How to Install Your Septic Tank
1. Dig and Prepare the Base
Excavate a hole six to twelve inches wider than your tank. Make sure the top of the tank sits no more than twenty four inches below the ground surface. Spread six to twelve inches of clean gravel or coarse sand to create a level and well draining foundation.
2. Set and Level the Tank
Lower the tank into the excavation. Rock it gently from side to side until it sits perfectly level. Keep the inlet side slightly higher than the outlet side so wastewater flows correctly.
3. Backfill While Adding Water
As you backfill around the tank with gravel or loose soil, pour clean water into the tank at the same rate. This approach helps the tank settle smoothly without shifting or floating.
4. Install Risers and Cover
Attach any required risers so the access lids rest at ground level. Cover with six inches of topsoil, then reseed or plant grass to blend with your yard.
5. Connect Piping and Baffles
Use approved fittings to attach inlet and outlet pipes. Install baffles to keep solids and scum from entering the drain field.
6. Final Check and Permits
Confirm the tank remains level, seals are tight, and pipe connections are secure. Contact your local health department to arrange any required inspections before use.
Estimating Installation Cost
To plan your budget, keep the following factors in mind:
-
- Tank capacity and type can affect material cost.
- Soil conditions such as rocky or clay soils may require extra preparation.
- Local labor rates vary by region and the experience of septic installation companies.
- Permit and inspection fees from your health authority.
Most homeowners spend between three thousand and seven thousand dollars on a standard system. To get precise pricing, request detailed quotes from several septic tank installers and compare what is included.
Care and Maintenance of Your Septic Tank
-
-
Regular Inspections
Inspect plumbing fixtures, pipes, and tank access covers for leaks or damage. Walk the drain field looking for wet spots or extra lush grass, which can indicate a backup. -
Monitor Sludge Levels
Use a sludge judge or probe to check solids. Arrange for pumping when scum comes within six inches of the outlet or solids within twelve inches of the bottom. Always replace and seal the cover securely after testing. -
Pumping Schedule
Plan to pump your tank every three to five years based on household size and tank volume. After pumping, refill the tank halfway with water to keep it stable. -
Effluent Filter Care
Clean or replace the filter once per year to protect the drain field from clogs.
