Cedar Creek Lake JCC1 Lake Intake and Pump Station, Integrated Pipeline Project
Tarrant Regional Water District
This joint venture between Dallas Water Utilities and the Tarrant Regional Water District will provide water to millions of north Texans by transporting water from Lake Palestine, Cedar Creek Lake and the Richland-Chambers Reservoir. At the heart of this progressive water supply project are the five primary pump stations conveying 350 MGD at ultimate build out supplied by more than 40 pumps ranging from 3,000 to 5,000 horsepower. JQ has been involved since the start of the schematic design for this project and has played an integral role in the structural design of all five stations. The Cedar Creek Lake Intake Pump Station (JCC1) design featured a 43-foot-deep concrete wet well structure hosting six intake tee screens and supporting seven vertical turbine pumps connected to the 108-inch-diameter pipeline. Detailed finite element models of the lake retaining wing walls cantilevering over 40 feet were produced, and multiple options were evaluated before implementing a buttressed wall and face shell wall. FEM also was performed in support of the frequency analysis of the primary pump support structures, recognizing all Hydraulic Institute and ACI guidelines. BIM modeling was used throughout the project to facilitate conceptual-level decision-making, detailed final design coordination and clash detection.
