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 1.8 million people across a 715-square mile service area including 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, industrial use, water supply and recreation.
Our mission is to provide wastewater transmission and treatment services to Metro District ratepayers in an efficient, cost-effective manner while continuing to meet all statutory and regulatory requirements. ​​​​​
