Why Virginia Requires Routine Inspections for AOSS Systems
​
In the state of Virginia, Alternative Onsite Sewage Systems (AOSS) are required to be inspected and maintained on a regular schedule to ensure they continue operating safely and effectively. Unlike conventional septic systems, AOSS units use mechanical, electrical, and biological treatment components to clean wastewater before it enters the environment. Because of this added complexity, routine inspections are mandatory—not optional.
The Main Reasons Inspections Are Required:
1. To Protect Public Health
Failing AOSS systems can release partially treated wastewater into the ground, putting drinking water wells, nearby properties, and public waterways at risk. Inspections verify the system is treating wastewater properly and safely.
2. To Protect the Environment
Virginia strictly regulates AOSS systems because failing treatment units can contaminate streams, rivers, and groundwater. Routine inspections help prevent nutrient pollution and environmental damage.
3. To Prevent Costly Failures
Small issues like failing pumps, dirty filters, bad floats, or UV bulb failures can quickly escalate into major system breakdowns costing thousands of dollars. Inspections catch problems early, when repairs are still affordable.
4. To Meet Virginia Regulatory Requirements
VDH regulations require AOSS systems to be inspected at set intervals based on system type and permit conditions. Failure to maintain required inspections can result in violations, system shutdown orders, or problems during property sales.
5. To Protect Property Value & Real Estate Transactions
A non-compliant or failing AOSS system can delay or kill a home sale, trigger lender issues, and force emergency repairs. Staying current with inspections keeps your property protected and market-ready.
