  11. 12. Tips for Saving a Water <ul><li>Just taking a five minute shower very day, instead of a bath, will use a third of the water, saving up to 400 litres a week. </li></ul><ul><li>Replacing a toilet cistern can save water. Toilets manufactured after 1993 use less water per flush. </li></ul><ul><li>Brushing your teeth with the tap running wastes almost 9 litres a minute. Rinse out from a tumbler instead. </li></ul>

Tips for Saving a Water <ul><li>A d ripping tap could waste as much as 90 litres a week. </li></ul><ul><li>Lag your pipes to avoid bursts and leave your heating on a low setting while you are out in cold weather to prevent pipes freezing. </li></ul><ul><li>Trigger nozzles can save water by using it only when needed. This can save up to 225 litres a week. </li></ul>
  13. 14. Tips for Saving a Water <ul><li>Very 'water efficient' washing machines and dishwashers are now manufactured. Machines with 'A' ratings are the most economical. </li></ul><ul><li>Don't use your washing machine until you've got a full load. The average wash needs about 95 litres. A full load uses less water than 2 half loads. </li></ul><ul><li>Installing a water meter can save you water and money by monitoring how much you use. Or even newspaper keeps the sun off the soil and retains precious moisture </li></ul>
  14. 15. Water saving advance for gardeners <ul><li>Purchasing a water butt will help you to collect rain water for use on the garden. </li></ul><ul><li>Question your local garden centre about the water requirements of different plants. Some thrive in drier conditions. </li></ul><ul><li>Mulch for moisture in the garden. Adding a layer of tree bark, compost, coconut husks as much water in an hour as a family of four will use in a day! </li></ul>
  15. 16. Water saving advance for gardeners <ul><li>Use the dirty water when cleaning a fish tank on your houseplants. It's rich in nitrogen and phosphorus, which provides an excellent fertiliser. </li></ul><ul><li>Every time you boil an egg save the cooled water for your houseplants. They'll benefit from the nutrients released from the shell. </li></ul><ul><li>Grow your grass a little longer. It will stay greener than a close mown lawn and need less watering. </li></ul>
  16. 17. Water saving advance for gardeners <ul><li>Hoeing stimulates the growth of plants, reduces water loss from the soil surface and removes weeds that take up valuable water and nutrients. </li></ul><ul><li>No further watering is usually required for established trees and shrubs. </li></ul><ul><li>Sprinklers can be wasteful. It doesn't take long for a sprinkler to soak your lawn thoroughly. </li></ul>
