The HVHD Sanitarians work to ensure that septic systems are located and installed according to the Connecticut Public Health Code. Properly installed and maintained septic systems reduce the risk of contaminating groundwater and reduce the health risk of exposure to untreated sewage to our residents.
Section 19-13-B100a of the Connecticut Public Health Code sets minimum standards for preserving subsurface sewage disposal areas on lots that are served by a septic system. The intent is to regulate activities that might increase the amount of sewage discharged to a septic system and construction activities that could reduce the area available for replacement of the septic system.
Under this regulation, any type of construction activity on a lot served by a septic system must be approved by HVHD prior to obtaining a permit from the local building official. This includes the construction of decks, sheds, swimming pools, barns and garages as well as adding a bedroom or other living spaces. In addition to the structures listed above, changes-of-use (i.e. residential houses being changed to a business facility) and home conversions must be reviewed and approved.Â
The determination of whether there is a suitable septic system area that meets the Health Code rests on analysis of soil data in our files (if it exists), neighboring wells, lakes and streams, inland-wetlands and other land features. In cases where there are no records on the existing septic system it may be necessary to conduct soil testing before a decision can be made. In many cases, a new septic system does not have to be installed unless there is a problem with the existing one. Simple applications can be processed in the office, others may involve a field inspection and site testing. Large additions or complicated site conditions may require evaluation by a Professional Engineer.
