In 1961 the Colorado State Legislature formed the Metropolitan Wastewater BOARD MEMBERS Reclamation District (Metro) to provide wastewater collection and treatment to Kathy Jensen Ward Rd. member municipalities and special connectors in the front range area. A hearing Paula Corbin 52nd Ave. was held in January 1967 and an Order and Decree was approved to permit William Karlin sewer service within the boundaries of the District. At that time the District Phil Wathier New Sewer Construction became a member municipality to Metro. As a member municipality, the District Michael Ellis collects wastewater from homes and businesses and delivers it to Metro’s collection system where it heads to their treatment plant. The District is charged MANAGER for the treatment of the wastewater based on the quantity of wastewater and the Rick Jeschke, PE amount of contaminants. The District’s original collection system was less than a mile long, however, today the District maintains over 65 miles of sewer mains. 1958 - 2008
