1.0 Background
Today, in the Democratic People’s Republic of Korea (DPRK), access to sufficient potable water
is limited, threatening the health of many people, young children in particular. Inadequate access
to safe water and poor sanitation services, coupled with poor hygiene practices, are the key
factors contributing to high incidence of diarrhoea among children under 5 in DPRK. Despite of
89 % - MICS 2009 – population having access to piped network in their dwellings - nationally
22 % people above the age of 15 years are involved in collecting water as one of their daily
major activities. There is a geographical dimension to this as nearly 30% rural population collect
water compared to 18% in urban areas. The limitation in water supply is rooted in combinations
of both frequent natural disasters and the lack of systematic repair and replacement of
infrastructure. Recurrent power shortage is another significant problem as country heavily relies
on pump-based systems.
DPRK is blessed with abundant natural water resources, however many sources remain
inaccessible, high up in the mountains, which cover much of the country. In order to address the
growing scarcity of drinking water, UNICEF and other international partners are supporting
Government in replacing the failing pump-based system with Gravity-fed water supply (GFS)
systems. GFS is environmentally-sound and could prove to be a best means of providing clean
water to the majority of people in DPRK. To support promotion of GFS, UNICEF helped
Ministry of City Management (MoCM) in developing a town water supply feasibility study and
design guidelines in 2008 and is being used by all partner agencies. So far twenty County town
water supply systems have been built with GFS technology.
Whilst GFS promotion in the County town is gradually increasing, there is an immense need to
improve the water supply situation in Ris . According to 2008 Census almost 50% of the rural
households fetch water from wells, spring and streams in rural areas either because the existing
systems are derelict and do not function or piped water connection is not available.
2.0 The purpose
The purpose of the consultancy is to support MoCM in developing Rural Water Supply
Feasibility Study, Design and Construction Manual (RWSDC Manual) for the use of County and
Ri level engineers and technicians in designing and constructing the rural GFS systems catering
the needs of wide range of rual settlemts: from a small hamlet with 10 families up to a large rural
Ri with 5000 people. The consultant will also facilitate training of trainers (ToT) to selected
MoCM engineers from County, Province and National levels in the use of RWSDC Manual.
Rural Water Supply Consultancy Notification – UNICEF Pyongyang
3.0 Contents of the RWSDC Manual:
The “RWSDC Manual” will focus on feasibility study, design, construction and operation and
maintenance of small scale GFS systems. The document will provide guidelines, standard
formats, charts and tables to collect all necessary information required from the field to collate
and develop design document manually. The manual will include instructions on how to compute
the hydraulic calculations, sizing of the different structures, and source protection /management.
The hydraulic design of the system has to be done by using the NOMOGRAM in an A4 size
paper or any other easy to refer manual system. The manual will include the details of standard
structures (different types of intakes, collection/sedimentation tank, apparatus such as air release
valve and washouts, interruption chamber, storage tanks, distribution valve chambers, etc)
including pipes and fittings to be installed in these structures. The manual will include detail
design and drawings and fittings of 5m3, 10m3, 15m3, 25m3, 40m3, 60m3, 80m3 and 100m3
storage tanks using RCC. In DPRK, MoCM normally uses PVC and PE pipes for water supply
mains and distributions with GI and brass fittings/valves (CI valves above 75mm) for different
apparatus such as washouts, air-release valve and distributions chambers. This needs to be kept
in mind while working out the fittings.
The document will also discuss in detail the key construction and installation aspects of GFS
system such as civil engineering works (plain concrete, reinforced concrete and plaster) in water
bearing structures and pipe installation and anti-freezing measures in mainlines, valve chambers,
distribution networks and at taps in schools and health facilities.
4.0 Major Tasks to be accomplished
Review rural water supply guidelines and manuals from different countries in the region
with similar geographical contexts and prepare the outline of RWSDC Manual;
Develop a draft RWSDC Manual with detail guidelines, standard formats, charts and
tables to collect all necessary demographic and technical data from the field to collate and
develop manually the design, estimates and bill of quantities of a sound GFS system. The manual
will include instructions on how to compute the hydraulic calculations, sizing of the different
structures, and source protection /management. The document will also address the key
construction, installation and operation and maintenance aspects;
Prepare a trainers training package for engineers involved in training the provincial and
county technicians in designing and supervising the construction of rural water supply systems;
Based on the new training package, facilitate a 6 day long field-based trainers training to
selected MoCM engineers (about 30 persons) on feasibility study, design and construction of
rural GFS systems using the Draft RWSDC Manual;
Working together with PSU of MoCM, finalise the RWSDC manual incorporating
lessons/feedbacks from the trainers training.
5.0 Methodology:
Initially the consultant will work from his or her country of residence in collecting information
and reviewing rural water supply guidelines and manuals from other countries in the region with
similar geographical contexts and prepare a draft outline of RWSDC Manual.
The consultant will present the outline of the Manual to UNICEF and MoCM and further work
on the document with Project Support Unit of MoCM upon arrival in the country of assignment.
The outline will also be shared and feedback obtained from WASH Theme Group members as
The consultant will have opportunities to visit field (2- 3 visits) for practical acquaintances with
various types of water sources (both improved and unimproved) and discuss with county
engineers and technicians. The consultant and MoCM engineers will work together on the
document and prepare a Draft version with all necessary information and tables. The Draft will
be submitted to UNICEF within 15 days of consultant’s arrival in the country.
Consultant will prepare a trainers training package for engineers who are involved in training the
provincial and county engineers in designing and supervising the construction of rural water
supply systems. Based on this package The consultant will facilitate a 6 day long trainers training
to selected MoCM
During this training, the participant will develop a comprehensive feasibility study and design
document for one pilot ri project.
The hands-on trainers training will provide the opportunity to test the practicality of the
document. Working together with PSU of MoCM, the consultant will review the document and
incorporate lessons/feedbacks obtain from the training and finalize the document.
Duty Station:
The consultant will be based in UNICEF office in Pyongyang, however he/she will also be
required to travel to field on as and when needed basis.
