Bentley Motors has always been forward-thinking when it comes to water saving. Bentley’s focus on water usage has spanned 20 years, in that time reducing the amount of water per car by 89%. The amount of water Bentley used in vehicle production has fallen by 55.9% over a 10-year period from 2010-2020, from 21.1 cubic meters to 9.31 cubic meters per vehicle. This saving of almost 12 m3 per vehicle equates to around 150 bathtubs full of water.

In 2019 Stormsaver commissioned Bentley’s first rainwater harvesting system with a 20,000L tank capacity. This was instrumental in achieving the successful reductions in water consumption. But Bentley wanted to go further and harvest even more rainwater, so in 2019 we worked closely with its engineering team to retrofit our flagship product, The StormStation. This, all in one, plug and play unit combines a 15,000L storage tank, two integrated filters and pumps, supplying a pressurised supply of water to toilets and urinals. With a combined capacity of 35,000L, the new system is estimated to save more than 1,800L of water every day.

Quick Quote

“Stormsaver has helped us to upgrade the existing rainwater harvesting system. We desperately needed support and within one month they had attended site, carried out a survey, manufactured the new control panel, and installed and commissioned the system. Together the team at Stormsaver responded quickly, understood our requirements, and worked to ensure that we had the best solution. Their knowledge and expertise have resulted in us now having a fully functional, efficient rainwater harvesting system and we would highly recommend that other clients who need their existing rainwater system upgrading, contact Stormsaver for support.”
