What is a critical requirement for pipes used in water distribution?

A critical requirement for pipes used in water distribution is durability and maximum corrosion resistance. Water distribution systems need to reliably transport water over long periods without failure, making the materials from which the pipes are made essential to their longevity and effectiveness.

Corrosion is a significant issue for pipelines, especially those that carry drinking water, as it can compromise the structural integrity of the pipes, leading to leaks or bursts. Therefore, materials that resist corrosion, such as ductile iron, PVC, or specially coated steel, are imperative. These materials ensure that the pipes can withstand the harsh conditions of the environment and the chemical properties of the water being transported.

While lightweight materials can make installation easier and low cost might seem attractive, those characteristics don't address the long-term durability and integrity needed for a water distribution system. Also, while aesthetic value can be appreciated in some contexts, it is not a foundational requirement for pipes, since their primary function is utility rather than appearance.
