Hamilton’s main wastewater treatment facility will be upgraded, which is a change in scope from last year’s guide when it included an expansion component. The main objective of this future work is to improve effluent water quality and increase treatment for wet weather flow. The program will be delivered through several sub-projects, including a new 1,700-megalitre-per-day raw-sewage pumping station and improvements to secondary and new tertiary treatment (with the exact treatment technology yet to be selected). Also included is a new chlorine contact tank, a new tertiary effluent outfall, upgrades to the Red Hill Creek (such as widening the creek and works to mitigate erosion), upgrades to the power supply, electrical distribution system and standby power, and other ancillary upgrades. The long-term goal of this initiative is to improve the quality of effluent flowing into Hamilton Harbour and ultimately making a significant contribution toward de-listing the harbour as an “area of concern” identified under the Great Lakes Water Quality Agreement.
