According to the latest EPA guidelines, any new or upgraded water purification system must comply with the Clean Water Act and meet certain water quality standards.
According to the EPA, all new or improved water purifying systems must meet the following criteria: 1.
Be a purifier capable of purifying up to 150 gallons per minute of water at a pressure of 6.3 bar, or 15.8 psi, 2.
Have a minimum flow rate of 50 gallons per second, or 5.3 cubic feet per minute, 3.
Be capable of keeping water circulating at a minimum of 30 degrees, or 25 degrees cooler than ambient temperatures, and 4.
Provide a purification pump for use when water is not available for purification.
The EPA defines “purification pump” as an automatic, manual, or manual-controlled water purificator that has a water pressure of 7.1 psi or less.
The EPA recommends that any new water purifieser have a pump that operates at a lower pressure than the required flow rate.
The regulations also require new or renovated water purifications systems to provide a filtration system capable of cleaning up to 10 gallons of water per minute.
The rules also require water purifers to provide at least one of: 1) a filter system capable at least of removing up to 50,000 microorganisms per minute from water, and 2) a filtering system that has been installed and maintained at least 50% of the time during the preceding five years.
New or renovated systems that are not complying with these requirements can be fined up to $250,000.
