Why must water pipes be insulated in colder climates?

Insulating water pipes in colder climates is essential primarily to prevent freezing, which can lead to a range of issues including pipe bursts and disruptions in water supply. When temperatures drop, any water remaining in uninsulated pipes can freeze, expand, and potentially cause the pipes to crack or burst. This not only results in costly repairs but can also lead to a loss of service and water wastage.

Insulation helps maintain a more consistent temperature within the pipes, ensuring that the water stays above freezing. This is particularly crucial in areas where temperatures can fluctuate significantly. By preventing ice formation and maintaining the flow of water, insulation plays a vital role in the operational efficiency and reliability of the water distribution system in colder climates.
