In Littleton, water comes from Denver Water, but sewer is a City of Littleton service for most residents, with treatment at South Platte Renew. The drain pipes in the house and the line to the city's main are private, so a plumber is the first call for a clog. Call the number on this page to be connected with a local plumber in Littleton.

Who do I call about a sewer backup in Littleton?
For a clog in your plumbing, a plumber. For a problem in the public sewer, most city residents call the City of Littleton, at 303-795-3959 during normal hours or 303-794-1551 after hours. Littleton's sewer is a city service, separate from Denver Water, and the wastewater is treated at South Platte Renew, the plant Littleton owns jointly with Englewood. Residents in connecting communities are billed by their own sanitation district, and the city offers a Special District Look Up Map. Littleton ZIP codes also reach into unincorporated areas like Columbine and Ken Caryl, which are served by other districts entirely.
Why do Littleton drains clog more as homes age?
Littleton grew rapidly in the 1950s and 1960s, and much of the city is detached single-family homes from that boom. Houses of that era often have cast iron drains inside and clay or concrete sewer pipe outside. Cast iron narrows as scale and rust build on its walls, and clay joints let roots in, especially where older shade trees grow near the line. The result is a main line that slows gradually, then backs up during a heavy laundry day or a holiday weekend. A camera inspection after clearing shows whether roots or a broken section are the cause.
Is it worth fixing the pipe instead of cleaning it again?
If the line clogs once every few years, routine cleaning is usually enough. If it backs up every few months, the footage from a camera inspection helps decide whether a spot repair, a liner or a full replacement makes more sense. Factors include how much pipe is damaged, what sits above it, and how deep it runs. City permits are required to repair or replace any plumbing system in Littleton, and homeowners doing their own single-discipline work sign a Homeowner Affidavit. The Building and Development Permit Center handles both.
One local note
Because Littleton splits water and sewer between two different providers, don't call Denver Water about a sewer backup. Your sewer bill, from the city or your sanitation district, tells you who handles the public main at your address. Keep that bill handy when you call a plumber, too.
