The City of Littleton says all of its residents are served by Denver Water, so homes inside city limits don't run private well pumps. Littleton ZIP codes also cover unincorporated areas such as Columbine, Ken Caryl and Highlands Ranch, which have other providers. Call the number on this page to be connected with a local plumber in Littleton.

Who supplies my water if I live in Littleton?
Inside city limits, Denver Water does. The city's Public Works Department doesn't provide water itself. A Littleton mailing address doesn't always mean city limits, though: ZIP codes 80120 through 80123, 80127 and 80128 also cover unincorporated communities such as Columbine, Ken Caryl and Highlands Ranch, which are served by other districts. Either way, these are public systems. If your bill comes from Denver Water or a district, you have no well pump; a pressure problem lies in the plumbing, the service line or the utility's main.
What could cause low pressure in an older Littleton home?
Littleton is an established suburb with a historic Main Street along the South Platte, and it grew fast in the 1950s and 60s. Homes from that era can have galvanized supply pipe that narrows with corrosion, gate valves that no longer open fully and regulators past their prime. A plumber can test pressure at a hose bib, then work inward to the regulator, main valve and fixtures to find where flow is lost. If the whole street is affected, Denver Water is the first call: 303-893-2444 during business hours or 303-628-6801 after hours.
Do I need a permit, and from whom?
The City of Littleton requires permits to install, alter, repair or replace any plumbing, gas, mechanical or electrical system within its jurisdiction. Homeowners doing single-discipline work themselves complete a Homeowner Affidavit. The Permit Center is at 303-795-3751. If your address has a Littleton mailing address but sits outside city limits, permits go to the county, which may be Arapahoe, Jefferson or Douglas, and the city's District Map Tool can tell you which jurisdiction you're in.
A local note
Water and sewer are split here: Denver Water supplies the water, while sewer is a City of Littleton service, with wastewater treated at South Platte Renew, which Littleton and Englewood own together. For an after-hours sewer emergency, the city's line is 303-794-1551.
When you call, say whether the property is inside city limits and which bill you receive. That tells the plumber which utility and which permit office apply before any work starts, which avoids delays on a repair that needs a permit.
