Wates Group, Leatherhead

As part of Project Dove, a major refurbishment of the Leatherhead offices took place in May 2016.

Propelair toilets were chosen to replace 27 standard toilets, increasing the buildings energy efficiency and water reduction, helping Wates win the Queen’s Award for Enterprise; Sustainable Development.

Through installing the 27 Propelair toilets, Wates can expect to save over 2.6 million litres of water.
