According to Fujian Water Investment Group Jinjin Water Supply Co., Ltd., in the six years since the Fujian-to-Kinmen water supply project was launched, the project has continued to operate safely and stably, with water supply volume steadily increasing and cumulative supply exceeding 35 million tons. Since August this year, the project's average daily water supply has been raised to 21,000 tons.

On August 5, 2018, the Fujian-to-Kinmen water supply project was officially put into operation. As of August 5 this year, the project had supplied a cumulative total of 35.4 million tons of water to Kinmen, operating safely for 2,193 days, equivalent to an average daily supply of 16,000 tons, accounting for 81.9% of the total daily water supply of the Kinmen County Waterworks. Kinmen residents' dependence on groundwater for domestic water has dropped from 68.0% to 5.0%.

Hong Jiaxing, general manager of Fujian Water Investment Group Jinjin Water Supply Co., Ltd., introduced that in order to let Kinmen residents drink clean, safe and ecological water, the company has consistently adhered to the principles of "scientific scheduling, guaranteed quality and quantity, safe production and quality service," and has cooperated with the Institute of Urban Environment of the Chinese Academy of Sciences to develop the "Longhu Lake - Application and Demonstration Platform of Algal Bloom Monitoring Technology Based on DNA Molecular Chips," achieving real-time monitoring and pre-treatment of Longhu Lake's water quality and further enhancing the safety guarantee of water quality supplied to Kinmen.

To further improve the level of water supply security, Quanzhou began construction in September 2023 of the Nan'gan Canal Water Supply Replacement Project for Kinmen water supply source security, which is expected to be completed by the end of 2025. By then, the newly built enclosed water conveyance channel will replace the current open high-level canal conveyance method, supplying Kinmen with raw water whose various indicators are further optimized.
