[Explanation] Residents in Zhangye, Gansu have been guarding the Qilian Mountains since ancient times, but how to drink high-quality Qilian snow water and make better use of surface water resources to save groundwater has always been a "difficult problem" for urban residents.
It was not until the recent period that the construction of an urban backup water source in Ganzhou District of Zhangye City was completed and officially supplied water to the local area, which allowed 280,000 residents to bid farewell to the history of drinking groundwater for thousands of years and drink more high-quality, clear surface water.
A few days ago, Ding Hui, chief engineer of Zhangye Water Supply Corporation, introduced in his water plant that although there is only one word difference from groundwater to surface water, it is a qualitative leap.

Now the people of Zhangye City have also drunk the surface water from Qilian Snow Water, which has been developed from scratch, and the water quality is completely qualified and meets 106 water quality requirements.
[Explanation] Ding Hui said frankly that the water source construction project has a total investment of 398 million yuan, covers an area of 1072 mu, and took 530 days to complete. Birds are often seen flying over the water surface, so compared to groundwater, the water at this source has the advantages of less pollution and good water quality, and the design concept of a smart water plant is also used.

The construction project of the backup water source in the urban area of Ganzhou District was designed and constructed based on the concept of a smart water plant from the beginning. It adopts automatic design and is closely integrated with the dynamic water use information of the entire urban pipe network, and finally realizes the current joint production and joint adjustment of the two water plants, which greatly improves the city's water supply quality and guarantees the city's water supply pressure and flow. , To meet the needs of urban water supply users in various regions.
[Explanation] It is understood that the local third groundwater plant with a daily water supply capacity of 80,000 tons can no longer meet the needs of current economic and social development, resulting in huge water supply pressure. The completion and use also completely eliminated this development "bottleneck" and realized a historic breakthrough in drinking surface water from scratch.
