Southend Airport Stand Drainage

On behalf of Southend Airport Burroughs reviewed their existing drainage infrastructure in terms of discharge quality compliance and management of Glycol de-icing fluids. The project comprised the detailed assessment of contributing drained areas, active Glycol operations, system surveying and review of operational procedures. There was a concern regarding the potential of accidental discharge of de-icing contaminated surface water to SSSI rated receiving water courses, that the Client wished to pro-actively address.

A confined spaces entry survey to large underground attenuation tanks and penstock control chambers, addressing both dimensional concerns and asset condition was undertaken. Burroughs were involved in the appraisal of risk caused by the as-constructed drainage system and developed a low-cost solution to remove pockets of retained water within the network, therefore removing the potential for de-icing liquid to be inadvertently discharged during the following storm event. Burroughs lead the appraisal process working collaboratively with the client’s operational division.
