Septic systems in Severn

Severn’s building department issues septic permits for a new or replacement system, a repair or upgrade, or any work that could affect an existing system. The application includes the building permit form, Schedules 1 and 2, a site plan, drawings and, where needed, approvals from other agencies such as the Ministry of Transportation or the Trent-Severn Waterway.

The Township’s servicing study lists Coldwater, Washago and Westshore as fully serviced for wastewater, so septic work there is limited to properties outside the serviced areas. It lists Ardtrea, Fesserton, Severn Falls and Marchmont as having no municipal service. The study is a couple of years old, so confirm your own property with the Township.

Severn’s Septic Inspection Program inspects every property in its mandatory areas (wellhead and intake protection zones) and discretionary areas (waterfront on Lake Couchiching, Lake St. George, Gloucester Pool and others) once every 5 years. The Township's program page lists which lakes are being inspected this year. If a system fails, the owner receives a report with a deadline, then a re-inspection.

Septic Installation, Replacement and Repair in Severn

Contractors in our network handle the installation side of septic work.

New Septic System Installation

A new system for a new build, a cottage, an addition, or a lot that has never had one. It starts with a permit and a designed system.

Septic System Replacement

When a tank, bed or whole system has reached the end of its life or no longer meets the Building Code, a replacement is designed and permitted.

Leaching Bed Repair

Soggy ground, odours over the bed, or sewage backing up after a pump-out often point to the leaching bed rather than the tank.

Pumping, cleaning and clogged drains

Looking for pumping, tank cleaning, or a clogged drain? Those are a different trade, and this site does not refer them. A local septic pumping company is the right call for a full tank or a blocked line. Come back if a pump-out shows the system itself has failed and needs repair or replacement.
