Fred Brownlees made this Freedom of Information request to Environment Agency

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was partially successful.

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).

Yours faithfully,
Bob Brownlees

To Bob,

 

Please find attached 2 detailed technical documents that can be used to
calculate Greenfield run-off rates and size of attenuation ponds.  There
is also another document that can help but it is too large to attach to
this email.  Try a Google search for SUDS Manual C697.

 

1.       Preliminary Rainfall Run-off Management for Developments

2.       Interim Code of Practice for SUDS 2004

3.       SUDs Manual C697

 

The above documents will all help calculate the figure you require

 

Regards

 

Paul
