Thanks to the recent supplementation of precipitation and the continuous replenishment of the mainland's drinking water projects, the water storage capacity of the main drinking water reservoirs in Daishan County has increased slightly. In this period,, Daishan County used the reservoir network joint adjustment project to increase the dispatch of water supply, and the pumping station was running at full capacity to ensure the water demand for life and production after the holiday.

The reporter saw at the Dainan Pingdi Reservoir that raw water from the Yaojiang River in Ningbo flows continuously from the landing point of the third phase of the mainland's water diversion. According to the on-site staff, the raw water is operated by the booster pumping station 24 hours a day and supplied to the two reservoirs of Xiaogaoting and Fengshu respectively. "We are regarded as a transfer station here, and the mainland water diversion is overturned here. We will supply Xiaogaoting Reservoir. In addition to the water diversion from the mainland, the rainwater will come down and turn the water into the reservoir." said Yu Jiaping, director of the Dainan Water Management Station.

It is reported that, in addition to the daily supplement of 30,000 tons of water from the mainland, during the Spring Festival, the county has accumulated 130,000 cubic meters of rivers into the reservoir. Up to now, the available water volume of Daishan County’s main drinking water reservoirs has increased to 1.262 million cubic meters. In the Laoyingkeng recess of the Xiaogaoting Reservoir, the reporter saw that the raw water from the Dainan and Moxin reservoirs was first dispatched to this point through the third and fourth-level flooding operation of the “Reservoir Networking Joint Diversion Project”. Water for production and domestic use.

“The amount of water transferred from Moxin Reservoir to Xiaogaoting Reservoir is 26,000 to 27,000 cubic meters per day. Dainan Reservoir is partly supplemented by water diversion from the mainland and partly supplemented by local water sources. The daily turnover volume is about 24,000 cubic meters." Jinyuan Water Resources Fan Weida, deputy manager of the Investment Co., Ltd., said, “The water supply of Xiaogaoting Reservoir is supplemented by the continuous operation of various pumping stations for 24 hours to meet the water demand of the people on the island.

With the supplement of water diversion from the mainland and the replenishment of river water into the reservoir, the available water volume of the water supply reservoir on Daishan Island is now 874,000 cubic meters. According to the Daishan County Water Conservancy Department, the current daily water consumption of the island is about 43,000 cubic meters. Under the normal operation of water diversion from the mainland, the normal water supply can be guaranteed for 75 days. However, as all industries in the county resume work and production after the holiday, the water supply situation in Daishan County is still not optimistic.

"Although the water storage capacity has increased to a certain extent, there will not be much subsequent heavy rainfall, and the water consumption will continue to increase after the festival. Next, we still need to do a good job of saving water." Water Resources Management Division of Daishan County Water Resources Bureau Jiang Qiaofen said.
