Innovative solution: Greywater

Can a greywater system reduce your bills?

From making cups of tea to using the dishwasher – we all have a responsibility to reduce our water consumption. On average, a single person uses around 80-100 gallons of water per day. This figure can be massively reduced just by installing a greywater system.

With the growing population surviving on a limited water supply, it is essential to save water (and money) where possible. So, should greywater systems be more commonplace?

50 shades of grey (water)

Greywater is waste water that comes from baths, hand-basins and washing machines etc– the relatively clean water that stems from a stream without contamination.

If collected and stored correctly, with minimal treatment, rainwater can be used for watering the garden and toilet flushing – potentially cutting household water usage by up to 50%.

As a result, grey-water recycling is one of a number of water solutions that we should look to in order to decrease our usage. Some systems can save 50,000 gallons a year! The more water that an individual uses, the more grey-water you will be able to recycle.

The two major benefits of grey-water use are:

  • Reducing the need for fresh water. Saving on fresh water can significantly reduce household water bills, but also has a broader community benefit in reducing demands on public water supply.
  • Reducing the amount of wastewater entering sewers or on-site treatment systems. Again, this can benefit the individual household, but also the broader community.

Water that has been treated can be put to good use. Tasks such as watering the garden and flushing toilets. This makes water consumption better for the environment as it is using less ‘fresh’ water than it normally would. As less water is needed, it reduces demands on public water supply, and, if recycled properly, it can save approximately 70 litres of potable water per person per day in a domestic household.

Are you wasting your water?

Greywater carries the risk of some pretty serious water-borne diseases if not managed properly. When stored, bacteria in the water can multiply, so it needs to be treated, like it would by water companies on a larger scale. Ensuring the right mix of chemicals and making sure you’re managing it properly is an ongoing job. Recycling grey-water makes sense from an environmental point of view; however, it may not be suitable for smaller families regarding the initial cost and maintenance.

In addition, if your house is metered, recycling greywater can significantly reduce the volume of water you use thereby saving you money on your water bills.
