East Cherry Creek Valley Water and Sanitation District (ECCV) sustains a community of approximately 55,000 residents in portions of Centennial and unincorporated Arapahoe County by providing safe, reliable water and sewer services. The District is customer focused but recognizes the importance of regional partnerships such as ECCV's Northern Project where renewable water from the South Platte is treated at the District's state-of-the-art Northern Water Treatment Plant and transported 31 miles to ECCV customers. The Arapahoe County Water and Wastewater Authority (ACWWA) is also a partner in the project, receiving renewable water through the facilities. In 2014, ECCV transferred ownership of an existing east-west waterline to the South Metro WISE Authority (SMWA) and Denver Water to facilitate delivery of renewable water supplies to members of the SMWA while also maintaining capacity to provide water to ECCV's customers. Through this involvement ECCV continues to work toward providing its community with a fully sustainable water supply.
