Concern with surface water flow over sports pitches in confined areas...

Today there is increasing need to control stormwater surface flow over levelled grassed sites. Suitable outfalls do not always exist in residential areas and so efforts are needed to attenuate this flow with the use of swales and temporary storage areas.

Reference to www.turfandgrass.com/s_articles/Restricting Drainage.php can be made for a more detailed account of attenuation in a local authority playing field complex.
