Typical Problems to Report
  • Sewage smell or visible liquid sewage runoff in a neighborhood with septic systems. First, contact the health agency for your town from the list above. They will send an inspector/sanitarian to investigate. Follow up with a second call 7 days after the initial one to learn the status of the problem. Make sure there is a written report that describes the results of the investigation. If the owner of the septic system does not take corrective action, the health agency will need the initial report in order to take enforcement action.
  • Sewage smell or runoff from a multi-unit condomimium complex, strip mall or office building. Contact the CT Department of Environmental Protection and the local health agency at the numbers above. Make the follow-up call described as above to both agencies after 7 days.
  • Odorous discharge from a manhole cover, storm drain, or sewage odor in a neighborhood connected to sewage lines. Contact the municipal Water Pollution Control Authority or the Public Works Department.

Laws and Regulations

Request a copy of the state Public Health Code from your local or regional Health Department or District. The code describes the procedures for abating septic system pollution and for enforcement action where necessary.

The local Health Department of District regulates all septic systems with a wastewater flow under 5,000 gallons per day. The Connecticut Department of Public Health will step in to regulate if requested by the local health agency or if the local agency is unable to resolve a septic problem.
