River chiefs in hot water

Four officials were warned by the city government on Friday after the rivers they are in charge of failed quality assessments in March. 

According to a report issued by the river chiefs' office, the north branch of Wuzaogang River in the Pudong New Area and the Shixin River in Jiading District, failed to meet the standards. 

The river chiefs of the two rivers were ordered to immediately take measures to treat the water.

The river chief scheme is a nationwide campaign to improve city waterways.

District directors are appointed as chiefs of the main waterways in the areas under their jurisdictions. Directors of sub-districts or towns are appointed as secondary chiefs responsible for smaller waterways in the area.
