“We need to look at our infrastructure asset base, there’s huge migration in to Johannesburg. There’s huge demand for basic services housing and water,” Lungile Dhlamini, Managing Director of Johannesburg Water told CNBC Africa.

“In post 1994 South Africa, a lot of investment was sent into serving those [non-serviced] communities,” he said.
While the focus was mainly to service the inequalities of Apartheid, Johannesburg Water has provided 98 per cent of the citizens in the city with pipe water and 94 per cent access to sanitation.
However, problems such as pipe bursts, water leakages and the growing infrastructure are a threat to the progress made since 1994.
“We need a sustained investment for the future, to cater for growth in services,” explained Dhlamini.

“The international rule is to replace two per cent of the [water pipe] network every year,” he explained.
In reference to Singapore which has the best rate of 3.5 per cent increase in renewal of their water network every year. Dhlamini described an extensive 20 year plan to achieve a two per cent increase of renewal of the water network.
