Water
Saving water is probably an area that most people are aware of and have already taken steps towards. I know when water meters first started to be installed people took a lot more interest in their water use.
Take the Mains to Rains pledge - Water the way nature intended Go to Mains to Rains adopt a few simple pledges to make a difference to your garden and the environment.
Turn the tap off while cleaning your teeth. It could save you up to £36 * on your water bill too!
Fix dripping taps a tap can waste more than 60 litres of water per week.
Shower rather than take a bath. It will save 50 litres of water. When we had the children living at home I think a bath might have been cheaper and better on the knuckles from trying to get their attention 30 mins after they entered the bathroom for a shower.
Change over to smaller toilet cisterns. Or use a cistern bag, our water company will send you one for free, check with your water provider.
Use a dual flush cistern.
Check your toilet isn't leaking down the back of the bowl between flushes. Dual flushes can have sticky buttons
Use aerator taps and an aerator shower head. I think most new taps are fitted with aerators. Our water company gives away swivel tap aerators.
Fit a regulated shower head or tap insert. Again these are freebies that you can get from some water companies.
Collect rainwater in a water butt. Our water company has special offers on water butts.
Use water from hand washing up to water the garden (something we don't do because I hate washing up bowls!)
Use water from cooking. Nutrients leach in to the cooking water from your food. Calcium rich water from boiled eggs can be given to tomatoes and peppers. Iron rich water from greens. Potato and pasta water is also good for the garden if you don't put salt in.
Only run the dishwasher and washing machine with a full load.
Think carefully before using a hosepipe can you do the job with a bucket and sponge? A hosepipe can use up to 1,000 of water an hour.
