HUGE HEALTH RISK! Raw sewerage flowing into Somerset West residential properties

Since 20 June 2018, we have logged at least 8 calls to the CoCT due to raw sewerage pushing into our residential property. On each occasion a temporary fix is implemented by staff unblocking the blockage in the roads, but every time raw sewerage pushes out inside our property with no-one but us having to replace lawn and clean (despite water restrictions) the raw sewerage to ensure my dogs don't end up consuming it and my children don't have to play in raw sewerage. On 8 August we logged a request for a stop/reverse valve to be installed (ref no ********** 760) but to date we had 3 more raw sewerage incidents and no feedback. Even Mr. Stuart Pringle was approached, but nothing resolved. We keep getting sent from pillar to post without resolution and having to incur costs at our expense. Surely this is a huge health risk for all tenants and animals in the area
