Guiyang is taking significant steps to ensure a reliable water supply with the Wangjia Well project, which has an innovative design tailored to the city's challenging karst terrain. 

The facility utilizes elevated platforms to support its treatment structures, including flotation tanks, filtration units, and clear water reservoirs. According to Xu Rui, a project representative, these are ingeniously stacked and supported by 455 main piles and a framework of beams and columns. 

The design significantly reduces the plant's land footprint to just 0.15 square meters, half that of traditional facilities. It also enables a gravity-fed water flow system, which minimizes energy consumption.

The project, launched in 2021 to enhance the resilience of the city's water supply, comprises a 20-kilometer water transmission pipeline and a treatment plant with a daily capacity of 200,000 cubic meters. 

The facility employs advanced water treatment techniques, including coagulation stirring, high-speed ion flotation, and V-shaped filtration. These processes are seamlessly integrated into an automated control system, ensuring efficient operation and reduced energy usage. 

With primary construction and equipment installation now complete, the plant is undergoing final testing and adjustments. It is expected to begin operations by the end of the year, marking a significant milestone in Guiyang's pursuit of a sustainable and resilient water supply. 

It will serve approximately 840,000 residents in Guiyang's Nanming, Yunyan, and Wudang districts and the Guizhou Shuanglong Airport Economic Zone.
