Thrust Restraint Design Program (TRDP)TRDP was specifically developed by ACPPA and the consulting firm of Simpson, Gumpertz & Heger of Boston, MA to aid in the design of restraint systems for concrete pressure pipelines in accordance with the manual of water supply practice, M9 - Concrete Pressure Pipe, 3rd Edition (Chapter 9) and related AWWA Standards for Concrete Pressure Pipe, as published by the American Water Works Association (AWWA). The interactive software provides users with an accurate and reliable design program that complies with all applicable standards and simplifies the process of designing thrust restraint systems.Note: This software is intended for use by licensed Professional Engineers experienced with the techniques for restraining concrete pressure pipe. Non-licensed engineers and technicians may use this software after appropriate training and under the direct supervision of a licensed Professional Engineer.
