WHAT IS GREYWATER?

Greywater recycling is often confused with rainwater harvesting – but the two are very different. This is the reuse of water that has been used for showers, hand washing and washing machines. It can’t be simply used around the home like rain; it has to undergo a process of cleansing in order to be useful. In most domestic cases, the water from the aforementioned outlets is channeled to a treatment unit where it is filtered and disinfected. Once it has undergone this process it can be sent to a storage unit and linked up to WCS around the home. In general terms, daily supply per person will roughly equate to demand. While not as popular as rain collection, greywater can boost your home’s sustainability credentials, reducing your mains use and therefore minimising your home’s environmental impact. There are a number of specialists in the UK such as Aquaco (www.aquaco.co.uk), Aqulility (www.aqua-lity.co.uk) and WTS (www.watertreatmentsesrvices.co.uk).
