The exploited and utilized quantity of non-conventional water resources in China increases year by year. The non-conventional water resources have become the main source for the landscape use and industrial cooling in the waterdeficient cities in North China. Based on the utilization of reclaimed water, the variations of water-recycling facilities, equipment capacity and productivity are analyzed. Meanwhile, the reasons for overcapacity of reclaimed water are investigated from water supply of water head, terminal consumers, construction of pipeline networks, full cost of water price, own conditions and external environment. Some countermeasures and suggestions are also put forward.
