The saying ‘every drop counts’ has never been more important. That is why it is so important to have the capability to harness water from rainfall events. The best way to do this is by using a rainwater tank. Rain harvesting is an excellent method to save on your water bill whilst taking pressure off the water table.
To help calculate the size of water tank you would need to harvest adequate water, Bushmans has created a rainwater tank calculator that allows you to input your water usage details and find the right tank for you.
