Ice pigging creates clean mains and water quality insights / Roger Miller; Eric Duderstadt; Paul Trelgar.

Abstract: Ice pigging is a sustainable, powerful cleaning method for potable water distribution mains and wastewater force mains. Suitable for all pipe materials, the ice pigging process involves pumping a slurry of ice into a main through a hydrant or other existing fitting, using system pressure to carry the ice "pig" downstream.
