In 2011, the City of Dallas faced a potentially expensive municipal emergency when the nearly 60-year-old wastewater main pipe collapsed. The city conducted a video inspection that revealed extensive corrosive damage due to high levels of hydrogen sulfide gases and issued an emergency repair. Original repairs suggest using open cut rehabilitation methods; however, due to a nearby renovated park, the DWU opted to explore alternative options for the pipe replacement. Together, the City of Dallas and Omega Contracting Inc. (OCI) elected IPR South Central division.

IPR South Central is a leading provider of underground rehabilitation solutions and the largest pipe bursting contractor division in the nation. Due to IPR South Central’s reputation in the pipe bursting industry, IPR South Central was the ideal candidate for the project. The rehabilitation project would replace the damaged pipe with a new 42 inches in diameter HDPE and increase the length to a 3,420-lf stretch. The larger pipe diameter will reduce the chronic flooding issues from before.

During the opening stages of the project, IPR South Central worked with Dallas’ Parks Department to devise an efficient and non-disruptive timeline for construction. The project location crossed under Fair Oaks Avenue through Harry Moss Park. About 700-lf of the project was located through a heavily wooded area and adjacent to a retention pond. However, IPR South Central’s most significant concern was the baseball fields and recreational parks. The uneven terrain, two creek crossings, water-saturated soil and technical difficulties posed as a potentially enormous threat to the environmental impact on the community. IPR South Central needed to work fast, effectively and earnestly during the rehabilitation.


IPR South Central performed the pipe bursting rehabilitation solution. About 2,234-lf of the project would be replaced using pipe bursting techniques, 189-lf would use the CIPP method, and 997-lf would be done using open-cut. Using these trenchless methods for repair allowed a faster restoration time, less overall expense, and minimal disruption. IPR South Central worked with OCI on supplying two 18-inch lines to carry bypass and drained out the retention pond to reduce any disturbance.


In result of IPR’s access to an abundance of trenchless repair options, the project was a financial and logistical success. Dallas officials did not receive a single complaint during the project and residents were able to continue their daily routines. The repairs surpassed the expectations of the city in addressing the corrosion problems, increasing the diameter of the pipe, restoring structural integrity to the line and improving its drainage. IPR’s innovative use of its solutions and positive collaboration with its parties enable a successful outcome for the City of Dallas.
