What an Alternative Septic System Needs
Alternative onsite sewage systems are essentially mini wastewater treatment plants buried in your yard — and they need more than the routine pump-out a conventional septic system gets. Virginia regulations require alternative onsite sewage systems (AOSS) to be operated and maintained by a licensed operator for the life of the system, with an inspection at least once every year. That's not a suggestion — it's a condition of your operating permit. Pump outs for AOSS is between 3-5 years.
Our team is licensed, manufacturer-trained, and equipped to handle the full scope of alternative septic work:
- Annual state inspections — full system inspection, sampling, and VDH reporting
- Control panels — diagnostics, replacement, alarm troubleshooting
- Floats and float switches — high-water, redundant, and pump-control floats
- Effluent filters — cleaning, replacement, and upgrades
- Alarms — audible and visual alarm repair and replacement
- D-boxes (distribution boxes) — inspection, leveling, and replacement
- Header lines — repair, replacement, and flow balancing
- Pump and tank components — pump replacement, tank pump-outs, and riser installation

Why Annual Inspections Matter (Beyond Compliance)
Most alternative systems give warning before they fail. An effluent filter slowly clogs. A pump starts pulling more amps. A float gets fouled. An annual inspection catches those issues while they cost a small amount to fix — not north of $10,000 after the drainfield is ruined. We document every visit, file the required VDH reports, and give you a written summary so you always know exactly what shape your system is in.
Honest Diagnostics on Complex Systems
Alternative septic systems are engineered, and they fail in engineered ways. A blinking control panel can mean a bad float, a fouled filter, a pump on its way out, or simply a tripped breaker — and the cost difference is significant. We diagnose before we quote, explain the actual problem in plain language, and give you options when more than one approach makes sense. No upselling on parts you don't need.

How often does an alternative septic system need to be inspected in Virginia?
