摘要
 
 
 根据丽水市现状及规划要求，老城区的尽量利用原有的雨水管，对局部地区进行适当的改动。新城区的排水系统雨污分流。确定本规划年限为2008年至2020年。规划近、远期及远景划分为：1．近期：2008年-2010年2．远期：2011年-2020年3．远景：2021年以后。编制本规划要从分析丽水市雨水现状着手，从分考虑丽水市环境状况，经济实力和管理水平，几步脱离实际，又必须保证维护生态，保护环境的要求。结合现状，充分发挥城市现有的排水设施的作用，考虑远期规划的合理性，兼顾近期的可行性，便于分期分步实施，使规划具有可操作性。

Lishui City Plan rain
Abstract
 Lishui City, in accordance with the status quo and planning requirements, the old city to make full use of the existing stormwater pipes, some areas of the appropriate changes. New stormwater drainage system in urban sewage diversion. Determine the length of the planning for 2008 to 2020. Planning the past, long-term and long-term is divided into: 1.
