What is a harvesting system?

A rainwater harvesting system consists of:

  • Filtration
  • Storage Tanks
  • Pumps

Filtration

Filters are used to remove debris from the rainwater.

Filter Diagram
  1. As rainwater arrives, the water level builds up until it overtops the filter lip, providing equal distribution across the full width of the filter cascade.
  2. Larger debris is removed by the filter cascade and washed downstream with a small amount of rainwater.
  3. Pre-filtered water falls through the filter cascade and flows over a secondary filter sieve (mesh size 0.55 mm)removing the finer particles. Due to the special structure of the sieve mesh, any dirt is washed directly downstream making the filter self cleaning, with minimal maintenance required.
  4. Cleaned water flows to the rainwater storage tank.
  5. Dirty water flows downstream.

Storage Tanks

RainKeeper Potable Water Cistern

The polyethylene tanks are used to store your captured rainwater for later use. They are manufactured using resins that meet FDA specifications to ensure safe storage of potable water. These tanks also carry a lifetime warranty.

Pumps

Submersible Pump with Floating Inlet

Pumps are used to move the captured water from your storage tank to the point of use.
