South Africa's major cities have confirmed that their sewerage network has been constrained by load shedding and that there is a risk of overflow should it continue.
Mayco member for Informal settlements, water and waste services, Xanthea Limberg says load shedding places a huge risk on operations in terms of water and sanitation services.
Limberg says the City has learned from past mistakes when load shedding was first introduced in 2014 and has since beefed up contingency measures.
The City ensured that all our water treatment plants and sewer pump stations are fitted with permanent generators. This means that we can supply water and sanitation to a significant portion of the city without any major interruptions.— Xanthea Limberg, Mayco member for informal settlements, water and waste services - City of Cape Town
Although the City has contingency plans in place, there is a risk of overflowing at smaller sewer pump station when the power goes off, says Limberg.
She says most of the smaller sewer pumps are fitted with early warning alarm systems which alert the maintenance staff, thereby minimising the risk of overflow.
If we continue seeing severe load shedding in larger areas it might not be logistically possible to prevent any overflow.— Xanthea Limberg, Mayco member for informal settlements, water and waste services - City of Cape Town
