Why are main breaks often more prevalent in older systems?

Main breaks are often more prevalent in older systems primarily due to material degradation and increased pressure from modern demand. Over time, the materials used in older water distribution systems, such as cast iron or lead, can corrode, become brittle, or deteriorate, which diminishes their structural integrity. Consequently, these weakened pipes are more susceptible to breaking under stress.

As urban areas expand and populations grow, the demand for water increases. Older systems were typically designed to handle the water needs of a smaller population and may not be equipped to manage the elevated pressures required in contemporary usage. When these systems experience increased pressure from higher demand, the combination of material wear and excessive pressure can lead to more frequent main breaks. This highlights the importance of recognizing that aging infrastructure requires careful management to mitigate the risk of failures and ensure reliable operation.
