Septic Installation & New Construction in Bozeman, MT
New systems and replacements designed, excavated, and installed from the ground up — including septic for new builds.
Overview
What makes our septic installation & new construction different
Installing a septic system is the most involved thing we do, and it's where being a licensed septic installer matters most. A new system has to match your household, your soil, and your lot — get the sizing or the drain-field layout wrong and you'll be calling us back in a few years for a repair that didn't have to happen. We size the tank and drain field to your actual use, not a one-size guess. Every new installation starts with the lot: soil conditions, slope, setback distances, and how much water your household puts through the system all drive the design. We handle the excavation, set the tank, lay out and build the drain field, connect everything to the house, and backfill — then we walk you through how the system works before we leave.
New construction brings its own set of decisions. When you're building a new home, the septic system has to be planned alongside the foundation, the well, the driveway, and the lot lines — setbacks and soil suitability can shape where the house even sits. We work with you and your builder early so the septic design fits the lot instead of fighting it, and we size the system for the home you're actually building, including future bedrooms or a shop that might tie in later. Getting septic in the plan from the start avoids the costly rework that comes from treating it as an afterthought.
New septic systems require a permit from the local health department, and we install to meet that permitting process. We handle the installation side and coordinate with what the county needs so your project keeps moving. We don't quote fees or timelines for the health department here — those depend on your lot and the current requirements — but we install to the standard they expect.
Some lots can't take a standard system. Steep slopes, poor soils, high groundwater, or a small lot may require an engineered septic design. When that's your situation, we don't hand you a phone number and disappear — we connect you with a qualified engineer and coordinate the design end-to-end so the installation moves forward without the runaround.

FAQ
Septic Installation & New Construction questions, answered
- Do I need a permit for a new septic system in Bozeman?
- Yes — new septic systems require a permit from the local health department. We install to meet that permitting process and coordinate with what the county requires.
- What happens if my lot needs an engineered septic design?
- If your lot has steep slopes, poor soils, or high groundwater, we connect you with a qualified engineer and coordinate the engineered design end-to-end. You stay in one place with us through design and install.
- How do you size the tank and drain field?
- We size to your household and soil, not a default. The number of people, bedrooms, and water use, plus the soil's perk, drive the tank size and drain-field length.
- Can you replace an old system or only install new ones?
- Both. We install full replacements for failed or end-of-life systems as well as new systems on raw ground. A replacement usually means pulling the old tank and rebuilding the field.
- Do you handle the excavation too?
- Yes. We run the excavation, set the tank, build the drain field, and backfill — one crew from layout to finish, not a string of subcontractors.
