Water

Water consumption alone accounts for 3% of all electricity generated in the UK and a significant proportion of the total energy requirement is used to heat water. It has been calculated that the energy required to provide 1000 m³ of non heated water generates 300 kg of CO₂ and 350 kg of CO₂ to remove and treat the waste water. This equates the generation of 650 kg of CO₂ per 1000 m³ of water supplied and delivered.

The UK has less water reserves than some parts of Southern Europe; making it prone to droughts. The average person in the UK uses 150 litres per day, equivalent to 264 pints, which is simply not sustainable. The national target is to reduce this to a maximum of 130 litres per day. Water consumption has continued to increase since the 1960's and we now use about 50% more water than we did 25 years ago.

Water Saving

Thames Water are keen to work with schools to help reduce their water consumption, by mending leaks and using water more efficiently. As well as providing educational resources on the importance of water efficiency, Thames Water also provide audits for schools who are interested in using less water and reducing their bills.

• Free water saving devices (Hippos and Save-a-flushes) for older toilet cisterns (handle rather than dual flush) can be ordered through the sustainability unit.
• Waterwise were set up to help the UK reduce its water consumption. They have some more resources for schools to help save water.

Water Makeover

Between September 2008 and July 2009, 20 schools in the borough took part in the 'Water Makeover: what not to waste' project. Funded by Thames Water, this special project was set up to reduce water consumption in schools whilst actively engaging pupils to provide a deeper understanding about the need to save water.

Water use in participating schools was monitored over a period of months and professional water audits were carried out to identify where savings can be made. Water saving devices such as urinal controls and regulators for taps have been installed, aiming to save both water and money. Over 4000 pupils took part in assemblies and workshops on water saving including home water surveys and finding out 'How much does it cost to flush your toilet?'.

Between them, the 20 schools will save more than 36,777 cubic metres of water and 27.9 tonnes of carbon dioxide every year, which equates to a staggering £58,475 per year.
