Needed fire flow (NFF) is the amount of water that should be available for providing fire protection at selected locations throughout a community. We have prepared a guide for estimating NFF. The publication requires knowledge and experience in fire protection engineering for its effective application.
You can download a copy of the Guide for Determination of Needed Fire Flow. The document is a PDF file of approximately 90KB. You can view or print the file with a free Adobe® Acrobat® Reader.
