Questions

Frequently Asked Questions

How often should my septic tank be pumped?

For most households, every 3 to 5 years, though it depends on tank size and how many people use the system. If you're not sure when yours was last serviced, we can inspect it and set you up on a schedule.

What is a BioMicrobics FAST system?

FAST is an advanced on-site wastewater treatment system (an ETPS) that installs in the tank to handle challenging soils or failing systems. As a certified provider, we install, service, and monitor them to DEQ standards.

Do you handle the DEQ inspections and permits?

Yes. Septic work in Idaho comes with Department of Environmental Quality requirements. We handle the inspections, effluent monitoring, and maintenance so your system stays compliant.

How does the free inspection offer work?

Book any septic pumping through Nov 30 and we'll include a visual inspection of your system at no extra charge - honest findings explained before winter sets in. Just mention this offer when you call.

What areas do you serve?

We serve Twin Falls and the surrounding Magic Valley, including Jerome, Kimberly, Filer, Buhl, Hansen, Wendell, Gooding, Rupert, Burley, and Hagerman.
