UK luxury automaker Bentley has reduced its water usage by 35.7 per cent over the previous year at its headquarters in Crewe, to 109,284 m³ in 2012.
As a result, the company has become the first automotive manufacturer in the world to achieve the Carbon Trust Water Standard.
The Carbon Trust Water Standard is the world's first water use reduction certificate, measuring and managing water use of organisations.
As part of the reduction, Bentley's Paint Shop and water treatment facilities were renovated, and a dedicated water recycling facility was built. This facility enables Bentley to re-use water efficiently, with little wastage, preparing cars as they enter the paint spraying process.
Bentley also invested heavily in the replacement and modernisation of major sections of both the water main and fire hydrant systems across the site, eliminating many underground leaks that occurred because of the more traditional mains supply pipes.
The domestic services throughout the Bentley factory were also analysed by the Environmental Team, choosing to install automatic taps and low-flush toilets in washrooms, saving over 1,500m³ of water every year.
However as Autobloggreen points out, Bentley is not universally lauded as an environmentally progressive organisation.
Earlier this year, the Bentley Muslane was named the ninth "meanest" US production vehicle to the environment by the American Council for an Energy-Efficient Economy (ACEEE).
This ranking was earned because of the fuel efficiency of the vehicle. It has a 6.8-litre V8 engines with a 11/18 city/highway fuel-efficiency split.
