Pressurised Sewerage Systems (PSS)

Initially developed in the United States in the 1960's, pressurized sewerage systems PSS, became popular in the early 1970's in rural areas with high water tables or rocky ground - circumstances for which the implementation of conventional systems was impractical, uneconomical, or otherwise infeasible. The real worldwide break-through for pressure systems occurred with the development of submersible centrifugal pumps with grinders around 1980. These pumps were cheap, reliable and easy to handle; in addition they could pump raw sewage at high pressures through systems using small diameter pipes. Today, due to the high costs of gravity sewage systems, pressure sewers have emerged as one of the most popular and practicable of the collection system alternatives, especially in less densely populated areas.
