The rapidly growing City of Cranbrook has upgraded its wastewater systems to improve effluent quality, reduce operating costs, cut GHG emissions and allow for population growth over the next 20 years.
Cranbrook's current wastewater treatment system, which was cutting-edge when it was built more than 40 years ago, uses reclaimed water to irrigate agricultural lands, boosting the local economy. Building on that legacy, the upgrades include a new storage pond, and aeration and disinfecting equipment that that treat sewage with natural biochemical processes. Reclaimed water from the improved system exceeds health and safety standards and can be used to irrigate recreational as well as agricultural lands.
Restoring and upgrading Cranbrook's existing facility has created a showpiece for efficient wastewater management. The upgraded system produces lower GHG emissions, uses less power and has significantly lower operating costs.
Cranbook's wastewater improvement project was the 2012 FCM Sustainable Communities Awards winner for water.
Engaging the entire community in the project was a challenge. Council emphasised building relationships within the community and surrounding area and with stakeholders including provincial agencies and local First Nations.
