2026 Septic System Replacements

The purpose of this project is to decommission three failing residential sewage disposal systems and replace them with new septic systems to prevent potential risk to groundwater and human health at tenanted properties within Rouge National Urban Park. The site locations are 230 Uxbridge-Pickering Townline, 135 Concession Rd. 9, and 21 Beare Road. Additional sites could be added to this project if emergent situations occur throughout the year and a corresponding BIA amendment will be produced. The failing septic systems will be pumped and backfilled and pits approximately 2.0 metres deep will be excavated to contain the new septic beds and pump tanks. Trenches will be excavated between the dwellings, septic tanks, pump tanks and leaching beds to install underground pipe systems. The area for the leaching beds will be excavated to various depths and surface areas, depending on the site requirements as suggested by relevant engineers. Some vegetation clearing is expected and there is potential for tree cutting to facilitate the work due to the size of heavy equipment required for excavation and septic component installation. During the work, temporary sediment fence barriers will be installed at necessary sites and topsoil will be stockpiled locally and 30m away from water features or with suitable erosion and sediment control. The new septic systems will comply with the 2012 Ontario Building Code and will have expected minimum service lives of 25 years provided trees, shrubs, and vegetation with deep roots are controlled.
