Waterscan is delighted to announce the successful implementation of a ground-breaking approach to water sustainability in the Middle East, working in partnership with long-term client Premier Inn Hotels. The initiative is destined to help relieve water scarcity and provide a blueprint for the future of the hospitality sector.

Waterscan devised an innovative greywater recycling system for one of Premier Inn’s newest hotels, the Premier Inn at Abu Dhabi International Airport. It is the first major hotel 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.

The Waterscan greywater recycling system works by taking water used for showering and bathing across the hotel’s 300 rooms and treats it through an ultra-filtration membrane before feeding it back into the hotel for use in flushing toilets and for irrigation. The initiative is vastly reducing mains water consumption, already saving an average of 735,000 litres (24%) of mains water each month – that’s 60 litres per guest. Over the course of a year, this is the equivalent of 110,000 baths. 100% of toilet flushing at the hotel now uses recycled water.

Barry Millar, Operations Director at Waterscan, said: “We were delighted to be involved in such a prestigious project. 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.”

Waterscan’s greywater recycling system is designed with innovative, low energy components to deliver higher energy efficiency and lower running costs. The system’s membrane provides a fixed barrier to waterborne viruses and pathogens and, for added peace of mind, it incorporates built-in telemetry enabling remote diagnostics reporting and preventative maintenance. It is the first greywater recycling system to be approved by the Regulation and Supervision Bureau for the Emirate of Abu Dhabi.

Matthew Lewis, Property Development Director for Premier Inn Hotels in the Middle East, said: “Reducing our impact on local water supplies and acting sustainably in the areas we operate is a key driver for Premier Inn Hotels and the Whitbread Group. We have worked with Waterscan for a number of years, setting them ambitious targets to achieve our water sustainability goals, which they always find a way of achieving.”

He continued: “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. Our new bespoke greywater recycling system incorporates innovative features to ensure system reliability and guarantees that the customer experience will not be affected. The system is producing great results, and we are now rolling it out across the Middle East, designing all our own new hotels in the region with this technology.”

The award-winning Premier Inn is able to operate sustainably and provides great value for money and uniquely offers customers a ‘great night guarantee’. All bedrooms feature en-suite bathrooms and complimentary Wi-Fi, while all hotels offer a gymnasium, swimming pool, Costa Coffee store and an all-day dining restaurant. Each Premier Inn room can comfortably sleep up to two adults and two children at no additional cost. For more details visit
