Septic System Installation in Louisa & Hanover County
New construction at Lake Anna, replacements on clay soil, conventional or engineered alternative systems — permitted, installed, and documented properly the first time.
What a new system costs
| System type | Typical installed range | Where it fits |
|---|---|---|
| Conventional gravity | $15,000 – $25,000 | Good soils, adequate lot size |
| Sand filter | $12,000 – $25,000 | Moderate soil limits |
| Drip dispersal | $15,000 – $30,000 | Clay soils, sloped sites |
| Treatment unit (ATU) systems | $15,000 – $55,000 | Small/waterfront lots, poor soils |
| AOSS engineered design (add) | $1,500 – $4,500 | All alternative systems |
Buying an AOSS? Every alternative system in Virginia legally requires an annual visit by a licensed operator for the life of the system. We bundle the first year of O&M service with every AOSS install — and handle the state reporting.
Start with the soil, not the brochure
Every honest install quote begins with a soil evaluation and VDH permitting through your health district. We coordinate all of it — evaluation, design, permit, installation, and final inspection.
