The dams not only provide a steady source of drinking water, but also have further social and economic benefits. They provide irrigation for cash crops and other commercial rural activities, piped water for industrial activities in nearby villages. Further due to the large number of dams, the water table rises over a large area and therefore stimulates ecological regeneration. 水坝不仅能提供稳定的饮用水源，也能带来更深远的社会和经济利益。它们能为经济作物及其它农村商业活动提供灌溉，也为邻近村庄的工业活动提供自来水。而且，由于水坝数量众多，大区域的地下水位升高，因此促进了生态复兴。
