On November 28, the main structure of the Dagongqiao Water Buffering Tank was capped. The largest building in Yichang City's drainage network, the underground tank is a key component of the city's upgrade to its sewage system.
Phase 2 of the 3.9 billion Juan (US$ 550 million) sewage project began in March 2021. It involves the inspection and dredging of existing sewage pipelines and the expansion of the existing network, with the addition of new facilities.
The water buffering tank has a capacity of 21,000 cubic meters, equivalent to the volume of 10 standard swimming pools. During heavy rainfall, it will collect waste water overflows. On dry days, it slowly releases the overflows into the downstream sewage treatment plant.
Once finalized, the buffering tank will reduce the pressure from early stormwater peaks on the urban water supply and sewage systems and alleviate the risk of urban waterlogging. It will also minimize rainwater pollution of the Yangtze River caused by the initial waves of rain water, known in the sector as the first "foul flush".
The city’s sewage upgrade project is being undertaken by the Xiaoting District government and the China Three Gorges Corporation. It is one of the pilot projects for the protection of the Yangtze River.
