The University is working to reduce total water consumption and its associated demand on this scarce resource.
Reducing water consumption
Starting from a 2017-18 benchmark of 513,000 cubic metres, the University is challenging itself to reduce water consumption despite an expected increase in residences over this time.
This will be achieved through four streams of work:
- Detecting leaks: this is done through a combination of the installation of strategic meters, pattern analysis, increasing reporting and a range of other methods including the use of heat-vision cameras.
- Reducing consumption: through changes in equipment, behaviour and usage in both residences and academic buildings.
- Independent supply: our Stag Hill campus will be supplied from an onsite borehole, reducing costs and the energy required in transportation.
- Preventing waste: by installing intelligent controls and reducing flush and flow rates across campus, we are looking to reduce the amount of water that might be potentially wasted.
A number of successes have been identified so far:
- Existing systems are being monitored while we prepare the installation of additional meters over the coming months.
- Current behavioural patterns and consumption are being studied to establish the most effective areas to tackle first.
- The onsite borehole is in place and has been signed off by the Environment Agency, and initial test pumping has now been conducted.
- Stage one of preventing waste has already been completed with the instillation of passive infra-red systems across 26 bathrooms and more than 120 urinals. This has resulted in a saving of £33,000 a year and a staggering 22,000,000 litres of water a year, the equivalent to nine Olympic sized swimming pools worth of water.
