The Niagara Region has launched a month-long public review regarding plans to expand the Baker Road Wastewater Treatment Plant in Grimsby. From May 11 to June 11, 2026, residents are invited to look over project details and share their feedback on the proposed capacity increase.
The facility at 160 Lake St. currently treats wastewater from homes, businesses and hauled sewage in Grimsby, Lincoln, and West Lincoln using an activated sludge process. To support the community’s projected population growth from 31,600 to 51,100 by 2051, the region aims to increase the plant’s daily treatment capacity by 16 million litres, bringing the total to 47.3 million litres per day.
This expansion is being managed as a Schedule ‘C’ Municipal Class Environmental Assessment. The project is designed to help accommodate new housing and job growth, including development associated with the planned Casablanca GO station. In addition to this expansion, a separate $9-million maintenance program is currently underway in Grimsby to address aging pipes and reduce unnecessary flow into the system, which has been linked to occasional overflows of partially treated water into Lake Ontario during heavy rainfall.
Residents can participate in this initial review process by visiting the project website to view display boards and a video presentation, and by submitting comments through an online form. Following this stage, the project will move into a conceptual design phase from summer 2026 to winter 2027.
Those with questions about the environmental study can contact Kevin Kortekaas, C.Tech, Senior Project Manager for Water and Wastewater Engineering at the Niagara Region, or Rina Kurian, the project manager representing the consulting firm R.V. Anderson Associates Limited.
