The meter accuracy degradation rates were determined as 6.67% per year for Model 1, 4.68% per year for Model 2, and 1.45% per year for Model 3 meters. Annual water losses due to meter inaccuracies were 24.1 m3 for Model 1, 16.9 m3 for Model 2, and 5.3 m3 for Model 3, totaling to US$1.5 million every year. This study recommends that degradation rates are used to determine the optimal meter replacement period, and Model 3 meters are the most suitable meters for the KWDS. degradation profiles, Kampala water distribution system, meter accuracy, water, water meters © IWA Publishing 2015 You do not currently have access to this content.
