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.

En outre, les colliers flexibles style W77 AGS Victaulic offrent une solution rapide et facile pour accéder aux systèmes d'isolation et aux zones de nettoyage et de récupération. Ils permettent désormais d'accéder facilement au système en cas de maintenance de routine ou d'arrêt inopiné.

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