Source water protection for business, builders, developers

Does your business affect Guelph’s water supply?

  • Handling, storing, and application of agricultural source materials, pesticides, commercial fertilizers, road salts
  • Handling and storing fuels, organic solvents, dense non-aqueous phase liquids (DNAPLs)
  • Operating a septic system
  • Handling and/or storing waste including hazardous waste, polychlorinated biphenyls (PCBs) or liquid industrial waste
  • Livestock grazing
  • Applying and/or storing manure, fertilizer or pesticides

Planning and building permit applications

All planning and building permit applications for properties in wellhead protection areas or intake protection zones must meet the requirements of Guelph-specific policies in the Grand River Source Protection Plan.

If you are planning to use, handle or store materials that could pose a threat to Guelph’s water supply, the City may require you to modify your application. For example, you may need to move the planned location of certain activities, reduce the volume of chemicals stored, or use an alternate chemical. The City may also require a Risk Management Plan before as part of your application.

Local source water protection policies apply to all proposed activities on a property, regardless of its current zoning. For example, a proposed chemical storage facility is subject to the requirements of the Source Protection Plan, even if the property is currently zoned to permit such a facility.

The City cannot approve a planning or building permit application if it does not comply with the policies in the Source Water Protection Plan.

Risk Management Plans

If you use, handle, or store materials that could pose a threat to Guelph’s water supply you may need a Risk Management Plan.

Your plan must demonstrate how you will to mitigate drinking water threats using best management practices. In cases where spill response and other best management practices are already in place, a Risk Management Plan can be simple and straightforward. Plans can be updated as operations change over time. Risk Management Plans are legally binding agreements negotiated between you and the City of Guelph.

Please complete the Source Water Review form to determine if you need a Risk Management Plan.
