Sewer Service Questions

The City and County of Denver is only responsible for main public sewers. For information about your private tap/serviceline, we recommend you to hire a licensed plumbing company that provides such services.
Immediately phone 303-446-3400 and report the problem. A maintenance crew will be dispatched to your location as quickly as possible If the problem is found in the city sewer line, Wastewater personnel will service the line and correct the problem. If cleanup is necessary due to a problem in the city line, we will arrange to have it completed in an efficient manner. If the problem is found to be your private line rather than the city sewer line, we will inform you as soon as possible. It would then be your responsibility to contact a plumber to service your line and repair any damage which may have occurred.
Believe it or not, a dry drain can lead to this condition. Drain pipes are constructed to hold a small amount of water. This retained water creates a seal to keep odors from coming up into your house. This water seal can evaporate, thus allowing foul odors to come into your house. To remedy this situation, you should pour a little water down your drain each month.
Do NOT flush disposable diapers and baby wipes as they will clog your sewer line. In addition, never pour grease or gummy substances down garbage disposals, toilets, or floor drains. Flammable liquids, i.e. oil, gasoline, paint thinner, etc., should never be poured into your sewer line as they can cause a fire hazard or create a harmful coating on your sewer pipe. Never flush plastic tampon containers, pencils, pins, hypodermic needles, broken glass or other foreign objects that can lodge in your sanitary line and prevent consistent flow.

The combination of moisture, warmth, and nutrients that exist in all sewer lines (private and city) provides an excellent environment for roots to grow. Roots from trees, plants, and shrubbery are first attracted to the exterior of the sewer line and will penetrate the smallest crack or pin hole. This growth can eventually clog sewer lines.
It is extremely unlikely that sewer water will get into your drinking water. Incoming drinking water lines are designed to be pressurized and are installed above outgoing sewer lines. With this design, any sewer leakage would run downward and away from the line providing you with drinking water.

If you have a question about your water service, call the Denver Water Department at 303-893-2444.
