On August 14, 2012, the Project Team presented information to City Council and asked for a resolution to proceed with planning and further environmental review of a proposed site and treatment process for the City’s new wastewater treatment plant. Three alternatives were presented: an MBR plant at the Windjammer Vicinity; an Activated Sludge plant at Crescent Harbor North; and an MBR plant at Crescent Harbor North. After listening to the presentation and considering public comment, City Council voted unanimously on a resolution to move forward with an MBR plant at the Windjammer Vicinity.
