Cedar Creek Section 4 Pipeline Replacement and Cedar Creek Lake Pump Station Improvements

The Cedar Creek Section 4 Pipeline Replacement and Cedar Creek Lake Pump Station Improvements project, solicitation 26-088, involves extensive infrastructure upgrades managed by the Trinity River Water District in Texas. The scope of work is divided into three primary components: the installation of approximately 8.3 miles of 90-inch welded steel pipeline from the Cedar Creek Pump Station to a tie-in east of the Trinity River, chemical feed system improvements at the Cedar Creek (CC1) Pump Station, and the installation of monolithic isolation joints at the Ennis (CC2) Booster Pump Station. Key activities include demolishing 780 linear feet of existing PCCP header and yard piping, installing 885 linear feet of new header and yard piping, plugging and grouting 507 linear feet of existing 72-inch PCCP, and integrating new low- and high-head caustic feed systems. The project also requires the installation of two 72-inch venturi meters with vaults and the completion of three trenchless tunnel crossings, including one crossing at SH-274 under TxDOT control. The contractor is responsible for coordinating with external agencies including TxDOT, ARCOSA, and various county road authorities for permitting and access. A critical requirement is the maintenance of continuous operation for the critical ductbank throughout construction. Due to the pipeline alignment being located within 10-year and 100-year floodplains, contractors must provide a detailed work plan addressing potential flooding and access impacts, particularly between February and June. Additionally, the project involves owner-furnished equipment, specifically two 72-inch and one 90-inch butterfly valves, with an anticipated delivery window between November 20, 2027, and December 24, 2028, requiring the contractor to re-mobilize for installation upon delivery. Proposals are due by September 25, 2026.
