Fill the dishwasher and the washing machine to the optimum load. You can save up to 40 litres of water per load. Did you know that a simple dripping tap wastes more than 90 litres a week? Make sure they are properly turned off after using them. If you need to throw water away, never do it in a dry area: make use of it to water plants or gardens. Don't use the washing machine with half loads. Every time you use it, it takes an average of 95 litres - and a full load uses less than two half loads. If you are going to buy a washing machine, look for one with "GREEN PRODUCT" specifications because it will allow you to save electricity as well as water. Every time you cook hard-boiled eggs, save the water to water plants. They will benefit from the nutrients freed from the shells. Keeping a bottle of cold water in the fridge avoids having to let a bit of water run every time you want cold water from the tap. Fill a receptacle for washing fruit. If you do it with the tap running you will be using twice the water. Don't use running water to defrost food either. Take it out of the freezer the day before or use the microwave. When washing up, fill the bowl to clean the dirty dishes with soap; to rinse, set the pressure of the tap to what you really need.
