Comox Strathcona Waste Management (CSWM) Service – Solid Waste Financial Model
Curtis Jung (AECOM) and Lisa Butler (CVRD)
October 21, 2016
Coast Waste Management Association – 2016 Annual
Conference – Session 7 – Economics of Waste
Presentation Outline
– Background - Why and How was the Model Built?
– Results and Actions - What did the Model Tell Us and What
Did we Do?
– Future Plans – What can we do with the Model?
October 21, 2016 CWMA - CSWM Financial Model Page 2
– CSWM function of
CVRD
– Responsibilities
• Two regional waste
management centres
that serve the Comox
Valley and Campbell
River
• Remote community
waste management
Page 3
– SWMP updated in 2013
• 2013 – Diversion rate – 51%
• Diversion target by 2020 – 70%
October 21, 2016 CWMA - CSWM Financial Model
Background – Why and How was the Model Built?
– Motivation
• Significant capital expenditures
planned in upcoming years
• Recent approval of Solid Waste
Management Plan
– Key Questions: o Is our current funding model
sustainable?
oGiven capital expenditures and
diversion targets specified in
SWMP, what will our future cash
flow look like?

Background – Why and How was the Model Built?
– Objectives
• Determine current and projected cash
• Identify cash flow issues
• Examine alternative means of system financing

2. What are the revenues?
3. Who pays?
1. What are the costs?

Background – Why and How was the Model Built?
– Methodology
• Reviewed CSWM SWMP
• Developed population and waste generation projections
• Mapped system components and flows

Results and Conclusions – What did the Model Tell Us?
– Key Variables for Scenario Testing
• Diversion Rate: 58% and 70% (Status Quo: 51% in 2012)
• Recent approval of Solid Waste Management Plan

Results and Conclusions – What did the Model Tell Us?
• Economies of scale are difficult to achieve – Several Small Pieces!
oTwo Regional Waste Management Centres
oSeveral pieces of waste management infrastructure in remote
communities requiring upgrades or closure in the next 5 years

Results and Conclusions – What did the Model Tell Us?
• System underfunded in the short and long term - additional revenue
source(s) required
o If maintaining existing funding model, breakeven tipping fees required to
fund the system in the long-term in excess of $200/tonne.
oModelled tipping fee increase to $130/tonne (maximum set), then
assessed tax requisition required.

Resulting Actions – What Did We Do and Where Are We
Now?
– In 2013:
• CSWM tipping fee - municipal solid waste - $90/tonne
• Funding Model – 96% Tipping Fee, 3% Tax Requisition

Resulting Actions – What Did We Do and Where Are We
Now?
– 2013 Tipping Rates – Desktop Review

Long Term Financial Analysis – Tax Requisition
– Assessed multiple scenarios to introduce tax requisition
with objectives:
• Limit debt servicing costs
• Increase reserves
• Ensure sustainable funding model
– Tax requisition reviewed by board annually

What’s Next for the Model?
– Regional Organics Composting Facility
– Optimizing the transfer of waste from CR to CV in five
years’ time
– Optimizing the transfer of waste from Gold River, Tahsis,
Zeballos, Sayward
