Despite challenges posed by the COVI-19 pandemic, staff made considerable progress on near term Water Forward strategies  Most of the data in this document was able to be reported on a fiscal year basis. In some instances only calendar year data was available and that has been noted where necessary. Awards & Recognition “The innovations coming to the water sector present an opportunity for a paradigm shift in the way utilities think about and solve long-standing challenges to clean and reliable water,” said Jackie Jarrell, WEF President. “WEF is excited to recognize Austin Water for embracing innovative ways to better serve their communities.” Protecting Our Core Colorado River Supplies Monthly Inflows to Lakes Buchanan and Travis Data through November 30, 2020 Average 1942 - Present Average 2008 - 2015 2019 2020 h t n o M r e p t e e F - e r c A 400,000 350,000 300,000 250,000 200,000 150,000 100,000 50,000 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec My ATX Water Austin’s Smart Water Meter System My ATX Water Implementation Map Existing and Updated Conservation Programs  New Commercial, Industrial and Institutional Water Conservation Ordinances • Added water efficiency standards for drift eliminators in cooling towers and the requirement that biocide be used in the cooling tower recirculating water to increase water efficiency and reduce the potential for airborne bacteria such as Legionella; Imposed administrative penalties for failure to submit required cooling tower registration and annual inspection reports to ensure towers are meeting all water efficiency standards and equipment requirements; and • • Made ineligible for evaporative loss credit on the wastewater bill, facilities with cooling towers for which required registration and inspection reports are not submitted.  New and Revised Water Conservation Incentive Programs • Added new measures and equipment for residential and commercial irrigation system efficiency upgrades and landscape transformation rebates • Added new rebate programs for residential “Laundry to Landscape” graywater reuse and efficient pool backwash • Doubled rebate amounts based on new cost/benefit benchmarking information contained in the 2018 Water Forward cartridge filters Plan • Streamlined the rebate application review and approval process Alternative Water and Conservation Ordinances Phase I to take effect late 2020/early 2021 Phase 2 targeted to take effect 2023/2024 Voluntary OWRS Program  New OWRS regulations in Title 15 (Utility Regulations) for the design, permitting and operation and maintenance of multi-family & commercial systems Mandatory OWRS Program  Mandatory installation of OWRS for commercial and multi-family developments >250,000 sq. ft. in Title 25 (Land Development Code)  Rules will be posted on the applicability for the mandate along with provisions for enforcing the mandate Alternative Water Incentives  Pilot grant program developed  Projects reusing >1,000,000 gallons per year of water are eligible for $250,000  Projects reusing >3,000,000 gallons per year of water are eligible for $500,000 Onsite Water Blackwater Reuse Pilot OSCAR (On-Site Collection and Reuse) and CLARA (Closed-Loop Advanced Reclaimed Assembly) Water Use Benchmarking Centralized Reclaimed Decentralized Reclaimed  Staff re-evaluating long- range infrastructure planning processes to better identify and integrate opportunities for decentralized reclaimed Preliminary Draft Conceptual Areas for Further Study Aquifer Storage and Recovery FY20-23: Initial contract and identify where to pilot FY28-29: Preliminary engineering for full-scale ASR FY31-35: Construction of full- scale ASR 2020 2025 2030 2035 FY24-27: Design, construct, and test ASR pilot. Develop recommendations for full-scale ASR FY29-30: Design for full-scale ASR Metrics • Future projections and targets are as reported in the adopted 2018 Water Forward plan. • Savings and yield targets will be updated starting with the 2023 Water Forward plan update to reflect strategy implementation progress and improvements to strategy savings and yield estimates. Looking Forward  Continued community and stakeholder engagement  Further study to inform the implementation of a future Indirect Potable Reuse project  Anticipated completion of the Centralized Reclaimed Water Master Plan  Preliminary analyses to support updates to the Water Forward Plan, to be completed in 2023 QUESTIONS
