Balcony water diverted for treatment
Print Edition
Jiading District is to invest 15 million yuan (US$2.4 million) in collecting water from balcony downpipes in 40 residential areas in an environmental protection drive.
The sewage water from balconies will be diverted from the rainwater pipe to a separate pipe in the wall which is connected to the water plant for further treatment.
The pipes in kitchens and bathrooms in buildings constructed in 1980s and 1990s are connected to sewage pipes while the pipes on balconies are connected to rainwater pipes.
However, a lot of residents have washing machines on their balconies to save space, thus water rich in nitrogen and phosphorus is discharged into rivers, making them heavily polluted.
So far the project has been carried out in Zhenxin and Jiading Town subdistricts.
In Zhenxin, 63 neighborhoods are expected to join the project by the end of this year. In the first half of the year, the work has been done in 48 neighborhoods. The project in Jiading Town is expected to launch in October.
“We hope property management and real estate management companies will strengthen supervision so that the residents can benefit from the project and the government investment can be effective,” resident Liu Aidong said.
“Long-term management” is frequently mentioned by Jiading’s authorities.
With the upcoming rainy season, much rainwater would be wasted. Industry insiders suggest treating the rainwater and using it in landscaping and industrial cooling to save water resources.
Including balcony water in the sewage system is the first step in water treatment.
“Our city should not be the consumer of water resources alone, it should also become a producer of water resources,” said Lu Jianqing, director of Jiading District Housing Development Center.
