Posted by Everyday we consume around 280 litres of water and it seems that more and more of us are taking water for granted. It is easy to think we will have an endless supply of water but without careful management our precious water could be gone before we know it.
This is why we need to implement water saving strategies like rainwater harvesting to ensure we recycle any water possible. This process collects the water that would otherwise go down the drains, go straight in to the ground or simply evaporate and allows us to reuse it in the home or garden.
The water harvesting systems can be installed in new and old buildings and can provide an average size home with 100m3 of water a year. So the water saving system saves around eight showers of water a day. The water saved can, not only be used on the garden, but can be used to flush the toilet, give water to the washing machine etc.
The tanks tend to be large, around 1,000 and 9,000 litres and most of the time are stored underground. Rainwater harvesting tanks are connected to the house and outdoor taps by a separate pipe network. The system works by using the tanks water, and when it falls below a certain level it will switch back to the main water supply.
Although this process has significant water saving environmental benefits, it can be quite expensive and the initial set up cost is a big put off. Setting up the basic system can cost between $1,000 and $3,000 and the excess costs of plumbing and fitting. But this harvesting system will provide long term benefits, providing around 30% of the homes water use.
