This paper analyze of the present situation of the water supply system in the rural area of Beijing city. Based on the investigation and statistical data, it was established that integrated domestic water consumption ranged between 30 and 120 L/cap.d in Beijing rural area. Most of the villages had developed underground water for residential use. More than 97% of the villages that had a surface water source had a contamination problem. More than 81% of villages with a constructed pipeline had an aged or corroded water supply pipe system, along with partial or even serious pipe leaks. 29.5% of all the villages have a decentralized water supply system and 70.5% have a centralized water supply as well. The centralized water supply system service rate reaches 78.7% of villages in all, and the tap beneficial rate is 95.7% The water of above 97% villages does not meet the requirements of the Drinking Water Sanitation Standard, thus the problem of the instability of water quality should be addressed. If a reconstruction and improvement strategy were to be made, the water source, water distribution system, water supply mode, water quality and water pressure would be highlighted. It will guide the way to water supply system reconstruction and improvement of villages in Beijing.
