Welcome to the Southeast Metro Stormwater Authority (Authority) web site. The Authority was formed in September 2006 via an Intergovernmental Agreement between the City of Centennial, Arapahoe County, the Arapahoe County Water and Wastewater Authority, East Cherry Creek Valley Water and Sanitation District, and Inverness Water and Sanitation District. The Authority is responsible for Stormwater Services within its service area.
