The document discusses using recycled water at a school to save fresh water from being wasted in toilets and gardens. It notes that students may not know the difference between a full flush and a half flush in toilets, which can waste water. It also provides information on the school's water bills from November 2010 to March 2011, with one bill totaling $1,196.10 and another lower bill of $197.10 likely due to reduced water usage during summer holidays.
