Flooding and water wastage: Apartheid-era planning and a lack of stormwater management to blame

Flooding in certain areas in the country has given the impression that sufficient water is gained during heavy rainfalls. But in fact, the rain has minimal impact. In Gauteng, it is partly because the Vaal Dam is serviced by dams in the Free State, Lesotho, KwaZulu-Natal and Mpumalanga. This renders the Gauteng contribution insignificant, even during heavy rainfall seasons.

The geomorphology of the province is such that the rain that falls north of Sandton flows in a north-eastern direction, towards the Hartbeespoort Dam, through the Crocodile River and towards the Limpopo River. Similarly, the north-eastern part of Gauteng, the east of Cullinan, has the rainwater flowing towards the Letaba and upper-Olifants catchment area.

Understanding Gauteng’s geomorphology is the right step towards building effective stormwater management systems. However, this will require large investments to be made. The current system is a result of apartheid spatial planning and continues to put the lives of citizens in danger. There are no drainage systems in place for flooding conditions, which are becoming frequent due to climate change.

Due to apartheid spatial planning, Centurion’s infrastructure has been built on wetland and flood plains around the Hennops River. In the case of Mamelodi, the land has been altered to such an extent that it has no ability to hold the water. The area was allocated to black people by the apartheid government, which deliberately built the houses so close to the Edendalespruit River, it altered the riparian zone i.e. the areas adjacent to the river. The riparian buffer zone should not be interfered with in order to reduce the risk of flooding. The natural assimilation capacity of the natural water resources has been disrupted to such great lengths that it cannot manage the extra influx produced by heavy rains. Citizens alongside the Jukskei River face the same effect. These areas both remain vulnerable to flooding, with all the corresponding risks of disease and homes being washed away.

Ah if it floods regularly, move away. Durban had the same issue with the umgeni many many years ago until the city stepped in and said no more shacks etc alongside the river.

Pretty sure weather patterns have changed in the last 30 years but either way, that poor poor horse.

Wow, that's a new kind of stupid author!? Rather surprised to see it on Daily Maverick. Not listed on today's home page.

Except they're losing that fight as well, if you look at the Quarry Road West Settlement down the bottom of the M19, the guys are building right on the edge of the river there...

Its free housing they have to rebuild at least once a year though, when there are heavy rains (which seems to be almost a national standard these days)

Sounds like they want the Apartheid government back to run things. Clearly the anc cant manage.

Was there ever any doubt, these Muppets could not run a bath? With the incompetent currents at the helm, one needs to decimate one's expectations.

the apartheid era planning is probably the only reason **** still stands today.

other places build entire functioning cities in less than half the time the current clowns have been in charge of a country they were given on a golden platter. but no, the clowns demand more. break and demand, break and demand.

blame history when they do nothing today.
