Giant Calmed Inlets

The DN150, DN200 and DN250 form the 3P range of giant Calmed inlets. For use in larger rainwater storage tanks, the inlets prevent disturbance of the settled layer of sediment whilst providing freshening oxygen to the water stored at the lower end of the tank.

The calmed inlet is designed to prevent water from staining and developing odours, and to ensure the best possible water quality.

How it works

  • Rainwater flows into the calmed inlet through a DN250 pipe
  • As the water flows through the calmed inlet, its velocity is reduced to allow it to enter the tank without turbulence
  • Calmed rainwater entering the tank supplies oxygen to the water resting at the lower end, keeping it fresh by prevention of anaerobic decomposition
