Thames Water has just completed a trial of water saving toilets at one of their offices. They have replaced five existing toilets which used an average of 6.2 litres per flush with toilets from Propelair that use only 1.5 litres per flush. Combined with water sensors on taps and urinals, they have managed to reduce consumption by 606,000 litres per year, saving approximately £1,600 per year. Thames Water now plan to install the Propelair toilets in their three largest offices and expect to save 10 million litres of water and £10,000 per year as a result.
Installing replacement toilets can be very cost effective. All Propelair toilets are on the Water Technology List so attract tax relief under the Enhanced Capital Allowance scheme. Tax relief on the capital cost can also be claimed against Annual Investment Allowance. Finally, Propelair have a lease scheme which allows them to supply the toilet free of charge and use , using the monthly savings to pay for the installation.
