Car Washes Pay More for Water Per Square Foot Than Almost Any Business — AWS Reports Average Savings Just Above 22% Across North American Projects
The Caliber review covers five Georgia and Florida installations. It reports a 20% average overall daily-water-use reduction and 23% weighted matched-calendar-month savings, with site-specific variation and exceptions.

Why Are Car Washes the Best Candidate for Water Bill Savings?
Car washes run water continuously — no slow periods, no off-hours. Smart Valve™ works 24/7/365. The more you wash, the more you save.
Continuous High-Volume Water Use
Car washes are among the highest water-intensity commercial operations in existence. A tunnel wash uses 50–120 gallons per car. At 1,000 cars/day, that's 50,000–120,000 gallons per day — every gallon subject to air entrapment billing inflation.
Two Distinct Caliber Measures
Across five Georgia and Florida installations, the review found a 20% average overall daily-water-use reduction and 23% weighted matched-calendar-month savings. The figures use different calculation views and should not be collapsed into one average.
Compound Savings as Rates Rise
Car wash water bills grow with rate increases. A 23% reduction on a $20,000/month bill delivers $4,600/month in savings. As rates rise 6–8% annually, the same percentage cut delivers more dollars every year.
Bill-Level Evidence
The Caliber analysis used bill-level utility data, prior-year baselines, and varying comparable periods. Variable water and sewer charges were included while fixed charges were excluded.
Site-Specific Results
Results varied by site. Benbrooke's missing branch was excluded, and Flagler Beach was normalized per wash because wash volume increased.
NSF 61 & 372 Safe for Car Wash Use
The Smart Valve™ is NSF 61 and NSF 372 certified. It is completely safe for installation in commercial car wash supply systems.
Why do car washes have some of the highest water pressure problems of any commercial facility?
Car washes operate at extremely high flow rates for short, intense bursts — exactly the conditions that cause the most significant meter over-reading. Each wash cycle switches the system from static to dynamic flow, creating a pressure surge that pushes the meter outside its accurate measurement range. High-volume tunnel car washes processing 200+ vehicles per day can see annual water bills in the six figures, with a meaningful portion attributable to air measurement and meter over-recording from pressure surges rather than actual water consumed.
