The average cost of a litre of bottled water is £1. It doesn’t sound like a lot, but £1 will buy you 10,000 litres of tap water.

The tap water in the UK is among the safest and purest in the world and yet we waste over £2bn every year on buying, mostly imported, bottled water.

It is much cheaper and much more environmentally friendly to drink water from the tap.

Just the packaging for bottled water causes a huge amount of waste and that doesn’t even consider the carbon footprint it takes to get it from the source onto the shelves in the supermarket.

Restaurants make huge profits on bottled water because so many of us are too embarrassed to ask for tap water.

Don’t pay for something that is free.

Ask for tap water and drink it proudly.
