Detention pond definition
Approved Document H - Drainage and Waste Disposal, gives the following definition:
'Detention ponds are used to attenuate the flow from a drainage system, to limit the peak rate of flow into a sewer system or watercourse. Further information on design may be found in the references given in paragraph 3.36 and in Sustainable Urban Drainage Systems – A Design Manual for England and Wales published by CIRIA.' (This has been superseded by The SUDS manual (2011 reprint with errata), 2007).
Paragraph 3.36 suggests that the requirement can be met by following the relevant recommendations of:
- BS EN 752-4 Drain and sewer systems outside buildings; Part 4 Hydraulic design and environmental considerations, clauses 3 to 12 and National Annexes NA, NB and ND to NI. (Withdrawn and replaced by BS EN 752 below).
- BS EN 752 Drain and sewer systems outside buildings.
- BS EN 1295-1:1997 Structural design of buried pipelines under various conditions of loading. General requirements.
- BS EN 1610:1998 Construction and testing of drains and sewers. (Withdrawn and replaced by BS EN 1610:2015 Construction and testing of drains and sewers).
