The U.S.
Environmental Protection Agency (EPA) recently released the draft of its
WaterSense specification for showerheads
(
http://epa.gov/watersense/pp/showerheads.htm).
The WaterSense
draft specification for showerheads sets the maximum flow rate at 2.0 gallons
per minute (gpm) at a flowing pressure of 80 pounds per square inch (psi). As
with all WaterSense specifications, the draft showerhead specification includes
performance criteria to ensure that consumers will not have to sacrifice water
coverage or spray intensity in order to achieve water savings. EPA worked with
a variety of stakeholders to develop these criteria so that showerheads can be independently
tested and certified for both water efficiency and performance.
Showering
accounts for approximately 17% of residential water use in the U.S. The average
household could save more than 2,300 gallons per year by installing high-efficiency
showerheads. Once this specification is finalized, consumers will be able to
renovate their bathrooms with a full suite of WaterSense labeled products including
toilets, faucets and showerheads.
