Littleton and the surrounding postal area
The home page and its service pages cover the main Littleton leak questions. The area links add useful differences in water accounts, pipe responsibility and access. They are starting points for an inquiry, not a guarantee of service throughout a ZIP.
For 80120 and a property confirmed inside Littleton, use the main service pages. For addresses elsewhere, choose the community that fits your actual location. If the name is unclear, give us the street address rather than selecting a nearby place just because it shares a postal code.
Choose the community, then the problem
Highlands Ranch, Roxborough and Sterling Ranch have different water arrangements from the districts west and east of Littleton. The five area groups below each link to hidden-pipe, slab, underground-water and irrigation questions.
Some ZIPs cross municipal lines. A neighborhood grouping is useful navigation, while the exact property still determines the utility, building authority and permissions needed for work.
Postal codes are not all residential territories
The supplied list includes four P.O. Box ZIPs: 80160, 80161, 80162 and 80163. Give the address where the leak is occurring, rather than a mailing box.
80165 has conflicting public records: the city table labels it a discontinued building code while USPS routing material still lists it. USPS also lists 80166 in routing information, but that does not establish residential coverage. Neither code is treated here as a separate neighborhood or proof that an address is accepted.
What to have ready when you call
Use the street address, municipality if known, water-account provider and building type. Explain whether the concern is indoors, at floor level, along a buried supply route or around irrigation.
- Say whether water is actively spreading or whether the inquiry began with a bill or alert.
- Identify shared systems and the person who can approve access.
- Mention locked gates, tenants, finished surfaces or paving that may affect investigation.
- Confirm availability, inspection charges and the work included before arranging a visit.
All supplied postal codes
These are inquiry references, not district boundaries or confirmed service coverage. For 80165 and 80166, current postal records and the city list do not establish a residential area. Give the physical address rather than a PO Box or office ZIP.
