Transport Pathway Notification

What is a Transport Pathway?

A Transport Pathway is a man-made feature on the landscape that increases the vulnerability of the raw water supply at the source of the municipal drinking water system.
Transport Pathways redirect the natural flow of water to surface water sources, or disturb the surface above an aquifer which increases the rate or quantity of flow to a groundwater source. In either case, a drinking water source may be impacted.

Examples of Transport Pathways

Affecting Surface Water Sources

  • Drainage Infrastructure including: storm sewer lines, discharge pipes, utility trenches, ditches, swales, tile drains, storm water ponds, or any other type of drain.

Affecting Groundwater Sources

  • Wells or boreholes, unused or abandoned wells, pits, quarries, construction activities involving deep excavations, and underground storm, sanitary or water distribution system infrastructure if within 3m of the top of the aquifer that supplies municipal source water.

Municipal Responsibility

Section 27 of Ontario Regulation 287/07 requires municipalities to notify the Source Protection Authority Chairperson, Source Protection Committee Chairperson, and the applicant if they become aware of a proposal that will create or modify a Transport Pathway in a Vulnerable Area.
