Which increased risk results when a municipal water supply encounters prolonged sub-zero temperatures?

💡 Explanation

Pipe bursting risk rises—water volume increases approximately 9% upon freezing because hydrogen bonding forces water molecules into a crystal lattice; it is volumetric expansion rather than change of reaction or ice-dam formation, which don't directly cause failure within the pipe itself.
