Liernur Pneumatic systems (1866)

Pneumatic and mechanical operating vacuum sewage collection systems were first introduced in the second half of the 19TH century. In 1866, the Dutch engineer and former Captain in the U.S. Army – a Captain Liemur (1828-1893) – had introduced at a Congress in the city of Haarlem, in The Netherlands – his vacuum operating sewage collection system for toilet waste. He had introduced the definition of the so-called “black water” to describe toilet waste. The philosophy was based on the re-use of treated toilet waste for agriculture. In the same year (1866), the Liemur technology was registered as a patent in England and The Netherlands.

Liemur systems were installed in cities in The Netherlands – Amsterdam, Leiden, and Dordrecht. It was also introduced into Prague (Czech), Trouville (France), Hanau (Germany) and Stansted (in England).

The Liemur system in Trouville (France) was in operation even until the 1980s.

Captain Liemur was also a member of the German “Internationaler Verein gegen die Veruntreinigung der Flusse, des Bodens und der Luft” since its founding in 1877.

The “Preusische Regierung” was very much against the discharge of sewage into the rivers resulting in new laws from 1875, and about river pollution as listed in the “Ministerialverfugungen and Gutachen”.

For many other cities in Europe – such as Paris, Berlin, Munich, Stutgart, Stockholm, Zurich, and Baltimore in the USA – the designs were made by Liemur, and sometimes were partially installed and were never fully completed. The technical failures, and the low standards of technology, and the changing concepts in sewage collection have contributed to the fact that to date – none of these Liemur vacuum sewage systems are in operation.

However, with new technologies, vacuum system presents a new alternative to the gravity flow sewage system – which dates back to the Roman aqueduct system.

LAVAC System and associates from Europe are able to offer the latest in Vacuum System Engineering for the removal of wastewater in any Indoor Land Installations – that include condensate water from Air Handling Units, Coldrooms and Supermarket Refrigerated Displays – and Outdoor systems for Marinas and Boatels. Special vacuum systems are available for the passengers on Trains and Express Buses to experience toilet standards equal to that installed on Airbus and Boeing passenger planes.
