storm water storage cratesWhether you’re looking for filtration or attenuation storm water storage crates from leading brands are available from just £86.69 per m3 ex VAT from Drainage Superstore. The lightweight storm and surface water management systems can be easily assembled and installed beneath domestic and commercial or industrial buildings. Storm crates are easily installed in up to 10 layers, with a 95% void ratio, so an effective system can be achieved with a small number of crates.

Storm water filtration crates

Filtration can be achieved with storm crates from the likes of DYKA, Polypipe and Brett Martin with the addition of a geotextile. If you’re looking to return any storm or surface water into the natural environment simply wrap the modular crates in a geotextile to allow for gradual soakaway.

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.
