Title
UPDATE ON THE PROGRESS AND RESULTS OF THE ‘ICE PIGGING’ WATERMAIN CLEANING PROJECT
Background
In 2016 the City initiated a project to perform cleaning of our watermains using a technique called “Ice Pigging”, where slurry of ice and water is pushed through the water main scouring the deposits and build-up on the interior of the water main then flushing it out through our hydrants. Ice Pigging does not require additional excavation or connections made to the system.
The project approved funding to perform this work at a cost of $100,000 per year over a five-year period for a total of $500,000. Funds have been budgeted in the Water Fund to do this type of work.
Staff will have a short video available at the meeting to show how this process works, plus pictures, video, and some results of the work conducted so far.
Recommendation
Provide feedback on continuation of the project.
