Countering an EpidemicStreet Light Copper Wire Theft

-Industrialization of China Picture-Rising market costs of copper picture-Rising appetite for copper
How it all started?

Results of our Initial Theft Deterrent Measures
Cost of Copper Wire Theft
8
Introducing Aluminum Alloy Wire• Acceptable electrical conductor
• Integrates with existing street lighting infrastructure
• Marginal recycling value
• Difficult for thieves to recycle
• Lower capital cost to install
9
Developing a Business Case-Our Team
10
• Learning Objectives• How best to complete the work • Identify the unknowns, i.e. installation
issues• Cost to complete• Time required• Recycling• What’s our return on investment period
Completing a Trial Run “ The Pilot Project”
11
Pilot Project- What we Learned
Data Gaps
12
Data Gap Solution
3,765 Street Light Record Drawings added to our GIS Database
13
Pilot Project- What we LearnedSplicing Requirements
• Challenges of connecting aluminum wire to copper wire
14
• ‘Jammers’• ‘No-pulls’• Plexed v. non-plexed wiring
Pilot Project- What we Learned
15
• $8.5M Estimated cost to replace street light copper wire with aluminum alloy wire. Return on Investment is 4 years• Will take approximately 2 years to complete based on
an average 3km a day production
Business Case Conclusion
16
• One contract issued for entire copper wire replacement project• Bonus Clause to encourage early
completion – “win – win”• Extensive Public Awareness Effort• Strategic roll out of the replacement
program to target high theft areas first
City Wide Replacement Program
17Cheaper than expected, $6.5M cost vs $8.5M estimate
Results - SUCCESS!

Project Start Date

• Aluminum less susceptible to wire theft than copper• Lower recycling cost, and difficult to
recycle alloy wire• May not be viable for all Cities, target
high theft area’s instead.• Consider installing aluminum wiring for
new street light applications
Approach worth Replicating?
