Water Treatment Plant Construction Update

Side-by-side comparison of the old vs. new: The final phase of construction includes demolition of the existing administration building on the left. Plant staff have now relocated into the new administration building on the right.

The new filters are now up and running and treatment plant staff have relocated into the new administration building! Plant staff are now operating the new system from their new administration building!

The startup of the filters and relocation into the new administration building kick-starts the third and final phase of construction, which includes demolishing the existing filters and administration building, installing the new ozone system and final site improvements, restoration and landscaping.

Information about onsite work is outlined below. Please note, schedules are subject to change.

Demolition - north of site

Throughout June, the contractor will be demolishing the existing filters and administration building located on the north of the site.

Over the next few days, crews will begin preparing for demolition. Starting next week, excavators with concrete processors (jaws) or hydraulic hammers will begin breaking up the concrete and the structures. During this work, there will be an increase in noise and potential vibration, depending on neighbors’ locations. In the past, crews have needed to use the hydraulic hammer more frequently at times to break up the concrete in the bases of the foundations. Unfortunately, use of the hydraulic hammer is a very noisy activity. Crews will aim to use the concrete processors (jaws) as much as possible.

This demolition work is expected to take a month to complete, and will be the final demolition activities to occur at the plant. The concrete will be stockpiled and crushed on-site as the work continues. Crushing the material for later reuse on site reduces truck traffic in the neighborhood.
