Greywater usage in hotels can greatly assist in cutting down water costs but it can also improve a hotel's reputation by proactively protecting the environment.

Water is used in many areas of hotels, motels, serviced apartments etc. The majority of water is used by hotel guests in their room. They can actually consume between 40 to 56 per cent of the total water consumption of a hotel. Most hotels address the issue of water usage per occupied guestroom per day . The average hotel uses 1500 liters per occupied guestroom, per day which is approximately 50% of the total water usage, resulting in approximately 500 net liters of grey water.

Hotels use a lot of water in the kitchens for cooking and cleaning and in hotel laundries to operate washing machines, steam boilers and steam irons. Hotel pools, spas and fountains lose water through evaporation, splashing, backwash operations and leaks and poolside showers and all hotel garden areas and indoor plants require the necessary irrigation. The above activities comprise of 50%-80% of a standard hotels wastewater. Similar water usage can be associated with country clubs, spas and water parks etc.
Wastewater can also be extracted and gathered from additional sources including cooling towers, air conditioning units, and rainwater harvesting and green roofs.

If this wastewater can be effectively collected and recycled, it could meet the growing demands of the hotel industry while dramatically reducing costs.

Background information on Hotels:

Hotel water consumption is an environmental issue addressed by eco-tourism, a market segment that creates public global warming awareness and sustainable development. However, water consumption is also an important economical issue for hotel management. Although hotels typically represent less than 5% of a nation's building stock, the global hotel industry comprises of over 300,000 facilities. Due to the high level of resource utilization (energy, water, consumables) in hotel facilities, the environmental footprint of hotels is typically larger than those of other types of buildings of a similar size.

Hotel water consumption can vary between 350 and 900 liters per occupied guestroom per day. An average of 200 cubic meters of fresh water is consumed per room, per year, and a 500 rooms hotel water charge can be anywhere between 100,000 - 200,000 US Dollars a year, according to a tariff of 1-2 $/cubic meter. Saving around 30% of water expenses can be achieved by several cost effective methods to reduce OPEX, enhance hotel profitability, elevate the public perspective possibly support government incentives.

Water saving and recycling are aligned with The International Ecotourism Society (TIES) benchmark, LEED regulations and other sustainability guidelines.

The median water consumption per occupied room was reported to be - 545 liter per day (l/d/r) according to a survey of 408 American hotels ("Water Consumption in the Lodging Industry", Stipanuk & Robson, 1990).

Water consumption data is displayed in the following tables:

Hotel size Water consumption (median)(Liter per day per room)
All 408 hotel surveys 545
Less than 75 rooms 380
More than 500 rooms 785
Resort/Casino/Conference Centers 960


Water Usage Range Median
On-Site Laundries 5% and 30% 14%. About 20 liters per kg of laundry or 100 liters per room per day.
Kitchens 0.05% to 25% 6%. 45 liters per room per day
Irrigation 1% and 44% 14%.
Cooling Towers 1% and 21% 9%.
