City is testing fire hydrants throughout Guelph

Mandatory testing taking place
fire hydrant testing

The City is tests over 2,700 fire hydrants every year across Guelph.

What to expect

• There's no disruption to water service during testing
• No chemicals are used
• Residents living near a tested hydrant may see discoloured water for a short period; drinking small amounts of discoloured water is unlikely to cause health issues, however, we recommend waiting until water runs clear before drinking it.

Why we test fire hydrants
Fire hydrant testing helps protect our community by ensuring hydrants are in proper working order when needed for fire suppression.
