AWWA Virtual Conference: inform. influence. impact

We’re excited to be sponsoring, and presenting at, the American Water Works Association ACE21 virtual conference where ideas will be exchanged and innovation explored. 

Our ACE21 Conference Sessions

Monday, June 14 

Water Quality  
HDR Sponsored Session | 12:15 – 1:15 p.m. (CDT) 
The City of Issaquah, WA’s experience with PFAS Removal  

  • Moderator: Christina Alito  
  • Presenter: Beth Mende 

This session will provide an overview of the City of Issaquah’s management of PFAS in groundwater wells, including expedited design and construction of a Granular Activated Carbon treatment system. The project team is currently evaluating several years' worth of GAC operational data to further understand operational cost of PFAS treatability. 

Tuesday, June 15  

The Many Facets of Biological Treatment  
Water Quality: Challenges and Research | 12 – 12:45 p.m. (CDT) 
Biological Active Contactors: Augmenting Drinking Water Membrane Treatment for Enhanced Taste & Odor Control | 12:20 p.m. (CDT) 

  • Author: Chance Lauderdale  
  • Co-Author: Christina Alito 

Leveraging bioactivity in non-filtration WTP applications remains relatively limited. Indeed, facilities that achieve filtration with low-pressure membranes, in lieu of traditional granular media, sacrifice potential benefits from bioactivity and often rely on the application of non-sustainable chemicals to treat dissolved contaminants. An alternative to this practice is to integrate a biologically active roughing contactor into the existing treatment train. We'll review this emerging approach, including fundamentals, a case study on T&O removal, operational and design considerations, and cost implications. 

Successful Water Main Condition Assessment Programs 
21st Century Infrastructure | 12:45 – 1:45 p.m. (CDT) 
Three Pipelines, Four Condition Assessment Technologies: A Case Study to Improve Renewal Decision Making and CIP Planning | 1:05 p.m. (CDT) 

  • Author: Eric Scherch 
  • Co-Author: Dan Ellison 

Learn how to plan and execute potable water pipeline condition assessment to identify actionable results and timing for future CIP and condition assessment projects. We'll present a condition assessment project that includes assessment of three different steel pipelines using four different condition assessment technologies. The condition assessment and identified CIP improvements from this project resulted in a significant return on investment for ratepayers and lessons learned for future pipeline asset management and condition assessment programs. 

Successful Water Main Condition Assessment Programs 
21st Century Infrastructure | 12:45 – 1:45 p.m. (CDT) 
GLWA WRF Tailored Collaboration Project: Management of PCCP to Extend Asset Life | 1:25 p.m. (CDT) 

  • Co-Author: Susan Donnally 

We’ll present the status of Great Lakes Water Authority’s Water Research Foundation Tailored Collaboration Project 5069, “Managing Prestressed Concrete Cylinder Pipe to Extend Asset Life.” The  GLWA is undertaking a new and comprehensive Linear System Integrity Program evaluation of its over 800 miles of large-diameter water transmission system assets. As part of this effort, GLWA is supporting the Tailored Collaboration Project. We’ll describe how the funded research project is helping to inform GLWA LSIP efforts and outline our findings to date.

Utility Management and Planning in a Climate of Uncertainty  
Water Utility Management and Leadership | 12 - 1 p.m. (CDT) 
Sing a Programmatic Approach to Plan, Realign, and Deliver Amidst Uncertainty | 12 p.m. (CDT) 

  • Author: Karen Pappas  

"Drought and pandemic and wildfire, Oh My!" The City of Santa Cruz Water Department has embarked on a 10-year Program to deliver water system resiliency and secure water supply reliability during a time when it seems that the only constant is uncertainty. This presentation demonstrates how the City has navigated from planning into implementation, providing an overview of the tools and practices used to control program risks, realign delivery in response to challenges, and effectively coordinate staff and consultants to ensure success. The Program’s 22 projects effectively touch every aspect of the City’s backbone water infrastructure, from source to treatment to delivery, plus supply augmentation.
