Smartwater has been unveiled as the new Official Water Partner of the PDC ahead of the forthcoming Paddy Power World Darts Championship.
The initial 12-month agreement will see Smartwater - part of the Coca-Cola family - provide water for competing players at all PDC Premier events.
The partnership will begin in December as the biggest-ever World Darts Championship begins at Alexandra Palace in London - as 128 players compete across 20 days.
All Smartwater bottles used on stage during PDC matches are 100% recyclable, and will be sustainably disposed of as part of the agreement.
PDC Head of Commercial Adam Perfect said: "We're delighted to welcome such a high-profile brand as Smartwater as our new Official Water Partner.
"This partnership gives their unmistakeable bottles global exposure to millions across a range of PDC events, whilst providing hydration for our players during their matches on the TV stage."
Made in GB, Smartwater is made from vapour-distilled British spring water and has added electrolytes to provide its distinctive crisp, clean taste.
Smartwater designs products with reuse, recycling, and repurposing in mind, keeping materials in circulation for as long as possible, and aims to have efficient processes using energy, water, and materials to reduce environmental impact without compromising quality.
