Edmundston and Saint-Basile Districts
The network extracts water from the groundwater layer supplied by the Blanchette Brook and charged by a system of lakes supplied by a pumping station with a 1200 U.S. gallons a minute capacity that draws water from the Iroquois River. These waters are naturally filtered by a gravel bed above the groundwater layer where six fifty feet (on average) wells are situated, each of which produces approximately 450 U.S. gallons of water per minute. This natural filtering environment removes color, particles in suspension, algae, vegetation and most bacteria and viruses.
The raw water is pumped to a treatment plant where liquid chlorine is injected under pressure in two water mains that transports the drinking water to the City. The municipality’s water treatment process is rigorously controlled to guarantee high quality water.
Verret District
This aqueduct network extracts water from a well along the Trois-Milles River. The raw water is treated by a hypo-chlorination unit and then transported in the District aqueduct network.
Saint-Jacques District
This aqueduct network is supplied by the “Rivière-à-la-Truite”. Raw water enters a sedimentation tank where it stays for a few days and then is transported to the filtration gallery where it is treated by a hypo-chlorination unit and transported in the aqueduct network of the District.
Quality assurance!
Every year, the municipality performs approximately 850 quality analysis at the Edmundston Regional Hospital and the Provincial Department of Environment laboratories. These analyses compare our water’s characteristics to more than fifty parameters which allow us to collect information about the physical, organic, inorganic and especially microbiological properties of the raw water, the treated water and the distributed water. The data from this control program confirms the excellent quality of the water that circulates in the aqueducts of our municipality.
Supplying and Distributing Water
Edmundston’s water supply networks are composed of a vast pipe assembly, pumping stations, reservoirs, valves, fire hydrants, aqueduct services and meters. It is one of the most complex aqueduct networks in New Brunswick. It receives water from three water purification installations and distributes clear drinking water to consumers. Five pumping stations and ten reservoirs along the distribution network allow the accumulation and the pumping of water with sufficient pressure to meet the various needs. Thanks to these installations, the Municipality is able to ensure normal and extraordinary consumption requests. The ten water reservoirs have a storage capacity of 30 065 750 liters of water allowing the City to insure good protection against fires.
