33.57% Reduction in Water Consumption
A commercial property installed a 4-inch AF valve to reduce water consumption and associated water and sewer costs.
Following installation, water usage was measured against a 10-cycle pre-installation baseline and four post-installation billing cycles. The analysis measured a 33.57% reduction in water consumption, equivalent to 628,093 gallons saved during the 121-day measurement period.

Measured Results
During the 121-day post-installation measurement period, average daily water consumption decreased from approximately 15,464 gallons per day to 10,273 gallons per day.
That represents a reduction of approximately 5,190 gallons per day and 628,093 gallons over the measurement period.
Individual post-installation billing cycles showed reductions of 30.16%, 34.00%, 33.99%, and 31.31%.
Based on measured performance, the results annualize to approximately:
1.90 million gallons of water saved
$5,494 in annual operating savings
$458 in monthly savings
