PORTAGE LA PRAIRIE, MB, and VANCOUVER, BC, July 1, 2014 — The City of Portage la Prairie’s Water Pollution Control Facility (WPCF), located in the Central Plains Region of Manitoba, Canada, is implementing a pilot program to evaluate innovative technologies that help manage nutrient loads treated at the facility.

One such technology is the Ostara Pearl® process, developed by Ostara Nutrient Recovery Technologies, which recovers phosphorus from treated wastewater streams and transforms it into an eco-friendly, slow-release fertilizer. The process will not only help the plant meet new phosphorus discharge limits but would provide an additional source of revenue to the city — all while helping to protect the local watershed.

Portage la Prairie is a part of the massive Lake Winnipeg watershed, which is the focus of a concerted provincial environmental policy effort designed to reduce nutrient runoff entering the lake. Excess phosphorus contributes to the growth of algae, which chokes off sunlight and oxygen, destroying aquatic life. As part of its comprehensive water strategy, the province has identified nutrient management initiatives as a key driver of water quality.

“While the primary goal of this pilot program is to provide strategic options to help us meet nutrient discharge obligations, it also allows us to play an active role in supporting the province’s efforts to reduce the environmental impact of nutrient pollution on the Lake Winnipeg watershed,” said Kelly Braden, director of operations at the facility.
