Project Description
The Princess Alexandra Hospital
NHS Trust
Following a successful trial, The Princess Alexandra Hospital in Harlow has chosen to refurbish all of its public toilets. Propelair technology brings substantial hygiene benefits, alongside increased flush efficiency which has added value by eliminating blockages in extreme high usage areas where issues had previously arisen on a daily basis.
“We were experiencing blockages nearly every day in one public toilet located outside maternity which was very heavily used. Since replacing this with a Propelair unit 10 months ago there have been no reported blockages. The women’s staff toilet used to block on a daily basis too, but this hasn’t happened since installing Propelair 4 months ago. The toilets work really well and offer savings not just on water but on maintenance costs and call-outs too.”
