What does the minimum water supply requirement for a structure depend on?

The minimum water supply requirement for a structure is fundamentally based on the size and construction of the structure. Larger structures or those with specific design features may require more water for firefighting and sprinkling systems to ensure adequate protection and suppression capabilities. For example, a high-rise building or a structure with a substantial occupancy load typically necessitates a more significant water supply than smaller, single-family homes.

Additionally, certain construction materials can influence how quickly a fire might spread or how effectively it can be contained, but they do not primarily dictate the quantity of water needed. Environmental conditions and local water availability are important factors in the broader context of firefighting operations but do not set the minimum water supply requirements for a specific structure. Understanding this relationship is crucial for fire safety planning and ensuring that appropriate water supply systems are in place for different types of buildings.
