Fire Camps
The water supply for stationary fire pumps is a critical component of any fire protection system and is regulated by NFPA 20 (2025). According to the standard, the source of water must be evaluated prior to installation to ensure it meets the requirements for quality, quantity, and pressure.
The ideal standard is for the water supply to support 150% of the rated flow of the fire pump at the lowest permissible suction pressure; however, if this is not achievable, it must provide at least 100% of the rated flow or meet the maximum demand of the fire protection system under those conditions.
Acceptable sources range from public service mains and clean water stored in closed tanks to other sources that meet the fire pump manufacturer’s specifications for water quality. Notably, water sources containing salt or other detrimental materials should be avoided.
For installations drawing from wells or wet pits, the minimum water level must be based on pumping at not less than 150% of the pump’s rated capacity. Ultimately, the authority having jurisdiction (AHJ) plays a crucial role, determining whether the water supply is dependable and suitable to meet the requirements for fire protection.
Ensuring compliance with these guidelines is essential to promote reliability and effectiveness in emergency response situations.
