South African Night Flow Analysis Model: SANFLOW

The SANFLOW model is designed to help water suppliers to determine the level of leakage in a particular zone metered area (ZMA) from the analysis of recorded minimum night flows. It is a very simple and straightforward model requiring minimal data and will help water suppliers to identify key problem zones quickly and effectively.

The report: Development of a standardised approach to evaluate bursts and background losses in water distribution systems in South Africa (TT 109/99) is essentially a user guide supporting the SANFLOW model.
