Knowing What Lies Beneath
A good plan is developed from the ground, up. Knowledge of what lies beneath the surface of a site is key in determining the limitations of potential development. Any sub-surface domestic wastewater treatment requires soil testing to determine if the design is limited by any site specific parameters. This includes the design of sewage disposal systems and stormwater treatment facilities that are regulated by both state and local agencies.
MNTM provides a range of soils testing, including: percolation tests, deep test pits, and infiltration testing.
Percolation tests are completed by hand to avoid impacting the native material. These tests are used to determine the permeability of the in-situ soils. In conjunction with percolation tests, deep test pits are completed utilizing an MNTM-approved excavator to examine the different soil horizons. These tests are performed to determine the location of any existing bedrock, water table, or an impermeable layer that may impact the site design. A percolation test, in conjunction with a deep test pit, provides all the information our engineers need for sewage disposal system design.
