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.
Pigging Restores Intake Flow Capacity Fouled by Quagga Mussels
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.
