Holiday Inn, Plymouth

A visit from Shaun Dodd, a water efficiency auditor from Source for Business to the Plymouth Holiday Inn, in March 2011 was the start of substantial money savings for the hotel

As part of the initial inspection, Shaun identified that although the hotel’s plumbing was in good condition across the site, there were a series of simple improvements identified, which if made could account for worthwhile savings in just a few months.

For a hotel the size of the Holiday Inn, one of the higher water usage areas is the toilet facilities. With over 200 toilets across the hotel - this was identified as a priority area where water usage could be reduced immediately. At the time of the audit the majority of toilets were flushing at 9 litres per flush – the standard rate for a cistern installed before 1993.

As part of Shaun’s recommendations, the hotel was advised to install a cistern displacement device – otherwise known as a Hippo or Save-a-Flush – to all toilet cisterns, instantly saving 2.5 litres per flush, which on average resulted in a staggering 34,000 litres saved per week. What was even more satisfying for hotel manager, Willem Hamel, was that 233 Hippo and Save-a-Flush devices were given free as part of the audit, and he could see the savings beginning to add up, as soon as the devices were fitted.

Other recommendations identified to save water across the site, included covering the hotel’s swimming pool when not in use to limit evaporation, adhering to the service schedule for washing machines - only using with a full load, installing passive infrared controls to urinals and reducing flow rates to basin taps.

David Roberts, head of business development at Source for Business explains: “Holiday Inn Plymouth is a great example of a business which is already actively committed to protecting the environment and has the desire to reduce usage and costs. The hotel already operates an efficient system, however, the team identified areas where further substantial savings could be made – over 3,100 cubic metres per year – equivalent to one and a half Olympic-sized swimming pools.”

Willem Hamel, general manager at Holiday Inn Plymouth, added: “As a large hotel with 211 rooms, seven conference suites plus our panoramic restaurant and several bars, we were very aware of our water usage and keen to reduce the amount of water we used across the hotel without impacting on the service we provide to our guests and facilities for team members.

“Following the advice given as part of the audit last year, we have reduced our water consumption by 13% which equates to a saving of more than £13,500 over the year. It was a very useful exercise with fantastic results for our hotel.”
