渭南市水资源匮乏。自产水资源为２０．０６亿ｍ３，人均、亩均水资源占有量低。１９９４年全市总用水量为１４．５７亿ｍ３，缺水４亿ｍ３，因干旱缺水农业减产粮食５３万ｔ。为了适应渭南市《“九五”计划纲要和２０１０年远景目标》经济发展的需要，提出要加快过境地表径流的开发利用，近、远期将扩大供水３．３亿ｍ３和７．３亿ｍ３；节水是水资源利用的薄弱环节，通过农业节水，工业节水，在远、近期可节省水量６．５亿ｍ３和８．５８亿ｍ３。通过上述措施使渭南市水资源供需基本平衡，大大缓解缺水问题
Weinan lack of water resources. The self-produced water resources are 2.206 billion m3, and the per-capita and per-mu water resources share is low. In 1994, the total water consumption in the city was 1,457 million m3 and the water shortage was 400 million m3. The output of grain was reduced by 530,000 tons due to drought and water shortage. In order to meet the needs of economic development of the “Ninth Five-Year Plan” Outline and the 2010 Vision Target in Weinan City, it is proposed to speed up the development and utilization of surface runoffs in the border area. Water supply will be expanded by 330 million m3 and 730 million m3 ; Water saving is the weakest link in the utilization of water resources. Through agricultural water saving and industrial water saving, water savings of 650 million m3 and 858 million m3 can be saved in the far and near future. Through the above measures to make the basic balance of supply and demand of water resources in Weinan City, greatly ease the problem of water shortage
