Frequently Asked Questions
What RO system capacity do I need to operate a profitable water vending business?
A single water vending machine selling 100-300 gallons per day needs an RO system producing at least 500-1,000 GPD to maintain adequate storage buffer and recover from demand spikes. Our water store packages pair correctly sized RO systems with pressurized storage tanks so the vending machine always has product available even during the morning rush. Undersizing the RO relative to storage is the most common mistake in water store startups.
What fill station configurations do you supply for water stores?
We build countertop fill stations for 1-5 gallon container filling, wall-mount stations for high-volume walk-in stores, and drive-through outdoor vending kiosks that accept coin, bill, credit card, or contactless payment. All configurations include carbon post-filtration to remove any taste carry-over from storage and to present the freshest possible product at the point of fill. Custom configurations for water store build-outs are available.
How does UV disinfection in water store equipment protect customers?
Our systems include a final-stage UV lamp rated at 254 nm and a minimum dose of 30,000 microwatt-seconds per square centimeter, which inactivates bacteria and viruses including Cryptosporidium and Giardia without adding chemicals. UV is placed after RO storage and immediately before the fill nozzle so recontamination in the storage tank cannot reach the customer. Lamp hours are logged, and our control boards trigger an alarm before UV output falls below spec.
What certifications should water store equipment carry for regulatory compliance?
RO membranes and filtration media should be NSF/ANSI 58 certified, and all product-contact materials should meet NSF/ANSI 61 for drinking water system components. Water vending machines in most states also require food equipment certification from NSF International under NSF/ANSI 18. AMPAC USA specifies certified components throughout our water store packages to simplify health department inspections.
How difficult is it to maintain a water store RO system without technical staff?
Our water store systems are designed for owner-operators, not water treatment engineers. Filter changes follow a clear color-coded cartridge system, RO membranes are swapped with standard wrench-off housings, and our control panel shows service-due alerts in plain language. We provide a written maintenance schedule and offer remote monitoring so our team can flag issues before they affect water quality or machine availability.
