Overview
North Preston Wastewater Treatment Facility is a secondary treatment plant in Nova Scotia, Canada, serving 1,515 people. It discharges 680 cubic meters of treated wastewater daily and is located within 10 km of the coast.
The North Preston Wastewater Treatment Facility is located in North Preston, a community within the Halifax Regional Municipality, Nova Scotia, Canada. This secondary treatment plant serves a population of approximately 1,515 residents, reflecting its role in managing municipal wastewater for a small coastal community. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids, meeting the standards expected under Canadian federal and provincial regulations. For small communities like North Preston, secondary treatment is typical to protect local water quality. The plant's proximity to the coast (within 10 km) means its treated effluent ultimately reaches the Atlantic Ocean via local waterways. This coastal discharge requires careful management to minimize impacts on marine ecosystems, including shellfish habitats and migratory fish species. The facility contributes to protecting the health of the coastal waters in the Halifax region.
Environmental context
The plant's treated effluent flows into local streams and eventually into the Atlantic Ocean near the eastern shore of Nova Scotia. This coastal area supports diverse marine life, including lobster, groundfish, and seabird populations. The discharge must be managed to avoid nutrient enrichment and pathogen contamination that could affect shellfish harvesting areas and recreational waters. The watershed is part of the larger Atlantic Maritime ecozone, characterized by mixed forests and numerous small estuaries.
