Rainwater Harvesting Filters

Rainwater filters prevent leaves moss and other debris from entering the rainwater storage tank and reduce build-up of sediment. They can be bought as a kit or as separate component parts.  Kits B & C filter in two stages – large debris is removed initially through the cascades before the water passes through a finer second stage mesh:

  • Kit A – designed for roof sizes up to 200m2
  • Kit B – designed for roof sizes up to 450m2
  • Kit C – designed for roof sizes up to a max of 800m2

Each filter has two inlets, 2 x 4″ on filter kits A & B and 2 x 6″ on the larger filter kit C.  Filter kits B & C also have an overflow to remove the debris into a drain or soak away as well as and an outlet in the bottom of the filter for water to enter the storage tank. 

The filtered water enters the tank via a calmed inlet, filling from the bottom and thereby oxygenating the water and preventing it from stagnating. 

The overflow siphon, incorporating a skimming inlet, diverts any overfill or excess water to a drain or soakaway. By skimming the surface water further debris, pollen, oils and other floating contaminants are removed.

Rainwater harvesting tank filters can be fitted to new or existing rainwater storage tanks.
