Georgia Joins California and Texas 1.6 Gallon Flush Toilets Illegal

1.6 Gallon Toilet Tanks to become a thing of the past.

In the 1980s and early 90s, multiple states adopted standards setting maximum water use levels for showerheads, faucets, toilets, and urinals. Based on these standards, Congress adopted national standards on these products in the Energy Policy Act of 1992. The standard for toilets which took effect in 1994 is 1.6 gpf (gallons per flush).

Under the law, if the American Society of Mechanical Engineers (ASME) revises these standards, DOE is obligated to review ASME's action and consider revising the federal standards. If ASME does not revise the standards within five years, states are free to set more stringent standards themselves. To date, ASME has not revised any of these standards. On December 22, 2010, DOE officially waived preemption for plumbing products, allowing states to set standards provided that they are more stringent than the 1994 federal standards.

California, Georgia and Texas have adopted toilet efficiency standards that require products to use no more than 1.28 gpf. The 2012 ASAP/ACEEE report, The Efficiency Boom, analyzed potential toilet standards based on this 1.28 gpf level, estimating savings of 92 billion gallons of water and $4.3 billion dollars in net present value through 2035. Products meeting the 1.28 gpf level currently meet the qualifications for the EPA WaterSense program (similar to ENERGY STAR but focused on helping consumers identify water-efficient products). More efficient toilets are not expected to cost any more than toilets meeting the current standard.
Toilets are included on the California Energy Commission Phase 1 rulemaking docket with a final rule expected in 2014.
