Perc Testing and Soil Evaluation

Title 5, the Massachusetts law that regulates septic systems, requires that a perc test and a thorough soil evaluation be performed prior to designing a new septic system or repairing an existing one.

Our state of the art Geographic Information System (GIS) helps us to better assess your site prior to arriving. This system utilizes the latest aerial photos overlaid with detailed soils maps, wetland areas, topography, drainage patterns and protected resource areas, which allows us to more accurately decide where and when to perc.

Under certain conditions, to determine the perc rate when the soil is too wet to perc, the State of Massachusetts allows soil to be tested in a soil lab.  This policy is permitted for repairs only, and can be a useful tool for completing projects year round. We provide these laboratory services with our sister company, TerraFilter.

Experience counts, and Green Hill Engineering has performed over 1,500 perc tests and soil evaluations. This depth of knowledge and expertise ensures the best possible results for our clients.
