Colwood Facility Benefits

• Longer term – water reuse for irrigation, toilet flushing, ground and creek enhancement

• Heat recovery to local buildings

• Biosolids dried, used as fuel

Proposed Location: Under Westshore Park & Ride

Vision for a Colwood Resource Recovery Centre

Financial Implications

• No change to design of main plant – adds 4-5 years capacity for other core municipalities

• Modest short term cost to other municipalities – about $16 per household per year, BUT

• avoided future cost of about $250 per year for WestShore plant

• Colwood is not seeking to have its ‘share’ of the federal/provincial grants

• Colwood will leave $ already contributed
