河北省工农业生产不断发展,对水的需求量也不断增长。近些年来,持续干旱,制约了工农业生产的发展。为了缓解供需矛盾,应开源节流并重,以节流为主。通过节约用水可以延缓供水工程的建设,减少供水排水系统的运行费用和能耗,减少对环境的污染。 The continuous development of industrial and agricultural production in Hebei Province, the demand for water is also growing. In recent years, continued drought has restricted the development of industrial and agricultural production. In order to ease the contradiction between supply and demand, both should be cut in line with the principle of cutting costs and cutting costs. By saving water can delay the construction of water supply projects to reduce the operating costs and energy consumption of water supply and drainage systems and reduce environmental pollution.
