LAKE HURON WATER TREATMENT PLANT RESIDUE MANAGEMENT FACILITY PROJECT

History

When the Lake Huron water treatment plant located in Grand Brand was originally constructed in 1965, there were no restrictions on the discharge of process wastewater to the water source.  Currently, the water treatment plant uses centrifuges to dewater settled solids collected during the treatment process.  The solids produced are then trucked to a landfill for disposal.  Subsequently, the centrate produced by the centrifuges during the removal of these solids is partially treated then released into the natural water environment.

 Project Description

The project involves the completion of a Municipal Class Environmental Assessment, preliminary design, and detailed design prior to the construction of residue management facility located adjacent to the water treatment plant within the existing plant property.  This projects deals with the treatment of process wastewater from the treatment of drinking water to meet the requirements of the Ontario Water Resources Act and the Environmental Protection Act.  The requirement of this project is to ensure that the wastewater produced at the plant, as a result of the water treatment processes, is of acceptable quality and in accordance to provincial criteria, prior to discharge into Lake Huron and provide disposal of the plant’s dewatered solids. 

Funding for this project has been provided by the Government of Canada and the Province of Ontario under the Building Canada Fund and the HELP Clean Water Initiative.  The HELP Clean Water Initiative is a partnership between the Lake Huron Primary Water Supply System, the Elgin Area Primary Water Supply System, and the City of London to seek senior government funding for specified projects which have regionally significant impact to the water supply systems in this region of Ontario.
