What is considered an undersized septic tank?
The current Public Health Code requires a 1,000 gallon tank for a 2 or 3 bedroom house; a 1250 gallon tank for 4 bedrooms; and a 1500 gallon tank for 5 bedrooms. Houses constructed in the 1950s and 1960s generally have 750 gallon tanks for a 2 bedroom house and 900 gallon tanks for 3 bedroom house – most of these are single compartment tanks. The proposed upgrade standards require a two compartment septic tank as these provide better separation and treatment than single compartment tanks.
