Poorly maintained sludge near the drying beds
The final discharged effluent was turbid and almost black, still contaminated with solids.
Ratau said the DWS’s investigations into the pollution Mdloti River began mid-December, resulting in Section 19 compliance letters being slapped on eThekweni municipality and Verulam WTWW. In layman’s terms, a Section 19 compliance order is the first step of a legislative process that could lead to prosecution if parties responsible for management of a plant such as Verulam ’s WWTW fail to take comply with laws governing waste treatment.
The DWS’s intervention – and now tough stance – followed several months of complaints lodged with local authorities by residents of Mr Morelands Estate, but little action being taken.
Foamy, dark water
Putrid smells continued emanating from the river, and in December the water turned foamy and dark, and rocks at the bridge going into Mount Morelands started gathering a white residue – a clear indicator of sewer pollution. Upstream of the Verulam WWTW, situated near Mt Morelands, the water appeared clean.
In alerting Roving Reporters, Ray van der Poll, a canoeing enthusiast and owner of eco-lodge, Shapes for Africa, said he when had visited the Verulam WWTW in mid December the place was place deserted.
“It seemed everyone had gone on leave,” said van der Poll.
On December 19, the provincial department of Water and Sanitation initiated their investigation, taking water samples below and above the Verulam plant. High levels of E.coli were found downstream of the plant.
The plant itself was found to be in an unacceptable state, said Ratau, who provided photographs of DWS’s inspection. These showed a high level of scum on the plant’s primary settlement tank, poorly maintained sludge near the drying beds, and solids in the chlorine contact tank. The final discharged effluent was turbid and black in colour. All this led to Section 19 compliance letters being issued, meaning that if poor management of the plant and ineffective treatment of sewerage was not addressed, those responsible could end up in court.
In meantime, Van der Poll said the water in Mdloti river had much cleaner of late, so much so that he had completed his training for this weekend’s FNB Dusi Canoe marathon in the Mdloti river and La Mercy lagoon.
