Question NW1973 to the Minister of Water and Sanitation

Reply:

The Rooiwal Waste Water Treatment Works in Hammanskraal does not have sufficient capacity to deal with the amount of sewage flowing into it and has not been well-maintained for many years. The inadequately effluent from the Rooiwal Waste Water (sewage) Treatment Works is polluting the Apies River which flows into the Leeukraal Dam from which water is abstracted by the City’s Temba Water Treatment Works, which provides water to Hammanskraal residents. The Temba Water Treatment Works is supposed to clean the raw water abstracted from the dam and treat it so that it is fit for human consumption. However, the water in the dam is so polluted that the Temba Water Treatment Works is not able to treat the water such that is meets the required standards for drinking water. Hence the people of Hammanskraal have not been having a reliable or safe supply of drinking water for many years.

Since 2011, DWS has taken numerous regulatory actions (non-compliance notices and directives) against the City for it to stop the pollution of water resources in the area from its Rooiwal Waste Water Treatment Works. Since 2019, the Department has been engaged in legal action against the City for a court order to instruct the City to address the issue.

It is possible that the cholera outbreak which started in Hammanskraal in Tshwane is related to the pollution of water sources in the area from the Rooiwal Waste Water Treatment Works. An investigation is underway into the source or sources of the cholera outbreak. Technical teams from the Department of Water and Sanitation, and the provincial and national Department of Health as well as relevant municipalities are carrying out water quality tests at distribution points and at water treatment works in areas in Hammanskraal where people have become infected. They are also engaged in tracking and tracing of infections. Cholera has not yet been identified through the tests. The Water Research Commission has also commissioned a verification of the DWS and CoT tests as well as independent tests, the results of which should be available shortly. It is important to note that cholera is not only spread through polluted water – it is also spread through poor hygiene, eating contaminated food or by coming into contact with the faeces of an infected person. To date, the original source of the cholera infection has not been located.

The City has warned the residents of Hammanskraal) not to drink the water from the Temba water treatment works (which is the water coming out of taps in Hammanskraal) and is supplying them with drinking water from tankers. The water tankers abstract water from Magalies Water and Rand Water sources, which is compliant with drinking water standards.

In the light of the cholera outbreak it is imperative that the repair and upgrade of the Rooiwal WWTW be dealt with as a matter of national urgency. DWS does not have voted funds to provide to Metros for water and sanitation. Metropolitan municipalities are supposed to use a portion of their USDG grant to supplement their own budget allocations for water and sanitation.

DWS has estimated the cost of a full rehabilitation and upgrade of the Rooiwal WWTW over the next three financial years to be in the region of R4 billion. The project can be implemented in stages, with an emphasis on work to stop or reduce the pollution from Rooiwal in the early stages.

The Mayor and the City have indicated that the City does not have the capacity on its own to address the sanitation challenges, nor does it have sufficient funds to address the challenges timeously on its own. The Mayor has also indicated that the City’s SCM processes are corrupted.

In this context, the CoT, DWS and National Treasury have recently agreed that:

• The DWS and the City will partner together to jointly manage a project to fix the Rooiwal WWTW in Hammanskraal.
• Tshwane will contribute a portion of its USDG allocation. Council approval for R450 million to be allocated over the MTEF has been granted.
• The DBSA will be appointed by CoT as the implementing agent for the project.
• A financial task team consisting of NT, DWS, the City and DBSA has been put in place to develop a financing plan for the project. Various options are being considered, including but not limited to, increasing the City’s contribution from its USDG allocation, shifting funds from other grants, and DBSA loan finance.

DWS and the City will have formed a joint technical steering committee to oversee the project.

In the short-term, an alternative drinking water source will be put in place by Magalies Water for Hammanskraal through the emergency construction of a 30-40 Ml/day package-plant at Klipgaart WTW. The plant will provide drinking water in the Hammanskraal water distribution system. The Package Plant will be implemented in a phased approach with 10Ml/day at a time. The units will be in place starting from October 2023 at Klipgaart WTW and will be completed by March 2024.

In the meatime, CoT will continue with mobile water tankering services for Hammerskraal residents, from designated water filling points, with regular testing of water provider from tankers. Community structures will be requested to participate in a structure with the City to monitor the tankers and testing of water from the tankers.

The repair and upgrading of the Rooiwal will be implemented in phases which will be run concurrently, between September 2023 and June 2026. The upgrading will result in an increase in the capacity of Rooiwal from 250 ML/day to 380 ML/day.
