Septic service in Dewey-Humboldt

Septic help for the rural town in the Agua Fria River valley, on the road between Prescott Valley and Mayer.

Dewey-Humboldt is one of Yavapai County's younger towns. It incorporated on December 20, 2004, joining the old communities of Dewey and Humboldt, and had 4,326 residents at the 2020 census. It sits about 15 miles east of Prescott at around 4,800 feet. Humboldt's lone smelter smokestack on Main Street is a reminder of the mining and smelting days.

Big lots, on-site systems

The town describes itself as rural and says residential lots are typically larger than half an acre, with most areas at 1.6 acres or more. Homes spread across lots like that are typically served by their own septic systems rather than a sewer main, often alongside a private well. If you're not sure what you have, Yavapai County can look up septic records by parcel number.

Older systems on older homes

Some properties here have homes and systems that go back decades, and some have had a manufactured home replaced or a casita added since the system was permitted. If the house has more bedrooms or more people than when the system went in, the tank and field may be undersized. A pump-out with a look at the baffles, and a check of the county's permit file, is a good first step.

Common jobs

  • Transfer inspections when properties sell
  • Pumping and baffle repairs on older tanks
  • System upgrades for additions and replaced homes
  • New systems on vacant acreage
