Hippo Case Study - Haven Holidays

Written by Daniel Coward, Environmental Sustainability Manager, Bourne Leisure Ltd.

As the largest leisure and tourism holiday provider in the UK, we recognise the importance of our environmental responsibilities, using ‘only those resources appropriate to the task’; has become a company mantra and our organisational mission statement is centred on triple bottom line economic principles of people, planet and profit, a sustainable business who strives for sustainable growth. We constantly strive to improve the holiday experience in all ways possible while simultaneously managing our resource usage in ways that means the environmental impact of holidaying with Haven is minimised. So our guests need not worry about the impacts of their well earned leisure time and can relax in some of the UK’s most prime coastal destinations with peace of mind. Our environmental programme is wide ranging and in order to achieve long term reduction targets and guide the business into times of relative resource scarcity we created a road map of how to drive the business forward in a sustainable manner. During the early parts of this process we quickly identified the lowest hanging fruit, those projects that didn’t cost the earth to set up and provided superb paybacks. One of the retrofit products which worked very well and showed superb return on investment was ’Hippo the Water Saver’, we ordered 5,000 of these and introduced them into all of the older style toilet cisterns across the estate (ignoring post 2001 duel flush models). These toilets accounted for roughly 30% of water consumed per holiday home. We effectively reduced the water used per flush from 7.5 litres to 6 litres, achieving a reduction of 20% implemented easily and effectively in a way that didn’t compromise the effectiveness of the flush and unless you look into the cistern you would never know it’s there. We feel it is very important to tackle toilet water consumption as its such an easy win, provides great return on investment and you are saving valuable drinking water.”
