A fire hydrant is a connection point to the municipal water system that allows firefighters to access water for fighting fires. Hydrants are strategically located throughout developed areas to ensure adequate water coverage, typically within specific distances based on fire protection standards. The distinctive colours often indicate water flow capacity—high-flow hydrants may be one colour, lower-flow hydrants another. Municipal water departments maintain hydrants, ensuring they function properly through regular testing and maintenance including winterization in cold climates. Hydrants must remain accessible—parking in front of hydrants is prohibited, and snow clearing keeps them visible. Development approvals require adequate hydrant coverage, and insurance costs may be higher for properties outside hydrant-served areas. Private fire hydrants on large properties are the owner's responsibility to maintain. Fire hydrants represent essential infrastructure connecting fire response capability to water supply.
