Rainwater Harvesting

Flush lavatories, wash the car and even fill the washing machine

In the UK, rainwater has had something of a bad press lately. With news reports all-too-regularly showing apocalyptic scenes of flooded towns and villages, sand-bagged doorways and dispossessed businesses and homeowners, it is easy to forget the life-giving importance of water in our everyday lives.

Moreover, such plentiful rainfall (due mostly to global warming and climate change) makes many of us take water for granted. Instead of harvesting it and, in so doing, help to reduce our energy usage and water bills, we instead allow it to drain away via our drains and gutters.

Rainwater harvesting is a term given to the collection and usage of rain that has fallen onto rooftops and garages, etc. with a view to reusing it (usually) for non-drinking purposes. Gardeners and allotment-owners have been harvesting rainwater for generations and, in its simplest form, this consists of a simple downpipe system that redirects falling rainwater into a water barrel/butt for later use in dry periods.

However, what many of us don’t realise is that new technological innovations now make it possible to connect rainwater harvesting systems directly to our home’s existing plumbing and in doing so, save energy, since, as well as watering your garden, rainwater can now be used to flush lavatories, wash the car and even fill a washing machine. Although using captured rainwater for drinking purposes is still controversial (even with bacteria-killing water treatments), utilising rainwater for some non-drinking purposes has been shown to cut our water consumption (and our water bills) by up to 40% according to the Rainwater Harvesting Association.
