Ocean Shores, Wash., installed vacuum sewers more than 20 years ago. Its current data and O&M costs are now changing opinions about the durability and cost-effectiveness of vacuum sewer technology. It is the type of real-world experience that is indispensable to civil engineers and public works directors.

The Indian River Lagoon is a narrow channel of brackish water that extends nearly 160 miles down the spine of Florida’s Atlantic coast. While not as well known to outsiders as the Everglades or Florida Keys, the Indian River Lagoon (IRL) is an “estuary of national significance” and is vitally important to many species of wildlife, including endangered manatees and sea turtles. The estuary also contributes significantly to Florida’s economy. For those reasons, the environmental health of the IRL is, in many ways, essential to the health of Florida’s east coast.
Fast-growing Hooper, Utah, was the largest unsewered city in the state when it incorporated in 2000. At the time, almost all Hooper residents were relying on septic tanks and drain fields, which were contaminating the ground water. Hooper can handle more growth in the coming years because the city has installed an award winning AIRVAC vacuum sewer system that is cost effective, reliable, easily expandable, and requires very little maintenance.
The Village of Alloway, NJ had been looking to replace its septic tanks for decades, but cost and inconvenience delayed the project until 2007. Alloway’s new AIRVAC vacuum sewer system saved taxpayers approximately $1 million compared to installing gravity sewers and the project won a statewide Municipal Engineering Award.
