Association of Environmental Authorities

March 12, 2013

Water sector background
Water Sector Background


  • 53,000 Community Drinking Water


  • 16,000 Wastewater Systems

Mission statement
Mission Statement

To provide the water sector (drinking water, wastewater, and stormwater utilities) with the practical tools, training, and technical assistance needed to adapt to climate change by promoting a clear understanding of climate science and adaptation options.

Climate ready
Climate Ready

National Drinking Water Advisory Council Climate Ready Water Utilities (CRWU) Report

Final report provides EPA with recommendations on developing a CRWU initiative to support water sector climate resiliency.

Developing an Adaptive Response Framework

Fundamental guide to build out the concept of a climate ready water utility, integrates with other tools.

Framework document
Framework Document

  • Reference guide for using Framework

  • Key concepts and actions for each element

  • Resources that support pursuing actions

What does CRWU Report Mean for EPA?

  • EPA create and implement a CRWU program

  • Integrate CRWU into existing EPA efforts (e.g., EUM, Climate Ready Estuaries)

  • Coordinate with other federal partners, states, associations, utilities

  • Promote watershed planning and encourage adoption of integrated water resources management

  • Recommends developing adaptive regulatory capacity

Climate change and the water sector
Climate Change and the Water Sector

Degraded water quality and treatment challenges

Lower reservoir levels and water shortages

Stormwater management challenges

Earlier spring runoff

Coastal flooding from storm surges

Reduced groundwater recharge

Increased residential demand

Saltwater intrusion into coastal aquifers

Loss of wetlands and coastal ecosystems

Increased frequency and extent of floods

Increasing temperature
Increasing Temperature

2 ̊F increase in global average temperature has been observed over the last 50 years. Projections indicate continued warming, which leads to changes in water quantity and quality:

  • Reduced water supply when combined

    with decreased precipitation

  • Changes in surface water quality

  • Changes in demand for water and energy

Changing precipitation patterns
Changing Precipitation Patterns

Overall changes in climate will alter the total amount of precipitation (may be less or more, depending on local factors and season), contributing to:

  • Changing lake and reservoir levels

  • Altered groundwater recharge

  • Reduced snowpack and reservoir recharge

  • Changes in water quality (increased turbidity)

  • Greater demand for water for irrigation

Rising sea level
Rising Sea Level

Coastal utilities should be concerned about sea-level rise, which can lead to:

  • Increased flooding associated with coastal storm surges

  • Increased saltwater intrusion into aquifers

  • Accelerated loss of wetlands and coastal ecosystems

Extreme weather events
Extreme Weather Events

More frequent and severe extreme weather events can produce:

  • More frequent and larger extent of flood damage to infrastructure

  • Increased crop loss and more frequent water shortages during drought

  • Property loss and erosion following wildfires

  • Increased damage from coastal storm surges to low-lying utility infrastructure

Climate resilience evaluation awareness tool creat

Climate Resilience Evaluation & Awareness Tool (CREAT)


What can you do in creat
What can you do in CREAT?

  • Explore local climate data

  • Access resources

Build Awareness

  • Collect data and document assumptions

  • Assess potential risks

Assess Risk

  • Compare adaptation options

  • Generate reports to support decisions

Plan Adaptation


  • Integrated training

  • Pre-loaded scenarios

  • Extreme precipitation

  • Energy implications

Adaptation strategies guide

Adaptation Strategies Guide

Promoting a Clear Understanding of Adaptation Options



  • Guide for drinking water and wastewater utilities that have not begun to consider climate change in utility planning

  • Navigate guide like a website

  • Goals:

    • Present easy-to-understand climate science

    • Translate science into impacts to utilities

    • List adaptation strategies related to impacts

    • Assist in the adaptation planning process


  • We are currently updating the ASG to include two new sections

    • Green Infrastructure

    • Energy Management

  • These sections are under review and the new version will be available online within the next 6 months

Extreme weather events workshop planner

Extreme Weather Events Workshop Planner

Developing long term plans to increase resiliency


Extreme weather events workshop planner1
Extreme Weather Events Workshop Planner

  • Walks users through all of the steps of planning, conducting, and evaluating a workshop

  • Goal is to determine actions that a utility or community can take today to become more resilient to more frequent and intense extreme events

Extreme weather events workshop planner2
Extreme Weather Events Workshop Planner

  • Includes 5 scenarios:

    • Flooding

    • Drought

    • Sea Level Rise

    • Wildfire

    • Snowpack Changes

  • Contains customizable materials

    • Scenario presentation

    • Facilitator guide

    • Workshop report template

  • Adaptation is iterative, Workshop Planner encourages participants to continue to work together on extreme event and climate planning after workshop is over



Resources for Planning a Response to Climate Change
