CONSULTANTS Project: Water, infrastructure Client: Department of Water and Sanitation Location: Eastern Cape Construction of the Laleni Dam and the Ntabelanga Dam for the Umzimvubu Water Project in Eastern Cape has been announced. The Laleni Dam will be used for hydropower generation. The dam will be able to generate 35MW of baseload power, or up to 180MW of peaking power when operated jointly with the Ntabelanga Dam. The estimated value for the entire water project is R20-billion. The project includes the construction of the 490-million m³ Ntabelanga Dam, to be built in Ntabelanga on the Tsitsa River, a tributary of the Mzimvubu River also for the Umzimvubu Water Project. The proposed Ntabelanga Dam site is located 25km east of the town of Maclear. This site was found to be the best in terms of domestic and irrigation water supplies, and would be used for domestic and agricultural water supply requirements, as opposed to the Laleni Dam’s planned use for hydropower generation. About 18.5km of power lines would also be erected to feed the power onto the national power grid. The detailed design of the Ntabelanga Dam and its associated works and infrastructure is currently under way and was expected Commons Mzimvubu Water Project: Laleni Dam / Ntabelanga Dam The Umzimvubu flows into the Indian Ocean near Port St Johns. to be completed last year, after which construction was expected to start. This would be followed by the intensive construction of bulk water conveyance infrastructure, infield farming infrastructure, and the building of the Laleni hydropower scheme. nn Project: Water, infrastructure Client: Department of Cooperative Governance and Traditional Affairs Location: Cape Town, Western Province South Africa, through the Department of Cooperative Governance and Traditional Affairs, has committed USD37.6-million to water projects in Cape Town following severe drought experienced in the city. According to former Cape Town Mayor Patricia De Lille, the droughts resulted in three years of very low rainfall. The funds will majorly be used for the Cape Flats, Atlantis, and Table Mountain Group Aquifer recharge projects. De Lille also explained at the time that the funds will be reflected on the city’s Informal Settlements, Waste and Water Services department’s budget to be spent in terms of the project delivery plan, following the publishing of the grant in October. It will also reinforce the municipality’s efforts to ensure water security and build a water-resilient city. To help manage the water crisis in Cape Town, the city lowered water restrictions from Level 6B and Level 6, respectively, to Level 5, citing “the encouraging dam recovery and conservation efforts by residents” as the reason. www.civilsonline.co.za USD37.6m committed to Cape water projects Capex has been set aside to resolve Cape Town’s critical water problem. The dams are steadily being replenished by the rainy season and have filled up enough for the strict Level 6B restrictions to be marginally downgraded to Level 5. De Lille however advised that although the city has received “very good” recovery rains, residents should remember to constantly stick to their new relationship with water and continue to both save and use it sparingly. nn CEC January 2019 | 9
