• City water plant
pumping & treating
608k gallons/day
• Water used by
citizens 517k
gallons/day
• 15% loss/day due
to leaks in the
system
• Once leaks were fixed,
the plant pumped 124k
gallons/day less
• 20% reduction equates
to 24 gallons/day
reduction by each of
the 5200 residents

• Worst road

counties in Oregon
• More roads in Fair
& Poor condition
than Good or
Satisfactory
• Federal forest
funding
disappearing
What Do These Agencies Have in Common?
• Inadequate funding for preserving asset
conditions
• Primarily “reacting”
• Didn’t have the information needed to “tell their
story”
• A champion initiated a different way of doing
business
Different Way of Doing Business
 Increase service life
 Improve performance
 Preserve asset value
 Reduce annualized costs

• Sample network distribution
– Initial distribution: 25 mi in good, 50 mi in fair,
and 25 mi in poor
• 20 year repair cycle = 5%/year = 5 mi/year
• Deterioration cycle
– 10% deteriorate each year from good & fair
• Scenario 1: Fix roads in poor condition
• Scenario 2: Fix some roads in poor &
some in fair
Scenario 1: 100% Poor

What is Transportation Asset
Management?
A strategic and systematic approach to
managing transportation infrastructure. It
focuses on business and engineering
processes for resource allocation and
utilization, with the
objective of better decision making
based upon quality information and
well-defined objectives

A Strategy For Every Agency
• Tools are available to help any agency
move forward with asset management
concepts
• Agencies should start simply and build
