Harrogate Spring Water has secured a deal with Purple Foodservice Solutions, the food contractor which supplies the Ministry of Defence (MoD) with bottled water.
The announcement of the contract marks the anniversary of The Great War, as well as Harrogate Water's centennial year of working with the MoD, after the company was supplied to British Forces in Bombay in 1914.
Almost two million bottles of Harrogate spring water will be supplied to the Royal Navy, Royal Air Force, the Army and HM ships and submarines, across MoD bases across the UK and around the world.
James Cain, managing director of Harrogate Water Brands said: "We're absolutely thrilled to be supplying British sailors, soldiers, airmen and airwomen with our spring water. It is incredible to think that Harrogate water has been playing its part in hydrating the troops since the First World War.
The deal, which follows the water company's recent rebrand including the introduction of a new bottle design, will dramatically increase sales for Harrogate Spring Water, an independent, family owned company.
Cain added: "The armed forces do such an incredible job; I don't think we can ever begin to understand the pressures they go through on our behalf. To commence this special relationship on such a historic and unforgettable anniversary 100 years on makes us very proud indeed."
