AS Songjiang grows, so does the need for treating an increasing amount of sewage.
The district's seven sewage plants treat more than 430,000 cubic meters of sewage water every day, and that figure is forecast to rise to 520,000 cubic meters when expansion of two existing plants is completed.
Construction work is expected to start this year to expand capacity. The second phase of the West Songjiang Sewage Plant will be able to handle 50,000 cubic meters a day, and the third phase of the East Songjiang Sewage Plan will add 40,000 cubic meters of capacity a day.
The district is also accelerating its network of sewage pipes, with plans to add 10 kilometers more, linking to 200 companies and government buildings.
The local water resource bureau said there are now 790 kilometers of sewage pipes in the district and more than 80 percent of sewage water can be treated. In downtown Songjiang, the proportion has reached 90 percent.
In industrial parks and commercial areas, more than 7,000 enterprises have installed the separate systems to split rainwater and sewage water.
Compared with the downtown areas, village sewage treatment projects are more problematical because of the vast open lands and because of weak awareness among farmers of the need to treat sewage water.
The local water resource bureau has constructed soil permeability systems and combined biological aerated filters and sewage pipe networks in villages, benefiting about 140,000 households.
