Dual flush toilets. These toilets have two different settings, usually 0.8 gallons for liquid removal and 1.6 gallons for full flush solid removal. On the average they use about 2,500 gallons per year, compared to a 1.6 single flush that uses about 4,500 gallons per year. Dual flush toilets handle solid and liquid waste differently from standard American style toilets, giving the user a choice of flushes. It's an interactive toilet design that helps conserve water that has caught on quickly in countries where water is in short supply, like Australia, and in areas where water supply and treatment facilities are older or overtaxed. The Environmental Protection Agency (EPA) reports that by the year 2013, an estimated 36 states will experience water shortages as a result of increased water usage and inefficient water management from aging regional infrastructures. Using less water to flush liquid waste makes sense, but in the United States there may be cultural biases that make accepting a more hands-on approach to personal waste harder to accept [source: Safe Plumbing].
