Sewer/Storm Drainage Rates

Properties inside city limits will be assessed an annual fee for sewage treatment and maintenance of city sewer lines. There are a small number of residences in the city limits that are also within a sanitation district. Since the city does not maintain these sewer mains, the sewage treatment fee from the city is lower. Additional charges may be assessed by the sanitation district for maintenance.

Properties inside city limits

Storm drainage rates are applicable only to properties located inside the city limits.

Properties outside city limits

Littleton provides wastewater treatment services to most city residents and to residents of eight sanitation districts in the southwest metropolitan area. Properties within these districts are assessed sewer treatment charges only. Sewer lines are maintained by the sanitation district in which the property is located, and that district may bill for maintenance or may have a property tax assessment.

How the money is spent

Sewage, or wastewater, is a combination of liquid and solid wastes from residences, commercial buildings, industrial plants and institutions. The city is responsible for regulating the collection of wastewaters, as well as its treatment. The sewer service charge is used to pay for the costs associated with this responsibility. Sewer service charges are used for:

Sewer service charge Percentage used
Replacement Cost 36%
Maintenance Cost 8%
Operating Cost 56%
TOTAL 100%

Sewer/storm drainage facts

  • The city maintains 128 miles of sanitary sewer lines.
  • South Platte Water Renew (SPWR) wastewater treatment plant, co-owned by the cities of Littleton and Englewood, is the third largest in Colorado.
  • The plant opened in 1977; prior to that, both cities operated small, inefficient and costly wastewater treatment facilities.
  • The largest size sewer pipe is 66" in diameter; big enough for a person to walk through.
  • The oldest operating sewer line, located in downtown Littleton, is more than 100 years old.
  • The SPWRP processes more than 22 million gallons of sewage every day.
  • There are eight sewer districts in the Littleton service area that contribute flows to the sewer plant. The Englewood service area has 12 districts. The service area for both cities exceeds 75 square miles.
  • Sewage sludge, or bio-solids, is collected at the plant and taken to a farm in eastern Colorado. This material is used as a soil amendment. The cities own more than 10,000 acres of farmland for recycling bio-solids.
