The City and its utility partner, Utilities Kingston, have released the final report on how to deal with the issue of bio-solids produced from treated sludge at the City of Kingston's three treatment plants.

Final report recommends enhancing existing process while continuing the current management system. |
Bio-solids are nutrient rich, organic by-products of the sewer treatment process and with pathogens removed, can recycled for application on agricultural land.
However, as scientific research and bio-solids legislation evolves, a short and long term plan for managing bio-solids was warranted say local officials.
The study looked at alternate bio-solids treatments and end uses with a view to public health, environmental sustainability, flexibility, and cost-effectiveness.
The study team investigated composting bio-solids, lime stabilization, turning bio-solids into pellets, incineration or discarding the material to landfill. They also looked at enhancing the existing bio-solids process while continuing the current management system already in place.
Indeed, the final report does recommend that in the short term, bio-solids may continue to be applied to agricultural land. Further, the report highlights the need for technical enhancements to be made to the Ravensview and Kingston West sewer treatment plants.
In the longer term, the report discusses possible changes to the bio-solids plan and confirms that flexibility has been built into the protocol.
Officials say that the plan's flexibility will help assure any future changes in regulations or technical innovations in the bio-solids management can be accommodated.
Hard copies of the report can be viewed at the central branch of the Kingston public library or at the municipal office located at 211 Counter Street.
