vandeffektivitet
Vandeffektivitet, or water efficiency, is the practice of meeting water needs with minimal waste and environmental impact. It combines technological, infrastructural, and behavioral measures to reduce the amount of water required for a given purpose and to minimize losses in the supply system.
Key metrics include water use efficiency (WUE), water use intensity (WUI), and non-revenue water (NRW). In households,
Approaches include low-flow fixtures, efficient irrigation, cooling-water recirculation, and water recycling and reuse. Strengthened metering, leak
Policy tools such as building codes, appliance standards, water pricing, retrofit incentives, and labeling schemes help
Benefits include lower operating costs, greater drought resilience, and energy savings; challenges include upfront capital costs,
