Pure Aqua, Inc. designs and manufactures water treatment systems in addition to tap water reverse osmosis systems. These reverse osmosis machines were completed in April 2013 with the intention of being used in a manufacturing process in Canada. The three machines all were created to purify tap water but can be used for well water occasionally. Two of the tap water reverse osmosis systems are capable of producing 9,000 gpd while the third system is capable of producing 7,200 gpd.
