Effective management of water supply systems consists in supplying adequate quantities of clean water to the population. Detailed pilot studies of water distribution systems were carried out in 9 cities in India during 1971-81 to establish the feasibility of a programme of assessment, detection, and control of water losses from supply systems. A cost-benefit analysis was carried out. Water losses from mains and service pipes in the areas studied amounted to 20-35% of the total flow in the system. At a conservative estimate, the national loss of processed water through leaks in the water distribution systems amounts to 10(12) litres per year, which is equivalent to 500 million rupees.It is possible to bring down the water losses in the pipe mains to 3-5% of the total flow, and the cost incurred on the control programme can be recovered in 6-18 months. Appropriate conservation measures will help in achieving the goals of the International Water Supply and Sanitation Decade to provide clean water for all.
供水系统的有效管理在于向民众提供充足的清洁用水。1971年至1981年期间，在印度的9个城市对配水系统进行了详细的试点研究，以确定评估、检测和控制供水系统水损失计划的可行性。进行了成本效益分析。在所研究地区，主管道和服务管道的水损失占系统总流量的20%至35%。据保守估计，全国通过配水系统泄漏损失的处理水达每年10（12）升，相当于5亿卢比。有可能将主管道的水损失降至总流量的3%至5%，控制计划产生的成本可在6至18个月内收回。适当的节水措施将有助于实现国际供水和卫生十年为所有人提供清洁用水的目标。
