Water Treatment Plant Doors Open Peterborough

Water Treatment Plant

Peterborough’s Water Treatment Plant was constructed between 1920 and 1922 and has been providing the city with clean drinking water for almost a century. Explore this interesting example of early 20th-century industrial architecture and learn about how the city’s water supply is treated. Tours will operate on an as-needed basis.
