Victoria, BC – The Capital Regional District’s Core Area Liquid Waste Management Committee (CALWMC) has approved an amendment to the existing Liquid Waste Management Plan, which gives system specifications for the region’s wastewater treatment project. Pending approval by the CRD Board, on December 9, the plan will be submitted for final approval to the BC Ministry of Environment by the end of 2009.
“The committee has put together a system which will emphasize opportunities for resource recovery, water reclamation and bio-methane in the Core Area,” said CALWMC Chair Judy Brownoff. “I am pleased to say that the project will cost considerably less than first thought, and create a system that operates carbon positive. The system will also integrate the West Shore in the plan for wastewater treatment—siting is underway in these municipalities and we will see the construction of a cohesive wastewater system.”
The cost of the system is estimated $967.5 million and includes the potential for more than 18,500 tonnes of carbon offsets per year. Included in the system is a Saanich East-North Oak Bay (SENOB) liquids only plant at the Finnerty/Arbutus site, a treatment plant at McLoughlin Point in Esquimalt, a treatment plant in the West Shore, a Clover Point wet weather facility and an energy centre facility. Annual resource recovery revenues are estimated at $5.7 million by 2030 and $13 million by 2065. Resource recovery for the system will also include phosphate recovery and bio-methane generation. Annual operating costs for the system are estimated at $19.8 million per year, with a per household cost of $250-$450 per year, depending on the municipality and structure of cost sharing agreements. The committee also took the step of saying they would not support land application or soil amendments from biosolids.
“The CRD will continue to investigate opportunities to refine the system components that will improve the economic performance of the system and reduce any negative environmental or neighbourhood impacts,” said CRD Board Chair Geoff Young.
Future work will include the continued development of partnerships in research, learning and public education centres, which will work toward the further reduction of Greenhouse Gas emissions. The amendment includes a plan to continue to work with the District of Saanich and the University of Victoria on a SENOB site that may provide better benefit to the project; work will also continue on evaluating alternative sites for biosolids or combined biosolids/liquids processing in the Victoria Upper Harbour. The CRD will also submit a technical paper on the possible deferral of the Clover Point facility. A business case for the West Shore facility and site details, as well as final business case scenarios, procurement analysis and governance reviews are expected to be submitted in February 2010. The West Shore system will likely operate as an autonomous sub-committee of the CRD, similar to the Saanich Peninsula Wastewater Committee.
In 2006 the CRD began planning to upgrade its wastewater treatment at the request of the Minister of Environment for British Columbia. The Core Area includes the municipalities of Colwood, Esquimalt, Langford, Oak Bay, Saanich, Victoria and View Royal. Planning and construction of the wastewater treatment system is expected to take 10 years to complete.
