In which scenario would a fire hydrant not be the best source of water supply?

A fire hydrant may not be the best source of water supply during a drought because, in such conditions, water availability is severely limited. Droughts can lead to reduced water levels in municipal systems, affecting both the pressure and the volume of water that can be drawn from hydrants. While hydrants are typically designed to provide a reliable source of water, their effectiveness decreases when the local water supply is stressed due to drought conditions. This scenario emphasizes the importance of understanding local water sources and their reliability in various environmental situations.
