    Fused PVC Provides Alternative for Trenchless Pipe …

    “We had learned through talking to the representatives on both sides that PVC is a more rigid pipe, so when they’re pulling it, it tends not to elongate as much as an HDPE pipe would. So, it would relax quicker and we wouldn’t have to wait as long to work on the pipe once you’ve pulled it through,” said Tom Cieslik, a project engineering manager at El Paso Water Utilities.
