Client: Gulf Coast Water Authority (GCWA)
Location: Galveston, TX

GCWA supplies the City of Galveston with water through two existing water line systems. However, concerns about the condition of the existing water line and redundancy in their system prompted the City of Galveston to pursue the construction of an additional water line attached to the existing IH-45 bridge to Galveston. The third water line will require GCWA to increase the pressure in its existing system.

Aurora was selected to develop the design for two (2) 20″ above-ground flow control and metering stations to control pressure and flow to the existing water lines supplying Galveston. The flow control stations were metered through the use of full-port electromagnetic flow meters and pressure was controlled through a Cla-Val Pressure Reducing Valve with pressure relief, pressure sustaining, and pressure reducing functionalities. The project also required the design of 700 LF of existing cast-iron water line removal and replacement and an elevated structure for mounting SCADA and Solar­Power Battery Back-Ups.

Aurora’s efforts included the evaluation of the optimal location for stations, the development of piping and structural design, and construction-phase services of the project. Aurora also supported the GCWA staff in locating an existing leak and identifying options for field repairs.
