Water and Sewer Utility

DEPARTMENT OVERVIEW:  Water and Sewer Department Overview

Water Distribution

The Province of Prince Edward Island is totally dependent on groundwater for its source of drinking water.  As groundwater flows through an aquifer it is naturally filtered. The natural filtering process and the long residence time underground means that groundwater is usually free from disease-causing organisms and requires very little treatment. However, for the purpose of public health, the water is disinfected (chlorinated) to ensure a high level of water quality to the points of delivery and consumption.

The Water and Sewer Utility is responsible for the maintenance and repair of the Town’s water systems including water pumping stations to provide residents and business with an adequate supply of high quality drinking water. The water distribution system includes 4 water pumping stations (8 wells), 1 reservoir, 1 booster station 115 hydrants, mains (45 km.) and services.
