​​Water - Fire Hydrant Flow Test​>

City of Calgary testing on fire hydrants

We conduct various flow tests annually to identify potential problems and to make sure there is adequate water pressure and volume in the system.

Volume issues can be caused by closed valves and/or deterioration of aging pipes. The levels of residual and static pressure are often measured during the flow test and are good indicators to the conditions of the water system.
