Water efficiency

What is water efficiency?

Water efficiency means promoting the sustainable use of water, while using solutions that enable comprehensive reductions in the waste of domestic water. Implementing water-efficient measures makes it possible to substantially save on water, energy, and costs.

While water efficiency and water conservation both promote the responsible use of water, they are two different things.

Water conservation is the effort to reduce the direct consumption of water. Everyday examples of water-saving measures in households include turning the tap off while soaping up your hands, showering only briefly, using dishwashers and washing machines only when full, and fixing leaks quickly.

Water efficiency, on the other hand, aims to make the use of water sustainable to a broader extent. The idea is to both reduce unnecessary water consumption and make water consumption more sustainable by focusing on responsible solutions for the use and supply of water.

In other words, water efficiency means reducing the water used by water functions without compromising the comfort and convenience of your water supply. Examples of solutions promoting long-term water efficiency are technology that measures water consumption, water-saving fittings and environmental certifications for properties.

Which measures enhance water efficiency?

Environmental certifications for properties. Numerous green construction certificates take water efficiency goals into account as part of sustainable construction. Ecofriendly construction is a sustainable trend, the focus on which will only increase in the coming years.

Correct water pressure levels. It's a significant and unnecessary waste of water when the water supply is set at an excessive pressure level, which often happens in apartment buildings around the world. Flow rates should be set at a level where water can flow smoothly to the highest floors and is still sustainable.

Technology to measure water consumption. Once real-time data on water consumption is available, it can be used to implement water-saving measures that will have a permanent, positive impact on reducing water waste. A small water leak that's not noticed in time, for example, can lead to thousands of euros in waste and damage.

Water-saving water fittings and appliances. Measures like water-saving shower heads and dual-flush toilets can save up to dozens of liters of water every day per end user.

Energy-efficient household appliances. An everyday example of water efficiency is to invest in technology that avoids wasting water, like low-water-use washing machines.
