Sarwoko Mangkoedihardjo : Indicators for leakage in water distribution system
Prof. Dr. Ir. Sarwoko Mangkoedihardjo MScES
Leakage indicators were assessed for water distribution system with an attempt to provide tools for engineers and decision makers to control water supply. Methods of assessment consisted of head loss, water use fluctuation, peak factor and reservoir volume. An increase of head loss and decrease of peak factor and reservoir
volume are indicators for leakage. A linear increase of leakage resulted in exponential increase of head loss up to the square of leakage level. For Indonesia conditions, there was exponential decrease of peak factor and reservoir volume.
