About The Project
THE WELLAND Water Treatment Plant (WTP) supplies potable water to Welland, Pelham, and parts of Thorold.

The plant sources water from Lake Erie via the Welland Canal and has a total capacity of 102.3 million litres per day, serving around 50,000 residents.
Recent upgrades include a new reservoir, UV/High Lift Pump Station, substation, and standby generator to enhance reliability. A new transmission main and water/sewer main replacement
