The Metro Wastewater Reclamation District is the wastewater treatment authority for most of metropolitan Denver. It was formed by the Colorado state legislature in 1961 to provide wastewater transmission and treatment services to its member municipalities and special connectors in compliance with federal, state and local laws. These municipalities and connectors, in turn, provide retail wastewater services to approximately 1.6 million people in a 615 square mile service area. MWRD collects and treats about 140 million gallons of wastewater per day. There are approximately 4,500 manholes and 232 miles of pipe in Metro's trunk line sewer system.

Environmental Coatings is a wholly owned subsidiary of JPCI Services and provides products and services for municipal water and wastewater system rehabilitation. JPCI has also provided consultation, specification, and troubleshooting services for many cities, companies and engineering firms.
