Two multi-purpose dams and associated infrastructure, Ntabelanga and Lalini dams, on the Tsitsa river which is a tributary of the Mzimvubu river, will be developed to provide for potable water supply, irrigation, hydropower and tourism. Due to the catalytic role the project is expected play in the broader socio-economic development of the region, Government has classified the project as a Strategic Integrated Project under SIP-3.
uMkhomazi Water Project (uMWP)
The Mgeni System is the main water source that supplies about six million people and industries in the eThekwini Metro, Msunduzi Local Municipality, Ilembe, Ugu and uMgungundlovu District Municipalities’ areas of jurisdiction, all of which comprise the economic powerhouse KwaZulu-Natal. Water requirement projection indicates that the
Mgeni System is anticipated to experience a deficit and therefore there is a need for new water resources, uMWP-1.
Programme Management Services to DWS in relation to Water Infrastructure Projects.
On the 1 April 2019, TCTA received a Directive to provide programme management services to the Department of Water and Sanitation (DWS) on the following water projects:
De-Hoop water project
Mzimvubu Water Project (MWP)
Loskop water project
Xhariep water project
Mkhomazi water project and
Clanwilliam water project
PROJECT IN CONSTRUCTION PHASE
Olifants River Water Resources Development Project (ORWRDP)
ORWRDP-2 bulk distribution system (BDS) - to transfer water from the De Hoop and Flag Boshielo dams for municipal and mining needs in the middle Olifants river catchment area, unlocking significant social and economic development. Phase 2C will improve water supply to Jane Furse / Nebo Plateau and for mining activities in the Steelpoort - Burgersfort area. Phase 2C
comprises a 40km pipeline from the De Hoop Dam to Steelpoort and a pump station.
Off-take pipeline to town of Kriel
The off-take pipeline to the town of Kriel will provide backup for water supply especially when the current water supply pipeline from Jericho Dam is out of service for scheduled repairs.
The project consists of the construction of a 3km pipeline connecting from the KWSAP Duvha pipeline and an upgrade of the existing Kriel water treatment works.
Acid Mine Drainage - Long Term Solution (AMD-LTS)
Saline water discharges from the AMD short term intervention into the Vaal River System (“VRS”) necessitates frequent dilution releases from Vaal Dam. VRS could face severe water supply limitations which may result in reduced or curtailed dilution releases – impacting negatively on water users in the Middle and Lower Vaal and Orange River System catchment areas.
Implementation of the AMD – Long Term Solution project will obviate the need for dilution releases from the Vaal Dam. Desalinated AMD from the Witwatersrand will augment water supply to the VRS.
PROJECTS IN ClOSE-OUT PHASE
Mokolo and Crocodile Water Augmentation Project (MCWAP)
MCWAP-1 consisted of acquisition of the old Exxaro Scheme and construction of a 43km of pipeline and pump station to deliver bulk raw water from the Mokolo Dam to Medupi and Matimba power stations, Exxaro and Lephalale Municipality. It also includes refurbishment of the old pipeline from Mokolo dam to the Matimba supply point.
Acid Mine Drainage - Short Term Intervention (AMD-STI)
The project entails implementation of the short-term action plan, as recommended by the Inter-Ministerial Committee, in the Western, Central and Eastern Basins of the Witwatersrand Goldfields. The short-term action plan is to prevent decant in the Western Basin and the environmental critical level (ECL) from being breached in the Central and Eastern Basins catchment area.
Short term intervention consisted of upgrading the existing Western Basin water treatment plant and construction of two new high density sludge (HDS) water treatment plants in the Central and Eastern basins.
Mooi Mgeni Transfer Scheme (MMTS)
MMTS-2 entailed the construction of a 37.7m high dam with 139.5 million-m3 storage capacity; a pump station and 14.9km pipeline including 8.3 km of Umgeni Water (UW) potable pipe; and the refurbishment of MMTS-1.
MMTS-2 augments the yield of Mgeni System by 60 million to 394 million m3 per annum. The water benefits e-Thekwini Metropolitan Municipality, uMgungundlovu District Municipality, Msunduzi Local Municipality, Ugo Municipality and Ilembe Municipality representing the economic hub of KZN and will increase water security in the area.
