"Dianchi lake basin ... is not only the biggest drinking water...

"Dianchi lake basin ... is not only the biggest drinking water source for the city .. is so important to the local economy that without it, Kunming could not have developed to its present economic level."

"The area of Dianchi Lake is shrinking annually and water pollution problems in the lake are increasingly serious. In summer and autumn, 84% of the lake surface is covered with algae .. poor quality of tap water has evoked very strong public response in the surrounding urban areas."

"The overall objective of this project is to suggest management measures and suitable technical and engineering measures for the control of eutrophication and for the water reclamation in Dianchi Lake and to construct the related demonstration project."

It's recommendations are exactly what IETS - IMH will be doing, ie, "controlling non-point pollution sources in Dianchi Lake".
