Pressurised mains (Dutch: drukleidingen) are components of pressurised sewer systems. Small small pressurised systems (Dutch: drukriolering) connect detached houses at long distances from a gravity system to the gravity system. Large pressurised systems (Dutch: persleidingen) consist of pressurised pipelines of large capacity that transport water from a gravity system to a wastewater treatment plant or between subcatchments of a gravity system. The pressurised mains are predominantly made of HDPE or PE. Storage and Settling Basins or Tanks (Dutch: bergbezinkbassins) are placed behind combined sewer overflows to provide extra storage capacity, contain pollutants and limit the frequency and pollution content of combined sewer overflows. With careful design the tanks are able to contribute nicely towards improving the surface quality. Storage and Settling Basins are usually designed as closed basins, especially if they are installed close to buildings. The basins are usually made of concrete. 2.6 Concepts, def initions and abbreviations In this paragraph a list is given with the most important concepts and abbreviations in the sewerage field. The terms in bold are defined just as in the NEN 3300: ‘Buitenriolering; termen en definities’ (Drains and sewers outside buildings; terms and definitions’). In addition, a list of these with the technical terms found in English, French and German literature is provided.
