Littleton is a split-utility city: water comes from Denver Water, while sewer is a City of Littleton service with treatment at South Platte Renew. A sewer line replacement here covers the private pipe from your house to the city's sewer, and many lines date from the city's 1950s and 1960s growth. Call the number on this page to be connected with a local plumber in Littleton.

Who handles the sewer in Littleton?
Most city residents are billed for sewer by the City of Littleton, and wastewater is treated at South Platte Renew, which Littleton and Englewood own together. Residents of connecting communities are billed by their local sanitation district instead, so the provider can change from one address to the next; the city's Special District Look Up Map shows which applies. For a sewer problem that may be in the city's system, call 303-795-3959 during normal hours or 303-794-1551 after hours. Denver Water handles the water side, not the sewer.
Why do so many Littleton sewer lines wear out?
Littleton grew quickly in the 1950s and 1960s, and many homes from that era were connected with clay or cast iron pipe. After sixty-plus years, clay joints have often let roots in and cast iron has often rusted thin, so the damage is spread along the line instead of sitting in one place. That is the typical case where replacement beats a series of spot repairs. Newer homes have plastic pipe, which usually fails only where soil has settled or a later project damaged it.
What permit does a replacement need, and from whom?
The City of Littleton requires a permit to install, alter, repair or replace any plumbing system within city jurisdiction. The Permit Center is at 303-795-3751 or [email protected], and homeowners doing their own single-discipline work sign a Homeowner Affidavit. A Littleton mailing address does not always mean city jurisdiction: the ZIP codes also cover unincorporated communities such as Columbine, Ken Caryl and Highlands Ranch. Addresses outside city limits get permits from Arapahoe, Jefferson or Douglas County, and the city's District Map Tool will tell you which.
A local note
Older Littleton lots often have mature trees, which is good for shade and hard on clay sewer pipe. If a camera shows roots at many joints, pipe bursting can replace the line along the same path with less disruption to the yard than a full trench, provided the old line hasn't sagged. Asking for a copy of the inspection video gives you something to compare if you get a second opinion.
