The first step of treating rain water is removing sediment and smaller organic matter from the water. 

Rain water is mainly captured by run off and along its journey it picks up sediment such as dust, leaves, sticks and dirt. 

Sediment and organic matter is captured in the preliminary filtrations methods of:

  1. Sand filtration
  2. Screening
  3. Cartridges

These filtration methods can be self-rinsing.

Ultraviolet Light Sterilisation

Uv light treatment is only effective after sediment has been filtered out and is paired with reverse-osmosis systems to remove bacteria such as E.coli and Giardia.

This is the most suitable rain water treatment system as water is immediately safe to consume and there are no additional chemicals that change water taste.

Larger scale rain water systems require chlorination for storage


For large scale projects where rainwater is stored for longer periods and where taste is not an issue, chlorination is the most cost effectivee treatment method.

Special sampling pumps automatically distribute the right amount of chlorine periodically to keep stored rain water safe and useable.

Where crops and livestock are involved it is not always suitable to use this purification method. Instead, an active sterilisation approach is designed into the rain water system.

Rain water systems require a pump to pressurise water delivery systems that draw on rain water tanks. Water may be used on large gardens, inside homes, pools and fish ponds.

With the addition of a small solar panel and battery this system becomes self-sufficient with electricity and water. 

The technology embedded in this rain water system set up is simple and improving all the time. Perth has one of the most suitable climates for this system where the number of sunny days to rain recieved means there is enough electricity to power the system throughout the year. 

Design & Location

Water tanks are cumbersome and cannot be moved once full.  For residential rain water tanks the best time to install them is during new builds. This way it is easy to place tanks underground and out of sight.

The best locations for new homes to install water tanks are under car ports, verandah and patios and even grassed areas.

For established homes slim line and semi-submergable tanks allow home owners to put them in less visible locations.
