About the St. Marys Sanitary Collection System

The Town of St. Marys owns and operates the sanitary collection system that is designed to safely and efficiently collect wastewater from homes, businesses, and institutions throughout the community. This system, comprised of approximately 55 km of underground pipes and pumping stations, ensures that wastewater is transported away from residential and commercial areas, helping to maintain a clean, healthy environment for all residents.

The collection system is routinely monitored and maintained to meet or exceed provincial standards, with a focus on reducing inflow and infiltration, preventing blockages, and minimizing the risk of overflows. Residents can help by keeping fats, oils, and greases out of drains and by properly disposing of non-biodegradable items.

St. Marys Wastewater Treatment Plant

All wastewater collected through the sanitary system is conveyed to the St. Marys Wastewater Treatment Plant. Here, treatment processes remove contaminants, protecting local waterways and the natural environment. The treated effluent meets stringent environmental regulations before being safely discharged. The treatment plant is monitored by certified operators and utilizes various wastewater technologies to maximize efficiency and environmental protection. The facility is committed to continuous improvement and innovation, ensuring that the needs of St. Marys are met now and into the future.

Annual Reports

Transparency and accountability are important to us. Each year, the Town of St. Marys prepares detailed annual reports that outline the performance of the sanitary collection system and treatment plant, compliance with environmental regulations, and any major projects or improvements. These reports are available to the public and offer insights into how we are working to maintain and enhance our community’s vital wastewater infrastructure.
