  1. As rain water arrives the water level builds up, and overtops the filter lip, so ensuring it is distributed evenly across the whole with of the filter cascade.
  2. Pre cleaning through the cascades. Larger dirt particles are washed across the cascades directly to the sewer.
  3. Pre filtered water then flows over the secondary filter (mesh size 0.55 mm). Due to the special structure of the sieve mesh, any dirt is washed directly into the sewer which means the filter is self cleaning, low maintenance.
  4. Cleaned water flows to the storage tank.
  5. Dirt goes to the sewer.
