Effective Pressure Management of District Metered Areas

This paper reviews global practices in pressure management and optimisation as leakage control strategies to reduce water losses in distribution networks. It outlines the methodology and experiences of the Water Board of Lemesos in lowering leakage to economically acceptable levels using advanced pressure control techniques like two-point control and flow modulation. The paper details the steps taken, starting with fixed outlet control and later progressing to flow modulation, achieving further reductions in real losses once DMA conditions were stabilised.
