The Skyway WWTP Phase 2 Expansion project will produce treated wastewater effluent that meets the highest national standards established by the Canadian Council of Ministers of the Environment, and the Remedial Action Plan (RAP) for Hamilton Harbour - an Area of Concern (AOC) in the Great Lakes Basin. BACKGROUND The Skyway WWTP is located at 1125 Lakeshore Road within the City of Burlington. The plant provides wastewater treatment for the City of Burlington as well as a small portion of the Town of Oakville. A Schedule C Municipal Class Environmental Assessment (EA) was completed in December 2009 to evaluate alternatives and determine the preferred design concept for expanding the Skyway WWTP from 118 (million litres per day) MLD to 140MLD. The Skyway WWTP Expansion project was awarded the Green Infrastructure Fund, which targets projects that will improve the environment and lead to a sustainable economy over the long term.
