Clean Water

Challenges, Risks & Mitigation

Shangri-La Hotel & Resorts

Global Challenges – a perspective

Source: Internet - Global Future Studies & Research - The Millennium Project

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

Shangri-La Hotels & Resorts

Reduction in Average Annual Water Use Per Hotel, Cu Mt

Main Areas of Water Use in Hotels & Resorts

Potable Water

•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

Main Areas of Water Use in Hotels & Resorts

Irrigation

• Garden and landscape

• External area washing

Quality

• preferred treated recycled STP water

• Potable water if STP not available

Standards

• Preferred auo-controlled irrigation

system

• Fittings and hoses to be water tight

• Taps flow rate <12 liter/min

Cooling Tower

• Make-Up

• blowdown

Quality

• preferred treated recycled STP water

• Potable water if STP not available

Standards

• Metered to monitor make-up rate for

evaporation and blow down loss

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
