If SIPH or DEQ says a standard trench will not fit your soil or groundwater, the next step is a system with a published Idaho design — not a few extra lines dug on a Saturday. Alternative systems cost more to install, and many of them cost something every year after that. We would rather say that on the first call than after the field fails.
Irrigation-season water, coarse soils, and shallow basalt are the usual reasons a Blackfoot-area lot — including rural parcels near Aberdeen — lands here. The permit path is on the permits page. The work itself is a design and installation or a replacement.
Extended treatment units
These are manufactured units that treat wastewater further before it reaches a drainfield. They show up where soils are shallow or very coarse, groundwater is high, or extra treatment is required. They need electricity. Shutting them off for the winter is not a savings — it creates more maintenance, not less.
Idaho expects at least one operation-and-maintenance visit a year, plus monitoring so effluent stays inside the limits (including nitrogen limits when those apply). An annual report is due to the health district by July 31. The property owner is on the hook if that report never arrives. Before anyone pumps one of these tanks, the service provider for the unit should be in the conversation. They are not a plain 1,000-gallon concrete box.
If you already have one, call us for the pump-out and alarm, pump, and filter work. Tell us the brand on the permit so we know whether the visit is a standard pump or needs the unit’s service provider on site.
Mounds, pressure distribution, and other complex work
Pressure distribution, sand mounds, proprietary treatment systems, and similar designs generally require a complex installer. A basic installer license is not a discount version of that. If your lot is headed this direction, we scope it as a permitted install, not a longer leach line.
Large systems
At about 2,500 gallons per day or more — some shops, clusters of homes, small commercial sites — Idaho treats the system as a large soil absorption system. Expect an engineer, DEQ review, and an annual operation report. Call with the daily flow in mind so we do not price a house system for a building that is not a house.
Homeowner installs
Idaho allows a homeowner to install a standard system on their own property with no hired help after the permit is issued. That exception does not cover complex systems, and it does not cover hiring an unlicensed friend with a backhoe. If you want us on the machine, say so at the start and we will match the job to the license it needs.
