Water distribution network and maintenance

The Town of Hampstead is responsible for maintaining and managing the local potable water distribution network throughout its territory. This includes municipal water mains, valves, hydrants and associated infrastructure.

The supply and quality of drinking water are the responsibility of the Ville de Montréal, which provides water through the Atwater filtration plant and the major aqueduct network, including the main line located beneath Ellerdale.

This division of responsibilities ensures effective service management while maintaining compliance with provincial drinking water standards.

Discoloured Water

Discoloured water may occur following work on the distribution network.

In such cases, residents are advised to let cold water run for several minutes until it clears, in accordance with municipal notices.

For urgent or prolonged issues, residents are encouraged to contact Public Security.

The Town of Hampstead is responsible for:

Maintaining public water mains
Emergency interventions (water main breaks, major leaks)

Issuing notices to residents when required

Property Owner Responsibilities

Property owners are responsible for:

Interior plumbing
The private water service line (depending on the configuration)
