Many properties within our Health District are
not located in areas where public sewers are available. These
properties are connected to on-site subsurface sewage disposal
systems, also called septic systems. The purpose of a septic system
is to dispose of the wastewater generated in a house (or building)
without contaminating the ground water or surface water.
system consists of four parts:
- Sewer line: connects the homes plumbing to the septic tank.
- Septic Tank: allows for the retention and partial digestion of
the solids by bacterial action (primary treatment). A properly
functioning septic tank retains solids and will reduce pollutant
levels by producing an effluent of fairly uniform quality.
Septic tanks installed since 1991 consists of two compartments.
Since 2000, septic tanks are required to have an effluent
filter, which help protect the leach fields.
- Distribution system: directs the flow from the septic tank to
the leaching fields.
- Leaching fields: A drainage system that applies sewage
effluent into the surrounding soils. There are many different
types: trenches, galleries, drywells, or plastic units.
Whatever kind of septic system you have, it is very important to:
- Have your septic tank serviced (pumped out) every three to
- Do not allow vehicles and heavy equipment to be driven over
the septic system (unless the system was designed for this)
- If your septic tank came with an outlet (effluent) filter,
have this cleaned out routinely (Depends on the quality of waste that you send to your septic tank)

- It has become
customary for either buyers and/or sellers of real estate to employ
home inspectors, installers, private consultants or professional
engineers to inspect and report on the condition of the existing
sewage disposal system. To aid in standardizing this process, the
state has recommended a standard sewage disposal inspection form
that has been endorsed by the Connecticut Sewage Disposal
Association, the Connecticut Realtors Association, the home
inspection industry as well as the Connecticut Environmental Health
Association. To download a copy of this form, please go to:
