Northwest China's Shaanxi Province will build ten sewage
disposal plants to reduce pollution in the Weihe River, the largest
tributary of the Yellow River, China's second longest river.
The construction of the sewage plants started on Sunday as part
of the provincial government's effort to improve the water quality
of the river.
By 2010, a total of 40 sewage plants will be built to curb water
pollution along the whole Weihe River.
Provincial statistics show that more than 800 million tons of
sewage and wastewater is discharged into rivers in the Weihe basin
annually, about 18 percent of the total in the Yellow River
basin.
The 800-kilometer-long Weihe River originates in Weiyuan County
of northwest China's Gansu province, crosses the western part of
Shaanxi and empties into the Yellow River.
