CSCEC has taken on the project of Nanhu Lake water quality improvement(ecological water rehydration), an important part of the lake's ecological environment restoration program. Building a virtuous cyclic water system, the project is set to improve living space and elevate people's happiness.

In accordance with local conditions, the project team purified the lake water by controlling pollutants from the source. Moreover, the adoption of water purification facilities and ecological restoration technology made a forest of submerged plants possible underwater. The project implemented the ecological restoration to generate the self-purification and self-repair of Nanhu Lake.

At present, the project is near completion. The enchanting summer scenery of Nanhu Lake is attracting more and more people.
