Septic services in Maricopa and Pinal counties
We match homeowners with independent licensed septic contractors for the work below. If you are not sure which one you need, that is normal: on most Arizona properties the answer comes out of a soil evaluation rather than out of a catalogue.
Replacing or installing a system
The big-ticket work, and where the ground does most of the pricing. Which of these you need is usually settled by a soil evaluation, not by preference.
- Septic System Replacement. Replacing a failed or failing system on a property that already has one.
- New Septic System Installation. A first system on raw or newly built land with no sewer connection available.
- Alternative and Engineered Systems. What poor percolation, caliche, shallow bedrock, slope or a high water table push a property onto.
- Drain Field and Leach Field Replacement. When the tank is sound but the disposal field has stopped absorbing.
Finding out where you stand
The two jobs that come before the quote. Both produce a document somebody else is going to read: a county reviewer, or a buyer.
- Perc Test and Soil Evaluation. The measurement that decides whether a conventional system is even an option on your lot.
- Septic Inspection for Property Transfer. Arizona's mandatory pre-sale inspection, its six-month window, and who is qualified to perform it.
Two things that shape every one of these jobs
First, the ground. Caliche, poor percolation, shallow bedrock, steep slope and a high water table are what move a property from a conventional system to an alternative or engineered one, and that is the largest single swing in any Arizona septic quote.
Second, the county. Maricopa County Environmental Services and Pinal County Environmental Health run separate permit programs, so the forms, the fees and the review steps differ depending on which side of the line the property sits on.
Which county permits your system
Arizona delegates on-site wastewater permitting to counties, and the two in this service area run separate programs. Find your county before you start any paperwork.
Maricopa County
Permitting and inspections run through Maricopa County Environmental Services. Covers the unsewered Phoenix metro fringe: Buckeye, Cave Creek, New River, Rio Verde, the Surprise fringe and the Queen Creek edges.

Pinal County
Permitting and inspections run through Pinal County Environmental Health. Covers Casa Grande, Apache Junction, San Tan Valley and the city of Maricopa, which despite the name is in Pinal County, not Maricopa County.
