Water Champions Case Studies

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.



Type: Business Services 
Location: Belfast

Glandore provides serviced offices for a variety of customers. The team at Glandore worked with the Consumer Council to reduce their water consumption by making simple and low cost changes to the existing infrastructure, and changing their approach to managing water use.  This included:

  • Completed a water health check of the premises;
  • Installed sensor operated urinal controls;
  • Quickly repaired running toilets and taps;
  • Carried out regular servicing on filtered water taps;
  • Put in place a water risk management plan;
  • Sought advice from the Consumer Council on reading a water bill and reducing consumption;
  • Installed pulse action shower heads in the in-house showers ; and
  • Took regular readings of water meters and cross referenced these with bills.


  • This smart, simple approach has led to savings of about 7,000 litres of water or £20.00 per working day; and
  • Typical daily consumption per person is less than 50 litres.

Coca Cola Hellenic Northern Ireland


Type:  Beverage Industry
Location: Lisburn, Co Antrim

Coca Cola Hellenic Northern Ireland based at Knockmore Hill, Lisburn has the capacity to produce 1.5 million litres of beverages each day. Water is sourced mainly from boreholes as the company strives to reduce the amount of water required from the mains supply.  The company has excellent water stewardship credentials, both internally in terms of production processes and externally at community level. This commitment to water stewardship led to Coca Cola’s listing as a world leader in sustainability by Dow Jones Sustainability Indexes for the sixth consecutive year. The company has been awarded Consumer Council Water Champion status having taken the following water efficiency steps:

  • Water meters are included on all sources and regularly calibrated.
  • Water meters are regularly monitored to quickly identify leaks.
  • Monthly water use targets and a long term 2020 water target have been set to continue to strive for water consumption reductions where feasible.
  • There is a strong emphasis on measurement; water use is monitored in a ratio based on how much beverage is produced.
  • Water re-use projects have been implemented such as rinse water from the bottle washer being captured and used again in the case washer.
  • Sensor taps have been installed in the hand washing facilities and sensors on the toilet flushing facilities.
  • The line lubrication was changed from wet to dry or semi-dry to save water.
  • Workplace environment champions were appointed who carry out water audits to identify opportunities for water reduction/re-use.

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:

City Hotel Derry


Type: Tourism and Leisure Industry
Location: Derry

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;
  • Shows the public the hotel is serious about helping the environment;
  • Early identification of leaks through regular meter readings; and
  • Increased awareness motivated staff to raise £1,000 for WaterAid.

Gateside Farm

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;
