The present invention is a passive water-cooling system designed to reduce the temperature of water supplied to a home. The system comprises a plurality of interconnected cooling devices, each featuring a hollow, elongated “S”-shaped pipe made of thermally conductive materials, such as stainless steel. The devices are installed underground (i.e., below ground surface level) and connected to the main water supply, forming a sealed, leak-proof reservoir system. As water flows through the system, it is cooled by transferring heat to the surrounding ground. The system may include detachable connections to prevent overcooling in winter and can be integrated with rainwater harvesting systems for enhanced sustainability.
