Project introduction: The water area is 150000m2, the depth is 1.5-2.0m. Thisartificial lake was build basing on the original ponds. Features of the water:turbid, green, having indication of algae bloom; having oil-film on watersurface, benthic algae floating, transparency less than 0.3m, reaching thestandard of surface water Class Ⅴ; lacking of underwater ecological system, lacking of underwateraquatic plants, having low self-purification capability.
Purification effects: The water is clear, and the transparency reaches more than 1.5m.The underwater landscape is beautiful. Main eutrophic indexes (dissolvedoxygen, ammonia nitrogen, total nitrogen, total phosphorus, potassiumpermanganate index, etc.) reach or better than the standard of surface water(GB3838-2002) Class Ⅱ-Ⅲ. Long-term effects is achieved. Cost for exchanging water isreduced after restoration. Additionally, along the lake, the houses, whoseprice have risen by about 12% and trading volume goes straight up.
Project anecdotes: The scene of Li Lake is picturesque, so multiple activities, suchas photography competition, eco-tourism etc., have been hold there. Theecological planning of Li Lake international community’s water system becomesnot only the demonstration project of the whole landscape water system but alsoone of the features of the community building marketing. The Li LakeInternational Community was titled “The livable demonstration buildings inChina of 2015”, because of its unique glamour.
Project completion date: August 2014.
