Water Forward A WATER PLAN FOR THE NEXT 100 YEARS FY 2019-2020 Annual Report W A T E R F O R W A R D INTRODUCTION This report documents Austin Water’s progress made during Fiscal Year 2019-2020 (FY20) to implement the Water Forward plan. Despite challenges posed by the COVID-19 pandemic, staff made considerable progress on near term Water Forward strategies as described in the following pages. Water Forward is the City of Austin’s 100-year integrated water resource plan developed to create a resilient and sustainable water future in the face of challenges posed by population growth, climate change and droughts worse than those we have experienced in the past. The Austin City Council adopted the Water Forward plan in November 2018. Austin Water (AW) led the development of the plan using a One Water approach that balances multiple objectives including water reliability, social, environmental and economic benefits. The plan’s guiding principles (listed to the right) were crafted in collaboration with the Council-appointed Water Forward Task Force to reflect our community’s values and continue to inform current implementation efforts. AW is also working to understand and consider equity and affordability impacts in implementing the plan. The Water Forward plan includes strategies to reduce potable water demand, increase the use of alternative and reclaimed water, protect our core Colorado River and Highland Lakes supplies, and build potable supply resiliency during future droughts with strategies like Aquifer Storage and Recovery (ASR). AW is leading the implementation of the plan and continues to work with the Water Forward Task Force and other City departments. Current implementation efforts include onsite reuse and reclaimed water code changes, development of conservation programs, working with our regional partners to protect our core supplies, and procuring a consultant to assist in the identification of potential ASR pilot locations and future ASR program management. The utility is also continuing to engage the community to develop the relationships and resources necessary to support the plan implementation process. 1This annual report covers the period from October 1, 2019 to September 31, 2020, which aligns with the City of Austin fiscal year. Many AW performance metrics, including gallons per capita per day (GPCD), are reported on a fiscal year basis. Some metrics that AW reports to other agencies including Texas Commission on Environmental Quality (TCEQ) and Texas Water Development Board (TWDB) are tracked on a calendar year basis from January 1st …

Do you have any concerns about the City's future supply of water? (open text) Prior to this survey, were you aware of the ASR project? ASR is a water supply strategy to store water in a natural aquifer when it is available during wet times and supply stored water to customers in times when water is needed. Does this description help you understand the meaning of ASR? How could we better describe ASR? Based on your current knowledge, do you have any concerns about the ASR project? Please rank the ways that COA will benefit from ASR in order of importance to you. 10. Please select your top 3 preferred communication methods, to be used by AW.
