NSF DWTU Guide PDF

This certification guide contains sections on the process flow, frequently asked questions, standards requirements, listing options, a glossary and even a section that includes information on how to work with your suppliers. Both certified and non-certified companies will find the guide to be a useful resource. NSF Certified companies familiar with the process can use this as a training and reference tool for those in the organization who may not be as familiar with the process. These clients may also find tidbits of information they were not aware of.

Non-certified companies will find it very useful in understanding their many options before beginning the process, ensuring that they understand the co-marketing potential after gaining certification. The NSF Drinking Water Treatment Unit Certification Program was first established in the early 1970s.
