dam and the pump station
during pimping. The ‘starvation’ of water to the pump sets could result in pump cavitation,
which will significantly reduce the life expectancy of the pump sets. The 600 mm diameter
asbestos pipeline is currently operated only as a gravity supply, and is capable of
conveying a maximum of 31 Ml/d (375 l/s.) only when the Mthatha Dam is full. When the
Dam level has dropped from full supply of 692.94 MSL to approximately 685.0 MSL, the
gravity flow drops to only 17 Ml/d (200 l/s). Furthermore, the pressure in the pipeline must
be boosted to lift the water over the highest point which has an elevation of 684.5 MSL,
approximately 2 000 m from the Dam. Although the 600 mm NB AC gravity pipeline was
not operational, the line is still under pressure at it has been isolated at the water
treatment works. However, the steel portions of this line, where it crosses the river on the
pipe bridges, have corroded badly and are in need of significant repair, but preferably
replacement.
Existing 800 mm diameter Steel Pipeline
This pipeline has been in service for some time (over 28 years), and is reportedly in need
of some rehabilitation. The 800 mm diameter steel pipeline is currently operated via the
raw water booster pump station. It has been calculated that, when operated under gravity,
a maximum flow of 64 Ml/d (750 l/s) can be achieved only when the Mthatha Dam is full.
When the Dam level has dropped from full supply of 692.94 MSL to approximately 685.0
MSL, the gravity flow drops to only 35 Ml/d (420 l/s). The pressure in this pipeline must
also be boosted to lift the water over the highest point which has an elevation of 684.5
MSL, approximately 2,000 m from the Dam. The status of the operational 800 mm NB
steel rising main is in a poor condition, but not beyond repair, and with an extensive
10
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
maintenance programme the situation could be well improved. There were a number of
leaks along the pipeline, mostly in the vicinity of welds. The poor status of the fittings
associated with these two pipelines warrants special mention as provided below:



Main air valve bolts are corroded with associated leaks and submergence of the
equipment
Some chambers had no access ladders for ease of maintenance, and some
chamber lids necessary for the protection of the equipment were missing.
The external corrosion protection of pipes over pipe bridges has deteriorated and
some rust visible.
As the pipeline(s) increase in size and the friction losses decrease, so the amount of
power decreases. The analyses therefore compare the decrease in running cost with the
increase in capital cost associated with the larger diameter pipes. This analysis is based
on considering the net present value of each option over 20 years, and using a discount
rate of 3%, taking capital, maintenance and running costs into account.
It has been assumed that the full flow should be delivered, even when the level of water in
Mthatha Dam has dropped to 25% of full supply level. It is further assumed that should
the water level drop below 25%, the design flow could be reduced, as a result of water
restrictions, to 80% of the design flow when the dam is 20% full.
The spread of housing to the east of the Thornhill Water Treatment Works, known as
Phola Park has dwellings constructed in the pipeline servitude over both raw water
pipelines, and is a matter for concern, that would need to be urgently addressed.
Pipe Materials
Bulk water supply pipelines of this nature, require that the most durable and reliable
materials have to be used. The experience of all major water supply authorities in South
Africa has indicated that there are two issues – proven durability of the material of the
pipe, and protection of the material from corrosion. The most durable pipe materials that
are considered for this application are steel, ductile iron and GRP. Corrosion protection for
steel and ductile iron will be cement mortar lining internally and possibly externally, but
epoxy and tape systems will also be considered. Cathodic protection may be indicated as
being required during detailed design.
The design has assumed the use of cement mortar lined pipes, with the associated
internal diameters used for the hydraulic calculations.
Emergency Raw Water Pump Station
On the site of the Thornhill water Treatment Works there is a pump station that draws
water directly from the Mthatha River, and delivers to the head of works via the raw water
pipeline from the Mthatha Dam (600 mm diameter). The pipe work from each emergency
pump is 400 mm diameter, with two pumps delivering into a short section of 450 mm
diameter pipe before the connection to the main 600mm diameter supply pipeline.
Assuming a velocity of 1.5 m/s in the 450 mm diameter pipeline, an additional (or
alternative to the Mthatha Dam) flow of 21.6 Mℓ/d (250 ℓ/s) can be abstracted from the
river. In 2004, an additional river abstraction pump and dedicated 400 mm diameter steel
rising main across the water treatment works site was planned. The design of this system
allows for a further flow of 21.6 Mℓ/d (250 ℓ/s) to be abstracted from the river with this
separate system.
11
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
The Emergency Raw Water Pump Station can therefore deliver up to a total of 43.2 Mℓ/d
(500 ℓ/s) in this configuration. It is understood that the pumps are not currently (December
2011) fully operational. During the implementation of this project, the Emergency Raw
Water Pump Station will be reinstated so that it would augment the system especially
during raw water pipe installation and refurbishment.
Figure 3: Existing Emergency Raw Water Pump Station at Thornhill
Raw Water Pipe at Mthatha DAM Intake Tower
The design of the upgrading of the raw water supply pipelines takes into account the short
term high head losses and velocities in the Mthatha dam Intake tower (at 1 100 ℓ/s the
velocity is some 3.3 m/s) until this pipe work is upgraded, with an associated head-loss of
5.6 m before reaching the existing raw water booster pump station. Assuming a drought
condition, with a low water level in Mthatha Dam of 681.0 m (msℓ), the hydraulic grade line
will drop to an absolute minimum of 675.4 m (msℓ) at the raw water pump station where
the ground level is 675 m (msℓ). It is assumed that under such extreme drought
conditions, however, there will be water restrictions in place, and there would not be
routine abstraction at maximum flow rate, even though it will be possible.
With the upgrading of the pipelines from the booster pump station to the Thornhill Water
Treatment Works, it will be possible for the additional head required from the booster
pumps to be reduced to a minimum – indeed, with the levels of water in the Mthatha Dam
generally maintained close to full supply level as in the past, these variable speed pumps
will not even be required to run for much of the time at all.
The graphs below shows the ground profile along the pipeline route, and at full design
flow, and the hydraulic grade lines, which are shown for both average conditions when the
dam is 65% full 688.7 m (msℓ), and when the dam is close to empty:
12

Figure 5: Hydraulic gradient when dam is close to empty
Chainage, m
By increasing the pipe work diameter in the intake tower, gravity supply from Mthatha
Dam to Thornhill will be possible for extended periods.
It can be seen then that domestic demand, after both the upgrading of supply via the
Thornhill Water Treatment Works, as well as the increase via the proposed Rosedale
Water Treatment Works, this amounts to 29.8% of the assured 1 in 50 year yield of the
Mthatha Dam.
The strategy of increasing pipeline capacity between Mthatha Dam and the Thornhill
Water Treatment Works will also resulted in a significant reduction in power required
under all conditions.
The project to upgrade the supply of water via the Thornhill Water Treatment Works
includes the refurbishment of the existing 800 mm diameter pipeline for some 2,200 m,
and the replacement of the existing 600 mm diameter pipeline which runs parallel to the
existing 800 mm diameter pipeline with a second 800 mm diameter pipeline, As a result
of the need to deviate the last section away from the newly established Phola Park, a new
1,200 mm diameter pipeline, 2,000 m long, will be located along a more secure route to
13
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
the Thornhill Water Treatment Works. This system is designed to convey 1,100 ℓ/s at
peak.
As a result of this increased demand, and noting that should the proposed Rosedale
Water Treatment Works also be supplied with raw water via this intake tower, the peak
demand will increase to some 1,488 ℓ/s. As a result of this requirement for increased
capacity, as well as the very poor condition of the two existing 450 mm diameter manifolds
in the intake tower, it is proposed that these should be replaced with larger diameter pipes
and fittings. It is understood that a project is under way to replace these pipes and fittings.
This is an opportunity for the size to be increased to accommodate additional future flow.
Upgrade and Extension of the Thornhill Treatment Plant
The existing Thornhill Water Treatment Works (WTW) in Mthatha has a treatment
capacity of 60 Mℓ/day. The constraint on the option of supplying all the targeted demands
from the Thornhill Water Supply system is the space limitation at the Thornhill WTW.
Presently it is possible to upgrade the works to ensure supply of water to the 6,500 units
however the future BNG developments (10,500 units) would require further upgrade of the
Thornhill WTW by another 25 Mℓ /D.
The upgrade of the Thornhill Water Treatment Works from 60 Mℓ /D to 80 M ℓ /D forms the
basis of the Phase 1 Upgrading. Furthermore because of the Thornhill raw water
infrastructure constraints and space constraints at the WTW site, the Thornhill WTW shall
not be upgraded beyond the capacity of 120 Mℓ/D.
The additional 25 Mℓ/D to cater for the remaining 10,500 BNG units will be integrated into
the long term strategy and planning for the Mthatha Bulk Water Regional Supply project,
or the Rosedale Bulk Water Treatment Works. The Rosedale Treatment Works is required
for the BNG Phase 1A. This WTW will initially have a capacity of 25 Mℓ/D and will be
increased incrementally through additions of 25 Mℓ/D units until it reaches a full capacity
of 100 Mℓ/D within a 5 year horizon. It is proposed that for operation and maintenance
purposes, the design of the works will be similar to the Thornhill WTW.
The current water supply from the Thornhill Treatment Works is delivered in two
directions, Fortgale to other regional reservoirs, and Ncambedlana (Northcrest) to other
regional reservoirs.
The approach to this option was based on a medium term solution which focused on
improving the system’s operating efficiency from the Thornhill WTW to Signal hill and
Ncambedlana. This approach can be achieved through the upgrade of the Thornhill WTW
and introduction of additional storages at the key zones such as Signal hill, Ncambedlana
(North crest and HL), and Zamukulungisa zones. The actions recommended for this
option are as follows:




Upgrade the Thornhill WTW capacity by an additional capacity of 20 Mℓ/D.
Re zone the Thornhill Water supply system
Increase storage in the system
Replace old bulk mains and valves.
The constraint on this option is the space limitation at the Thornhill WTW. Presently it is
possible to upgrade the works to ensure supply of water to the 6,500 units however the
future BNG developments (10,500 units) would require further upgrade of the Thornhill
WTW by another 25 Mℓ /D.

The additional 25 Mℓ/D to cater for the remaining 10,500 BNG units will be integrated into
the long term strategy and planning for the Mthatha Bulk Water Regional Supply project,
or the Rosedale – Libode Bulk Water Supply. The upgrade of the Thornhill Water
Treatment Works from 60 Mℓ /D to 80 Mℓ/D forms the basis of this upgrading.
Figure 6: Thornhill Water Treatment Works
The Thornhill Water Treatment works is to be designed to cater for the peak week daily
demand (PWDD) which, when working in conjunction with a treated water storage
capacity of 2 days of annual average daily demand (AADD) will ensure that under all
conditions, the reservoirs will have a minimum of 1 day AADD available for emergencies.
It is also assumed that the works would operate over 24 hours per day during peak
periods to deliver the design flow of 84 Ml/d of treated water from the water treatment

The alternatives for increasing the capacity of the system for conveyance of raw water
from the Mthatha Dam to the Thornhill Water Treatment Works have been considered. All
require the use of pumps to provide an adequate service under all conditions, most
particularly when the water level in the Mthatha Dam has dropped during dry periods to
less than 685.0 MSL (Full supply level 692.94, and bottom water level 681.8 MSL). It has
been requested by operational staff, and supported by the results of this investigation, that
standby power is provided at this pump station.
Continued use of the existing system comprising the raw water pump station, and 800 mm
diameter steel pipeline, which requires refurbishment, has the highest running cost as a
result of the electrical power needed. This cost can be reduced by using the existing 600
mm diameter AC pipe, but this is risky as it is reported to be in very poor condition. This
option also does not address the concern regarding the houses in Phola Park being at risk
should there be a failure of either of these pipelines.

REGIONAL BULK INFRASTRUCTURE GRANT

The construction of a new 800 mm diameter steel pipeline, to be laid in parallel with the
existing pipeline, but deviated along a new route to avoid Phola Park, with a new pipe
bridge required was the next most attractive option. Should the philosophy be to
completely replace the existing pipelines, which would be retained for emergencies, a
1,200 mm diameter steel pipeline is selected as the optimum size. However, this option is
relatively expensive compared to the other options available. The combination of a new
800mm diameter steel pipeline to be built parallel to the existing 800 mm diameter
pipeline, with the last section of approximately 1,000 m being rerouted around Phola Park
using a 1,200 mm pipeline was then recommended.
In addition Paradigm Project specialist sub contracted to Anix Trading conducted pipeline
external coating integrity assessment for the existing 4.2 km of DN800 pipeline from
Mthatha Dam Pump station to the Thornhill Water Treatment Works (WTW) and are to
undertake Cathodic Protection (CP) from end, engineering and Design (FEED). The
extent of the pipe damage caused by corrosion and other environmental factors was
assessed using the Pipe Current Meter (PCM) technique. The PCM survey was
conducted from 07 November 2012 to 11 November 2012 from the pump station to the
WTW. A report (Pipeline Refurbishment PCM Survey – Report No PP/ORDT/PCM Report
No 1) detailing the findings and recommendation from the survey was submitted to GIBB,
Amatola Water and OR Tambo District Municipality (ORTDM). A copy of the report is
attached for reference.
From the Pipeline Refurbishment PCM Survey Report, forty five (45) defects warranting
attention were identified along the pipe route. It was also highly recommended that the
entire pipeline be replaced with a new pipeline equipped with a Cathodic Protection (CP)
System.
In light of the above, we concur with the recommendation from the PCM Survey report
that there is merit in replacing the entire pipeline. However, in order to minimise
disruptions to the water supply to Mthatha, we propose that new DN800 steel be laid
parallel to the existing pipe. It is impossible to replace the existing pipe without disrupting
the raw water supply.
Proposal as a result of the detailed investigation of the existing DN800
It was against this backdrop that we propose to lay a new DN800 steel pipe to replace the
existing DN800 steel pipe. The proposed pipe will be laid parallel to the new pipe currently
being constructed by WK Construction under Contract No SCMU ORTDM 10-11/12A MIS
204241/1: Replacement of DN600 with DN800 Steel Pipe. The proposal therefore entails
the construction of a new 2.24 km of DN800 steel pipe and the scope of works is similar to
that of WK Construction.
The emergency pump station located at the Thornhill Water Treatment Works could be
used, but requires the existing equipment to be refurbished. The water has to be made
available by releasing it from Mthatha Dam, requiring careful management so as not to
result in excessive water loss. Consideration was also given to the possible upgrading of
this pump station to increase its capacity. The construction cost of the various options is
summarised below. The influence of running costs is reflected in the table of net present
values that follows. The first column is provided only for comparison, as it is not an option
that can be implemented – refurbishment of a pipeline that is fully utilised is not possible.

SEPTEMBER 2014
Bulk Supply to Fort Gale – Signal hill Zone
Water is pumped from Thornhill Water Treatment Works to Fort Gale reservoirs through
tow (2) No. 600 mm diameter pipes, one is an AC pipe and the other one is a Steel pipe.
The water supply to Fort Gale reservoirs (6 Mℓ, 8 Mℓ and 2 Mℓ) is pumped at the water
treatment plant by four sets of horizontally split centrifugal pumps. The pumps are
currently pumping for 20 hrs. The design duty for the pump (6 & 7 alternating) that pumps
water through the AC pipe is 230 ℓ/s of flow at 127 m head. The pump rated power is 400
kW and pump model is EME 200/250. The design duty for the pump (3 & 5 in parallel) that
pumps water through the Steel pipe is 11 7 ℓ/s of flow at 110m head. The pump rated
power is 225 kW and pump model is 6/8-STGMM. The pumps will need to be upgraded to
cater for future demand to a proposed design duty pump.
Water is pumped from the Fort Gale reservoirs to the Signal hill reservoirs to cater for the
demand. Here two rising mains of 450 mm and 350 mm diameter are used. The 350 mm
diameter pipeline is also used as gravity main when the pumps at Fort Gale are not
running. The approximate lengths of these pipes are 1.60 km and 1.80 km respectively.
These two pipes are connected to a 600 mm diameter steel pipe at the inlet of the
reservoirs.
This system supplies, Zamukulungisa, Zimbane, Town Owen Dam,
Ngangelizwe, and Kwezi zones. The BNG development project would require that
Zamukulungisa, Zimbane, Signal hill zones reservoir and mains be upgraded.
Bulk Supply to Ncambedlana/Northcrest Zone
The water supply to Ncambedlana/Northcrest reservoir (8 Mℓ) is pumped at the water
treatment plant by horizontally split centrifugal pumps. The pumps are currently pumping
for 20 hrs. The maximum operation discharge for the pumps is 140 ℓ/s and the maximum
operation head is 125 m. The design duty for the pumps is 117 ℓ/s of flow at 106 m head.
The pump rated power is 225 kW and pump model is 6/8-STGMM. The pump will need to
be upgraded for future demand to a proposed design duty pump.
The bulk clear water supply from the Thornhill Water Treatment Works is pumped through
a 450 mm diameter rising main to the 8 Mℓ Ncambedlana (Northcrest) reservoir. There are
two supply pipelines from the Ncambedlana reservoir. The first is a 350 mm diameter
gravity pipeline which supplies the Maydene 3 Mℓ reservoir. A further 200 mm diameter
rising main is used to supply the 3 Mℓ Ncambedlana high-level reservoir. The pump
station at Ncambedlana/Northcrest supplying Ncambedlana HL reservoir (3 Mℓ) has two
KSB model WRLN 75 centrifugal pumps. The pump station works on a single duty and
single standby pump system. The design duty for the pumps is 40 ℓ/s of flow at 112 m
head. This system supplies, Northcrest, Hillcrest, Norwood, Ncambedlana, Maydene
Farm and Lower Corana. In order to cater for the proposed BNG development units
within this zone, the infrastructure such as the reservoirs in Ncambedlana HL,
Ncambedlana and Maydene farm together with the 450 mm diameter ThornhillNcambedlana pumping main and the Ncambedlana – Ncambedlana HL pumping main will
require an upgrade.
The challenge and constraint as already stated above was the Raw Water bulk
infrastructure from the Mthatha Dam to the Thornhill WTW and also the availability of
space for the upgrade at the Water Treatment Works. Another limitation was also the
availability of the way leaves for all the proposed upgrades of the existing system. The
optimum option strategically linked to future water resource planning was that of taking
advantage of the proposed bulk pipeline from Rosedale to Libode (Ø=700 mm and Ø=600
mm) sized to allow for off takes into the existing reservoirs and proposed reservoirs within
the Ncambedlana zone. The resulted in the split of Mthatha supply into two bulk supply
17
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
systems divided in their supply zones by the Mthatha River. This option therefore requires
a second Water Treatment works at Rosedale which would supply all the supply areas in
west of Mthatha and also be used for future extensions to other Towns such as Libode,
Mqanduli, Ngqeleni etc.
Planned Bulk Water Infrastructure Upgrade
The planned new project involves the upgrades of Thornhill Water Supply scheme that
was originally designed to cater for 60 Mℓ/D and is now required to cater for 80 Mℓ/D.
These upgrades includes the raw water infrastructure upgrade, the water treatment works
upgrade and the secondary infrastructure such as supply mains and reservoirs that would
be affected by the increase in demand due to the earmarked BNG developments in
Mthatha. The Thornhill water treatment works upgrade will only accommodate the 6500
BNG units and the informal settlement (Joe Slovo, Chris Hani and Nelson Mandela) as
these are currently supplied through the strained Mhlahlane WTW.
It should be noted that there is need for a rollout of the proposed Mthatha Regional
Scheme in order to cater for the remaining 10,500 BNG units and also allow for a split of
Mthatha Water Supply into two systems (Thornhill Water Supply and Rosedale Water
Supply). This rollout would include the detailed design and construction of the new
abstraction point, raw water mains and the Rosedale Water Treatment Works. This
particular Mthatha Regional Water Supply Scheme rollout will form a separate phase to
the proposed Thornhill Bulk Water Supply Scheme Upgrade. The existing infrastructure
and proposed Thornhill Bulk Water Supply Upgrade is shown in Fig. 7

Implementation of the approved business plan
In its capacity as Lead Consultant, GIBB has employed its own staff and is also utilising
the SMME Consultants to manage the project and to provide specialized professional
services, financial management and administrative support to the project. Amatola in its
capacity as the Implementing Agent is providing guidance and also monitoring progress
on behalf of OR Tambo DM. OR Tambo DM has also appointed external professional
service providers and contractors in terms of its supply chain management policies and
procedures.
3.2
Schedules of work and phasing of the activities
The Mthatha Regional Bulk Infrastructure Presidential Intervention project comprises a
number of components, viz. the raw water refurbishment and upgrade, the upgrade and
extension of the Thornhill Water Treatment Plant, and the proposed bulk New Rosedale
Water Treatment works and the Secondary bulk water infrastructure upgrade as described
in Section 3.1 above.
Construction work on the first contracts awarded under Phase 1 commenced in
September 2012, and the last contract is expected to be completed in October 2015.
3.3
Contracts rolled out in the financial year 2013/14 and to be rolled out in 2014/15
Below is a list of some of the contracts that have been/will be implemented during the
2013/14 and 2014/15 financial years. Tables 6.1-6.9 show the status on all contracts.
3.4
Financial Management
Consulting Engineers report monthly on progress and submit invoices to GIBB, appointed
as Lead Consultant then submits an equally valued claim and progress report to the
Amatola Water Board who also submit to the Department of Water and Sanitation’s
regional office in King William’s Town where the necessary approvals and signatures are
obtained for the payment of the invoices and funds into the municipality’s account.
3.5
Co-ordination with other Stakeholders
From a programme management perspective, regular liaison meetings are held between
OR Tambo DM, Amatola Water and GIBB in Mthatha. All relevant stakeholders are
invited to attend, including Councillors.
33
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
In order to co-ordinate all the activities that take place at project level, and to ensure that
effective communication takes place amongst project team members (both internal and
external to OR Tambo DM) and between DWS (in its role as Implementing Agent) and the
officials and councillors of the local and district municipalities, the traditional authority in
the project area, and government officials, two committees have been established, viz:
(i)
(ii)
Project Management Committee (PMC) that deals primarily with technical and
contractual matters, and
Project Steering Committee (PSC) that deals more with institutional and policy
issues.
Sub-PSCs and contract-specific liaison committees have also been established to provide
for good communication and dissemination of project-related information.
Three Community Liaison Officers (CLOs) have been appointed by the civil contractors
involved with upgrade of Raw Water Bulk mains and Phase 1 of the Thornhill bulk water
treatment works.
Other technical co-ordination and ad hoc meetings will also take place, either on a needs
basis, or in terms of generally accepted contract administration practice.
3.6
Risks taken and Management thereof
Due diligence should be practised in ensuring that there is minimum disruption of water
during construction.
3.7
Management of the Programme
The project is managed by a team formed by OR Tambo DM and its team of Professional
Service Providers. The Department of Water and Sanitation (DWS) undertakes the
function of the regulator and funder.
3.8
Capacities Dedicated to the Programme
The capacities dedicated to the programme are as follows:








3.9
Water Services Authority – OR Tambo District Municipality.
Water Services Provider – OR Tambo District Municipality.
Funding – DWS – Regional Bulk Infrastructure Grant (RBIG)

Capacity Building for the Staff within the Programme
The labourers are receiving “in-service” training by the contractors in terms of Health and
Safety, pipe laying, bedding and backfilling.
During implementation, people will be identified that show potential for development and
these people will be given accredited training in the skills for which they show an aptitude.
3.10
Key Challenges within the Project
Key risk areas include the following:
34
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
General:

Future – Possible compensation payable to those dispossessed of their land due
to the construction of the proposed Rosedale WTW. OR Tambo DM will engage
with the relevant affected parties through the Social Facilitator. The details of who
will be funding the compensation and the mechanisms of how and to whom
payment will be made are still uncertain (compensation amounts will be
determined for each corridor first before engagement with funding stakeholders)
Current Contracts:

Rosedale to Libode Pipeline – Slow progress on last 12 km section of pipeline to
Libode under the Dokose Contract. A number of contractual letters in line with
GCC 2010 were issued by the engineer to the contractor and the client.
Contractual processes were followed and in February 2014 a letter of termination
was issued to the contractor. (We are waiting for Amatola Water to advise about
the way forward for this project)

Libode Bulk Supply Pipeline - Contract No: MIS 200542/2- Eskom connections
date remains unresolved. Eskom reportedly stuck on contractor procurement.

Raw Water Pipeline – Slow progress on the DN 1200 Contract under Mbokotho
Investments. A number of contractual letters in line with GCC 2010 were issued
by the engineer to the contractor and the client. Contractual processes were
followed and in February 2014 a letter of termination was issued to the contractor.
(We are waiting for Amatola Water to advise about the way forward for this
project).

MONITORING
4.1
The Monitoring Approach
SEPTEMBER 2014
Primary monitoring and supervision is conducted by the GIBB and other SMME
Consulting Engineers appointed by OR Tambo DM. In addition the Implementing Agent
Amatola Water also conducts. This is done by conducting regular site visits, compiling
monthly progress reports and measurement of quantities of work conducted by the
Contractor. Each contract is controlled by having formal site meetings on a monthly
basis. In addition, contract progress is monitored against the official construction
programme submitted by the Contractor. The data collected from these actions is then
formally recorded and discussed with all stakeholders on a regular basis in order to take
corrective measure when deviations occur.
4.2
Data Analysis and Reports for Implementation Purposes
Reports indicating progress and expenditure are submitted by GIBB to OR Tambo DM
and to DWS.
4.3
Data analysis and reports for performance requirements
Reports are submitted by GIBB to DWS, Amatola Water and OR Tambo DM as required.

PROJECT RESULTS AND BENEFICIARIES
5.1
Outcomes and Outputs
Currently the expected outcomes and outputs are on track for the phase under
construction. Planning for further phases has also commenced through the Mthatha Bulk
Master plan.
5.2
Beneficiaries and Project Results
As stated in Section 2.3 above, the purpose of the project is to ultimately supply 150
Mℓ/day of potable water to a population of 1,000,000 people (approximately 200,000
households), allowing for an increase in the average consumption per capita from 90 ℓ/c/d
to 150 ℓ/c/d over a 20-year time horizon. The Medium Term targets are a supply of 115
36
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
Mℓ/day of potable water to a population of 750,000 people (approximately 150,000
households) and the Short Term target is to supply 95 Mℓ/day to a population of 650,000
people (approximately 130,000 households. The targeted categories of consumers to be
supplied with potable water are domestic water users throughout the KSD Local
Municipality and Nyandeni Municipality, and commercial and light industrial users and
institutional users mainly within the towns of Mthatha, Mqanduli, Ngqeleni and Libode.
It should be noted that GIBB’s Water’s current appointment excludes the connections
between the bulk water supply scheme and the village reticulation systems and any
aspect of the village reticulation systems themselves.
Jobs Created
More than 440 jobs were created to date since construction commenced.

CONCLUSION
6.1
Main Successes and Failures of the Project to Date






6.2
The main challenge has been the delay in the award of contracts that has
significantly affected the targeted delivery of the implementation of the bulk water
provision. However there has been a great participative engagement by
stakeholders and the Lead Consultant to drive the implementation of Phase 1 of
the Scheme. The role-players maintain regular contact with each other, and the
project team, under the direction of DWS, and Amatola Water provides the
necessary professional input.
The extensions of time due to technical difficulties and labour strike have also
added to the delays, but construction work is under way, and Phase 1 of the
project is due for completion by the third quarter of 2014.
The success or failure of the project is likely to depend more on social and political
factors than on technical ones. It is strongly recommended that OR Tambo DM
and KSD LM become more actively involved in resolving ISD issues that have
escalated in frequency and magnitude since March 2012. The proactive and
energetic involvement of both senior officials and politicians is required as a matter
of urgency.
Master planning for the five main corridors for the KSD PI for the next 5 years has
been completed.
To date, a total of 22 contracts falling under Packages 2, 3& 4 have been
awarded.
Draft Tender documents for Package 6&7 have been submitted to Amatola Water
for approval.
Outcomes, Outputs, Successes and Failures versus the Costs
There has been evidence of competitive tendering on all components of Phase 1 of the
Scheme, as indicated by the interest shown by tenderers and generally keen pricing. The
lowest bidder for the construction of the bulk water mains were approximately 30% less
than the Engineer’s estimate.
Most awards were based on contractors that had prices close to the Engineer’s Estimate
so as to discourage large discount that are counter-productive to service delivery as
contractors end up failing to deliver within their tender price.
Local contractors, suppliers and general labour have benefited from this project. In the
Bulk Treated Water Supply System (Phase 1) tender, the target for local joint venture
37
REGIONAL BULK INFRASTRUCTURE GRANT
SEPTEMBER 2014
participation is 15%, and a minimum contract participation goal of 5% for local labour, 5%
for local enterprises, and 5% for local plant hire.
6.3
Ownership and Sustainability of Infrastructure Works
Ownership of all the assets included in the bulk water supply system is to vest in OR
Tambo DM, in its capacity as the Water Services Authority.
Operation and maintenance arrangements for the bulk water supply system are still
required to be finalized by OR Tambo DM especially for the proposed Rosedale WTW
and for the de-sludge process. Currently Amatola Water Board is also offering its support
to the Operation and maintenance of water and sanitation infrastructure for OR Tambo
DM as means of ensuring capacity build up and mentorship development for the
operators.
7
LESSONS LEARNED
Stakeholder engagement at conceptual level where all parties including DWS, OR Tambo
DM, KSD LD and the Professional Team share their views in shaping the project goals
and objects should be encouraged.
It is essential that a fully-functioning Project Steering Committee be in place at the earliest
possible opportunity during the planning stage of the project, and continues throughout
the design and construction stages, with all relevant stakeholders taking an active part in
discussions and conveying project-related decisions to the community at large.
A greater amount of involvement by officials and politicians in local government is
especially required to avoid unnecessary delays due to social resistance to such
developments.
The active participation of the Department of Rural Development and Land Reform is
essential in all land-related issues.
8
RECOMMENDATIONS






It is recommended that urgent attention be paid to the key challenges listed under
Section 3.10 above
GIBB & SMME’s consultants, after approval has been obtained from DWS and its
Implementing Agent, need their fee budgets in the appointment letters to be
adjusted to the scope of work that includes future Phases of the bulk distribution
system, together with the necessary financial allocations.
OR Tambo District Municipality has to ensure sufficient RBIG and MIG funding is
available in order to ensure the bulk water infrastructure is upgraded within the
planned time of implementation.
DWS to support and expedite the water licence approvals
Funding for the full KSD PI (for five corridors within 30km radius of Mthatha) be
made available (approximately R2.5 Billion) through DWS RBIG and MIG.
It is recommended that, after the two DN800 Steel pipes (WK and Anix) have been
commissioned, the existing DN800 Steel pipe be shut down for analysis of the
internal pipe condition.
