Public Drinking Water Equipment Performance

The NSF Guideline for Public Drinking Water Equipment Performance (PDWEP) and NSF/ANSI 419 establish performance requirements in the treatment and production of drinking water, and includes requirements such as the U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR).

Certification under this program demonstrates compliance to federal testing requirements but also adds a unique audit component, to ensure that products are manufactured using recommended methods and processes.

This NSF program applies to equipment used in the treatment or production of drinking water in EPA-defined public water supplies, such as:

• Microfiltration membranes
• Ultrafiltration membranes
• Nanofiltration and reverse osmosis membranes
• Ultraviolet (UV) reactors
• Bag and cartridge filters
• Other products used in the treatment or production of drinking water

Certification to NSF/ANSI 419 covers ultrafiltration and microfiltration membranes as well as bag and cartridge filters. The NSF Certification Guideline for Public Drinking Water Performance covers technologies such as ultraviolet reactors and other products used in the treatment or production of drinking water.
