What are some auxiliary water supply sources for sprinkler systems?

The auxiliary water supply sources for sprinkler systems include various methods or facilities that can provide additional water when the primary supply is insufficient. Manually activated fire pumps are effective because they can be engaged to boost water pressure during a fire emergency, ensuring that the sprinkler system operates effectively. This is especially important in situations where the municipal water supply may be inadequate or compromised.

Automated sprinkler heads, while part of the sprinkler system itself, do not serve as a water source; they are components that distribute water. Rainwater harvesting systems and groundwater wells may offer additional water supplies, but the option of manually activated fire pumps is more directly tied to the function of enhancing an existing sprinkler system in immediate fire situations. This is why they are recognized specifically as auxiliary sources for sprinkler systems.
