Benchmarking of Leakage from Water Reticulation Systems in South Africa 2005

The BENCHLEAK model was developed to evaluate levels of leakage and non-revenue water in potable water distribution systems. The first study involved developing the model with a limited budget for checking the various data sets used to test the model. The main objective of the follow-on study was therefore to use the model to evaluate the levels of leakage in approximately 30 water utilities throughout South Africa.

The State of Non-Revenue Water in South Africa

The Non-Revenue Water for municipal water use in South Africa is estimated to be 36.8%. While it is clear that there is significant room for improvement, it is also important to recognize that the South African figure is in line with the World average value of 36.6%.

National Water Resource Strategy 2

The major focus of the NWRS2 is equitable and sustainable access and use of water by all South Africans while sustaining the water resources.

Apparent Water Losses Related to Municipal Metering in SA

Apparent losses consist of water that is delivered to consumers but look like losses to a municipality. It consists of two main components: water meter under-registration and unauthorized consumption. Meter reading and data errors may also contribute to apparent losses.

Benchmark of Water loss, water efficiency and non-revenue water in South African Municipalities.

The aim of this project is to provide the WRC and its stakeholders with a concise assessment of the impact (to date and future potential impact) of the WRC’s Water Administration System on economic, environmental and social aspects of South African and international society.
