Raw water source for NFPA 13R systems is typically sourced from what kind of source?

• A. A municipal treated water line
• B. A private well chemically treated
• C. A natural source such as a river
• D. A cistern used for irrigation

Answer: (C)

Raw water for NFPA 13R is typically drawn from natural, untreated surface water sources, such as a river. In many low-rise residential settings where a municipal treated line isn’t available or practical, the sprinkler system can be fed from a nearby natural body of water, stored and pumped to the system as needed. This contrasts with treated potable supplies or irrigation cisterns, which aren’t considered raw water sources for the sprinkler system. So a natural source like a river best fits the idea of raw, untreated water used for NFPA 13R.
