Qualifying old and new replacement fixtures include toilets, showerheads, and clothes washers that meet the flow rate requirements specified in the verification form. New fixtures must result in water savings. Effective March 10th, 2014, toilet and showerhead retrofit credits can no longer come from the Prohibition Zone. Water savings will be calculated as average gallons saved per day based on the existing and retrofitted fixtures. See the form on file with the department for the water savings calculation methodology.
