Constructed in the early 1970’s, the Walker-Calloway Branch Outfall Trunk Sewer System (W-C) is owned and maintained by the Trinity River Authority (TRA). Flows discharge into the 96-inch City of Fort Worth Village Creek outfall where collapses, surcharging, and backups were recurring. This multi-phase program began with a condition and capacity assessment to understand current conditions, the remaining useful life (RUL) of the pipe, risks of failure, and project future capacity needs for the 2040 planning horizon.
The W-C improvement program structured recommended repairs into seven phases. The Preliminary Design Report (PDR) identified that approximately 90% of the system required rehabilitation, with the majority of work recommended to be rehabilitated by trenchless methods.
