Most may not realize it, but many properties are serviced by an individual on-site sewage disposal system, commonly known as a septic system. A modern, well-maintained septic system should serve a property for many years, but just because they are underground does not mean they should be forgotten. Septic systems are designed to properly treat and dispose of domestic waste. They generally consist of a septic tank and a disposal field, but may also include a pump, pump tank, pre-treatment system, alarm system, or in the case of older systems, none of the above. At a minimum, your septic system’s tank should be pumped approximately every three years to increase its life span. Detailed information on how to maintain your septic system may be found in A Homeowner’s Guide to Septic Systems or contact the Health Department.
