Water Sector Background

Utilities:

• 53,000 Community Drinking Water Systems

• 16,000 Wastewater Systems

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

4

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

• Reference guide for using Framework

• Key concepts and actions for each element

• Resources that support pursuing actions

6

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

Reduced groundwater recharge

Stormwater management challenges

Increased residential demand

Earlier spring runoff

Lower reservoir levels and water

shortages

Degraded water quality and treatment challenges

Increased frequency and extent of floods

Loss of wetlands and coastal ecosystems

Coastal flooding from storm surges

Saltwater intrusion into coastal

aquifers

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 combinedwith decreased precipitation

– Changes in surface water quality– Changes in demand for water and energy

10

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

11

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

12

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

Adaptation Strategies Guide

19

Promoting a Clear Understanding of Adaptation Options

Overview

• 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

20

Updates

• 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

21

Extreme Weather Events Workshop Planner

22

Developing long term plans to increase resiliency

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 23

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 24

Resources for Planning a Response to Climate Change

Toolbox

26

• Searchable database for utilities to obtain resources related to climate change and water

• Searches by utility attributes, climate concerns, and response strategies selected by the user

• Current version contains approximately 600 resources– Publications– Current activities– Funding opportunities– Events– Tools and models
