In order to meet the anticipated demand increase while also shifting to utilizing surface water in Texas, the Luce Bayou Interbasin Transfer Project (LBITP) will transfer existing surface water rights held by the City of Houston in the Trinity River to Lake Houston in the San Jacinto basin. The LBITP is a $318 million water supply project that includes a 500 MGD pump station (located on a 90-acre parcel), approximately 3.6 miles of pipelines, setting basin and maintenance facility, 23 miles of open canals to convey the untreated water to an outfall structure at Lake Houston. One of the critical components of the LBITP is the pig retrieval station. The components at the pig retrieval station needed to withstand not only the forces of the day to day operations, but also accommodate the settlement presented by the terrain.

Brown & Gay Engineering, Inc. (BGE, Inc.) chose to utilize Victaulic system solutions, which included the Style W77 AGS Flexible Coupling and the Style W257 Dynamic Movement joint. These products provided fully restrained system solutions that met the design criteria of withstanding the forces of the day to day operations while simultaneously achieving the goal of reducing the size of the vault. By using the W257 joints, BGE, Inc. could achieve 4 inches of settlement in approximately 22 feet on this installation. Traditional methods would have required more than twice the excavation to install restraining devices, such as an M11 harness.

此外，唯特利AGS W77型挠性接头为进入隔离系统、清洗和回收区域提供了一种快捷、简单的方法。AGS W77型接头提供了灵活的解决方案，以便在日后日常系统维护或不当关机的情况下进入系统。

Victaulic’s mechanical capabilities provided inherent value engineering that minimized construction costs and schedules while overcoming the challenges presented by the pig retrieval station.
