Septic systems
Septic System Installation
New septic tank and drain field installs, repairs and replacements, built to the approved design and scheduled for inspection with the right health department on the right side of the state line.
What we install
Tank, field, and everything between.
Out here, most property that is not inside a city sewer district is on septic: Apple Valley, Hildale, Colorado City, Cane Beds, most of Kane County and nearly every acreage parcel in between.
We install new systems for new builds, replace failed systems, and repair tanks, lines and drain fields. The design comes from a certified evaluator based on your soil test. We build exactly what got approved.

Local ground
Your soil decides your septic system.
The perc test tells the designer how fast your ground drains. Here is what usually shows up in Washington County and what it means for the install.
Caliche
Hardpan under the drain field slows drainage and can push the design toward a larger or shallower field. We dig through it cleanly so the field sits in the soil the design was based on.
Blue clay
Tight clay drains slowly, which can mean a bigger drain field or an alternative system. The evaluator flags it; we build exactly what gets approved.
Sandy red soil
Common around Apple Valley and Hildale and usually the easiest ground for a conventional system. Even then, trench walls need care so the field stays open.
Permits
Who permits your septic depends on which side of the line you are on.
We work in two states and four counties, and every one has its own process. Here is who you are actually dealing with.
Washington County, UT
Southwest Utah Public Health Department, Washington County office, (435) 986-2580. You need a soil evaluation by a certified evaluator, an approved design, a septic system application, installation to that design, and a final inspection before backfill.
Kane County, UT
Same health department, Kane County office, (435) 296-5477. Same sequence. Note that some parcels in Kane County also need Utah prairie dog habitat clearance from the Division of Wildlife Resources before anything gets dug.
Mohave County, AZ
Mohave County Development Services, Environmental Quality, (928) 757-0903. Arizona runs on a Notice of Intent to Discharge under a Type 4.02 general permit. A passing percolation test comes first, a well stays at least 100 feet away, and after construction you file for discharge authorization and a final inspection.
Coconino County, AZ
Coconino County Environmental Quality, (928) 679-8764, handles conventional and some alternative systems up to 3,000 gallons per day. Larger systems, and several specific communities including Page, go through ADEQ directly.
What we handle
The install and the inspection scheduling. We build to the approved design and we do not backfill until it has been looked at. We are not the system designer, and we will tell you plainly when you need one.
What comes first
The soil test. Everything downstream — the size of the field, the type of system and the price — comes from how fast your ground drains. Call us before you buy the lot, not after.

FAQ
Common questions
Do I need a septic system or can I connect to sewer?
Inside St. George, Hurricane, Washington, La Verkin and Kanab city limits you are usually on sewer. Apple Valley, Hildale, Colorado City, Cane Beds, most county parcels and most of Kane County are septic. If you are not sure, call us with the address.
How do I get a septic permit in Washington County, Utah?
Through the Southwest Utah Public Health Department, Washington County office at (435) 986-2580. You need a soil evaluation by a certified evaluator, an approved system design, an application, installation to that design, and a final inspection before backfill.
What about a septic permit in Arizona?
In Mohave County it runs through Mohave County Development Services Environmental Quality at (928) 757-0903, on a Notice of Intent to Discharge under a Type 4.02 general permit, and a passing perc test comes first. In Coconino County it is Coconino County Environmental Quality at (928) 679-8764 for conventional systems up to 3,000 gallons a day.
What is a perc test and do I need one?
It is a soil evaluation that measures how fast your ground drains, done by a certified evaluator. Yes, you need one, and it has to pass before a permit is issued in either state. It also determines how big your drain field has to be, which drives the price.
How long does a septic install take?
The dig and set is usually a matter of days. The timeline that actually matters is the soil test, design and permit ahead of it, and that is measured in weeks. Start early.
