Varyflush Ltd. is a family-run, Yorkshire-based business that has been designing and manufacturing water-saving toilet devices for over twelve years. Increasingly aware of how much water is wasted through the toilet (the toilet is the appliance guilty of wasting the most water in any given household), technology teacher David Wilks set about designing a retrofit device that could be easily fitted on to siphons in standard, front-handled toilet cisterns, thus converting them into water-efficient appliances at very low cost. The idea that the amount of water used could be varied depending on the person’s need would provide a welcome alternative to the full flush or dual flush systems, both of which flush fixed amounts of water each time. Whilst designing the Interflush, David embarked upon a successful two-year campaign that changed national water regulations to legalise interruptible flushing in the UK.
David approached several water companies in the hope of securing a wide take-up for his technology. However, realising that water companies by and large are in the business of selling water, and not saving it, David turned his attention to the public sector. A successful trial was conducted by Leeds City Council in 2008, generating wider recognition amongst consumers of the benefits of interruptible flushing.
David was nominated as a Fellow of the Royal Society of Arts in 2007 and has also appeared on various television shows, including Dragon’s Den and This Morning. Today, Varyflush Ltd. supplies products to universities, banks, plumbing merchants, housing associations and various environmental groups across the UK and Ireland.
In the current climate – both economic and environmental – it is important to take steps to reduce the amount of monetary and resource waste that we have grown accustomed to in our everyday lives. By spreading the word about Varyflush Ltd. products, which are affordable and easy to install, we hope that people will begin to take responsibility for how much water they use, in turn helping to reduce per capita consumption for the benefit of society for generations to come.
