The Water Conservation Project (WCP) is a design concept to reduce the water consumption on startup of a shower. Every time a shower is started with a conventional tank water heater, approximately 7.5 liters of cold water is flushed down the drain without being used before the hot water reaches the faucet. For a city the size of San Luis Obispo, this amounts to approximately 121 million liter of water per year. The main goal of this project was to devise a way to conserve the cold water that is contained in the hot water pipes before every shower. Ultimately, we searched to create a system that minimizes the amount of work required by the consumer, yet still allowed them the ability to shower conveniently. Wolfgang Kaml is the sponsor of WCP and the project was carried out by two collaborating teams at California Polytechnic State University San Luis Obispo and Munich University of Applied Sciences.
