Title: Fast-Growing Hooper, Utah Utilizes Vacuum Sewer Technology

Author: Steve Gibbs

Description: Fast-growing Hooper, Utah, (population 5,500) was the largest unsewered city in the state when it Incorporated in 2000. The site characteristics and topography of the area made gravity sewer installation difficult, disruptive and expensive. Seeking a better alternative, the city did extensive research on several conveyance methods and determined that vacuum sewer technology by AIRVAC was the best solution.

AIRVAC helped the city avoid several difficult problems. Vacuum collection lines can be buried in shallower trenches, eliminating the need for deep excavation and dewatering. This greatly reduced installation time and minimized traffic disruption. Hooper's Vacuum sewer required only three vacuum stations to serve the entire town, compared to 15 pumping stations that a gravity sewer would have needed. As a result the city saved about 25 percent by utilizing AIRVAC technology rather than gravity sewers.
