Vacuum sewers were first installed in Europe in 1882 but until the last 30 years it had been relegated to a niche market. A vacuum sewer uses the differential pressure between atmospheric pressure and a partial vacuum maintained in the piping network and Vacuum station tank. This vacuum differential pressure allows a central vacuum station to collect up to 1500 individual homes depending on terrain. Vacuum sewers take advantage of available slope in the terrain and are most economical in flat sandy soils with high ground water.

The county of Sarasota Florida is developing a county wide collection system and is incorporating vacuum sewers.
