Abstract

This study introduces the design of an intelligent, fully mechanical, and cost-efficient system aimed at reducing water and energy consumption in faucets. The proposed mechanism relies on a thermostatic valve that employs temperature-sensitive components, such as bimetal strips or thermal wax, to temporarily block water flow until the desired hot or cold temperature is reached. By eliminating the need for electricity or complex electronic circuits, the device prevents significant water and energy losses typically occurring while users wait for temperature adjustment. Estimates indicate that the system can save up to 65% of wasted water and approximately 40% of the energy required for heating. The key strengths of this design lie in its structural simplicity, low production cost, and durability, which make it highly suitable for widespread use in residential buildings, hotels, public facilities, and even underserved communities. Findings confirm that this solution not only enhances resource efficiency but also offers a practical and sustainable approach for water and energy management, thereby contributing effectively to the achievement of sustainable development goals.
