Maturity stage TRL 9 / CRI 3-4 - Commercial Scale Up / Multiple commercial Applications

F-Reg solutions specialize in the dynamic management of sewage networks, with the aim of combating flooding and waste dumping in cities caused by heavy rainfall. The flovalv, a solution patented by F-Reg, makes it possible to use sewer pipes as a storage area to regulate peak flows of stormwater and thus limit the damage caused by overflows. F-Reg solutions therefore represent an economic and environmental challenge for local authorities. Economical, because our solutions are much less costly than the creation of retention tanks and the purchase of land, and environmental, because they help reduce urban flooding and the discharge of waste into natural landscapes.

The Environmental Benefits

  • Each km of a sewage network can usually become a buffer storage of 100 m3 of sewage water during a rainfall
  • A 800mm valve can store up to 40 m3 of water
  • Implementation in 1 year instead of 10 with a retention tank
  • Limiting and reducing the risk of flooding in urban areas
  • Limitation and reduction of waste discharges into the environment (200,000 m3 of pollutant discharges avoided)
  • Reduces the carbon footprint of the heavy work required to create retention basins, as well as the destruction of land. (1,200 tonnes of CO2 emissions avoided)

The Financial Benefits

  • From 200 to 600 €/m3 with F-Reg Floval solutions (> 1500 €/m3 for retention tanks)
  • No land use required (each valves saves an average of 25 m2 of land)
