Wates Group reduces building water use by 87%

Since switching to Propelair, the construction company has saved huge amounts of water and energy

In the four years since Wates Group, a family-owned construction group in the UK, replaced its standard toilets with Propelair’s water-efficient toilet, Wates reduced water use by 87% at its headquarters.

Wates installed Propelair toilets in its Leatherhead office in May 2016.

Since then, the company has improved its building’s efficiency and significantly reduced its overall water usage, by around 5.3 million litres each year. To put this into context, this is as much as filling a bathtub 51 times every single day of the year.

This water saving has also lowered the group’s carbon footprint:

Compared to before, Wates is now saving 5,538 kg of carbon every year. That is as much energy as using 226 propane cylinders for barbeques, or about 13,700 miles driven by car.

Besides the environmental benefits, Wates has also benefitted from operational savings in cost: the 27 Propelair toilets have paid for themselves in just 2.7 years.

Dr Zainab Dangana, who manages Wates Sustainable Technology Services, said:

Wates is committed to becoming a zero-carbon organisation by 2025, and using innovative technology like Propelair, is an important part of helping us reach that target. Propelair is now one of 42 Innovation Partners featured in our WIN Portal, an online, free to use, innovation portal to boost the transition to net zero.” She added:

“Toilets usually consume more water than anything else in an office. So Propelair toilets were installed, replacing all conventional toilets in our head office and have reduced our water consumption by 87%. They helped us cut our water and sewage bills, too. Plus, our washrooms now present a lower infection risk from germs and viruses.”

The savings and benefits have been so significant that Wates plans to use Propelair toilets in other buildings and construction projects in future.
