遂宁市城区给水管网改扩建工程

为解决遂宁城区给水管网老化、漏损严重、局部地区压力低、供水安全性差等问题，对城区给水管网进行了改扩建，结合城区各水厂的布局和地形特点，提出了分片区供水的改造方案。改造后一年多的运行结果表明，扩建后的给水管网既解决了原有给水管网中存在的问题，又满足了遂宁市城区远期发展的需要，同时第二水厂内泵站的能耗降低了约20％，为供水企业带来了显著的经济效益.

Upgrading and Expansion Engineering of Urban Water Supply Network in Suining City

Upgrading and expansion of urban water supply network in Suining City were carried out to solve the problems of the network such as pipe ageing, serious leakage, low pressure in some area, and poor safety of water supply, etc. Combined with the layout of waterworks and terrain characteristics, reconstruction scheme of sub-regional water supply was put forward. More than one year operation after reconstruction shows that the reconstructed network can not only solve the issues of the original network, but also satisfy the future developing requirement. Moreover, power consumption is decreased by about 20% in the pump station of the second waterworks, which brings prominent economic benefits to the water supply enterprise.
