The Brushy Creek Regional Utility Authority is coordinating the construction of a three-phase Regional Water Supply System to treat and deliver water from Lake Travis to the cities of Cedar Park, Leander, and Round Rock, Texas. NHC provided extensive hydraulic design support for the Phase 2 deep raw water intake, the 142 mgd pump station, and the conveyance pipeline. Technical components included input for conceptual design development; Computational Fluid Dynamics (CFD) modelling of the lake intake and four pump station design alternatives; hydraulic transient analysis and development of surge control alternatives; and physical modelling of the selected pump intake alternative to achieve a design that meets the Hydraulic Institute Pump Intake Design Standard. These hydraulic modelling techniques were coupled with insights and recommendations based on NHC’s unique degree of specialization to help develop a design that will provide a reliable water source during prolonged droughts.
