The Premier Inn at Abu Dhabi International Airport is now saving 24% of its water per month by recycling greywater.
In partnership with water management company Waterscan, the greywater recycling system works by taking water used for showering and bathing across the hotel’s 300 rooms.
Ultrafiltration (UF) membranes are used to treat the water before feeding it back into the hotel for use in flushing toilets and for irrigation.
Membranes incorporate built-in telemetry enabling remote diagnostics reporting and preventative maintenance, Waterscan said.
It is the first greywater recycling system to be approved by the Regulation and Supervision Bureau (RSB) for the Emirate of Abu Dhabi.
The initiative is reported to already be saving an average of 735,000 litres (24%) of mains water each month, around 60 litres per guest. Recycled water is now used for 100% of toilet flushing.
The hotel is the first to be built as part of the airport’s multi-billion dollar redevelopment and expansion, designed to increase its capacity to more than 40 million passengers per year.
Saving water is of primary concern in this region, which averages only 120mm rainfall each year and is one of the highest per capita water consumers in the world.
Barry Millar, operations director at Waterscan, said: “To be able to bring our latest greywater innovations to a region which suffers badly from water scarcity and to realise immediate and excellent water saving results makes us extremely proud.”
Matthew Lewis, property development director for Premier Inn Hotels in the Middle East, said: “With water scarcity a significant issue in Abu Dhabi, we wanted to take the lead and become the first ever building and the first hotelier to recycle greywater in Abu Dhabi.”
