A high flow rate with corrosion of pipes is a significant concern in water distribution systems because it can lead to the leaching of harmful metals and contaminants into the drinking water. Corroded pipes, especially those made of iron or lead, can release heavy metals and particulate matter into the water supply, which poses health risks to consumers. Additionally, high flow rates can exacerbate the turbulence within the pipes, further increasing the potential for erosion of pipe material and sediment disturbance.

Maintaining optimal conditions within the distribution system is crucial to ensuring water quality. When water flows at elevated rates, it increases the likelihood of contact between the water and any corroded surfaces, facilitating the introduction of contaminants. Regular monitoring and maintenance, including assessing pipe conditions and flow rates, are necessary to mitigate these risks and protect public health.
