Choosing the right on-site wastewater treatment system depends on several factors, including soil conditions, groundwater levels, and site-specific regulations.
The EPA Site Suitability Assessment is the first step in determining which system will work best for your location.
This assessment evaluates the soil’s ability to absorb and treat wastewater, ensuring compliance with environmental standards.
If you’re unsure which system suits your project, our team can help guide you based on your site assessment results.
The type of percolation area required depends on the results of a percolation test, which measures how quickly water drains through the soil.
This test helps determine whether you need a conventional percolation area, a soil polishing filter, or a more advanced tertiary treatment system.
To ensure compliance and optimal performance, we recommend speaking with a wastewater specialist who can review your site conditions and advise on the best solution for your project.
In most cases, installing a septic tank requires planning permission, especially for new builds, upgrades, or sites in environmentally sensitive areas.
Local authorities will typically request an EPA Site Suitability Assessment and percolation test results to confirm compliance with EPA and building regulations.
If you’re unsure about the requirements for your project, our team can provide guidance.
