What is an “Engineered” Septic System?
Because many areas don’t have suitable soils for typical septic systems or have other site constraints such as excessive slopes, or can not meet minimum setback requirements, a special design or alternative system may be required by the local Environmental Health Division. These systems are designed by a Civil or Structural Engineer, Registered Environmental Health Specialist, or an Engineering Geologist. Special design or alternative systems use new technology to improve treatment processes and require special care and maintenance. Some alternative systems use sand, peat, plastic or textile media instead of soil to promote wastewater treatment. Other systems might use aerators, aerobic treatment units or disinfection devices.
Float switches, pumps, and other electrical or mechanical components are often used in alternative systems. Special design and alternative systems are required be inspected and serviced at least on an annual basis by a Qualified Service Provider. Check with your local Environmental Health Division or Septic Pumper or Qualified Service Provider for more information.
