Septic Installation in Boerne, TX
Outside the city’s sewer service, Boerne is septic country. We install systems for acreage homes, custom builds and commercial properties throughout the Boerne area.
Building on Acreage Around Boerne
Boerne has kept much of its small-town character while the land around it has filled in with homes on larger tracts. Along I-10, SH 46 and the county roads that branch off them, many of those properties sit beyond the reach of city sewer and depend on an on-site septic system.
The ground is classic Hill Country: thin topsoil, limestone close to the surface, creek bottoms and slopes that change across a single lot. Owners often build on rises for the view and want to keep the oaks around the house. A good septic layout respects all of that while meeting the setbacks the design requires.

Septic Systems We Install in Boerne
On most Boerne-area lots, the shallow soil points toward an aerobic treatment system. The treated water is then distributed by spray heads or, more often for homeowners who want an uncluttered yard, by a drip field buried just below the surface. Where a site has enough suitable soil, a conventional system may be permitted, and it is usually the simpler system to own. We also handle replacements for older homes whose original systems have failed.
Engineer Referral for Evaluation and Design
Every septic system in Texas starts with a site and soil evaluation by a licensed site evaluator and a design prepared by a registered sanitarian or professional engineer. We work closely with an engineer we have a great relationship with and will put you in contact with them through our septic design and engineer referral service. The engineer handles the evaluation and design and guides you through the process. Questions about tank placement, equipment access or how the field will fit around a future pool can be settled before the design is submitted, not after. If you already have a design, we can price and install from it. We then install the system under our TCEQ OSSF installer license OS0031132, coordinate the county inspections and finish the site.
Septic Permits in Kendall County
Boerne is the county seat of Kendall County. Septic permits for unincorporated Kendall County are handled through the county’s development office at 400 E. Blanco Road in Boerne. The county reviews the design, issues the permit and inspects the installation before the system goes into service. Aerobic systems also require a maintenance contract and a recorded affidavit. If your property is inside the city limits, check with the City of Boerne first about sewer availability. Our Kendall County page covers the wider county.
Building a new home? Bring us in while the house plans are still flexible. Driveway, house pad, pool and septic field all need room, and early coordination avoids costly changes. See new construction septic.
Commercial and Site Work
We also install commercial septic systems for properties around Boerne that are not served by sewer, and we take on the excavation and site work that often goes with a new build, including clearing, pads and driveways.
Family Owned Since 1995
Peter Varhol founded the company in 1995. His sons, Dennis and Mike Varhol, run it today and are lifelong Hill Country residents. When you call about a Boerne project, you will talk with Dennis directly, and we will come out to see the property ourselves.
