The Village of Casselman's municipal water intake is located in the South Nation River, off Drouin Street south of the railway bridge. The intake crib is located approximately in the middle of the river at a depth of 7 m below mean river level. Raw water is drawn through a mesh screen at the intake and flows into a raw water well which is located below the plant on the southeast bank of the river in the Village. Owned and operated by the Corporation of the Village of Casselman, the municipal water treatment system serves approximately 2,835 residents.
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.
The Casselman drinking water system has a third area of protection, IPZ-3, which is itself subdivided 3 times, and includes the total area contributing to the intake.
