Aquifer Storage and Recovery (ASR) Pilot and Program Management – Phase 1a James Dwyer & Kristi Shaw - HDR Water Forward Task Force | May, 7th, 2021 Scope Basis SUCCESSFUL ASR PROJECT areas and implementation challenges  Understand the candidate aquifer  Consider integration of the ASR supply into the existing distribution system preferred project alternatives  Use proven decision tools to identify  Develop mindful outreach strategies to educate and engage the community Task 4 • Initial storage zone screening • Heat mapping of aquifer characteristics • Key outcome: potentially suitable ASR wellfield areas Task 5 Task 8 • Integration point scoring using criteria • Key outcome: potentially suitable integration points • Develop plan and budget for field testing • Key outcome: Exploratory Drilling & Testing Plan Task 1. Task 2. Task 4. Task 5. Task 6. Task 7. Project Management AW and Consultant Team Chartering Preliminary ASR Storage Zone Identification & Characterization Preliminary ASR Integration Point Identification and Characterization Preliminary Project Alternatives Development & Evaluation Project Alternatives Revision & Re- evaluation Task 8. Exploratory Drilling & Testing Planning Task 6 • Use suitable wellfield areas & integration points to develop project alternatives Task 7 • Final report • Project alternative revision as needed • Score each alternative using project criteria • Key outcome: preferred project informed by community input alternative(s) • Key outcome: scored project alternatives Task 3- Community Engagement and Education, including equity and affordability tasks Overview of Phase 1a Project Approach Task 2 –Team Chartering  Goal: support clarity of mission and tenets of success, and project team alignment  Steps: • Project initiation chartering • Follow-up chartering sessions to realign goals and objectives as needed, particularly as a result of community engagement Task 3 – Community Engagement Consultant Community Engagement Team: ✓ ✓ ✓ ✓ Kristi Shaw, HDR Technical ASR- Communications Liaison Carmen Schofield, HDR Communications Lead Shuronda Robinson, Adisa Communications Advisor- ASR Introduction and Education Task Lead Lynda Rife, Rifeline Advisor- Outreach and Preliminary Project Alternatives Public Engagement Task Lead Task 3 – Project Introduction, Engagement, & Education Engagement and Education Plan Introduction and Education Campaign  Project background, goals and objectives  Introduce the project to the community  Identify roles and responsibilities within  Demonstrate how ASR fits into Water Forward project team  Identify project milestones and schedules  Identify communities and stakeholders, including governmental entities, regulatory bodies, and public interest groups  Outline Phase 1A engagement strategies  Engage stakeholders, including customers, elected officials, partner agencies, and the media  Develop initial educational campaign and materials for ASR introduction and education Task 3 – Equity & Affordability (E&A) Roadmap  Outline goals, criteria, and metrics that define E&A with an AW and ASR lens  Conduct research on efforts undertaken by similar municipalities  Gather community perspective and feedback through community meetings  Develop final Roadmap to establish best practices and provide E&A strategy Equity and Affordability Tool  Evaluate project alternatives and implementation approaches through an E&A lens  Identify E&A challenges associated with each project alternative and potential strategies to address them  Identify criteria for an iterative evaluation process of project alternatives Task 6. Preliminary Project Alternatives Development and Evaluation Task 7. Project Alternatives Revision and Re- evaluation, as needed Task 3 – Community feedback + evaluation criteria Present draft criteria for evaluation of project alternatives. Gather community input through collaborative workshops and other engagement tools. Task 6.2 Preliminary Project Alternatives Development and Evaluation Task 6.11 Preliminary Project Alternatives Development and Evaluation Task 7.1 Project Alternatives Revision and Re-evaluation Task 7.7 Project Alternatives Revision and Re-evaluation ✓ ✓ ✓ ✓ Share preliminary Task 6 project criteria and weightings Collect input Consider and incorporate input Share refined project criteria and weightings Collect additional input Summarize input provided on refined criteria Consider and incorporate input Present final findings and next steps Final community touchpoint of Phase 1A program Task 4 - Preliminary ASR Storage Zone ID and Characterization  Goal: Screen aquifer units in Travis & surrounding counties to identify potential ASR storage zones (SZs)  Steps: • Define ASR wellfield performance objectives • Perform initial storage zone screening to determine which SZ are scored • Score SZs for aquifer and wellfield criteria • Detailed storage zone criteria mapping ASR Hydrogeological Parameter Scores, TWDB Statewide ASR/AR Assessment County/Aquifer Combinations for Initial Screening: Major Aquifers County/ Aquifer Combinations for Initial Screening: Minor Aquifers Task 5 - Preliminary ASR Integration Point ID & Characterization  Goal: Identify and evaluate potential ASR integration sites • Evaluate normal and drought conditions • Consider future supply availability and demands  Steps: • Define integration point objectives and needs • Nodal needs and availability modeling • Integration point identification and evaluation Task 6 - Prelim Project Alternatives Development & Evaluation  Goal: Develop & evaluate ASR project alternatives • Alternatives combine potentially suitable sites for ASR (Task 4) and integration options (Task 5) • Criteria & weighting will be informed by community engagement and equity work  Steps: • Project alternative criteria & weighting • Conceptual designs and cost estimates for identified project alternatives Task 6 - Prelim Project Alternatives Development & Evaluation (continued)  Major element of Task 6 is engaging the community on what evaluation criteria are used • Seek community input on evaluation criteria and weightings • Refine criteria and weighting, as needed based on community input • Perform project alternative scoring with refined criteria and weighting Task 7 – Project Alternatives Revision and Re-evaluation  Goal: Project alternatives from Task 6 will be revised based on community input and preferred alternative(s) will be identified  Steps: • Community engagement on scored project alternatives • Project alternatives revision • Identification of preferred project alternative(s) • Phase 1a ASR report Task 8 - Exploratory Testing Planning  Goal: Develop testing plan to address uncertainties and key assumptions in Phase 1a ASR evaluation  Steps: • Exploratory Drilling & Testing work plan • Will include estimated costs for field testing • Lessons learned workshop Overall Phase 1A ASR Pilot and Program Management Project Schedule 3.1 Develop Engagement and Education Plan - Phase 1a 3.2 Introduce the ASR Program and provide education 3.5 Develop and Manage Stakeholder Database 3.3 Develop Equity and Affordability Road Map (EARM) (Incorporate findings into EEP) 3.4 Develop Equity and Affordability Tool Task 1.
