State Drinking Water Agencies and How NSF/ANSI 61 Might Affect You (Part 3)

In this blog we look at how NSF/ANSI 61 certification differs by state and how that impacts tanks and drinking water components throughout the United States.

Regardless of your geographic location, Poly Processing is committed to ensuring that our polyethylene storage tank systems are NSF/ANSI 61 certified. So no matter where you are, we can meet your state’s regulations.

In this series so far, we've discussed NSF/ANSI 61 and what it means to be certified for both tanks and storage systems, and the difference between potable water certification and chemical certification.

In this post, let's look at the way NSF certification differs by state and how that impacts tanks and drinking water.

Regulating Drinking Water Systems

The components that make up drinking water systems fall into two categories of regulation. Centralized water treatment plants and water distribution systems up through the water meter are typically regulated by state drinking water agencies. Water distribution systems downstream of the water meter or inside a building are typically regulated by state or local plumbing codes.

While all major model plumbing codes require the use of NSF/ANSI 61 certified products, the specific requirements for those product types can be found in state or local plumbing codes.

NSF Certification Among the States

Each state has its own law with regards to NSF/ANSI-61 regulations. For example, Title 22 drinking water standards in California have been in adoption since March of 2008. Thus, all products and components utilized in conjunction with drinking water must be compliant with Title 22 regulations. Here is a link to the NSF website that discusses US requirements.
