NNADOZIE, RC. Access to adequate water in post-apartheid South African provinces: an overview of numerical trends. Water SA [online]. 2011, vol.37, n.3, pp. 339-348. ISSN 0378-4738.
This paper presents an insight into water service access and demand, with a numerical review of official data from the national household survey from 1995 to 2006, and the 1996 and 2001 census data. The findings show that in provinces (Eastern Cape, Limpopo and Mpumalanga) where the existing service base is low, with a relatively high level of outmigration leading to a decrease in household numbers, the annual rate of delivery is lower than in other areas and percentage access has risen marginally (from about 68% to 70%). In provinces (North West, Northern Cape and KwaZulu-Natal) where the existing service base is higher, with relatively lower levels of out-migration, there is a marginal change in household numbers and the annual rate of delivery is higher and percentage access has risen remarkably (from about 72% to 88%). In the provinces (Gauteng, Western Cape and Free State) with the most favourable initial conditions, that is, where the existing service base is the highest, there is a remarkable change in household numbers, possibly as a result of in-migration and the annual rate of delivery is quite sustainable. Percentage access rises at an early stage and remains stable at the limiting value of about 98%.
