(BEIJING, March 22) -- Beijing municipality has planned to build 10 neutral water plants with a daily capacity of 590,000 cubic meters by 2008, Beijing Daily reported.

In the next three years, main pipes of a total length of 400 km are expected to stretch to urban parks and living quarters to supply neutral water, the paper quoted people with Beijing Water Authority as saying.

The city aims at increasing the use of recycled water to a rate of 50 percent in 2008.

Currently, Beijing's urban area produces some 800 million cubic meters of waste water a year. In 2005, it used 250 million cubic meters of recycled water, or a use rate of 30 percent.

Neutral water refers to a kind of non-drinkable water, which is a result of treatment of domestic waste water.
