Construction/Installation Details: BMS designed, manufactured, supplied and installed the full 868 m3 installation, with the client supplying the geomembranes.
Operation/Maintenance Details: BMS Stormbreaker installations are designed to be maintenance free, which is an important consideration considering the 50 year lifespan of most attenuation systems. More details can be found in the Stormbreaker Agrement Certificate or by contacting BMS. Furthermore the BMS Stormbreaker is by far the strongest plastic attenuation system available worldwide which gives peace of mind against system creep, subsidence or collapse.
