BS 5911-3:2010 Concrete pipes and ancillary concrete products. Specification for unreinforced and reinforced concrete manholes and soakaways (complementary to BS EN 1917:2002)
BS 5911-3 is a new standard that complements BS EN 1917 and is for use in conjunction with it.
BS EN 1917 specifies requirements and describes test methods for precast concrete manholes. It covers concrete manholes of circular, rectangular (with or without chamfered or rounded corners) or elliptical cross-section. It also covers unreinforced, steel fibre and reinforced manholes, with nominal sizes or nominal lengths not exceeding DN 1250 or LN 1250.
BS EN 1917 helps to permit access to, and to allow aeration of, drain or sewer systems for the conveyance of sewage, rainwater and surface water under gravity or occasionally at low head of pressure. These are mainly installed in areas subjected to vehicular and/or pedestrian traffic e.g. roads and pavements.
BS 5911-3 specifies complementary requirements to those in BS EN 1917 for unreinforced and reinforced concrete manholes. Full requirements for unreinforced and reinforced concrete manholes with nominal sizes greater than DN 1250, but not exceeding DN 3000, are also specified. The manholes are to be installed in carriageways of roads (including pedestrian streets), hard shoulders and parking areas for all types of road vehicles, though provision is also made for units subject to lighter traffic loading. Requirements for soakaways, landing slabs and corbel slabs are also specified in this standard.
BS EN 752, BS EN 1295-1 and BS EN 1610 deal with the planning, design, installation and testing of drains and sewers.
This version of BS 5911-3 replaces BS 5911-3:2002+Amendment 1:2004, which is now withdrawn.
