Source & supply
South Fredericton Aquifer (Wilmot Park / St. Anne's Point and Queen Square wellfields)
About 10–11 production wells in Wilmot Park / Queen Square feed two treatment plants, then ~400+ km of watermains, booster stations, and reservoirs serving most households and businesses in the city. Wellfield Protected Area Designation Order (Clean Water Act) regulates land use in Zones A–C around the wells.
City reports the aquifer is recharged mainly by the Saint John River (about 60–70%), with lesser contributions from the water table and bedrock — groundwater that is naturally filtered through sand and gravel.
Treatment
