Simple ways to save water in the home and garden

About a third of the water used in our homes is flushed away down the toilet. If you have an older toilet, each flush can use up to 14 liters of water. If a new water-saving toilet is beyond your budget, it’s very easy to reduce the amount of water that goes to flush. You can install a flush tank displacement device in your toilet, or for a faster result, fill a plastic bottle with water and place it in your flush tank. Depending on the size of the bottle, the amount of water in the rinse can be reduced by up to 3 liters. Just make sure that none of the moving parts in the cistern are blocked as this can cause problems.


We live in a notoriously rainy country, so we might as well make the best of the situation. Gardeners in particular can save a lot of water by installing a rain barrel to collect rainwater from your gutters. The liquid collected can be used to water your garden or wash your garden. In addition, many plants prefer rainwater to tap water. Chemicals, minerals and salts are added to the drinking water in our pipes, which is fine for humans but not ideal for plants. If you use rainwater from a rain barrel, it is softer and does not contain any substances that are harmful to plants.


Not only is this constant dripping annoying, it wastes water. The European Environment Agency says a dripping tap can waste up to a liter of water an hour – that wasted water would fill a bathtub within a week. To conserve extra water, don’t leave the faucet running while you’re brushing your teeth or shaving, and regularly check the floor above your pipes for signs of leaks.

car wash

Using a hose to wash your car is very simple, but have you ever wondered how much water is wasted with it? While washing with a bucket of water instead of a DIY hose would be better, you might be surprised at how water efficient your local car wash is. Many commercial car washes now use treated water to clean cars. According to Express Car Wash in Dublin: “The water is treated with detergents, used to dissolve dirt and grime to clean the car and then sucked back into a system that filters out heavy compounds and skims off light chemicals, leaving the normal behind water ready for reuse. Reverse osmosis systems add an extra cleaning to the process, distilling water until it’s even cleaner than your average tap water to give a truly spotless rinse, so your end product, a clean car, looks great.” They add that car washes come with treated water use less than two toilet flushes.
