Hamilton’s strategy for dealing with bio-solids is about to move to its next stage.
The city will be issuing a request for proposals in the new year from private sector companies looking to bid on the construction and operation of a facility to treat the 10 tonnes of sewage sludge that is produced each day in Hamilton.
Local Conservative M-P David Sweet has announced that the federal government will commit up to 23 million dollars, or one-quarter of the capital cost, under its P3 model of public-private partnerships.
It’s a model that Sweet says will shift risks related to design, construction financing, operations and maintenance of the project away from taxpayers, and onto the contractor.
Director of Water and Wastewater Dan McKinnon expects a range of options for dealing with the biosolids will be included in the proposals, from thermal reduction or incineration to approaches that would turn it into fertilizer.
Currently, the city’s sludge is spread on farmer’s fields.
