CRP Regional Water Wastewater Servicing Project

1
CRP Regional Water / Wastewater Servicing Project

• Sub-Regional Information Session
• Service Area C
• Airdrie, AB
• May 23, 2007

2
Overview of Presentation

• Review of Drivers for Project
• Review of Project Objectives
• Growth Scenario Examined
• Overview of Servicing Alternatives
• TBL Analysis of Alternatives
• Next Steps in Project

3
Project Drivers

• Growth
• Water and wastewater infrastructure under
  pressure from rapid growth in region
• New development limited by availability of water
• Questions regarding sustainability and
  environment protection in region
• Growth in region proceeding without a regional
  plan

4
Project Drivers

• Water Availability
• South Saskatchewan River Basin Water Management
  Plan (SSRB WMP) proposes moratorium on new water
  licenses in Bow River Basin
• Water resources available to communities will be
  limited to amount of existing licenses
• Additional water will need to be obtained
  through
• Water license transfers
• Purchase of raw water
• Purchase of treated water
• Groundwater extraction (where applicable)

5
Project Drivers

• Public Health Protection
• Alberta Environment Waterworks Facility
  Assessments revealed that smallest systems at
  highest risk for compliance violations
• Small systems have difficulty attracting and
  retaining qualified operators
• Regional systems identified by Province as a
  means of addressing these concerns grant program
  in place

6
Study Objectives

• Develop sustainable water and wastewater
  servicing solutions for Calgary Region
• Develop technical servicing options
• Infrastructure
• Water management approaches
• Evaluate alternatives using triple bottom line
  decision approach

7
Growth Scenario Examined

• No Regional Land Use Plan in place
• Future growth scenario examined based primarily
  on Calgary Regional Economic Forecast (CREF)
  Transportation Model
• CREF data augmented by community planning
  documents
• Individual developments and ASPs not considered

8
Land-Use Neutral Growth Scenario

• We are comparing the relative merits of
  alternative servicing options for this single
  growth scenario
• Our analysis does not include assessing the
  desirability or nature of the growth
• Coordination needed with Regional Growth and
  Sustainability Framework

9
CREF Model

• Covers all of CRP except Banff, Canmore, MD of
  Bighorn, Nanton, portions of Wheatland County

10
Servicing Zones

• Growth in CREF zones summed and concentrated at
  Service Nodes

11
C 2030 Service Population

• Airdrie 63,500
• Crossfield 3,850
• Rocky View North 4,075
• Rocky View Central 29,823

12
Key Issues Water Availability

• All new developments in MDs and Counties will
  need to obtain water license or external supply
• Without conservation, Black Diamond, Turner
  Valley, High River, Okotoks, and Nanton will
  require additional water licenses
• With 30 conservation, only Okotoks will require
  an additional licence for 30-yr horizon
• Adequate license capacity available on a regional
  basis for 2075 demands

13
Analysis of Alternatives

• Focus of study is to develop a sustainable
  servicing plan
• Alternatives will be evaluated using Triple
  Bottom Line objectives

14
Triple Bottom Line Objectives

• Environmental protect and preserve the local
  environment, minimize adverse impacts on water
  quality, minimize energy usage and conserve
  resources.
• Social - protect public health, result in land
  use and growth patterns that enhance the quality
  of life for residents of the Calgary region.
• Economic cost effective solutions that enhance
  the economic development of CRP member
  communities.

15
Draft Decision Framework
16
Area C Water Alternatives

• Airdrie will continue with regional supply from
  Calgary
• Crossfield will continue with regional supply
  from Anthony Henday system
• Servicing options centered around water supply
  for future growth in MD of Rocky View

17
Area C Water Alternatives

• Supply from Calgary
• Supply from Rocky View Water Co-op WTP
• Supply from Kneehill Regional System

• Rocky View Central 29,823 people

Next Steps

• Communities to review TBL results
• Which alternative best addresses individual needs
  and constraints?
• Coordinate Servicing Study and Regional Growth
  and Sustainability Framework
• Establish servicing partnerships
• Begin preliminary engineering
