• Consequence of Failure• ???• ???• ???

Risk Matrix Exercise

12

• Age• Material• Velocity• Depth• Past Work Orders

What Do You Think?

Likelihood of Failure

13

• Public Spaces• High Traffic Areas• Medical / School Facilities• Customers Impacted• Adjacent Infrastructure• Environmental Impact• High Visibility

What Do You Think?

Consequence of Failure

14

• Likelihood of Failure - Age• <10 =0• 10-30 = 1• 30-50 = 2• 50-70 = 4• 70 > = 6

• Likelihood of Failure - Material• ACP = 1.5• CIP = 2• DIP = 1• PVC = 0.5

• Likelihood of Failure – Past Work Orders• 0-5 WO = 1• 5 - > = 2

• Consequence of Failure - Customers Impacted• <10 = 0• 10-30 = 1• 30-100 = 2• 100-1,000 = 4• 1,000 > = 6

• Consequence of Failure – Environmental• Private Property = 0.5• Adjacent Stream = 1• Wetland = 1• Endangered Species = 1

• Consequence of Failure – Medical / School Facilities• Yes = 1• No = 0
