Winchester City Council

Winchester Guildhall

Propelair toilets have been installed at Winchester’s Guildhall. This has provided the council with substantial environmental and financial benefits.


Collectively an estimated saving of 762,119 litres will be achieved over the year. This substantial water saving is equivalent to the same amount of water required to run just over 9,500 baths.

Annually the toilets will use 273 Kg less CO2, translating to the same amount of carbon emissions generated in 475 cab journeys in central London.


Each unit is expected to save approximately £320.83 annually. During the 15-year life of the toilets, Winchester Council will save around £38,500.


Propelair also provides health and well-being advantages to the Guildhall’s staff, customers and visitors.

Every time a conventional toilet is flushed, sprays of contaminated water become airborne, landing on washroom surfaces. With Propelair’s unique air flush system, the spread of these airborne germs is eradicated – helping to prevent sickness amongst users and reducing unproductive absences.
