ASESSING CONSEQUENCES?
CONSIDER THE TRIPLE BOTTOM LINE
SLIDE 11
CALCULATING CRITICALITY
COF= COST OF FAILURE Redundancy Factor = RF Criticality = POF X COF X RF
SLIDE 12
WAYS TO REDUCE RISK
Routine & Preventative Maintenance Redundancy Spare Parts Specialized Training Replace Assets Early Monitoring
SLIDE 13
ASSESSING CRITICALITY: A SIMPLE EXAMPLE
SLIDE 14
FACTORS TO CONSIDER FOR
Age of Well Condition of Well Clogging of Well Aesthetic Water Concerns Depth of Well
PROBABILITY OF FAILURE

DOES IT MAKE SENSE? DO YOU CARRY TOO MUCH RISK, NOT ENOUGH OR JUST RIGHT?
What does the data say?

CRITICALITY IS NOT STATIC EACH DAY CRITICALITY CHANGES SLIGHTLY NEED TO REASSESS CRITICALITY AT LEAST EVERY YEAR IF NOT SOONER REASSESS WHEN MAJOR CHANGES ARE MADE (UPGRADES, REPLACEMENTS, MAJOR CONSTRUCTION, REHABILITATION, REDUNDANCY ADDED)
CRITICALITY CHANGES
