How it works

  1. Water is equally distributed across the cascade
  2. Cleaning occurs through the cascades with the largest dirt particles forced across the primary filter cascades directly to the sewer
  3. Pre filtered water then flows over the secondary filter sieve (mesh size 0.65 mm), where the mesh structure washes any remaining dirt into the sewer
  4. Cleaned water flows into the tank
  5. Dirt goes directly to the sewer
