The results showed a £900,000 saving which is equivalent to 304 million pints.
Gavin Worthington, purchasing manager for Greene King said: “Whilst delivering an excellent financial result, we were particularly impressed with the expertise and market insight which the Waterscan team brought to the project.
“We now work together in partnership and have much better management of water in our business.”
The project has won the Water Efficient Project on the Year award at the 2015 Energy Awards.
In order to conduct the audit, Waterscan used an online water management system called Waterline which is designed to show performance.
The data is there to help identify the high consumption sites against site appropriate baseline.
Following this, sites can then be audited which helps to highlight issues as well as help to analyse risks plus shows opportunities for improvement.
As a result of using the latest technology and considering multiple scenarios, Waterscan “proposes optimum strategy in line with business goals and continues to monitor performance through Waterline system”.
The strategy was a first in pub and restaurant industry and included:
- Monitoring, management and maintenance of target
- Physical assessment of opportunities to reduce consumption
- Assessment and validation of the current position and baseline data
- Clear demonstration and reporting of reductions achieved
- Delivery of reduction through multi-faceted approach
- Clarification and definition of targets with agreed KPIs
A total of 149 audits of high-consuming pubs was carried out by Waterscan technicians.
The investigation showed that there were opportunities for better efficiency with the water.
The consultancy picked up on leaks on supply and internal pipework which was fixed, along with faulty water storage tanks which were repaired.
Urinal controls and toilets as well as shared supply and meter reading issues were all looked into.
Consumption across Greene King establishments decreased by 173,000m³ (12.13%) which is the equivalent to 304 million pints over three years against a 2012 baseline across this part of estate
Director of Waterscan Claire Yeates said: “Our approach for this project pushed the boundaries of traditional water management in the sector by setting targets for reduction and thinking holistically about all water associated risks.”
