Description
The City of Saskatoon’s water treatment plant discharges a non–toxic cold lime softening and ferric sulphate coagulantsludge directly into the South Saskatchewan River. The area is used heavily for recreation and the discharge is aconcern to the public, tourism operations, and the Meewasin Valley Authority (MVA).The project will design and construct a sludge reclamation facility that collects water treatment wastes for utilization atthe city’s landfill. The sludge discharges will be entirely eliminated. The dewatered sludge will then be mixed with soil andused as cover dirt at the landfill – a unique approach. Eliminating the discharge will ensure the sustainability of the water treatment plant as an acceptable operation in a sensitive residential area and within recreational and conservation plansfor the river valley.A lifecycle assessment of trucking vs. pumping the sludge will be part of the project analysis as well as environmentaland energy impacts.
