AQUALITE is the first of a new generation of models designed to assist water suppliers in managing their non-revenue water. It is effectively an annual water-audit model based on the latest IWA best practice. It has been developed through close co-operation of numerous internationally recognized water loss managers from several countries and incorporates a host of features, many of which are not available in other water audit models.

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.
