Who We Are

​The Metro Wastewater Reclamation District is the wastewater treatment authority for much of metropolitan Denver and parts of northern Colorado. We are committed to protecting the environment and providing for the community's future needs.
  • We serve about 2 million people who live and work within our 715-square mile service area, which includes Denver, Arvada, Aurora, Brighton, Lakewood, Thornton, and Westminster.
  • We collect about 130 million gallons of wastewater per day from neighborhood sewer lines and remove more than 95 percent of the pollutants before discharging it into the South Platte River.
  • We make wastewater suitable for agriculture, aquatic life, recreation, and water supply.
Our mission is to protect the region’s health and environment by cleaning water and recovering resources. ​​​​​
