The Littleton/Englewood Wastewater Treatment Plant is the third largest Wastewater Treatment Plant (WWTP) in the state of Colorado. The plant receives sewage from the cities of Englewood and Littleton, as well as from 19 connector districts in the service areas of the cities. The plant is a large, advanced treatment plant required to exceed secondary treatment requirements and remove ammonia from wastewater. The design capacity is 50 million gallons per day (mgd) and is presently treating 23 mgd. To get more information on the evolution of the old Littleton and Englewood treatment plants into the combined Littleton/Englewood WWTP go to the Plant History page.
You are invited to take a cyber tour of the plant and visit each process area of the plant. In these areas you will find detailed descriptions and photos of the process and related equipment. Check out pictures and descriptions of the microscopic organisms (bugs) that make the treatment plant work.
The Littleton/Englewood WWTP strives to eliminate preventable odors and be a good neighbor in the community. Should a citizen detect an odor suspected of coming from the treatment, plant please call (303)-762-2619.
A facility this size cannot function properly and meet discharge permit limitations without a dedicated, professional staff. You can visit each division and check out awards the plant and staff have received. In the library, you will find articles and published papers written by our staff members.
You can find answers to questions about billing, potable water, storm drainage problems, and hazardous waste disposal in the Frequently Asked Questions page.
