Project Description

The Oracle Shopping Centre

Hammerson Plc, Reading

Following on from Hammerson Plc’s initiative to look at their current water consumption, Propelair carried out a water usage review at The Oracle Shopping Centre’s toilets.

We started with 15 Propelair units in March 2016 as a proof of concept. The savings were so big that a further 28 Propelair units have been installed.

The Propelair toilet is a suitable choice for this high-usage site due to its huge cost saving benefits along with reduced environmental impact and easy maintenance design.
