Sewage generated from the 50 man gas plant facility in a remote section of the north Peace River required updating to meet with current regulatory requirements. Secondary treatment and disinfection of the wastewater was added upstream of the existing storage lagoons. The treated effluent, which meets Ministry of Environment reclaimed water standards, is stored in the lagoons over the winter months and used to irrigate the neighboring forest during the spring and summer months when the ground is no longer frozen. An automated system was designed by ACE which cycles through 5 irrigation zones or sets incorporating a 10 hour irrigation period followed by 3 days of rest. The reclaimed water or effluent is applied via spray irrigation in order to reduce infrastructure costs and optimize evapotranspiration and provide a more uniform hydraulic loading to the ground.
