北京市海淀区北部某小区建设于20世纪90年代初,为一重要科研试验区。因周边没有市政供水管网,当时开凿了3眼自备井以满足小区供水。进入21世纪,随着该小区人口不断增加,北京市地下水资源日益减少,而市政供水管网短期内无法接入小区,现有供水系统已无法满足需求,亟待改造。通过对小区自备井供水系统扩能改善工程的探索,找到了一条解决用水紧张的途径,并取得了较好的效果。
A district in the north of Haidian District of Beijing was built in the early 1990s and is an important scientific research pilot area. Due to the lack of municipal water supply pipe network, was drilled three wells prepared to meet the district water supply. In the 21st century, as the population of this district continues to increase, the groundwater resources in Beijing are diminishing day by day. However, the municipal water supply network can not be accessed within a short period of time and the existing water supply system can no longer meet the demand and needs to be rebuilt urgently. Through exploration of expansion project of water supply system of self-owned well in residential area, a solution to water shortage was found and good results were achieved.
