Trinity River Authority of Texas (TRA), Henrietta Creek Regional Wastewater System 25HC-1, Dallas, Texas

CRIADO provided the preliminary engineering phase evaluation and development of the proposed 25HC-1 Relief Interceptor Project (part of Denton Creek Regional Wastewater System’s (DCRWS’s) Henrietta Creek Interceptor Subsystem) located in western Roanoke and northern Fort Worth. The project began at manhole 460H located approximately ½-mile south of the Cleveland Gibbs Rd and State Highway 114 intersection. The 25HC-1 Project consisted of 11,900 linear feet of 48-inch and 54-inch sanitary sewer pipeline paralleling the existing 30-inch interceptor. It also included the upsizing of one siphon located between manholes 480H and 500H. CRIADO provided the Condition Assessment Technical Memorandum (“TM-1”) regarding the general condition of the pipeline, manholes and structures. Our team developed preliminary pipeline profiles for proposed options, alignment recommendations, and compiled data including flow projections, condition assessments (TM-1), permitting issues, and other items in the Preliminary Design Report.
