October Monthly Meeting
Hello PUG Members!

Steve Donovan from Underground Solutions will be presenting on Close Tolerance Pipe Slurrification (CTPS) for Trenchless Asbestos Pipe Removal and Replacement. CTPS is a new EPA, CA Air Board approved trenchless method for removing and replacing old AC water and sewer pressure pipelines with new Fusible C900 pipe. During CTPS, AC material is slurrified, removed by vacuum, and allowed to solidify into a safe transportable soil like material containing asbestos. Fugitive emissions are eliminated by the process while production removing and replacing AC pipe is significantly increased. This presentation discusses the latest from this exciting technology including review of costs from projects around the United States.
Please RSVP using the Google Form Link by Friday, October 9th, at 5PM.
