"The 'Wangshan' Cangnan Eastern Water Treatment Plant, designed by POA Architecture, is currently under orderly construction. The project commenced design in 2023, recently achieved its main structure topping-out, and is expected to be fully completed by the end of 2025."

Cangnan Eastern Water Treatment Plant, located in Qianku Town, Cangnan County, has a Phase I capacity of 120,000 m³/day. The project includes the construction of conventional water purification facilities, advanced treatment systems, sludge treatment facilities, soft ground improvement works, auxiliary plant structures, and other supporting infrastructure. The site covers a total area of 47,573 square meters, with above-ground building space spanning 13,080 square meters.

"Cangnan is a city of mountains and waters, so its water treatment plant should embody this landscape. Guided by the design philosophy of 'Looking to the Mountains' (Wang Shan), POA Architecture seeks to seamlessly integrate natural and cultural elements into this industrial facility. By blending Eastern aesthetic sensibilities with modern functionality, the project aims to create an ecological and intelligent architectural model that reflects the harmony of 'half landscape, half city.'"

which is now under construction.

"Currently, the main structure of the Cangnan Eastern Water Treatment Plant has been topped out, with ongoing installation of internal equipment and pipeline systems. Upon completion, the plant will significantly enhance water supply capacity for Cangnan’s eastern region, establishing a resilient 'multi-source backup' water distribution network. It will deliver eco-friendly, clean drinking water to key areas including Mazhan Town, Yanpu Town, Xiaguan Town, and Chixi Town."

"The project adopts a traditional courtyard spatial layout, where the central garden organically integrates with surrounding functional zones. A water feature is introduced from the south, creating a distinctive waterscape. The elegant and fluid skyline design harmonizes with adjacent residential areas, embodying the design philosophy of 'organic symbiosis between people, architecture, and the environment.'"

"As a municipal infrastructure project with a total floor area of 13,080 square meters, this facility serves multiple critical functions. While its primary mission is to deliver eco-friendly, clean drinking water to residents, it also plays a vital role in stimulating local economic growth, creating employment opportunities, and generating government tax revenue."



"Anticipating the building’s composite value during the design phase, flexible spaces were strategically reserved on both sides of the front plant complex’s comprehensive building—laying the groundwork for future functional expansion. This forward-looking approach elevates the project beyond the single-purpose role of traditional water treatment plants."


"We look forward to the early completion and commissioning of this project, which will provide eco-friendly, clean drinking water for the people of Cangnan."
