Rainwater harvesting is not a new concept; it is an ancient practice. It is a technique that collects and stores rainwater for irrigation, laundry, toilet flushing, pool top-up, wash bays and as an off-grid/alternative supply of water. In some areas it is still the only supply of water. Rainwater can be collected from various hard surfaces such as rooftops and/or other man made above ground hard surfaces. Rainwater harvesting is growing in popularity due to an overall interest in reducing the consumption of potable water and the inherent qualities of rainwater. Unfortunately urban living, population increase, climate change, failing infrastructure, pollution, our lifestyles (to name a few) are all contributing to a worldwide water crisis. It is actually really very simple; our demand exceeds our supply and to sink another borehole isn't the answer; we are busy depleting our groundwater supply. To secure a future with enough water we have to save water; we have to harvest rainwater, because:
- It is a natural resource and reduces flooding, storm water runoff, erosion and contamination of surface water.
- It reduces the need for purchasing bottled water.
- It is an excellent source of water for irrigation
- It is relatively simple to install, depending on the application.
- It reduces your water bill.
- It supplies water during water outages.
- It promotes water and energy conservation.
The best part is you don't have to change your lifestyle; you don't have to start sharing showers and/or baths and you definitely don't have to shower in a bucket. Life can continue as usual whilst saving water. Always remember "Prevention is better than cure".
Harvested rainwater can be used for many applications.
