Rainwater Harvesting
|
Why should we use rain water?
Water is part of a never-ending cycle. Between the seas, clouds, rain, hail, snow and the system of streams and rivers no
drop gets lost and no new drop is made.
However, saving fresh and drinking water makes sense from both an economic and an environmental viewpoint. Water may seem to
flow endlessly from our taps, but its delivery and purification requires more and more energy, more effort and so more expense.
Drinking water is our most important food. The average household uses around 128 litres of water a day, but as little as 3%
of it is needed for preparation of food and drinks.
For many uses we just do not need high quality drinking water. For toilet flushing, washing machines, for cleaning and
garden watering you can safely use filtered rainwater, with the help of the right rainwater equipment, properly installed.
This means that half of the drinking water used can be saved without any reduction in hygiene and comfort.
Other benefits of using rainwater:
1. More efficient washing, saving up to 50% on washing powder.
2. Washing machines do not become furred up with lime.
3. No limescale built up in toilets and urinals.
4. There is no better water for your garden and plant irrigation.
How does rainwater harvesting work?
Water is collected from hard surfaces such as roof areas. It is then fed through finely woven and self-cleaning filters
made from stainless steel which remove debris and unwanted substances from the water.
From the filter it runs into either an underground or an overground tank. The water is then pumped out of the
tank by a submersible pump for use in areas such as toilet flushing, washing machines and garden watering.
In the event of the rainwater running low a controller unit can be installed to top up the tank with mains water until the rainwater suply is restored.
