Septic Tank Installation Services
We coordinate the plumbing side of a new system and explain the full project. Some work, including design, permitting and installation of onsite sewage facilities, must be handled by authorized professionals. We tell you plainly who does what.
Conventional vs. Aerobic Systems
Conventional systems rely on soil absorption and suit good soils. Aerobic systems treat wastewater with air and are used where soil or space is limited. Aerobic systems cost more to maintain.
- Conventional: simpler, soil-dependent
- Aerobic: more treatment, more parts
- Maintenance contracts often required for aerobic
- Lot size and soil decide
Property and Soil Evaluation
A site evaluation looks at soil type, slope, setbacks from wells, water and property lines, and available space. The result drives system type and size.
System Design and Sizing
Size depends on bedrooms, expected water use and soil. Undersizing causes early failure, and oversizing wastes money.
Permits and Inspections
A new system generally requires a permit and inspection by the local authority before use. Skipping the process can block financing, resale and occupancy. We walk you through what to expect.
Septic System Replacement
Replacement follows a failed field, a collapsed tank or an expansion. We help you compare repair against replacement honestly.
Please donβt DIY this
- Do not install an unpermitted system.
- Do not choose an installer on price alone: verify authorization.
