Tour a Denver Water treatment plant

Although water from our mountain reservoirs comes from rain and snowmelt, it must be tested and treated to ensure that safe, potable water is delivered to our customers.

Request to visit a drinking water treatment plant to learn the five-steps of potable water treatment or learn about the expanding recycled water system at the Denver Water Recycling Plant. Recycled water — treated to just below potable standards — has helped meet the city’s needs for irrigating parks, golf courses and school grounds, replenishing lakes and serving industrial users.

Treatment plant tours

  • Denver Water Recycling Plant (near 58th Avenue and York Street)
  • Marston Treatment Plant (near Sheridan Boulevard and Quincy Avenue)
  • Moffat Treatment Plant (near West 20th Avenue and Kipling Street)

Note: Because of security precautions and staffing limitations, tours of reservoirs and storage facilities are not available at this time.
