Forty years ago, the nine tap water factories in Jiading District provided a limited water supply of 58,000 tons a day using local river water. Today, the district’s daily water supply rises to 620,000 tons and high-quality Yangtze River water from Chenhang Reservoir replaces the local river water for the district’s residents.

Jiading now has its tap water company, including four tap water factories, two raw water plants and two regional pumping stations.

It has also built modernized water dispatching stations and water quality laboratories.
