Smart eco-park to help residents breathe easier

Lei Peng, an engineer from State-owned China Railway No 4 Engineering Group Co Ltd, is somewhat uneasy at times while building an ecological park that is only some 600 meters from the sea in East China's Shandong province.

Besides bordering the Yellow Sea in the east, the Fenghe Ecological Sports Park — covering 19.5 hectares in the West Coast New Area of Qingdao — is only 60 meters away from the Fenghe River (Wind River) in the south.

"Besides paramount attention to water bodies, our most pressing task is that this project has two layers — the bottom layer being a burial sewage treatment plant while the top layer a sports park," said Lei, head of the engineering section of CREC4's project department for the park.
