Scope of Work

The refurbishment of the Williamstown WWTF involved demolition of the existing headworks and blower building, as well as the construction of a new Control Building, which included:

• New Headworks and Screening Facility
• New Blower Room
• New Chemical Feed Facility
• New Electrical System with Back-Up Power Generation
• New Controls and Building Management Systems
• New Chlorine Contact Basin

Because of site constraints, the new facilities had to be constructed in the same locations as the existing process footprint. This overlap required a temporary Blower System, Influent Sampling, as well as, installation of multiple bypasses for flow diversion during construction.

Phases

1. Build Temporary Facilities
2. Construct New Control building & Chlorine Contact Basin
3. Divert flow, Start-Up & Recommission of the Plant

Safety

This project reached full completion in June 2017 and over the 11 month period, there were zero accidents.
