An international day to celebrate freshwater was recommended at the 1992 United Nations Conference on Environment and Development (UNCED), and since then World Water Day has been held annually on 22nd March. The day aims to focus attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.
Each year, World Water Day highlights a specific aspect of freshwater. In 2013, in reflection of the International Year of Water Cooperation, World Water Day is dedicated to the theme of cooperation around water, which is very in keeping with what the International Tourism Partnership (ITP) has been doing on the topic of water since establishing a Water Working Group in 2012.
ITP is currently working with its 16 global hotel company members to address how the industry should address water challenges. This collaboration is being conducted through a working group on water, with its first objective: To produce a risk analysis of key water issues - present and forecast - of water availability and quality, along with an assessment of any cost and regulatory implications, in selected geographic regions, in order to increase awareness and understanding of how and where water issues present a significant risk to the industry’s future.
As part of this working group, ITP has engaged the help of SIWI, the Stockholm International Water Institute, to conduct a research piece on the above. More details of this research will be publicly available in early summer. However, for now, we’ve updated our practical Know How Guide to Water Management in the hotel industry...
Why the need to conserve water?
Water scarcity is a recognised global problem, with demand for water projected to exceed supply by 40% by 2030. By the same year, half the world’s population will be living in areas of high water stress.
Most water (97%) is in the oceans, which cover 71% of the Earth’s surface. 3% is freshwater, two-thirds of which is tied up as ice in glaciers and at the poles. This leaves approximately 1% as freshwater in rivers, lakes, the atmosphere and in groundwater.
However, with demand rising rapidly due to a growing global population with expectations of higher living standards and resource-intensive farming, that 1% is under threat. Climate change is adding to the problem because our weather patterns have become less predictable and more pronounced. While a number of areas are experiencing periods of prolonged drought, the rain that falls in some other areas is heavier. This leads to flooding without sufficiently replenishing groundwater stocks.
Hotel companies have both a strong commercial and moral imperative for addressing water use. Cost is a clear factor: water accounts for 10% of utility bills in many hotels. Most hotels pay for the water they consume twice – first by purchasing fresh water and then by disposing of it as waste water. According to the UK’s Environment Agency, depending on their water efficiency, hotels can reduce the amount of water consumed per guest per night by up to 50% compared with establishments with poor performance in water consumption. The moral reasons are equally compelling: water is a scare resource in many resorts around the world so hotels have a responsibility not to use more than necessary; in rural or remote areas it ensures that local residents are not deprived of their essential supply; and by reducing the amount of waste-water that needs to be treated, this lessens the risk of water pollution.
According to the latest research conducted by SIWI, almost 20 % of the world’s population live in areas of physical water scarcity. A water scarce region is one where water resources development is “approaching or has exceeded sustainable limits” and “more than 75% of river flows are withdrawn for agriculture, industry, and domestic purposes”. By 2030, the world might face a 40% global demand/supply gap of accessible, reliable water supply for economic development. The private sector is a major water user and often completely dependent on water for production and service delivery. The Hospitality industry is one of these where water plays a determining part in everyday operations and potential growth.
Water efficiency: Establishing a water management plan
In order to set up and achieve relevant and realistic targets you will need to invest time and resources in careful planning, organisation, training and follow-up.
The first step to take when creating a water management plan is to start measuring water consumption and set some tangible targets. It’s vital to know your start point and find out how much water you are currently using. Installing meters and taking regular readings will aid this and sub meters will help you see where the areas of greatest use are. These are obviously the areas where you will probably need to focus most of your efforts.
Another key part of understanding measurement and target setting is knowing your water costs. Work out what your potential cost savings may be and the payback period for any capital investment. Grounding a water management plan on costs, as well as environmental saving, will help gain the buy in of key stakeholders and improve your property’s overall efficiency.
Once measurement and targets have been set, you can establish a water conservation plan. Here are some suggestions of how best to go about this:
Moving through areas of a hotel where water consumption is likely to be highest, here are some ways in which you can change your operational water use. Always test first to see that any measures taken will not compromise quality, health or safety.
Having a swimming pool can increase fresh water consumption in a large hotel by up to 10% so think hard about whether it is really necessary before installing one. These steps will help ensure no water is wasted.
Water efficiency systems
Because of the separate pipe-work involved, grey water systems are expensive to install and chemical treatment of the recycled water is sometimes necessary for health and safety reasons (only in on-demand systems). They are therefore best designed into the building at the outset, although increasingly hotels are choosing to retrofit them because of the savings to be made. Payback time is difficult to calculate, as it will depend on the type of systems installed and the relative cost of the potable water to that of the reuse water. The payback can be anything from two to fifteen years depending on the cost of water at your location
Adjustable flow restrictors on taps enable them to deliver a lower instantaneous flow rate than screw-operated taps and can reduce water use by over 50%. Similarly, low-flow shower heads cost very little and use around 9.45 litres a minute compared with conventional heads (which typically use nearly twice that). If properly designed they should feel as effective as higher water volume models.
An IHG property recently experienced huge savings by implementing this kind of technology. Holiday Inn in Flinders, Australia, recouped its AUD $22,000 (USD $19,500) investment in low flow technology after 18 months and cut water usage by 50%.
Spotlight on Starwood and incentivisation
Starwood Hotels have committed to reduce water consumption by 20% by 2020. All hotel brands owned by Starwood in the U.S. offer a $5 voucher to spend in the shop / restaurant / bar if guests don’t have their room cleaned every day. Other hotels donate to charity when guests opt out of having rooms cleaned/ linen changed. These rewards act as an incentive but also remove any cynicism from the customer – so they understand that not changing linen is the hotel’s environmental policy, rather than simply a money saving scheme.
Spotlight on Soneva and sourcing water
Sourcing water from sustainable sources is a major priority for these luxury resorts in The Maldives and Thailand. Although water consumption in the resorts continues to rise, no water is taken from the public water supply with 60% coming from rainwater collection or wells and 40% from desalination. Since fresh water issues are a particular concern in Thailand, Soneva Kiri has built its own reservoir to collect rainwater.
Water and the stakeholder: Communicating and educating
Access to water is a human right and educating those around us about its fragility is therefore vital. Hotels have a responsibility in educating and communicating water issues to their stakeholders; employees, the local community and the customer.
As we can see from the above, a key component of a water management action plan is communication with and the education of staff. Implementing simple procedures and setting targets can play a huge role in effecting the mindset of employees when it comes to water consumption. Although this starts at the hotel, this shift in attitude is soon carried into home-life and in turn extends to others.
Where water is in short supply, being aware of competing demands for water and availability issues for a local community is vital. Hotels have to work with local communities when it comes to water use, rather than taking supplies from them.
Hotels can also play a role in educating customers about water issues, and to some extent encourage reflection on their own water use at home and when traveling. Most simply, this can be done by communicating what the hotel does to minimise water consumption and why it is committed to doing so. This can be done by:
Going one step further, hotels in particularly water-stressed areas can involve guests in their water policy. This is most successfully done in properties and places where guests are motivated to learn about the local area and community, and are environmentally aware. Initiatives include guest participation in local education or water infrastructure building and running educational tours of innovative water saving initiatives.
Spotlight on Kempinski and staff education
Kempinski’s Green Inspiration programme starts with raising awareness among guests and staff, inspiring them to adopt simple but impactful behaviours. The first of many initiatives is ‘The Oak Tree’:
“The oak tree is a symbol of strength, an ancient European tree, resistant to drought and disease. All Kempinski hotels participate in the Oak Initiative with a guest awareness programme: the small Oak Tree left on the bed by the guest invites their housekeeping attendant to make up the bed with the existing linens (reducing water used for laundry and the associated waste water), to use green cleaning products, and to turn off air-conditioning, lights and TV while the guest is not in the room. Staff contribute by purchasing goods responsibly and communicating this to suppliers - each decision to use FSC paper or buy local produce for the restaurants adds up. A hotel may also choose to support a local environmental conservation programme. Staff take part in Earth Hour each year, and a Green Day each month – where they will clean up the property and its grounds.”
Water and charity: Philanthropic approaches to water
Besides from the potential for an individual property to educate immediate stakeholders about water issues, many hotels/ hotel chains choose to interact and support broader water charity and conservation efforts. Larger hotel chains may set up their own water conservation groups, or become a primary sponsor of an existing one.
For smaller hotels, there are numerous charities and schemes that are always looking for partners. One example is Whole World Water, which encourages the tourism industry to filter, bottle and sell their own water supply and give 10% of the proceeds to the Whole World Water Fund, which seeks to provide clean and safe drinking water for everyone. Also find out about what Water Aid and Just a Drop are doing in your local area.
Spotlight on Marriott, Nobility of Nature
Marriott's "Nobility of Nature" program works with Conservation International to protect the source of fresh water in Asia for more than 2 billion people. Located in Sichuan Province, an area hard hit by the 2008 earthquake and home of the giant panda, the program will help to improve water quality in the rural communities of Pingwu County.
"Worldwide, Marriott is investing in innovative, large-scale conservation projects that help address some of the most pressing environmental problems, such as water and rainforest preservation. In China, the need for fresh water is expected to exceed its supply by 25% over the next 15 years. Helping to develop viable ways to preserve the water supply and conserve water in our hotels is one way we can help." J.W. Marriott Jr., Chairman and CEO of Marriott International.
Reporting and risk
Assessing water risk
Water security is a key issue for hotels. Water risk is not only about availability, but there are a host of other concerns such as infrastructure, governance, competing needs and water quality. A variety of tools are available online for companies and hotels that wish to take a deeper dive into assessing these risks. Most of these require water sources, annual consumption and discharge rates and the location of the property. From this they use a variety of data-sets to assess water risk. So whilst some effort would be required to gather data, the benefit is a clear picture to inform planning and investment going forward. The choice of tool will depend on the needs of the individual company so it is recommended to try these out.
