Scores of pubs have signed up to a Publican backed scheme that one licensee has described as "the best thing since running water".
With the government's mandatory code now making it obligatory for pubs to provide free tap water The Publican has teamed up with the charity WaterAid.
Through the Tap into WaterAid project we are encouraging licensees to ask for a 15p donation for every glass of water they serve. The money goes to providing safe water and sanitation in the poorest parts of the world.
So far around 200 licensees are already backing the scheme, which aims to raise £50,000 over the next 12 months.
John McCooke from The Good Ship in Kilburn, North London, has started collecting and will be encouraging others to do the same.
"It's the best idea since running water," he said "It can be quite annoying when people ask for free tap water so at least this way they will be doing some good.
"I will be urging other pubs in Kilburn to get on board too."
WaterAid's Cara Keane said: "I'm bowled over by the incredibly warm reception and commitment we've received from the pub industry regarding Tap into WaterAid.
Pubs from across the whole of the UK have been throwing their support behind the campaign by not only adopting it in their own pub, but also getting neighbouring pubs involved too."
