Tertiary Treatment Upgrades, New Chlorine Contact Tank and Improvements to Red Hill Creek |
Improved Effluent Quality: Addition of a tertiary treatment process to allow the Woodward Wastewater Treatment Plant to meet stringent Hamilton Harbour Remedial Action Plan targets. Maximizes Plant Hydraulics: Dedicated discharge location into Red Hill Creek required for tertiary treated effluent, and dedicates existing outfall for increased treatment of wet-weather flows. Red Hill Creek: Improvements, including widening, of Red Hill Creek between the new and existing outfall to convey the new tertiary treated effluent. |

| Main Wastewater Pumping Station Upgrades |
Increased Capacity: Meet future wet-weather capacity needs of 1700 MLD. Improved Conveyance: Larger and deeper wet well to mitigate system flooding, provide increased system storage and reduce solids buildup during dry weather flows. Improved Maintenance: Split wet well design allowing for half of the wet well to be taken off-line for maintenance, while pumping station remains in operation. |

| Electrical and Chlorination System Upgrades |
Replace Aging Assets: Reduce risk by replacing critical assets at the end of their useful life. Increased Standby Power: Provide sufficient standby power to all essential loads. Energy Efficiencies: Maximize energy efficiencies wherever possible. |
Electrical Upgrades - Contract 2 Renderings: Final 2nd Draft, Eye |
Contractor: Alberici Constructors, Ltd. Construction began October 10, 2017. Foundations for the Electrical Power Centre building are nearly complete and construction of masonry and steel for the structure continues.
