River bottom
Mohave Valley, Fort Mohave, Golden Shores, Topock
Sand and silt laid down by the Colorado, with groundwater close below. Where the water table rides high, the county may call for an alternative system instead of a standard drain field.

Local knowledge
Three kinds of ground under the Tri-State.
A septic system is only as good as the ground it drains into. Along the river it’s sand and a high water table; on the terraces, gravel and caliche; up toward Kingman, rocky high desert.
Terraces & washes
Bullhead City, Lake Havasu City
Old river terraces of gravel and cobble, cut by dry washes and often cemented by caliche. Digging can stop at a hardpan, and a wash can run a flash flood in monsoon season.
High desert
Kingman, Golden Valley
Higher ground away from the river, with Kingman about 3,300 feet up. More homes on private wells, rocky alluvial fans, and winter nights cold enough to freeze an exposed pipe.
Before you call
Three emergencies, three first steps.
Sewage backing up?
Stop using water, keep people and pets out of the area, and call. Sewage is a health hazard. Never open a septic tank or lean into one: the gases can kill in moments.
No water from the well?
Check the well pump’s breaker. If it trips again, leave it off and call. Never open the pressure switch or control box: they carry 240 volts.
Smell gas?
Leave the building now, without touching switches, and call the gas utility or 911 from outside. Then call us for the repair.

Straight answers
Septic questions, answered.
Who issues septic permits in Mohave County, Arizona?
Mohave County Development Services issues septic permits for most of the county, under authority delegated by the Arizona Department of Environmental Quality (ADEQ). It reviews applications and plans, issues construction and discharge authorizations, inspects new systems and handles transfers to new owners.
Does Arizona require a septic inspection when a house is sold?
Yes. Under ADEQ’s rule (A.A.C. R18-9-A316), the seller must have the septic system inspected by a qualified inspector within six months before the property transfers, and give the buyer the inspection report before closing.
How often should a septic tank be pumped?
Most household tanks need pumping every three to five years, and the EPA recommends an inspection at least every three years. The real interval depends on tank size, how many people live there and how much water goes down the drain.
What is caliche, and why does it matter for septic systems?
Caliche is a layer of soil cemented by calcium carbonate, common across the Arizona desert. It can be as hard as concrete and lets water through slowly, if at all.
There’s no water from my well. What should I check?
Check the breaker for the well pump. If it has tripped, reset it once; if it trips again, leave it off and call. Something is wrong with the pump, the wiring or the controls.
How do I check a contractor’s license in Arizona?
Use the Arizona Registrar of Contractors (ROC) contractor search at roc.az.gov. Enter the six-digit license number or the business name, and check that the status is Active and the classification fits the work.
