1 Grosvenor Square, London
Active Attenuation System
Situated on one of London’s most iconic sites close to Buckingham Palace and marketed as Europe’s most desirable real estate, No.1 Grosvenor Square comprises 44 luxurious residences, a gym, 25m swimming pool, spa and cinema.
An Aqua-lity Storm Control (ASC) system utilises StormHarvester’s technology to turn the 125,000L rainwater harvesting tank into an active attenuation tank. The active attenuation tank is used to recycle water for reuse around the site while at the same time allowing the tank to count towards the sites overall storm attenuation requirement.
Installing the ASC system equipped with StormHarvester technology negated the requirement for a separate 125,000L attenuation tank on-site and therefore freed up space on-site which proved extremely beneficial as 1 Grosvenor Square is currently one of the most valuable pieces of real estate per m² in Europe. This also contributed significantly towards construction savings.
The ASC system insures a large reduction in the volume of stormwater discharged from the site into Thames Water’s local sewer network. Instead of being discharged the water is now reused on-site which contributes to reducing the site’s annual water bills.
