Our Hotels & Resorts – Water Supply Sources
• 100% Municipal/city supplied – the majority of hotels
• 100% In-house produced – Desalination plant – remote resorts
• Combination of water supply: City + Desalination Plant + Other
Sources
Other Sources
• In-house Sewage Treatment Plant
• Rainwater Harvesting Plant
• Truck-in water

Major Water Challenges & Risks for the Hotels
External Factors
• Diminishing Sources – drying up of natural
sources – rivers, lakes, wells
• Availability – consistency from Municipal supply?,
• Reliability – at contracted volume, pressure,
seasonal variations
• Quality – to WHO standards? need further in
house treatment ?quality of untreated trucked-in
supply? Etc

Major Water Challenges & Risks for the Hotels
Internal Challenges
• External factors – as above driving availability, reliability, quality
• Unaccounted Use – lack of metering, tracking/trending,
benchmarking
• Underground Leaks – timely tracing and repairs
• Operational Wastage – attitudes, training, discipline
• Water Unit Rates – varied: subsidies – too low rates, high rates
• Poor Hydraulic Systems Design – oversized pumps, pressures

•Guestrooms basins, showers, bathtubs
kitchens, swimming pool, water features
etc
Quality
•to WHO standards with UV treatment at
outgoing after storage tanks
Standards
•Water basins - < 6 liters/minute
•Showers – < 12 liters/minute
•Kitchen Sinks – <12 liters/minute
Flushing Water
•Water closets – cistern and flush valves
•Urinals – auto sensors and self closing
taps
Quality
•preferred treated recycled STP water
•Potable water if STP not available
Standards
•WCs - 4.5 to 6 liters/minute
•Urinals – 1.5 liters/minute
![Page 8: Clean Water - ESCAP · • Diminishing Sources – drying up of natural sources – rivers, lakes, wells ... WCs - 4.5 to 6 liters/minute Urinals –1.5 liters/minute. Main Areas](https://reader033.vdocuments.site/reader033/viewer/2022052015/602d09e803a35a0af93b7b0f/html5/thumbnails/8.jpg)

Group’s Mitigation Measures
• Constant Standards Review – adopt more stringent and mandatory
National codes ?
• Kitchen taps – 6 liters/min instead of 12 liters/min
• Basins – 4 liters/mon instead of 6 liters/min
• Showers – 9 liters/min instead of 12 liters/min
• Benchmarking and Aggressive Reduction Targets
• 1st 5 years 2011-2015 Group Water Reduction Target (next slides)
• 2nd 5-years 2016-2020 Group Water Reduction Target
• Monitoring and Analytic Tools
• sub-metering, trending and analysis
• Management Drive
• Management involvement
• Best Practices
• New Technologies – research, adopt and implement
