Tank Installation Information
Anti-buoyancy Information
Tank installations may require additional precautions, to insure tank submergence in high ground water areas. Evaluation must be provided after identifying site specific soil conditions, so check with your local County Inspector for more information.
Tanks should not be emptied by more than 50% during periods when groundwater is high and the soil conditions are poor. This recommendation is for cautionary purposes only, and may not be used as a substitute for physical buoyancy restraints.
Please see the downloads to the right for specific anti-buoyancy instructions covering each of the different sized tanks that we carry.
Septic Tank Excavation Instructions
Tanks manufactured with plastic risers and lids are also available. Finish height with risers should be at ground level. Backfill around and isolate tank before 24 hour water test.
