What Are Grey Water Systems?
The water used in UK homes is clean drinking water (known as potable water), which generally comes in through the mains and exits through the sewer. Fifty to eighty per cent of a household’s wastewater comes from baths, showers, washing machines, sinks and dishwashers. This is referred to as grey water.
It’s called grey water because usually, it has no contact with human waste, unlike toilet water, which is known as black water. This makes greywater easier to treat and recycle, as there is no faecal matter involved that can contain harmful bacteria and disease-causing pathogens.
If greywater is recycled properly, it can save approximately 70 litres of water per person per day in domestic households. Therefore, greywater recycling systems are one of the best ways to decrease water usage.
How Does Grey Water Recycling Work?
Grey water is never going to be safe to drink, even when treated. However, recycled water may be used to flush toilets, wash clothes and water your garden.
It’s important to reduce the amount of drinkable water we use for things that don’t require fresh water. If we can use treated grey water instead, we’ll save more potable water.
A grey water system filters water, removing dangerous bacteria so it’s safe to use. There are various different systems you can use to treat grey water, and they vary in complexity. Once treated, the water is linked back to the desired appliances for use, thus saving potable water.
A new greywater system will vary in price depending on the system you wish to use, but like all recyclable solutions will definitely save you money in the long run.
