On Thursday, Public Protector Thuli Madonsela said she planned to investigate why residents of Braamfischerville, Soweto, have been occupying wetlands and why officials have been slow to respond to the problem of raw sewage in the streets.
She was visiting the area for the third time.
Residents had complained through the media that attempts to have their grievances heard had fallen on deaf ears.
Engineers from Johannesburg Water are said to be in the process of replacing the entire sewage system, following years of complaints by residents.
Residents have complained that the waste system is a health hazard.
Madonsela said a lot still needed to be done in the area.
“There are two problems: the first problem is the sewerage system which is not working (and) the second problem they have is water drainage.”
