Septic Regulations in Connecticut

About 30% of the population of Connecticut own private on-site sewage systems. To prevent health hazards and contaminations, there are guidelines and rules formulated by the state and local health departments for the proper installation and maintenance of these private septic tanks.

Connecticut Regulation of Septic Tank Systems

The Connecticut Department of Public Health is the authority in charge of administering subsurface sewage disposal systems. They have various regulations and technical standards in place in accordance with the Public Health Code (PHC) and the Technical Standards.

Licensure Requirements for Septic System Contractors

The Department of Public Health regularly conducts training courses and examinations on the subject of subsurface sewage disposal based on the PHC. Only those who undergo this training and pass the examinations successfully are deemed qualified to carry out inspections and approve plans to construct sewage systems.

Installing a New Septic System in Connecticut

Any construction of a new septic system, alteration of an existing system, or repair of a subsurface sewage disposal system requires an approval and a discharge permit issued by the local director of health. Homeowners have to apply for permission and submit the form to the local director of health along with the plan of the lot.

A soil test with a satisfactory outcome is mandatory before applying for permission to construct. Authorized personnel approved by the Commissioner of Public Health then need to inspect and approve the plans for construction. After construction, the system needs to be inspected, approved and then will be finally given the permit to discharge or operate.
