Twinstore, the new type of stormwater tank from Tubosider UK that can deliver not just greater performance but at lower cost  than conventional systems, has now been awarded a UK Patent (no. 2461142).

Tubosider is the leading manufacturer of stormwater attenuation and drainage systems in galvanised corrugated steel, and developed Twinstore two years ago to beat cellular systems through its greater compactness. Besides winning on space, it also has the benefits of structural integrity and easy access for maintenance.

By balancing the ratio between tank and granular backfill and releasing water through pipe ends into a bed lined with an impermeable membrane, Twinstore reduces the overall excavation and cost. The system has been used on a wide range of major projects by contractors who are repeating its success elsewhere.

Twinstore is one of a range of stormwater attenuation and drainage solutions it designs and manufactures as fully prefabricated systems, incorporating any required accessories such as pumping stations, flow regulators, separators and check valves.
