Changes

Water consumption can be reduced using (descending order) water-efficient shower heads, toilets, dishwashers, clothes washers, and automatically closing taps. Low-flow shower heads alone can reduce water usage by 30%. Older shower heads deliver 4 to 5 gallons (15.1 to 18.9 litres) of water per minute. The [http://www3.epa.gov/ USA Environmental Protetion] Agency ,<i>WaterSense</i> lavatory faucet specification sets the maximum flow rate of lavatory faucets and faucet accessories at 1.5 gallons per minute (gpm) tested at a flowing pressure of 60 pounds per square inch (psi) (common water pressure in most households).<ref>http://www3.epa.gov/watersense/pubs/faq_bs.html</ref>
