Storm water attenuation crates

For attenuation of storm or surface water storm crates must be wrapped in a damp proof membrane so as to hold the water. This method is designed so that you can slowly release water into storm drains with the help of a vortex valve, suitable if your local authority places limits on the flow rate of the water you plan to send to drains. It also works for smaller commercial projects or domestic projects as you can hold the water until it can be returned into a rainwater harvesting system.

For domestic projects that require a shallow dig, Graf Infiltration Tunnel weighs in at only 11 kilos so can be handled easily. If the tunnel will not taking any load bearing the minimum earth covering is just 250mm.
