GRP Preformed Tanks
These GRP preformed tanks are made off site ready for installation in a concrete surround. As well as Attenuation Tanks, Rainwater Harvesting Tanks can be used as part of a SUDS solution, see the Water Recycling section in our Commercial, Public & Industrial Buildings Specifier.

GRP Attenuation Tanks Range
In-Line Attenuation Tanks
In-line systems are designed to allow water to back up through the tank, and drain by gravity through the separate GRP chamber, housing a vortex flow regulator, or within the balancing tank itself.

V2: Vortex Control Tank Systems

Off-Line Attenuation Tanks
Off-line attenuation tanks have a flow regulator in a separate chamber, and so allows water to build up and even overspill into storage tanks to cope with even the worst of situations.
V3: Off-Line System
