Underground drainage systems are used in gravity drainage and sewage installations. JDP provides a range of products suitable for foul and surface water drainage systems including pipes, fittings, chambers and test equipment.
Underground drainage pipes, often referred to as sewer pipes, plot drainage or house drainage, typically use 110mm drainage pipe and fittings. For larger capacity use JDP’s 160mm drainage pipe and fittings.
For more information on fitting underground drain pipes, please see our installation and principles article.
110mm and 160mm orange/terracotta PVC-U pipe is often used in the UK for house drainage and sewer systems up to the sewer main where sizes can increase up to 300/315mm, and even up to 600/630mm in some systems.
