Drinking Water Source Protection Logo


Owned by the Township of Alfred-Plantagenet and operated by the Ontario Clean Water Agency (OCWA), the Lefaivre Water Treatment Plant draws its water from the Ottawa River. The intake is located in Lefaivre, north of the Lefaivre Water Treatment Plant, approximately 90 m off shore at a depth of 15 m. The system serves a population of approximately 4,500 residents and also includes the municipalities of Alfred, Plantagenet and St. Isidore. This drinking water system is one of 13 systems that draw water from surface water in the form of rivers or lakes in the Raisin-South Nation Source Protection Region.

Vulnerability Scoring

The vulnerability score is a representative measure of the drinking water source's susceptibility to contamination due to the nearby physical landscape (ratio of land to water in the area, land cover, soil type, and hydrological and hydrogeological conditions in the area) and the physical conditions at the intake (depth of the intake, distance from land, past drinking water issues).

Higher values indicate a higher level of concern for contamination. Intake Protection Zones (IPZs) are the areas where policies may apply to protect drinking water sources. IPZ-1 is the zone immediately near the intake. IPZ-2 is an area based on the response time required to react to a reported spill.
