Report 10.1 Cost of Service Study Rate Design

COUNCIL MEETING
Cost of Service Study
Rate Design Review
Meeting Date: 05/20/14
Agenda Item #: 10.1
Report Purpose
To present Council with recommended changes to the water rates through the completed Cost
of Service Study (COSS).
Recommendation
THAT Council approves changing the 2015 water rate structure by:
i.
Consolidating the Sherwood Park, Ardrossan and Josephburg volumetric
rates into one consolidated hamlet volumetric rate;
ii.
Consolidating the Tamarack, Half Moon Lake and Ardrossan truck fill
rates into one consolidated truck fill volumetric rate; and
iii.
Consolidating the Country Residential and Expanded Services Area one
and two volumetric rates into one consolidated rural volumetric rate.
Council History
July 6, 2010 – Council received the Utilities Department Performance Review Final Report as
information.
October 23, 2012 – Council endorsed, for analysis purposes only, the following pricing
objectives for water rate design:
i.
Very Important: Financial Sufficiency, Equity, Rate Stability
ii.
Important: Revenue Stability, Conservation, Affordability
iii.
Less Important: New Customer Contributions, Customer Impacts, Simple to
Understand, Economic Development, Ease of Implementation
Council directed Administration to proceed with analysis of a proposed water rate structure to
restructure our customer classes to a consolidated Hamlet Rate, Truck Fill Rate and Rural Rate
and report back to Council with the impacts of the potential changes.
Strategic Plan Priority Areas
Economy: Water rate structure can help to ensure funding is available for sustainable
municipal infrastructure. Water rates structure can be a factor for commercial and industrial
development.
Governance: n/a
Social: Water rates structure impacts a resident’s cost of living.
Culture: n/a
Environment: Water rate structure can help encourage water conservation and reduce water
demand which would benefit the environment.
Other Impacts
Policy: n/a
Legislative/Legal: n/a
Interdepartmental: n/a
Summary
April 15, 2014 – The Priorities Committee was updated on the progress of the Cost of Service
Study (COSS) for water services.

Step 4: Design Rate Structure

Fixed Charges
 Invariant with customer water usage
 Cost-of-service fixed charges reflect customer
service costs (e.g. billing, water meters)
 Fixed charges may include portion of capital
costs

Variable Charges (‘Consumption’ Charges)
 Vary with amount of water used
 Recover utility costs that vary with customer
usage patterns

Proposed Rate Design
Hamlets
Current Structure
Proposed Structure
•Three customer classes (Sherwood
Park, Ardrossan and Josephburg)
– Similar fixed charge for metering
and billing
– Different volumetric charges
• One customer class (Sherwood Park,
Ardrossan and Josephburg)
– Similar fixed charge for metering and
billing
– Same volumetric charge based on a
similar service level (pressurized
water system)

Truck Fill Customers

Proposed Rate Design
Truck Fill
Current Structure
Proposed Structure
• Two customer classes (Sherwood Park Truck
Fill) and rural (Ardrossan and Half Moon
Lake)
-Different volumetric charges
• One customer class
-Same volumetric charge based on similar
level of service

Rural Customers

Proposed Rate Design
Rural
Current Structure
Proposed Structure
• Three customer classes (Expanded Service
Area 1, Expanded Service Area 2 and Rural)
-Different fixed charge based on cost of
service
-Different volumetric charges
• One customer class
-One consolidated fixed charge for
Expanded Services Area 1 and 2
-Rural (County Residential) fixed charges
unchanged
-Same volumetric charge based on similar
service level

Conservation
• Current rate structure and other conservation initiatives are working
to meet water consumption targets as described in the Strathcona
County Water Conservation, Efficiency and Productivity Plan (2012).
• Consolidation of eight rates to three rates will have significant
customer impacts.
• Utilities to revisit conservation rate as part of next Cost of Service
Study (est. 2019).

Next Steps
– Wastewater cost of service study to begin in 2014
– Review Utility Reserve Policy in coordination with Financial
Services
• Current State
– Capital reserve
– Operating Rate Stabilization
• Potential options
– Capital reserve
– Asset Management reserve
– Operating Rate Stabilization reserve
– Dividend to municipality
