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.
