Water efficiency and quality

Our water focus

To reduce water use we focus on preventing and fixing water network leaks. We also include water saving technology in building refurbishments and capital projects.

We collect surface water from the airfield and car parks to treat it. Our long term river biological sampling programme shows that the airport does not have a negative effect on local rivers.

Water is a focus of our sustainability policyWater forms part of our sustainability policy - our Decade of Change.

Onsite surface water processing

We have over 50 interceptors tanks in our surface water drainage system. These collect grit, sediment and oil, to prevent them from reaching our local rivers.
Our partner Sweeptech uses a tanker to process the contaminated water on board. It returns only the clean water to the drain. This new process saves in the region of 5 tonnes CO2 per annum.
