Surface Water Sources

The watershed basin of the Gatineau River contains thirteen municipal networks of drinking water distribution serving a little more than 60% of the population. Nearly 88% of these people live in the City of Gatineau which draws its water from the Ottawa River rather then the Gatineau River.

Groundwater Sources

Other municipal drinking water networks use ground water and there are only five filtration stations as most of the residents have wells.

In the Outaouais region, more that 5,300 wells have been drilled and used as part of the Minister of the Environment's hydrogeological information system.

Little data exist on the groundwater in the watershed of the Gatineau River. Yet, in this territory, groundwater supplies a large portion of the population served by a municipal system.
