Scottish Couple's Kitchen Table Idea Saves 45% Water Usage

What started as an engineering challenge at a kitchen table in Angus, Scotland has just earned £350,000 in funding to help solve the global water crisis one household at a time.

Carolyn Hogg and Peter Holdsworth spent more than ten years perfecting a system that captures water from showers and baths, treats it, and reuses it for toilet flushing. The result? Homes can cut their water consumption by up to 45% without changing daily habits.

The couple didn't just draw up plans and seek investors. They installed their micro-greywater recycling system in their own home over three years ago, where it's been running every single day since. That's over 1,000 days of real-world proof that the technology works reliably in everyday life.

The investment from European and American investors will help Cascade Water Products scale production and bring the system to market. They're targeting holiday resorts, hospitality venues, rental properties, and homes with private water supplies where water efficiency directly impacts costs and sustainability.

The timing couldn't be more urgent. Even water-rich Scotland has felt the strain recently, with Backwater Reservoir near Dundee dropping to just 43% capacity this past winter. That's less than half its normal level, highlighting how water scarcity is becoming a reality everywhere, not just in traditionally dry regions.

The Ripple Effect

Cascade's technology works for both new construction and existing buildings, making water conservation accessible to a wide range of properties. Self-builders seeking sustainable solutions now have a proven option, while commercial venues can see immediate cost savings alongside environmental benefits.

The system's beauty lies in its simplicity. Households don't need to ration showers or limit baths. The technology quietly does the work behind the scenes, transforming waste into a resource without asking anyone to sacrifice comfort.

Lead investor Mohan Ramani praised the Scottish company for doing "the hard yards" to prove their solution works. Cascade will showcase the technology at Future Build 2026, one of the UK's premier construction and sustainability exhibitions, where interest from the hospitality and housing sectors is expected to be strong.

After years of patient refinement and personal commitment, Hogg and Holdsworth are ready to share their innovation with the world.
