Septic Systems

The City of Peterborough is now responsible for receiving and reviewing new septic applications. 

This page provides important information regarding the requirements and process for obtaining a permit to repair, expand, or install a new septic system.

Application Requirements

To apply for a septic system building permit, you will need to submit the following:

• A completed Application Form (including Schedule 2: Septic Installer form)
• A site plan showing all existing and proposed structures, septic components, and setbacks from lot lines, wells, and water sources
• Any additional applicable forms

Please submit your completed application package to residentialpermits@peterborough.ca.

Submission Guidelines

Septic permit applications must be submitted either prior to or alongside permit applications for new dwellings, additions/renovations, or replacements. This ensures that the septic system approval process aligns with your building permit application.
