When considering wastewater management, the City of Hamilton takes a pro-active approach to ensure that they are fiscally responsible. With the Waterdown Wastewater Treatment Plant it became apparent that there was a better way to handle the wastewater processing requirements. The decommissioning of the plant began in 2007 and was completed in 2016. With a budget of $8.2 million, the Municipal Class Environmental Assessment Master Water and Wastewater Plan indicated that the preferred alternative was to decommission the plant and replace it with a pumping station.
How does it relate to the Hamilton Harbour Remedial Action Plan (HHRAP)?
The primary focus of the HHRAP is to reverse past environmental damage and protect Hamilton Harbour from future damage. The decommissioning of the plant helps to achieve these goals. Effluent wastewater flowed from the Waterdown plant to Grindstone Creek, which is a cold water stream fish habitat that flows to the harbour. It was deemed in the environmental assessment that the water quality would be better for the fish without the wastewater effluent flow. This would, in turn, help the fish in the harbour that spawn in the creek. The decommissioning was the preferred alternative to socially and cost effectively mitigate any further environmental damage. It was also cost-effective to treat wastewater at the Dundas Wastewater Treatment Plant instead of the current Waterdown plant.
How does it relate to the Clean Harbour Program?
The Clean Harbour Program is aimed at reversing the environmental damage to Hamilton Harbour. By developing a more efficient and better environmental way to manage wastewater in Waterdown, this supports the goals of the Program.
Promoting local development
This specific project promotes development in Waterdown as it provides efficient wastewater treatment to the area without affecting local waterways. A pumping station was built to collect sewage flow to be pumped to the Dundas Wastewater Treatment Site. Then a sanitary forcemain and sewer was constructed to connect the pumping station to Borers Creek sanitary sewer interceptor. The flow is then allowed to flow to Dundas Wastewater Treatment Plant or pumped to Woodward Wastewater Treatment Plant. This also allows for increased capacity for overflow events by utilizing and converting plant aeration tanks into overflow tanks when needed.
What is the return-on-investment for the residents of Hamilton?
The new process in treating wastewater for Waterdown is efficient, cost-effective, and protects our environmental resources.
