Hippo the Water Saver is the simple, proven and low cost water saving device to help conserve water in toilet cisterns. The typical family uses 70% of their water in the bathroom, with toilet flushing accounting for 30% of the household water use. Every time a toilet is flushed the Hippo not only saves up to 3 litres of water, but it will also reduce your carbon footprint and save you money.

The carbon footprint of unheated water is relatively small, around 0.003 kg per litre. However over time and multiplied by millions of households, the savings can be quite significant. There are estimated to be in excess of 45 million toilets in the UK, using 2 billion litres of water every day and only around a tenth of these are water-efficient models using 6 litres of water or less. The average toilet uses around 9 litres of water per flush and 1.64 kg CO2 would be saved per year by fitting a Hippo the Water Saver. Collectively in the UK this could save around 600 million litres if water a day and over 65 million kg (or 65,000 tonnes) of CO2 each year (source - green thing wiki).

We probably all use water without considering the carbon emmissions associated with its supply, disposal and heating. Staggering as it may seem, this accounts for five percent of the UK’s carbon emissions and equals that of all UK aviation traffic.

Waterwise's research showed that the energy used to pump, treat and heat the water in the average family home in one year produces the carbon equivalent of a return flight from London to New York.

Many toilets will flush just as effectively with less water. By putting Hippos into your cisterns you can reduce the amount flushed away and for those on a metered supply this means a significant and sustained saving on water and your water bills.
