Moir Environmental: Case Study
< Back to Moir Environmental's Profile

North Ayrshire

Client: Commercial Waste Management Contractor

A 700 m2 Retention Pond was installed in 2008 to treat the surface water runoff from approx. 0.80 ha of yards and 0.20 ha of roofs at a commercial waste management facility in North Ayrshire.

Features - The pond was designed specifically to treat dirty surface water runoff from a large concrete yard.  The yard has lots of heavy traffic movements daily and contamination with soil particles is significant.  Runoff is first settled in several Silt Traps prior to entering the Pond.  The treatment capacity, safety, biodiversity and amenity value of the pond are all enhanced by a wide margin around the pond which is planted with reeds.

Benefits - This type of surface water runoff treatment system is suited to sites where the treatment of runoff is required to protect the quality of a nearby watercourse.  The system provides the added and inherently designed benefits of flood alleviation by attenuating the runoff and habitat creation for wildlife.
