Three simple bands tell you everything you need to know before commissioning a perc test.
Likely buildable with a conventional septic system. Strong candidate for a formal perc test.
Likely buildable but may require an engineered septic system. Worth a formal test.
High likelihood of perc test failure. Buyer should investigate further before committing.
50x cheaper and 1000x faster than a traditional perc test.
