Earlier this year the Government announced that bottled water would no longer be served in Cabinet sessions. In addition to saving a fair chunk of taxpayers pounds (an estimated quarter of a million bottles are purchased by government departments each year) there are significant savings to the environment by choosing the tap option.

Every year 1.5 million tons of plastic is used to package water. That's an awful lot of years to breakdown in landfill or if the plastic makes it to a recycling plant the amount of energy used to convert it into a reuseable product adds far more CO2 to our atmosphere that if we'd chosen to hydrate via the tap.

Bottled water is ├╝ber expensive. In fact it's twice as much as petrol and 10,000 times the cost of tap water. Most companies pay absolutely nothing for the water they extract from the earth - packaging, machinery to extract it with and transportation are where their expenses lie.

Some argue bottled water tastes better but this doesn't mean it's healthier or safer as many believe. Studies have found the same minerals in tap water, and the big water brands use 'the health benefit' as a major selling point. But a Natural Resources Defence Council (NRDC) report found that 40% of bottled water was in fact tap water.

For those who aren't so keen on the tap water in their local area, reverse osmosis water filtering systems may be a worthwhile investment.
