Looser standards for showerheads could drain water, cost more money
For more than 25 years, Congress has directed U.S. government agencies to set energy and water efficiency standards for many new products. These measures conserve resources and save consumers a lot of money. Until recently, they had bipartisan support.
But President Trump has turned efficiency standards into symbols of intrusive government. His administration has opposed many of these rules, including standards for light bulbs, commercial boilers, portable air conditioners and low-flow toilets. His latest target: showerheads.
The Energy Policy Act of 1992, passed by a Democratic Congress and signed by Republican President George H.W. Bush, set the maximum flow rate for showers at 2.5 gallons per minute. President Trump is proposing to increase the rate, which he calls inadequate to wash his “beautiful hair.”
It may sound funny, but it's not. As someone who writes and teaches about water law and policy, I know that the U.S. water supply is finite and exhaustible. Most Americans take water for granted, but as population growth and climate change exacerbate water shortages, experts increasingly argue that water policy should promote conservation
On Aug. 13, the Department of Energy's Office of Energy Efficiency and Renewable Energy issued a Notice of Proposed Rule making to amend the existing standard for showerheads. The documentation prints out at 25 pages of mind- numbing rationalization. Its definition of showerheads exemplifies the byzantine logic behind this policy shift.
For example, the proposed rule provides three images of fixtures with between three and eight heads attached to a single pipe coming out of the wall. So long as none of the individual heads has a flow greater than 2.5 gallons per minute, the measure asserts that each fixture satisfies Congress's quest for water and energy conservation.
How can the Energy Department allow shower fixtures with as many as eight heads, each emitting 2.5 gallons per minute? For context, Webster's dictionary defines a showerhead as a “fixture for directing the spray of water in a bathroom shower.”
But the proposed rule interprets “showerhead” to mean “an accessory to a supply fitting for spraying water onto a bather.” With this sleight of hand, a congressional rule limiting showerhead flows can be deftly avoided by installing a hydra-headed fixture with multiple“shower heads ,” each flowing at 2.5 gallons per minute.
The agency also released a fourth image of a wall fixture with seven nozzles, which the rule would not subject to the 2.5 gallons per minute maximum. The Energy Department deems these fixtures a “body spray” rather than a showerhead because they are “usually located” below the bather's head. (Of course, the person showering may be short, or the plumber may install the fixture high on the shower wall.) Body sprays may have six or eight nozzles with no flow limits.
The sad part of this foolishness is that the Environmental Protection Agency' s WaterSense program, which identifies water-efficient projects and promotes water conservation, has been spectacularly successful, at virtually no cost to consumers or the regulated community.
