Online Consultation: Mid-Halton Wastewater Treatment Plant Upgrades

About the project

Study overview

To accommodate growth into 2031, Halton Region is considering options to increase the capacity of the existing Mid-Halton Wastewater Treatment Plant (WWTP) from 125 million litres per day (ML/d) to 195 ML/d.

The upgrades will maintain reliable wastewater services for these areas and provide capacity for new homes and businesses. The social, cultural and environmental impact of these improvements will be assessed throughout the study.
