The Problem

The energy manager at this popular UK food chain had problems obtaining water data from many of her sites and wanted an easy-to-use dashboard which could automatically generate reports for her, the regional managers, and individual branch managers.

As well as indicating consumption, she wanted ways to prioritize water saving devices for high-waste branches, and automate efficiency measures by turning the water off during out-of-hours.

How did we help?

Using FlowReporter, she could see the realtime and monthly consumption rate of all her branches in one screen, order by efficiency, and send access to regional and branch managers.

What did we find?

At the very first restaurant which was installed, using the realtime graphs, we immediately identified that the site had a leak. By splitting the restaurant into zones, we could prove where it was coming from and how much it was costing them.

What was the result?

After fixing the faulty water softener, their water consumption dropped from around 4,000 litres per day to 2,100 litres per day – a reduction of almost 50%!

Alerts were also sent out whenever a tap had been intermittently left on overnight, where the average flow rate was 6,500 litres per day. Depending on the temperature of the tap, this would equate to an unbudgeted cost of between £8 and £50 per night. The future plan is to automate water efficiency measures by using FlowReporter to turn the water off out-of-hours so this waste will always be mitigated.


Continuous monitoring, coupled with automated alerts, is by far the best way to spot problems, minimise waste and keep bills low.

Just one restaurant in this chain saved over £2,000 per year! The energy manager can now keep on top of all the restaurants with automatic reports, and specific alerts which only go out to relevant branch managers.

A “default-off” water plan is also in progress to mitigate all future leaks which occur when the sites are closed.
