Our proactive approach helps spot faulty equipment saving Esso £35,000 a year in charges.

Thanks to our proactive approach, we quickly investigated unexpectedly high water consumption and were able to identify that faulty equipment was to blame.

Gone undetected this faulty equipment would have cost Esso £35,000 in water charges over a year.

Esso began life in 1888 as the Anglo-American Oil Company. Today it is part of ExxonMobil Corporation with more than 1,100 service stations in operation in the UK.

Identifying unusual consumption

During a periodic review of customer accounts, we noticed that water consumption at one Esso petrol station was higher than expected, suggesting that they may not be getting the best value from their chosen tariff. This high consumption was particularly unusual since the garage did not have an active car wash on-site, indicating that faulty equipment may well be to blame.

Water efficiency audit

Our next step was to carry out an onsite water efficiency audit to try and identify the cause of the increase. The team’s water efficiency expert found that the car wash had not been decommissioned properly and was still using water. Once this was fixed it resulted in an almost instant drop in water consumption. In fact, water use fell by 47m3 a day leading to savings of £35,000 a year in water charges.

A winning combination

Our practical approach and technical knowhow were a winning combination, helping Esso to bring down their water consumption at the Bedfordshire site and saving them money. Now equipped with the knowledge of what their water use should be, the customer can monitor their future usage to ensure that these savings are sustained year on year. And we will be on hand to provide any further support and make sure the customer only pays for the water they need.

Alex Few, Esso Tesco Alliance Territory Manager, commented: “Anglian Water Business’s proactive approach assisted us in identifying and isolating water wastage on our site.”

“They have helped us to cut expenditure through reduced water consumption and to understand what our usage should be, such that savings can be sustained into the future.”
