Snowhill Wharf, Birmingham
Active Attenuation System
Snowhill Wharf is the first flagship development from St Joseph, part of the Berkeley Group. This development is located close to the Colmore Business District (CBD) in Birmingham City Centre. It contains over 400 residential units, a gym, sauna, steam room and communal cinema.
The StormHarvester – Active Attenuation system was used to turn the 130,000L geo-cellular crate attenuation tank into an active attenuation tank. The active attenuation tank is used to recycle water and irrigate the extensive landscaped areas around the site while at the same time allowing the tank to count towards the site’s overall storm attenuation requirement.
Installing the StormHarvester system negated the requirement for a separate 130,000L rainwater harvesting tank on-site and therefore contributed significantly to savings within the drainage package. It also freed up some valuable space on an already cramped site.
The StormHarvester system insures a 98% reduction in the volume of stormwater discharged from the site. Instead of being discharged to the local sewer the water is now reused as part of the site irrigation system. This also provides significant on-going water savings to the development.
