SA Waterbulletin April 1984

Abstract

All local authorities rely almost entirely on surface wetness to detect and locate leaks, notwithstanding the fact that overseas experience points to water losses as high as 75 per cent. To rectify this situation the Water Research Commission has initiated a leak detection research programme in collaboration with the National Building Research Institute of the CSIR. What are the benefits of leak detection? Water saved. This implies higher income per unit for water entering the distribution network. Energy saved as treatment and distribution costs are reduced. Money saved by tackling leaks at source, rather than simply pumping more water into the system and out through leak holes, will pay dividends in reduced need for additional capital expenditure for new facilities and reduced damage to property, roads etc. Capacity saved, thus deferring new facilities. Capital expenditure deferred. Confidence in and knowledge of the supply system are gained enabling better business judgements to be made which are liable to public scrutiny.
