Which of the following is a characteristic of a healthy distribution system?

A characteristic of a healthy distribution system is identified by low levels of non-revenue water. Non-revenue water refers to water that is produced but not billed to customers due to various factors such as leaks, unauthorized consumption, or meter inaccuracies. A distribution system with low non-revenue water indicates efficiency, effective management, and minimal losses, which are critical for maintaining water quality and sustainability.

In contrast, high levels of water theft or frequent pipe leaks suggest significant issues within the system, leading to wasted resources and potentially higher operational costs. High maintenance costs can arise from recurring problems typically associated with an inefficient system, whereas a healthy distribution system operates effectively, minimizing the need for extensive repairs. Thus, maintaining low levels of non-revenue water reflects a well-managed and healthy distribution system.
