Who provides water and sewer to a Dacono business?
For water, the City of Dacono has a Water Department under Public Works, with customer service at City Hall on Cherry Avenue, 303-833-2317, extension 121. Central Weld County Water District's service area also mentions the Tri-town area of Dacono, Firestone and Frederick, but we couldn't confirm whether it serves any Dacono addresses directly, so the water bill is the place to check. Sewer is St. Vrain Sanitation District, which serves Dacono, Firestone, Frederick and parts of Mead.
St. Vrain says the building sewer line belongs to the property, not the district. A backup that affects only your building is usually in that private line, and that's a job for a plumber. If you think the main is involved, the district keeps 24-hour staff for backups at 303-776-9570.
Does Dacono require yearly backflow tests?
Our research didn't find a published Dacono backflow program, so we can't say what testing schedule applies. Commercial buildings with irrigation, fire sprinklers or kitchen and process equipment usually have backflow assemblies,. Ask the city's Water Department what your account needs before an assembly is installed or replaced, and keep a copy of any test report with the building's maintenance records in case the city asks for it later.
Which office handles permits?
Dacono's Community Development department, which contracts building services to SAFEbuilt. Permit questions go to Community Development staff at 303-833-2317, and the city posts its building codes and permit information online. Ask before replacing a water heater, moving fixtures or repairing a service line, and leave time in the schedule for review and inspection so a tenant finish or equipment swap doesn't stall at the end. Dacono was settled in 1901 by coal miners and has grown along I-25 as one of the Carbon Valley Tri-Towns, so buildings range from older structures to new construction.
Gas note
Dacono's gas utility is Black Hills Energy. If anyone smells gas in a building, get everyone outside, then call 911 and Black Hills using the emergency number printed on the gas bill. Don't try to find the leak yourself, and don't flip switches or start equipment on the way out.
