How can seasonal temperature changes affect water distribution systems?

Seasonal temperature changes significantly impact water distribution systems in various ways. The correct answer highlights key factors: changes in water demand, pipe expansion, and potential freezing issues.

Firstly, temperature fluctuations can directly cause changes in water demand. For instance, during hot months, people may use more water for activities like irrigation, cooling, and increased personal consumption. This shift necessitates that water distribution systems adjust accordingly to meet the higher demand.

Additionally, pipes and other system components undergo physical changes due to temperature variations. Materials like PVC and metal pipes experience expansion and contraction as temperatures rise and fall. This can affect the integrity of pipes and joints, potentially leading to leaks or breaks if the systems are not designed or maintained properly to accommodate these changes.

In colder temperatures, the risk of freezing becomes a significant concern. Water in pipes can freeze, leading to blockages and bursts when the ice expands. This necessitates vigilance from water system operators, especially in areas prone to severe winter weather, to avoid costly repairs and ensure a reliable water supply.

Other choices do not encapsulate the multifaceted effects of temperature changes on water distribution systems. For example, while seasonal changes can impact chemical properties, this is only a narrow aspect of the broader effects. Stating temperature changes have
