The following case studies show the different approaches our Water Champions have taken to increase water efficiency and reduce their water and energy bills.
Did you know that making savings in the amount of water you use in your business can lead to substantial financial savings in your annual water bill, increase profits and benefit the environment?
There are a number of ways to become more water efficient, such as replacing old leaky pipes and equipment, raising awareness amongst your staff and improved monitoring of water use. We hope the following case studies will provide ideas for your own Water Champions action plan.

Sainsbury’s has been awarded Water Champions status after it made a number of water efficiency measures. Sainsbury’s has adopted a ‘Respect for Our Environment’ philosophy, with the aim of becoming the UK’s greenest grocer through a commitment to do the right thing for the environment. Twenty commitments were outlined and in order to meet this aim, Sainsbury’s ‘20x20 Sustainability Plan’ was devised. It set an initial target to reduce water usage by 50 per cent per m2 of sales area across the estate by 2013/14 versus a 05/06 baseline which was successfully achieved. Sainsbury’s commitment to being a Water Champion has been recognised by the company being the first retailer to have been awarded the Carbon Trust Water Standard and winning the Energy Efficiency through Water Management Award at the Energy Awards 2013. Water efficiency steps taken by Sainsbury’s include:

The City Hotel, a large four star hotel on the banks of the Foyle, reduced its water consumption by 18 per cent over a six year period. This was despite adding twelve new bedrooms and high visitor numbers during the UK City of Culture celebrations.
It did this by carrying out a review on energy usage within the hotel. This included reviewing water consumption because a large portion of its energy costs were tied up in heating water. It discovered that staff didn’t realise that the hotel paid for water because they didn’t pay a water bill in their own homes. To save water and save money the City Hotel:
- Ran an education campaign to inform staff of the benefits of saving water;
- Appointed an environmental champion in the hotel and a Green Team made up of staff from each department;
- Trained staff in environmental policies and what to do if they spotted a leak;
- Fitted energy saving showers, restrictors to taps and hippo bags in cisterns in all the hotel bedrooms;
- Fitted restrictors to the public urinals to reduce wastage of water;
- Installed a new water efficient dishwasher;
- Installed its own water meter in the yard and recorded daily water usage because the main meter was inaccessible;
- Placed a water pyramid in every hotel bathroom giving facts on how to save water;
- Promoted the ‘bag it and bin it’ campaign to highlight to guests what can and can’t be flushed down the toilets to prevent blockages and damage to the sewers; and
- Installed a water butt outside for washing down the yard.
- Financial savings of over £18,000 per year off the water bill alone;
- Further potential savings off its energy bills;
- Reduced water consumption through increased awareness;

Location: Near Coleraine
Gateside Farm near Coleraine is a 130 acre mixed farm run by John and Rhonda Lynn. It was the first farm to receive the ‘Water Champions’ accolade.
When John took over the farm in 2006 he found that it had a very old, disjointed water system. It had four roadside water meters and the pipe system consisted of a mixture of very old metal pipes and different sizes of plastic pipes. It also had old baths for water troughs which were a continual source of water leaks and needed regular maintenance.
To save water John:
- Installed a new water supply system and 20 new concrete drinking troughs;
- Mapped the location of the new pipes and noted the location of all new joints; and
- Initiated weekly recording of water consumption, livestock numbers and rainfall.
- Financial savings due to reduced leakage rates;
- Easy monitoring of water usage;
- Easier maintenance of water equipment; and
- Quick identification of location of pipes to easily find and repair leaks.
