The precipitation of Beijing is only 345 millimeters this year, which decreased 30 percent compared with the average of regular years. Monitoring from hydraulic department shows that the capital�s water table has reduced 0.6 meter this year.
According to reports made at the conclusion conference of the Sino-German cooperative project, Sustainable Utilization of City Water Resources -- Control of Flood and Pulling of Underground Water, facilities for the utilization of rain and flood have gone into full operation.
The aim of this Sino-Germany project is to collect rain water, including that falls from roofs, pooled in courtyards, roads and greenbelts etc during the rainy season, handle it in a proper way and then either use it directly or send it back to underground.
At present, three exemplary sections of the flood-using project and one testing ground have been built in Beijing. The effect of rain water collection is obvious. The two-hectare project built in the Shuangziyuan Residential Area gathered 440 cubic meters of water during one rainfall. The collected water is used to water the residential area�s 4,028 square meters of green land.
