Shine will handle the PR element of Volvic's annual integrated marketing campaign, which began at the end of March and aims to show people the positive benefits of drinking 1.5 litres of water a day.
Shine will attempt to target the brand's core target market of 18- to 34-year-olds, both male and female. It will emphasise how water can make you feel physically and mentally alert and active.
The agency is understood to have won the business, worth more than £100,000, following a three-way pitch. The contract is initially for six months.
Shine has not worked on the Volvic brand before, but it is retained on Danone's Evian brief. It has worked on Evian for the past three years.
Danone Waters brand manager Nicholas Britton said: ‘Shine is currently working with us on a project basis, rather than an account retainer. In terms of the other details, it is company policy not to comment on the details of agency relationships.'
