Over two and a half billion people in the world do not have access to a toilet and nearly a billion people lack safe drinking water. Meanwhile, most Americans toilets filled with drinking-quality water before flushing it away to the sewers.
Flushing toilets use about 30% of the water in an average residence. If your home has a toilet made before 1992, there is a very good change that it uses about 3.5 gallons of water per flush. Newer models of toilets can do the same job with much less water. In fact, new high-efficiency toilets use only about 1.3 gallons per flush.
All of this adds up to a lot of wastewater that needs to be treated. Each day, 45 billion gallons of wastewater go down the drain that must be treated at one of the 16,000 water treatment plants in the U.S., according to EPA statistics. Do your part to reduce the load on our receiving lakes, rivers, and streams by installed a high efficiency toilet.
