60" WASTEWATER REHABILITATION FROM TRINITY RIVER TO ROCHESTER SWPS

Project Description: The project involves the trenchless rehabilitation of a total of approximately 5,150 linear feet (LF) of a circa 1950’s 60” RCP gravity wastewater pipe, the replacement of existing manhole structures, reconstruction of existing manhole structures and the rehabilitation of existing manhole structures. All existing manhole structures are steel reinforced concrete.
The project involves rehabilitation of approximately 4,790 LF by Machine Spiral Wound Liner (MSWL) and approximately 360 LF of CIPP followed by HDPE slip lining for the portion of the pipeline crossing the Trinity River. A section of the pipeline crossing the Trinity River is exposed to river flow. Flow control to complete the rehabilitation will include the coordinated diversion of flow using the upstream DWU Sunbeam Diversion Structure. Pipeline rehabilitation work is to proceed in accordance with the Flow Control Provisions found in the Contract Drawings.
The pipeline rehabilitation extents are from the west side of the East Branch of the Trinity River east to near the existing Rochester Stormwater Pump Station (SWPS) located near William Blair Jr. Park in South Dallas. A portion of the pipeline parallels and crosses an Oncor High Voltage Transmission Tower ROW and crosses both an active UPRR ROW and TXDOT ROW.
The entire pipeline alignment is in the FEMA Regulatory Floodway and the area will be subject to flooding. Additionally, portions of the existing pipeline and/or project area are in United States Army Corps of Engineers (USACE) Lamar Levee Extension Project Area and portions parallel the Rochester Levee both of which are subject to USACE jurisdiction. Project Manager: Joe Felipe, P.E.
Final Specifications, Drawings, Bid Proposal Spreadsheet, and any procurement documents will be uploaded to Bonfire no later than Friday, May 8, 2026.
