Hollets Road Outfall Wastewater Treatment Plant, Marystown, Newfoundland and Labrador

Hollets Road Outfall is a municipal wastewater treatment plant located on Ville Marie Drive in Marystown, Newfoundland and Labrador, Canada. The plant serves a small population of 443 residents and operates under secondary treatment standards, reflecting its role in managing local domestic wastewater in this coastal community. As a secondary treatment facility, Hollets Road Outfall provides biological treatment to reduce organic matter and suspended solids, meeting typical Canadian federal and provincial wastewater regulations. The plant's discharge volume of 199.00 cubic meters per day is consistent with its small service population, and it operates under the oversight of Newfoundland and Labrador's Department of Environment and Climate Change. The plant discharges treated effluent into the local marine environment, given its proximity to the coast. The receiving waters ultimately flow into the Atlantic Ocean, supporting diverse marine life and coastal ecosystems. Proper treatment helps protect the health of nearby bays and inlets, which are important for local fisheries and recreation.

The plant discharges into coastal waters near Marystown, which are part of the larger Placentia Bay system. Placentia Bay is a deep, fjord-like inlet on the south coast of Newfoundland that supports rich marine biodiversity, including cod, herring, and shellfish. The bay's waters eventually flow into the Atlantic Ocean. Effective secondary treatment is crucial to prevent nutrient loading and protect the sensitive marine habitat from eutrophication and contamination.
