The document describes an experiment to track toilet flushing habits over one week in a house with three residents. A scorecard was used to track "saved" flushes for urination versus full flushes. Over the week, there were 79 saved flushes and 30 full flushes, saving 112 gallons of water. If adopted annually, the technique could save over 5,800 gallons of water per household, demonstrating that selective flushing can significantly reduce toilet water usage.
