The water quality in Taicang, a county-level city in East China's Jiangsu province, ranked first in the province from January to May, the Department of Ecology and Environment of Jiangsu Province announced on June 25.

This was largely due to the implementation of a series of measures rolled out by authorities, including conducting the river chief system.

The city formulated 10 rules to implement the system, introduced more than 70,000 patrols along its rivers, and established a coordinated treatment system to improve the water quality of its 58 trans-boundary rivers.

The city has also conducted an examination of its sewage treatment facilities to improve their management this year.

The amount of the city's sewage disposal in 2022 was 75.53 million tons, a year-on-year increase of 9.6 percent.
