Our Sanitary Sewer System

The Municipality of Arran-Elderslie operates a sanitary sewer system designed to safely collect and transport wastewater from homes and businesses to treatment facilities. This system plays a vital role in protecting public health and the environment by ensuring that wastewater is properly managed and treated before being returned to natural waterways.

Our responsibilities include:

Maintaining sewer mains, manholes, and pumping stations
Monitoring system performance and addressing blockages or backups
Complying with provincial regulations for wastewater management
Investing in upgrades to improve efficiency and reliability

Residents can help by avoiding flushing wipes, fats, oils, and grease, which can cause costly clogs and damage to the system.
