南水北调中线与东线受水区城市生活节水分析

Urban water saving analysis for water supplied regions on the middle and east routes of South-to-North Water Transfer Project/

根据先节水后调水的原则,对南水北调中线与东线受水区的城镇生活用水和节水现状进行分析,总结该地区的生活节水成绩,指出与世界先进节水水平的差距和节水潜力.在现状分析的基础上,根据《中国城市节水2010年技术进步发展规划》,提出该地区2010年和2030年的城市生活节水目标及其相应的节水措施,并进行需水量和节水量估算.最后对节水投资与效益进行估评,证明节水效益巨大,且投资远低于自来水厂供水投资.

Based on the principle of water saving first and water diversion later, an analysis is made of the current situation of domestic water consumption and water saving in the water supplied regions on the middle and east routes of the South-to-North Water Transfer Project. The achievements of water saving in these regions are summarized, and their potentials in water saving and the gap between the level of these regions and the world advanced level are pointed out. According to “2001’s development planning for technological progress in urban water saving in China”, the target of urban water saving from 2010 to 2030 for these regions and corresponding measures are put forward, and the volumes of water to be required and to be saved are also predicted. It is verified that water saving in these regions has generated great benefits, and the investment is far lower than that for the construction of water supply plants.
