Authority assumes bigger role in six critical water projects


Staff Writer


TCTA has been called upon to play an even greater role in the rollout of critical water infrastructure across South Africa. The expanded mandate will take the form of programme management services in respect of six proposed projects: De-Hoop, Mzimvubu, Loskop, Xhariep, Mkhomazi and Clanwilliam.


To this end, the Authority is expected to leverage its resources and capabilities to augment the capacity of its parent department, Human Settlements, Water and Sanitation. The specific areas of required support entail programme planning and coordination in implementing water infrastructure development.


The Department hopes that the TCTA intervention will resolve the challenges it is now experiencing on its projects. These are in areas including project preparation, roll-out and delivery to specifications, on time and within budget. Furthermore, the changes to the way major water infrastructure projects are managed aim to eliminate corruption. 


Broader infrastructure development is the central plank of the government’s effort to transform all facets of the South African society, particularly in respect of economic development and social wellbeing.


The Authority received the Directive to provide infrastructure planning and management services for the six projects on 1 April 2019.


  • The Directive shall be implemented in line with all applicable laws and the new implementation model,” former Water and Sanitation Minister Gugile Nkwinti said on issuing the Directive. The new model promoted effective utilisation of the Construction Unit in the implementation of the managed projects and socio-economic transformation in the execution of projects.


Engagements are ongoing with the Department of Human Settlements, Water and Sanitation to finalise the scope of the work that TCTA will assume in the projects.




De-Hoop Water Project

The dam was built is to supply water to the towns, industries, particularly mines, and rural communities in Sekhukhune, Waterberg and Capricorn districts of the Limpopo province. Additional bulk water distribution infrastructure is planned to provide water to even more users in the precinct.

Mzimvubu Water Project

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.


Loskop Water Project

The project entails the construction of a new bulk water scheme and will be undertaken in three phases. The initial target is the abstraction of 20 Ml/ day from Loskop Dam for the benefit of about 30 000 households.


Xhariep Water Project

A bulk water system will be designed and constructed from Gariep Dam to Bloemfontein. It will secure long-term water supply to Mangaung Metro and the associated towns and diversify the access to water resources, optimise cost and bring about improved efficiencies.


Mkhomazi Water Project

Phase 1 of the project consists of a new dam at Smithfield on the uMkhomazi River and a conveyance infrastructure (tunnel and pipeline) to the proposed water treatment works (WTW) in the uMlaza River valley. A gravity pipeline from the proposed WTW to the UW bulk distribution system, connecting in the area of the Umlaas Road reservoir, also is planned. From Umlaas Road, water will be distributed under gravity through existing infrastructure to eThekwini.


Clanwilliam Water Project

The project entails raising the full supply level of Clanwilliam Dam by 13 m to improve the safety of the structure, including the construction of a new inlet tower and outlet works. The annual yield of the dam will be increased by 70 million m3, of which a portion will be made available to assist in the development of a resource for poor farmers. The project will further upgrade and expand the existing conveyance network to distribute water downstrea
