Hydraulic pipe pigging was utilized by Montauk Services during a recent project in Canada to clean invasive quagga mussels from three large-diameter freshwater intake pipelines. The deep-water intakes, each more than 3 miles long, bring water from Lake Ontario into the Island Water Treatment Plant owned by the city of Toronto.
In 2018, the City of Toronto initiated a project with Montauk Services to clean three sixty-inch diameter HDPE raw water intakes at the Island Water Treatment Plant, restore intake flow to its original design specification, and reduce plant operating costs.
Montauk Services is one of North America's most experienced pigging and testing companies. They are pioneers in the pigging of water and force mains for over 37 years. Montauk has heard continual requests by Engineers and Municipalities for a free flowing pig that could determine wall degradation in cast iron ductile and steel mains.
