Event Meeting Location: ~ 10 minutes West of Prince George just of Highway 16. See attached PDF map. Google directions from PG, available here. Parking is limited, please carpool if possible. The tour will begin at the lagoon and vehicles may park at the gate leading into the lagoon off of the Highway 16 frontage road.

Event Summary: During this field tour the Citry of PG will tour the BCIA through Western Acres, an engineered sanitary lagoon and wetland. This site was adapted to accommodate the wastewater system from a creek and wetland that naturally existed beforehand. Primary treatment occurs upstream in the three-celled Lagoon. Blackwater (water from toilets) from the adjacent urban area goes through the three cells where it is broken down by the sun, wind, algae, and bacteria. Through the three-cell system, the blackwater is converted into cleaner greywater, as organic materials are broken down and sink to the base of the lagoon to decompose. The greywater is then discharged to Hiller Creek once it meets the proper conditions for coliforms (bacteria), total suspended solids (TSS), biochemical oxygen demand (BOD), and excess nutrients where it then moves to secondary treatment in the Wetlands.

Secondary treatment “polishes” the greywater by further reducing TSS and BOD through filtration through the wetland vegetation and natural mixing in the wetland. Microorganisms that live in the wetlands plants and soils remove any biodegradable material from the water through decomposition, and aquatic plants (such as cattails) absorb excess nutrients and carbon dioxide and produce oxygen. Once the water is fully treated in the wetland it returns to Hiller Creek. Discharge only occurs once water quality guidelines and creek flow conditions are met.

The lagoon provides excellent wildlife habitat for several species of birds, including geese and ducks, amphibians, muskrats and beavers. Wetlands are also important for ungulate species such as deer and moose because of the vegetation, and provides habitat for coyotes, foxes, and small mammals such as voles and squirrels.
