跟著我國經濟社會快速發展、人口持續增長和城鎮化率逐步進步，城市集中供水需求逐年增大，目前的服務規模大約籠蓋5億人口。然而，飲用水源所在區域的產業、糊口和面源污染給水源環境質量帶來了很大的威脅。

      《規劃》對全國655個設市城市及縣級政府所在地城鎮4002個集中式飲用水水源地水質和環境治理狀況進行了全面評估，發現飲用水水源保護工作中存在的水質達標率較低、保護區劃分與治理不規范、監測及應急能力薄弱等題目。城鎮集中式飲用水水源地的水質調查顯示，有近1/5的水源存在污染物超標現象。而目前，飲用水水源地的環境治理還主要污染物，有毒有機污染物的監測與治理在大多數地方尚未納入工作范圍。

      《規劃》提出了“以防為主、防治結合、統籌規劃、綜合管理、凸起重點、分步實施、立異機制、加強監管、明確職責、強化考核”的水源環境保護原則，明確了全面改善集中式氣浮飲用水水源環境質量狀況、晉升水源應急監測及應急供水能力，知足2020年小康社會對水源水質安全的需求等總體目標，并進一步將規劃目標分解為水質、保護區劃分與治理、保護區氣浮設備整治、水源地監管能力共4類5項指標。 

With the fast economic and social development, population growth and urbanization rate gradually progress, urban centralized water supply demand increased year by year, the service scale LongGai about 500 million population. However, drinking water source area of the industry, mouth and non-point source pollution to water environment quality has brought great threat.

"Planning" for the country's 655 city and county town government is located 4002 centralized drinking water quality and environmental governance has carried on the comprehensive evaluation, found existing in the drinking water sources protection work division and water quality success rate is low, the reserve management is not standard, monitoring and emergency ability weak and so on questions. Urban centralized drinking water source, water quality survey, nearly 1/5 of the water pollutants exceeds bid phenomenon. And at present, the water source of drinking water environmental governance is still limited to the main pollutants, toxic organic pollutants monitoring and management in most places have not been included in the scope of work.

"Planning" proposed "to prevent, control and overall planning, comprehensive management, bump key, step-by-step implementation, set different mechanism, strengthen supervision, clear responsibilities, strengthen examination" of the water environmental protection principle, has been clear about the overall environment quality conditions improve centralized drinking water sources, water source emergency monitoring and emergency water supply ability promotion, content of 2020 well-off society demand for water source water quality safety, etc. The overall goals, and further planning target divided into water, reserve and the supervisory ability of the water source of governance, level of reserve management, a total of four class five indicators.
