How to choose a commercial water system

Commercial systems are sized by daily output and installed on a dedicated water line, often with a storage tank and a booster pump. This collection covers commercial and light-commercial reverse osmosis from 200 GPD to 24,000 GPD, UV systems, whole-building filters and bottleless water coolers for staff and customers.

Who it is for

Restaurants and cafés, offices, gyms and studios, labs and light manufacturing, and any site that would rather own its water treatment than buy bottled water.

What to compare

  • Daily output (GPD): add up every use, from drinks and ice to cooking and equipment, and choose a system rated above that total so it is not running flat out.
  • Feed water: city water and well water need different pre-treatment. Have a recent water test ready when you request a quote.
  • Storage and pressure: most commercial RO systems pair with a storage tank and a repressurization pump so water is available on demand.
  • Footprint and power: check the dimensions and electrical requirements on the product page against your space.

Every system here ships by freight. Send us your delivery address and daily water need and we reply with the system price and freight in one quote.
