Woodward Wastewater Treatment Plant Upgrades
Woodward Wastewater Treatment Plant Upgrades
The largest investment of the Clean Harbour program was a multi-phase plan to upgrade the Woodward Wastewater Treatment Plant. Because the plant is the largest single source of water flowing into Hamilton Harbour, the quality of that effluent has a direct and powerful impact on the harbour’s water quality and environmental health. The capital construction cost for the upgrades was approximately $340 million, $200 million of which comes from the provincial and federal governments through the Green Infrastructure Fund.
The upgrades include elevating the plant’s final treatment process from the secondary level to the tertiary (third) level. This allows the plant to reach strict discharge limits described by the Hamilton Harbour Remedial Action Plan for phosphorus, ammonia and suspended solids.

In October 2022, a crucial milestone was achieved as the secondary effluent started to flow through the Tertiary Treatment Facility, simultaneously initiating the commissioning period. This achievement signifies a momentous step towards transforming the Woodward Wastewater Treatment Plant from a secondary to a tertiary level treatment facility. Meeting this goal reflects the City's commitment to fulfilling the Hamilton Harbour Remedial Action Plan Targets.
