Two significant water projects, the Pingshan River Main Stream Comprehensive Regulation and Water Quality Improvement Project, and the Runoff Regulation, Storage, and Transfer Project in Niucheng village of Tiegang Reservoir in Nanshan district, have been honored with the 2021-22 China Water Engineering Quality Award, also known as the Dayu Award. This award is the highest of its kind in China.

The Pingshan River project is recognized for its innovative use of three-dimensional precise management technology. This technology, grounded in progressive risk identification, is used for flood control and drainage within the basin. The project also leveraged a new technique characterized by "precise pollution interception, decentralized regulation and storage, distributed treatment, and local reuse," thereby enhancing water pollution control and facilitating ecological restoration within the basin system.

Following the project's implementation, the water environment of the Pingshan River has seen steady improvement. Its annual average water quality has achieved the Class III national standard for surface water for four consecutive years. This project has brought about a fundamental improvement in the river's water ecology. In addition to the Dayu Award, it has also received the National Quality Engineering Award and the China Civil Engineering Zhan Tianyou Award.

The second project involved local river channel reconstruction, the creation of a water intake collection system, a regulation and storage system, a water transfer and transport system, and the construction of ecological water facilities and service facilities.

The Tiegang Reservoir is crucial for meeting the water demands of Shenzhen's western area. The project is capable of intercepting rainwater in Niucheng village based on different precipitation levels and transferring it to the output reservoir.

Thanks to this project, over 700,000 cubic meters of water have been replenished to the Lishui River and Dasha River in Shenzhen. Additionally, a total of 45,000 square meters of green area has been created. This project was also awarded the First Prize for the High-quality Water Conservancy Project of Guangdong Province.
