Why Do I Need a Perc Test?
You need a perc test to determine if you can install a drain tile, infiltration basin, or septic system and leach field. A failed perc test means you either cannot use the land for that purpose or you’ll need to redig the land, creating more drainage. Without drainage, you’ll end up with standing sewage and water.
Cost of Soil Test for Septic Systems
Using a perc test to determine a ground’s suitability for septic systems and leach fields costs $750 to $1,300 on average. Large parcels of land might need multiple assessments in multiple areas to find a good place to install one.
That price doesn’t include septic installation costs of $3,000 to $10,000.
A failed perc test means building a raised system or no system at all.
Most land purchases in undeveloped rural areas require this report before getting a permit.
About 25% of all U.S. homes use septic systems.
Perc Tests for Septic Repairs or Replacement
Perc tests for septic repairs cost the same for new installs, or $750 to $1,300 on average. That doesn’t include septic system repair costs of $500 to $2,500. You’ll need an assessment for any septic or leach field repairs or replacements. If it fails or shows slow drainage, you’ll likely need to replace all or portions of the field.
Infiltration Basin Land Perc Test Costs
Perc tests for infiltration basins cost the same as for any other purpose or between $150 and $3,000. For extremely large areas, you might spend over $3,000, but typically that’s for agricultural or commercial purposes.
An infiltration basin, also known as a recharge basin or percolation pond, manages stormwater runoff. It prevents erosion and localized flooding. At its most basic, it’s a low spot created for rainwater to collect. It then drains slowly into the soil before it floods landscaping, homes, or roads.
