Why Is This Important?
This measure tracks the annual number of service outages over 12 hours associated with the Portland Water Bureau (PWB) owned service lines that carry water t o customers from the water mains (usually up to the property line). This measure helps PWB track the long duration (over 12 hours) service outages. This measure also helps PWB to indirectly track the condition of these assets (as outages are often associated with asset conditions) . If the service line failures increase over time, this would indicate the need to replace the service lines earlier.
