The Intergrated Pipeline Project ( or IPL) is a massive, 150-mile water supply pipeline from East Texas to the Dallas/Fort Worth metroplex. Throughout the life of the project, TRG has provided 150 miles of QL “D” SUE research and mapping; designated QL “B” SUE over a large majority of the 150-mile route, and is currently providing QL “A” SUE test hole services at critical design locations.
