Septic Systems

Within South Windsor, many homes rely on on-site sewage disposal systems to treat their waste water. These systems are typically comprised of a septic tank used in conjunction with a distribution system and leaching structure (s). The waste flows from the house to the septic tank, where the separation of solids and fats/oils/greases occurs. The solids accumulate in the bottom of the septic tank (and should be periodically pumped out) and the liquid is dispersed over a large area of soil through the leaching structures (galleries, drywells, trenches or proprietary products), where biological filtration takes place. Information about septic systems is available at the State of Connecticut Department of Public Health. The South Windsor Health Department is responsible for:

  • Permitting all activities related to the construction or repair of any subsurface sewage disposal system.
  • Investigating any complaints related to failing septic systems.
  • Reviewing and approving plans for septic systems.
  • Conducting soil evaluations and percolation tests to assure site suitability.
  • Retaining records for all new and repaired septic systems including as-built drawings.
  • Assuring that any construction activities, or change in use of the property, do not adversely impact the on-site septic system or reduce potential repair area.

Homeowners, or their representatives (contractors), who rely on subsurface sewage disposal are required to contact the South Windsor Health Department to obtain a permit if they are:

  • Altering or repairing any part of a subsurface sewage disposal system.
  • Constructing a new system served or to be served by an onsite septic system.
  • Planning to construct an addition, accessory structure (decks, etc.) or out-buildings.
  • Planning on increasing the number of bedrooms.
  • Planning to install a swimming pool.
  • Doing a lot line revision.

The South Windsor Health Department, in cooperation with the State Department of Consumer Protection, is responsible for ensuring that on-site water wells are installed and maintained in a sanitary manner.  The South Windsor Health Department is responsible for ensuring that proper separating distances are maintained between all sources of pollution, including septic systems, ground water drains, etc., and the well.  We also maintain records of well drilling permits, completion reports and well water test results.

While the Health Department does not conduct well water testing, this list of certified laboratories are available to test your well water.

CT DPH Recommends Testing Wells for Arsenic and Uranium.  These naturally occurring metals are found in groundwater in sporadic locations across the state and can lead to adverse health effects.
