Rainwater Harvester

Rainwater harvesting is one of the most natural ways of saving water.

Fresh water is an extremely limited and precious resource. In fact, less than 3% of all water on the planet is considered "fresh". During the 21st century, it is estimated that the demand for water is going to increase dramatically, to such an extent that the government is now looking at more sustainable approaches for water conservation.

A Rainwater Harvester captures and stores large quantities of rainwater for you to use in toilets, washing machines and in the garden.
More and more builders are finding that a rainwater harvester helps with planning permission, and makes houses more marketable. Systems are easy and quick to install.


How much water can be saved?
Households can expect to save up to 50% of their water consumption by installing a rainwater harvesting system. As the average person uses around 140L of water per day, you could save up to 70L of fresh drinking water per day per person:

  • Flushing the toilets
  • Washing clothes
  • Cleaning the car and other outside cleaning
  • All of the water needed for these can be met with filtered rainwater.

How big a roof do I need?

We recommend the tank size to go with your roof. A typical four bed house will capture enough water to keep a 5000l tank in use through most of the year.


What happens when the tank runs dry?
When you choose a system designed for flushing the toilets, there is an automatic switch over to using mains water so you can keep on flushing.


Is harvested rainwater clean?
With the "CS1" filter system unique to our harvesting systems, you get 95% pure water. This is more than good enough for flushing toilets and using in washing machines.


How will rainwater affect my washing machine?
Because rainwater is soft, it means you use less detergent for washing and it causes less damage to the heating element than hard water. This also means you create fewer pollutants which is good for the environment.
