Project Description

The Oracle Shopping Centre

Hammerson Plc, Reading

Following on from Hammerson Plc’s initiative to look at their current water consumption, Propelair were engaged to carry out a study of their toilets water usage at The Oracle Shopping Centre.

From the installation of 15 Propelair 1.5 litre toilets in March 2016, the trial was a success and 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.
