Because every drop counts
Population growth and increasing water consumption is putting increasing pressure on water availability which could decline by as much as two thirds globally by 2050, posing global economic, societal and environmental threats. Greywater reuse exploits natural matching in domestic water usage – approximately the same amount of water is used showering or bathing as is used flushing a toilet over the course of a day. Cascade Water Products Ltd is developing Aqua Gratis’ a citizen-centred and integrated ‘hard’ waste water recycling system ensuing legislation and deficiency of the State of Art are met which when fitted into domestic and commercial new builds will:
- Help achieve SDG 6,7 and 9
- Reduce water consumption and make water supplies go further.
- Reduce damage to the environment cause by water abstraction and climate change.
- Significant role in the water energy nexus – making significant reductions in Water Company energy requirements for water production and sewage treatment and realise energy savings of ~23% and reduce annual CO2 emissions by 86tons per average EU household.
- Achieve sustainable water consumption through resilient product and promote water and energy saving Aqua Gratis is the core focus of the business and our strategy for future growth. The Duchy of Cornwall, Thames Water and Severn Trent Water recognises domestic greywater reuse has a significant role in future proofing its water supplies.
- By reducing domestic water consumption by more than 30% the beneficial impact filters through to infrastructure built to supply water and will reduce size of developments and costs.

Start of the journey
When Carolyn met Peter Holdsworth , she was a single parent of four boys. The teenagers were prone to taking long hot showers and she constantly knocked on the bathroom door calling out, “stop wasting water and energy”.
The seeds for this passion for saving water were sown during the long hot summer of ’76. Carolyn was 13, there was a drought and water restrictions. John Noakes and the Blue Peter team gave water saving tips.
This must have made an impression on her and meeting Peter Holdsworth, inventor and engineer, in 2009 sealed Carolyn’s fate.
Peter was working on developing domestic grey water reuse systems. Working with Ecoplay and building his own system, ReAqua, to capture the bath and shower water, using the greywater to flush toilets and recycling the heat back to the hot water tank.
Being a thrifty Scot, this seemed like a good idea to Carolyn.
It was after the UKTI representative for Houston, USA visited our tiny innovation stand at Ecobuild 2014, that she began to realise that saving water was not just a good idea but a global necessity.
Much has been learnt since then.
