Water efficiency refers to using water in a way that reduces waste and maximizes its benefits. This can involve practices such as fixing leaks, using water-saving fixtures, and implementing smart irrigation systems. By improving water efficiency, individuals and businesses can lower their water bills and contribute to the conservation of this vital resource. In agriculture, water efficiency is crucial for sustainable farming. Techniques like drip irrigation and rainwater harvesting help farmers use less water while maintaining crop yields. Organizations like the Environmental Protection Agency (EPA) promote water efficiency programs to encourage responsible water use across various sectors.
