An Airvac Vacuum Sewer system uses small diameter pipe laid in shallow trenches with no manholes. As a result, the cost to install a vacuum system is almost always less than a gravity flow system. Once installed, the savings continue as the tight system does not allow infiltration and inflow (I&I). This is especially important when treatment is being provided by others on a cost per gallon basis.
More Lots Available for Sale
One Airvac vacuum station typically replaces five or six lift stations necessary in a gravity-flow system, resulting in additional lots available for profitable home sites. An added benefit is the elimination of hard-to-sell lots that are located adjacent to these lift stations.
