The cranberry industry is the pillar industry of the Wareham Region. Cranberry cultivation has a long history in this area. However, the cranberry cultivation, which almost becomes a cultural symbol, has brought much more pain points to the local ecology and economics. Based on the tail water treatment of cranberry industry, this project tries to solve the water pollution, repair the river channels and introduce new industries through establishing ecological tail water handling system, so as to alleviate the local situation of heavy dependence on the cranberry industry.
