In contrast, rainwater is simply filtered and disinfected using a UV light source. 

Not surprisingly, these processes result in water that tastes different, and while Australian tap water is amongst the highest quality in the world, you will often find families that drink rainwater say they prefer the taste to mains water, and once they’ve experienced rainwater, they don’t want to go back to mains water. In addition, because it is not subject to chemical treatment, many homeowners consider it to be a healthier and higher-quality alternative. 

You will need to ensure that you have a properly designed and well-maintained system, but by taking some simple steps you can rely on your rainwater harvesting system to deliver safe, clean, healthy, and fresh water than your family will love.
