4 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 problemThe water resources and transfer schemes are to support the development of the different growth points in the province.
5 Bulk Water Supply in Limpopo All Growth Points must have water supply schemes:A water resource – surface and/or groundwaterA water treatment plantPump stationsRegional Bulk – from source to and including bulk reservoirInternal Bulk– from bulk reservoir outlet to reticulation connectionReticulation– from internal bulk end to household meter
6 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 VhembeMiddle Letaba, Ebenezer, Tzaneen, Thabina, Tours, Blydepoort in MopaniMokolo, Doorndraai, Glen Alpine in WaterbergHoutrivier, Chuene, Molepo in CapricornVergelegen, Nkadimeng, Piet Gouws, Flag Boshielo in Sekhukhune
7 Bulk Water Supply in Limpopo DWA is developing the major dams in Limpopo:Inyaka (now in Mpumalanga)Nandoni in Vhembe DistrictFlag Boshielo Raising, andDe Hoop in Sekhukhune District- construction 50% completedNwamitwa in Mopani District in planningPossible dam in Olifants river under investigation
8 Bulk Water Supply in Limpopo DWA is planning and developing major water transfer schemes in Limpopo from:Inyaka (now in Mpumalanga) to AcornhoekNandoni in Vhembe District to Makhado, Matoks, Giyani, etcFlag Boshielo to Pruissen at MokopaneDe Hoop in Sekhukhune District to Burgersfort, Tubatse, Lebowakgomo and Polokwane (ORWRDP)Crocodile river to Lephalale (MCWAP)Groblersdal to Moutse West

23 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 schemeThe project was initiated to provide potable water to the area between Thohoyandou and Makhado after the completion of the Nandoni DamThe 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 reservoirsNR6 and NN20B pipelines takes water in a northerly directionNR5 pipeline takes water in a southern and western directionEstimated cost for the completion Nandoni Distribution Scheme is R701 million
25 4. LRGWS: SCHEDULEDWA approved the accelerated plan to complete the Nandoni Distribution Scheme’s bulk water pipelines up to the Valdezia ReservoirTender for PSPs to redesign the bulk water pipelines did closeWater delivery dates are as follows:Thohoyandou CBD (via NR6 Reservoir and Rising Main) by October 2011Mavambe 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 2012Valdezia Area (Valdezia Reservoir and Rising Main) by November 2012Mushiri, Mahagala and Lambani (Lambani Gravity Main) by October 2011Peri-urban areas east of Thohoyandou (NN20B Reservoir and Rising Main) by October 2011The water from the bulk distribution systems will feed into the existing local reticulation systems

32 Bulk Water Supply in Limpopo FUNDINGThe dams are funded by National TreasuryFunds not so easily available for RBIG and Reticulation through MIGExample: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.
33 Bulk Water Supply in Limpopo Example:RBIG is funding a pipe line from Steelbridge to Jane Furse – 70% completedSekhukhune 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.
