Sedalia Water and Sanitation District provides water to properties inside its boundaries but, despite its name, doesn't provide sewer service, and no other sewer provider was verified. Sedalia is unincorporated, so Douglas County issues plumbing permits under its own inspection program. Call the number on this page to be connected with a local plumber in Sedalia.

Who provides water and sewer in Sedalia?
Sedalia Water and Sanitation District, formed in 1958, took over a water system originally installed by the railroad and serves properties within its boundaries. Despite the name, the district says it doesn't provide sanitary sewer service, and our research didn't find another sewer provider. That means a Sedalia business may rely on a private onsite wastewater system, and the line from the building to that system is private plumbing. Properties in the wider 80135 ZIP outside the district aren't served by it, so arrangements there vary. District questions go to 303-688-2506.
Which office handles permits?
Sedalia is an unincorporated community in northern Douglas County, so the Douglas County Building Division issues building permits, weekdays from 8 a.m. to 5 p.m. The Colorado Division of Professions and Occupations lists Douglas County as running its own county-wide plumbing inspection program, so plumbing is permitted and inspected by the county rather than the state. Ask the county whether a water heater swap, fixture change or line repair needs a permit before work starts.
What kind of commercial work comes up here?
Sedalia is tiny, with a post office dating to 1872, and sits on U.S. 85 about eight miles northwest of Castle Rock. Commercial plumbing here usually means a few businesses along the highway and rural or agricultural buildings nearby. Typical calls involve water heaters, restroom fixtures, frozen lines in outbuildings and slow drains. For buildings on an onsite system, keeping grease, wipes and harsh cleaners out of the drains protects both the building drain and the system it feeds. The fact sheet didn't describe a backflow program for the district or confirm a gas utility, so ask the district about backflow assemblies and check your gas bill for the emergency number. Writing down where the building's water shutoff and drain cleanouts are, and posting it for staff, saves time when something goes wrong.
A short local note
For a gas smell, get everyone out of the building first, then call 911 and your gas utility or propane supplier from a safe distance. Before winter, drain outdoor and outbuilding lines and keep heat on wherever there's plumbing.
