摘要：

Water is piped beneath cities in water mains, sewers, and storm drains. Most, if not all, of these pipe networks leak. Evidence from a ground-water resources study for Lima, Peru and a slope stability study in Hong Kong is presented to show that leakage losses recharge ground water. The contribution of leakage to recharge is shown by ground-water levels, ground-water chemistry, and by water balance and ground-water modeling studies. Estimates of the leakage quantities involved can be developed from water balance and modeling studies, and from analysis of conventional leakage detection tests carried out by water-supply authorities. In Lima, about 40% of the average supply became recharge. Maximum areal rates of recharge for both cities were about 3000 mm/yr.
