Depending on how fast it's dripping, a defective faucet can waste up to 45 liters of water a day. On top of that, stopping that drip is good for your nerves.

Turning off the tap when brushing your teeth or shaving can save a lot of water in your hygiene routine.

This is an easy one – you'll use 50 liters instead of a whole 150 liters of domestic hot water, saving water and the energy that would have been needed to heat it.

There's another simple trick for saving a lot of water – simply spend less time in the shower. You can daydream later on the couch.

Just like when shaving and brushing your teeth: only let the water run when you actually need it.

Dual-flush toilets with a smaller button for liquid waste are already common. So choose that button whenever you can.

Prewashing is simply no longer necessary with today's textiles and the mostly low level of soiling. So skip this step and save water and energy.

It's better and more economical to put some water in the sink and clean the dirty dishes there.

A splotch of salad dressing or a few crumbs? Don't worry, your dishwasher is up to the job.

Obviously, the smart approach with washing machines applies here too: a full dishwasher is more efficient in terms of water and energy.

Water your plants where they need it, at the roots. There's simply no point in wetting their leaves.

Water saving: this way, less water evaporates in the sunlight and so the garden needs less watering.
