The announcement, in the run up to Royal Ascot extends the successful three-year sponsorship deal signed in 2015.
Harrogate Water brand manager Nicky Cain said: “The five-year extension speaks volumes about the success of the partnership and the benefits of being associated with one of the world’s finest and most famous social and sporting venues.
“Ascot race days are internationally celebrated events, quintessentially British and synonymous with elegance and style; the sponsorship is a perfect fit for both brands.
Harrogate Water and Ascot are also working together on a sustainability project to improve recycling across the site. The project builds on the Incredible Shrinking Bottle ‘Twist it. Cap it. Recycle it.’ campaign launched by Harrogate Water and Keep Britain Tidy. It will include greater staff awareness and improved recycling systems to be rolled out across the estate. All Harrogate Water packaging is 100 per cent recyclable and its PET plastic bottles contain 51 per cent UK post-consumer recycled plastic (rPET).
