CO2Sense Yorkshire is a business support and market development programme funded by Yorkshire Forward and the European Regional Development Fund. The investment will help David to manufacture and develop his Saver-Siphon device for distribution via a major DIY retailer.

The device has the potential to save billions of litres of clean water from being wasted. Toilets fitted with the Saver-Siphon only flush when the handle is held down – cutting water consumption by about half. For houses with water meters, the Saver-Siphon has the potential to cut household water bills by about 20% and save people about £67 a year.

Steve Ogden, CO2Sense project manager said: “The Saver-Siphon has the potential to have the biggest impact on domestic water saving of any new piece of technology in 150 years. CO2Sense has invested in David’s company, Varyflush, to help it take the device to the mass market. A major retailer is already interested in selling it and our investment has been matched by a manufacturer based in West Yorkshire, Zeta Plastic Components, who have taken an equity stake in the business. Zeta will make the new full siphon, which can be used on a much wider range of toilets including new ones. Funding from CO2Sense will pay for design and testing, developing the manufacturing and distribution processes.”
