Bulk Water Supply in Limpopo
• The growth points in red are, apart from existing
supplies, currently not addressed by either
Implementation Ready Studies (IRS) or by
constructing of a water resource/services
project.
• The other growth points are covered with an IRS
or a phase of a regional bulk water project is
under construction to alleviate the water problem
• The water resources and transfer schemes are
to support the development of the different
growth points in the province.
4
Bulk Water Supply in Limpopo
All Growth Points must have water supply
schemes:
• A water resource – surface and/or groundwater
• A water treatment plant
• Pump stations
• Regional Bulk – from source to and including
bulk reservoir
• Internal Bulk– from bulk reservoir outlet to
reticulation connection
• Reticulation– from internal bulk end to
household meter
5
Bulk Water Supply in Limpopo
DWA has constructed many major dams in
Limpopo in the past which supply water to
people and other users, namely:
• Nzhelele, Vondo, Damani, Lupepe-Nwanedi in
Vhembe
• Middle Letaba, Ebenezer, Tzaneen, Thabina,
Tours, Blydepoort in Mopani
• Mokolo, Doorndraai, Glen Alpine in Waterberg
• Houtrivier, Chuene, Molepo in Capricorn
• Vergelegen, Nkadimeng, Piet Gouws, Flag
Boshielo in Sekhukhune
6
Bulk Water Supply in Limpopo
DWA is developing the major dams in Limpopo:
• Inyaka (now in Mpumalanga)
• Nandoni in Vhembe District
• Flag Boshielo Raising, and
• De Hoop in Sekhukhune District- construction
50% completed
• Nwamitwa in Mopani District in planning
• Possible dam in Olifants river under investigation
7
Bulk Water Supply in Limpopo
DWA is planning and developing major water
transfer schemes in Limpopo from:
• Inyaka (now in Mpumalanga) to Acornhoek
• Nandoni in Vhembe District to Makhado,
Matoks, Giyani, etc
• Flag Boshielo to Pruissen at Mokopane
• De Hoop in Sekhukhune District to Burgersfort,
Tubatse, Lebowakgomo and Polokwane
(ORWRDP)
• Crocodile river to Lephalale (MCWAP)
• Groblersdal to Moutse West

4. LRGWS – Nandoni Distribution Scheme:
Description & Purpose
• The Nandoni Dam and Distribution scheme forms part of the larger
Luvhuvhu River Government Water Scheme (LGWS) which also
includes the Xikundu scheme
• The project was initiated to provide potable water to the area
between Thohoyandou and Makhado after the completion of the
Nandoni Dam
• The Nandoni Distribution projects were started in 2005 in
conjunction with the Nandoni WTW after completion of the Nandoni
Dam and includes:
– 3 bulk pipelines takes water from Nandoni WTW to various
reservoirs
– NR6 and NN20B pipelines takes water in a northerly direction
– 3 bulk pipelines takes water from Nandoni WTW to various
reservoirs
– NR5 pipeline takes water in a southern and western direction
• Estimated cost for the completion Nandoni Distribution Scheme is
R701 million

DWA approved the accelerated plan to complete the Nandoni
Distribution Scheme’s bulk water pipelines up to the Valdezia Reservoir
Tender for PSPs to redesign the bulk water pipelines did close
Water delivery dates are as follows:
–
Thohoyandou CBD (via NR6 Reservoir and Rising Main) by October
2011
–
Mavambe to Gumbani and Mudabula (via Mavambe to Gumbani
Rising Main, Gumbani Reservoir and Pump Station). Water was
already being delivered as from 17 June 2010 Greater Vuwani
Area(Vuwani (NR7) Reservoir and Rising Main) by August 2012

Bulk Water Supply in Limpopo
FUNDING
• The dams are funded by National Treasury
• Funds not so easily available for RBIG and Reticulation
through MIG
Example:
• De Hoop is funded at R3 billion by National Treasury.
• Bulk Distribution and reticulation to Households require R20
billion.
• R1.2 billion is available from 2007 to 2013 through RBIG and
MIG.
• Shortfall of R18.8 billion is needed to serve 2 million people
and mining.
• Mines and Municipalities not in a position to sign off take
agreements with DWA.
32
Bulk Water Supply in Limpopo
Example:
• RBIG is funding a pipe line from Steelbridge to
Jane Furse – 70% completed
• Sekhukhune DM with MIG is on tender for WTW
at Steelbridge and 10 Megaliter reservoir at
Jane Furse for completion July 2012.
• DWA has to do Phase 2C pipe from De Hoop
Dam to Steelbridge for completion July 2012
depending on funding from National Treasury.
