Dear Environment Agency,
Could you please supply details on how to calculate the size (capacity in Metres cubed) of a SUDS pond to support the surface water runoff from a new housing development upto a 1:100 yr return period.e.g. 450 homes covering an area of 22 hectares of previously Greenfield land (GFRO est 90.2L/s).
Thank you for contacting the Environment Agency.
