Sewer to the tap, water from Denver Water
Plumber Littleton CO
Littleton's city code says the property owner maintains the sewer service line from the public sewer to the building, including the tap, and restores the right of way. Drinking water is Denver Water's, not the city's.
The sewer sentence
Section 7-5-24, as published in the city code viewer, makes the owner responsible for that service line including the tap, and for returning the street to city standards. If the building sits too low for gravity, the owner installs and maintains a lifting facility. That is an ejector, not a sump. The city's right-of-way page says a sewer-specific construction permit is no longer issued and a right-of-way permit is used when work occupies the street, sidewalk, or alley. Acceptable repair pipe named there includes Schedule 40 PVC or SDR 35, with bedding called out. Those are Littleton's specs, not Aurora's. A mailing address that says Littleton can still be outside the city. Confirm the parcel.
The water sentence
The city's water-supply page says potable water is provided by Denver Water and that Littleton Public Works does not provide it. Report water breaks to Denver Water, 303-893-2444 in the hours they publish and 303-628-6801 after hours. Lead-line help, if any, is Denver Water's program, not an automatic free dig. A private water line repair is what you buy when the program says no.
Questions to settle first
Who fixes a blocked sewer lateral in Littleton?
The owner, under the code section that includes the line from the public sewer to the building and the tap, plus street restoration. The city keeps the public sewer. A right-of-way permit covers work in the street. Aurora's version is similar in spirit and still the wrong citation.
Who do I call for a water-main break?
Denver Water, using the numbers on Littleton's water page: 303-893-2444 or 303-628-6801 after hours. The city says it does not provide potable water. Those numbers are Denver Water's, not this guide. Ask them to write that limit into the quote before you compare it with another company.
The basement is too low to drain. Whose pump is it?
Yours. The code says the owner installs and maintains the lift when gravity cannot reach the public sewer. That is a sewer ejector. It is not the city's main, and it is not a groundwater sump. Ask them to write that limit into the quote before you compare it with another company.
