The City of Clarence-Rockland (City) is rapidly growing resulting in a significant increase in drinking water demand and the requirement for additional drinking water supply and conveyance to meet the forecasted demands. The City undertook a study to identify and evaluate options to expand the Rockland Water Treatment Plant (WTP) supply capacity (Figure 1) and the Caron Booster Pumping Station (BPS) pumping capacity (Figure 2). The need to expand the Rockland WTP and Caron BPS was identified in the 2021 Water Master Plan based on the population and water demand forecasts.

The Study Process 

The study was carried out as a Schedule C Municipal Class Environmental Assessment (MCEA). The study completed Phases 1-4 of the MCEA process. The recommended solution to expand the Rockland WTP and Caron BPS is documented in an Environmental Study Report (ESR). Following the completion of the study, the City intends to proceed with the implementation of projects identified in the implementation plan.

Environmental Study Report 

An electronic copy of the Environmental Study Report is available on the Project Webpage at: https://www.clarence-rockland.com/en/city-hall/plans-reports-studies/expansion-rockland-water-treatment-plant . By this notice, the Expansion of the Rockland WTP and Caron BPS Environmental Study Report is being placed on the public record for a 30-day public review period ending on July 13^th, 2026, in accordance with the requirements of the MCEA process.

Expansion of the Rockland Water Treatment Plant and Upgrade of the Caron Booster Pumping Station

The Study

The City of Clarence-Rockland (City) is rapidly growing resulting in a significant increase in water demand and the requirement for additional water supply and conveyance. The City is undertaking a study to identify and consider options to expand the Clarence-Rockland Water Treatment Plant (WTP) supply capacity (Figure 1) and the Caron Booster Pumping Station (CBS) conveyance capacity (Figure 2). The need to expand the Clarence-Rockland Water Treatment Plant and Caron Booster Pumping Station was identified in the 2021 Water Master Plan.

The Study Process

The study will be carried out as a Schedule C Municipal Class Environmental Assessment (MCEA). The study will complete Phases 1-4 of the MCEA process. The recommended solution to expand the Clarence-Rockland WTP and Caron BPS will be documented in an Environmental Study Report (ESR).

Opportunities for Participation

Consultation with interested parties, including the public, is an important part of the MCEA study process to identify areas of interest. Two public meetings (public information centers) are planned throughout the study process to connect with the project team, learn about the study, and facilitate feedback.

Upon completion of the study, a Draft ESR file will be prepared and available for public review for a minimum of 30 days.
