Water ForwardIntegrated Water Resource Plan (IWRP)
●Austin Water is leading the development of a 100 year water plan that reflects our community’s values
●Goal: Ensure a diversified, sustainable, and resilient water future, with strong emphasis on water conservation
●We are seeking your input on the plan
oFocus today is on demand management strategies and supply options

Water ForwardIntegrated Water Resource Plan (IWRP)
● Incorporates planning for drought and climate change
● Council-appointed Task Force meets monthly
● Interdepartmental coordination and coordination with the community to make sure plan is implementable
● Plan projected to be completed in 2018 with planned updates on a five year cycle
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
• Colorado River:
– Combination of State-
granted water rights & long-
term contract with LCRA
– Up to 325,000 acre-feet per
year (afy)
• LCRA reservation & use fees
pre-paid in 1999
– Additional use payments
trigger when average for 2
consecutive years exceeds
201,000 afy

Workshop 1: What we heard
We’re moving in the right direction
Want to see return
on investment
Reliability is important
Affordability and equity
are important
Balance short term and long
term planning
Concern about climate
change
Support for distributed
and demand management
options
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Targeted stakeholder outreach meetings
• Series of three stakeholder meetings held in January
2017 to discuss demand management options
focusing on:
• Landscape transformation and irrigation
efficiencies
• Alternative water ordinances and incentives
• Development and plumbing ordinances and
incentives
• Brought in landscaping, irrigation, and plumbing
industry experts, large volume water users,
environmental groups, development community
representatives
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
How Public Input will be Incorporated
• Understanding of values and perspectives of what is important
• Feedback on demand-side and supply-side options
• Feedback on plan recommendations and path forward
• Gauge overall understanding of plan for communication/outreach efforts
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Disaggregated Demand Model
● Demand forecast driven by many different factors
● How we use water in our homes and businesses
● Weather
● Conservation
● Population growth

Planning for Droughts Worse than the Recent Drought
• In the past, the worst drought in the region occurred during the 1950s
• The most recent drought from 2007-2016 eclipsed the 1950s drought
• Inflows in the worst year in the recent drought were 2.5 times lower than what they were in the worst year of the 1950s drought
• Our modeling shows that droughts worse than the 2007-2016 drought are possible

IWRP Development Process
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Demand Management Options
Water Loss Control – reducing water losses in AW’s water distribution system through strategies like leak detection, reducing main break response time, and performing water main replacements
Automated Metering Infrastructure (AMI) – New meters that provide real time information on customer water use to help encourage efficient water use and identify possible home leaks or other high uses of water that can be corrected by the homeowner
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Demand Management Options
Landscape Transformation – ordinances and/or incentives to encourage changing turf to more water efficient landscaping or limit the amount of turf on properties.
Irrigation Efficiency – ordinances and/or incentives to encourage the use of water efficient landscape irrigation systems
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Demand Management Options
Commercial/Institutional/Industrial Conservation – ordinances and/or incentives to encourage more efficient water use for cooling towers/boiler feeds, AC condensate recovery, swimming pools/decorative fountains, as well as disclosure of inefficient water use fixtures at point of sale
Plumbing Fixture Efficiency – ordinances and/or incentives to encourage use of Energy Star and WaterSense labeled equipment, and for replacement of non-water efficient plumbing fixtures
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Demand Management Options
Onsite Reuse of Water for Non-Potable Uses –ordinances and/or incentives to encourage onsite rainwater harvesting, greywater systems, and dual plumbing (for new developments) in order to reduce the use of drinking water for landscape irrigation and toilet flushing
Water Use Benchmarking – programs to encourage water efficiency benchmarking for new developments and reporting of water use for large building owners
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Demand Management Options
Customer Education/Outreach – programs that continue to educate AW water customers on the conservation and value of water
Water Rates/Water Fees – explore how changes in water rates and water fees may further encourage water use efficiency while maintaining affordability and equity
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Supply Options
Expanded Reclaimed Water System – expansion of AW’s “purple-pipe” reclaimed water system for non-potable uses like irrigation, cooling towers, and toilet flushing
Decentralized Options for Wastewater Reuse –use of neighborhood satellite wastewater plants or onsite (building-scale) wastewater treatment for non-potable uses like toilet flushing, cooling towers, and landscape irrigation
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Supply Options
Indirect Potable Reuse – various strategies to transport highly treated reclaimed water via natural systems like surface water reservoirs or alluvial aquifers for purification to drinking water quality at an existing water treatment plant
Direct Potable Reuse – Purifying highly treated reclaimed water using advanced treatment (similar to desalination treatment) to supplement drinking water supply
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Supply Options
Rainwater and Stormwater Capture – capture and storage of rainwater and stormwater for various uses like irrigation and toilet flushing (neighborhood-scale)
Aquifer Storage and Recovery – storing excess surface water during wet years in underground aquifers for later use during dry years
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Supply Options
Additional LCRA Supply/Enhanced Lake Operations/Capture of Stormwater Inflows –additional LCRA supply and various strategies at Lake Austin and Lady Bird Lake to increase ability to draw water from reservoir storage and minimize lake evaporation during dry years
Enhanced Off-Channel Storage at Walter E. Long Lake – if Decker Power Station is taken off line, Decker Lake could be used for additional storage that could provide additional water during dry years
Water Forward – Austin’s Integrated Water Resource PlanFebruary 8, 2017
Preliminary Supply Options
Groundwater – includes brackish groundwater desalination (removing salts from brackish groundwater using advanced water treatment for new water supply) and conventional groundwater options
Seawater Desalination – removing salts from ocean water using advanced water treatment for new water supply

IWRP Guiding Principles● Recognizing that Colorado River water is Austin’s core supply, continue a strong
partnership between the City and LCRA to assure its reliability
● Focus on conservation and water use efficiency
● Strengthen long-term sustainability, reliability, and diversity of Austin’s water
supply through maximizing local water resources
● Avoid severe water shortages during times of drought
● Focus on projects that are technically, socially, and economically feasible
● Continue to protect Austin’s natural environment
● Continue to meet/exceed all federal, state and local public health regulations
● Align with Imagine Austin’s “Sustainably Manage Our Water Resources Priority
Program”
● Maintain coordination and communication with regional partners
● Engage the public and stakeholders throughout the plan development process

Planning for uncertainty and change: Droughts
• 2011 the lowest amount of water flowing into the Highland Lakes since they were built
• In a February 2015 press release LCRA announced that:
…“the Highland Lakes are now in a new ‘critical period’ marking the driest conditions on record, eclipsing the 1947-57 drought that until now was the worst on record for this region.”
