《加州水法》规定，应鼓励开发水回收设施，以帮助满足该州不断增长的用水需求。利用回收的城市污水进行地下水补给是一种水再利用的方法，可以有计划地增加地下水供应。通过地表扩张盆地或注入井利用再生水进行人工地下水补给的做法正变得越来越重要，在规划未来增加水的再利用时必须认真考虑。包括20个参考文献、表格和图表。

The California Water Code dictates that the development of water reclamation facilities be encouraged as a means to help meet the state's growing water requirements. Groundwater recharge with reclaimed municipal wastewater is an approach to water reuse that results in the planned augmentation of groundwater supplies. The practice of artificial groundwater recharge with reclaimed water by surface spreading basins or by injection wells is becoming increasingly important and must be seriously considered in planning for increased water reuse in the future.
