water faucet

Lawmakers in Arizona have proposed a new bill that would require toilets, faucets and other plumbing fixtures sold in the state to work more efficiently in an effort to save water.  

“This is really kind of catching up our code with [where] technology’s at today,” said bill sponsor Rep. Kirsten Engel, D-Tucson, according to KJZZ. “And [hopefully] it’s making people think about what they’re buying.”

House Bill 2737 includes fixtures sold at retailers like the Home Depot, Lowe’s, and Ace Hardware.

The bill has bipartisan support, with Republican Reps. Noel Campbell, Kevin Payne, Republican Sen. Frank Pratt, and Democratic Sen. Lisa Otondo sponsoring the proposal.

HB 2737 would require newly-installed toilets to meet 1.28 gallons per flush (GPF). This standard matches the federal criteria managed under the Environmental Protection Agency’s WaterSense program. While the EPA does not mandate the WaterSense program, the federal government does certify fixtures that are available for purchase through most major retailers and wholesalers.

The bill would define a “plumbing fixture” as a “lavatory faucet, lavatory faucet replacement aerator, kitchen faucet, kitchen faucet replacement aerator, shower head, urinal, water closet, evaporative cooler or decorative fountain. Plumbing fixture does not include parts necessary for routine maintenance.”

If passed into law, HB 2737 would emulate rules in states like Texas, Colorado, California, Oregon, and New York state that all require WaterSense certified fixtures in all new construction. These states also require 1.28 GPF in toilet replacements in existing construction.  

Scottsdale is one of the only major metropolitan centers in Arizona that currently requires WaterSense compatible and certified fixtures in new construction within city limits, KJZZ reported. 

HB 2737 was introduced into the House on first reading on Tuesday.
