- Q365634 abstract "A vacuum sewer system is a method of transporting sewage from its source to a treatment or disposal facility. It uses the differential pressure between atmospheric pressure and a partial vacuum maintained in the piping network and vacuum station collection vessel. This differential pressure allows a central vacuum station to collect the wastewater of several thousand individual homes, depending on terrain and the local situation. Vacuum sewers take advantage of available natural slope in the terrain and are most economical in flat sandy soils with high ground water.Vacuum sewers were first installed in Europe in 1882 but until the last 30 years it had been relegated to a niche market although it has reamined in use on trains and airplanes. The first applied use of negative pressure drainage (so called vacuum sewerage) was the Dutch engineer Charles Liernur in the second half of the 19th century. Technical implementations of vacuum sewerage systems were started after 1959 in Sweden by Joel Liljendahl and afterwards brought onto the market by Electrolux. Nowadays several system suppliers offer a wide range of products for many applications.".
