Prescott Septic InstallAreas we serve in Yavapai County
Updated
Whether a property needs a septic system depends on whether sewer reaches it. Here is what we know about each area.
Dewey-Humboldt
Dewey-Humboldt has no municipal wastewater system. (Source: Arizona university engineering study of an onsite wastewater design for a Dewey-Humboldt home, checked October 2026.) Homes there rely on their own onsite systems.
Chino Valley
Chino Valley town code only requires lots under one acre to be served by a town-approved water and sewage disposal system, and current land listings state that a well and alternative septic system will be needed. (Source: Town of Chino Valley town code and current Chino Valley land listings, checked October 2026.) Sewer is limited, and much of the acreage relies on septic.
Prescott
Some Prescott properties, particularly older and outlying ones, use septic rather than city sewer. If you are not sure which your property uses, say so in your request.
Unincorporated Yavapai County
Yavapai County runs its own delegated septic permitting program, with separate tracks for conventional and alternative systems. (Source: Yavapai County, Septic System Construction page, checked October 2026.)
A note on Prescott Valley
Under Prescott Valley town code, a development receiving a town water allocation must participate in the town sanitary sewer system, or be able to within five years. (Source: Town of Prescott Valley Town Code section 51.037(B), checked October 2026.) As a result, most newer Prescott Valley subdivision homes are on sewer. Some older or outlying properties may still be on septic, and you are welcome to ask.
