TOWARDS A CLEANER RIVER Among the many benefits of a new nutrient recovery plant at Clover Bar is algae bloom reduction in the North Saskatchewan River.
LESS WASTE-FILLED THAN YOU MIGHT THINK An EPCOR facility in north
fertilizer pellets known to increase yields for canola, potatoes, and wheat. Over the next year, the plant will produce about 1,000 one-tonne bags of high-quality fertilizer. That’s about three bags each day, available to sell to farmers. The facility, unveiled before the media in September, generates some positive side effects, too. For the Clover Bar water treatment plant itself, removing phosphorus from the water means less build-

Edmonton is finding treasure in wastewater. Located at Clover Bar, the $18-million plant—built by APEGA permit holder EPCOR and Ostara Nutrient Recovery Technologies from B.C.—reclaims phosphorus and nitrogen from Edmonton wastewater. The facility
fewer clogs to deal with. Also, since phosphorous contributes to algae
blooms in rivers, extracting it from the North Saskatchewan makes it a healthier place for critters and humans.
