•Detailed site evaluation required for new systems
•Required setback distances:
–Septic tank: 100 feet
–Disposal field: 100-300 feet
•Volume and location requirements
The State of Maine
regulations are published by the department of human services (DHS) and for
this study regulations adopted on June 1, 2000 were used.
Systems in use beforeregulations were in place, which are
functioning properly are grandfather and not required to be updated.
The site evaluation
includes assessment of soil suitability, setback requirements, soil profile
and conditions, proposed system location, slope, surface runoff and existing
subsurface groundwater drains.
For shoreland residences
the proper setback from a major water course (the lake) for a septic tank is
100ft and 100-300ft for a disposal field.
There is a volume
requirement for septic tanks based on the size of the residence it is
servicing.For disposal fields
an important deciding factor is the way water will flow through the soil.
