Rising water table flooding Joburg

Johannesburg – Roads and properties in Johannesburg are becoming flooded from the rising water table, the Star reported on Wednesday.

Underground water was seeping through the roads and causing huge sinkholes and flooding neighbouring properties, according to the newspaper.

Residents were resorting to installing drainage systems at a cost of about R250 a running metre.

If they did not install them, water could get into the foundations of their houses and start eroding them, said Johannesburg Roads Agency (JRA) engineer Andre Nel.

He said the surface water was caused by rain water seeping into underground layers of soil.

It was trapped by a rocky layer, could not seep any deeper, and resulted in a rising of the water table.

The affected areas included Parkwood, Orange Grove and Houghton, Eldorado Park, Roodepoort, Randburg, Soweto and Lenasia.

The JRA would install drainage systems on roads, but did not work on private properties.

Another alternative is to convert the problem into a solution. By harvesting your rainwater at source, you reduce the problem of surface runoff water and secure a constant water supply. This water is then used in the home thus reducing your water bills. Your rainwater tank is fed by your downpipes and has a municipal supply as well for dry periods. The system acts as a backup water supply in times of water outages.
