Total Water Solution

Rainwater harvesting is a simple and cost-effective way to collect and store water. In most cases you can easily divert your existing downpipes to fill one or more water storage tanks to help save money and make the most of a precious resource.

We will work out what you need and supply all the equipment for a rainwater harvesting system. Choose above or below ground storage tanks sized from 500L to 30,000L, screens that prevent debris from entering the water storage tank, and water purification treatments.

All large pre-ordered water tanks are delivered free to your home build. Some can be installed yourself, while others will require professional installation.

Once you have collected your rainwater, it needs to be filtered and pumped into your home. We'll figure out the right pump and pair it with a sophisticated filtration system. A UV steriliser kills 99% of bacteria and parasites with ultraviolet technology, which is eco-friendly and chemical-free. Next, scale, sediment, and rust, if necessary, are removed down to 1 micron. Then, water is ready for drinking and household use.

Household greywater can be filtered to nourish your lawn and gardens using the Watermate greywater recycling unit.

The Watermate Greywater Recycling System uses a simple but effective three stage filtering process to remove impurities such as hair, lint, soap and detergents, and the resulting water is ready for the garden.

If you're on a septic system, sending your greywater out for garden use keeps it out of your septic system, reducing the amount of soap and chemicals that can negatively affect its bacterial performance.
