Fallingwater, designed by Frank Lloyd Wright, is renowned as one of the most unique homes ever built in America. The home, an historical site visited by thousands of people each year, cantilevers over Bear Run in western Pennsylvania. The Western Pennsylvania Conservancy had strict requirements for sewage disposal when Fallingwater underwent its massive restoration.

Historical site meant strict requirements for excavation and grinder pump location.

Sewage needed to be collected from several buildings, then pumped uphill to the treatment plant.

Directional drilling was used to install the sewer lines, protecting the existing plants and trees. The E/One Sewer system met the requirements of aesthetics and seasonal high flows.

“All of the pump covers … blend into the environment … Aesthetics are very, very important. There are two pumps by the main house and the guest house, and no one knows that they are there.”
— Jeff Gaul, Director of Maintenance

Today, the E/One Sewer system is virtually invisible to visitors.
