ACE 2022
San Antonio, Texas | Jun. 12-15
As the world's premier water conference, ACE provides an opportunity to connect with global water experts in every segment of the water sector. After two years, AWWA is returning to an in-person format where water professionals can come together and learn, connect, and be inspired to solve today’s global water challenges. ACE is also offering a hybrid feature for those who are not able to be physically present, in which the most essential tracks will be streamed.
Sunday Workshop: Proactive Management of Aesthetic Quality to Maintain Consumer Confidence
Even when water systems meet regulatory requirements and have safe water available for customers, aesthetic problems of taste, odor, color, and suspended matter can occur deteriorating the public confidence and trust. Planned and organized by the AWWA's Aesthetic Quality and Perception Committee chaired by Garver Water Practice Leader Zaid Chowdhury, Ph.D., PE, BCEE, this workshop from 9 a.m.-4 p.m. on June 12 will provide water utility personnel such as water quality, public relations, customer service, and regulatory managers need-to-know criteria for better managing and mitigating aesthetic problems in drinking water.
Technical Presentations
2-2:30 p.m.
Using BOR Funded Desalination Research to Evaluate an Innovative ZLD Process Train to Treat Cooling Tower Blowdown
Colorado is challenged by freshwater scarcity and salt accumulation in its watersheds. A significant contributor to salt loading in urban sewer-sheds are the many cooling towers that dot the landscape. To help keep the cooling tower water chemistry within acceptable parameters, a portion of the saline recycled water in the cooling tower is frequently discharged to the local sewer (otherwise known as blowdown) while potable water is introduced to augment the lost water due to blowdown and evaporation. Working with the US Bureau of Reclamation’s Desalination and Water Purification Program, a Garver-led team conducted an 18-month pilot study evaluating a ZLD process train aimed at further protecting Colorado’s valuable water supplies, while possibly promoting a circular economy.
Speakers: Water and Energy Practice Leader Eric Dole, PE, PSAP and Yuliana Porras-Mendoza (USBR)
4-4:30 p.m.
The Best Asset Management Program Incorporates Energy Management Principles
For years, traditional asset management utilizes ASHRAE Level 1 audits where a visual assessment of a critical process components, such as pumps, blowers, filters, clarifiers, tanks, pipes etc. are performed. The engineer develops an inventory list and a risk register by coupling the field assessment data with the historical maintenance logs. This risk register is used to systematically evaluate risks, define their priority and potential impact of failure, and document mitigation strategies with their respective costs. But does this tell the entire story? For electro-mechanical equipment, such as pumps and blowers (and the processes that depend on them), the answer is no. This presentation will discuss how to integrate energy management principles, like energy intensity mapping, wire to water testing and wire to air testing to improve the likelihood of failure accuracy while integrating energy savings and demand side rebates to buy down the cost of replacement.

10:30-11 a.m.
Four Ways the City of Fort Worth is Preparing for Compliance with the Lead and Copper Rule Revisions
This presentation provides an overview of the Lead and Copper Rule Revisions (LCRR) and will focus primarily on the City of Fort Worth’s multi-faceted approach to preparing for compliance. The City’s strategy includes identifying and replacing lead service lines, developing public outreach strategies, implementing protective water quality standards, and budgeting for LCRR activities. Elements of the strategy can be applied by water systems of all sizes across the United States.
Speaker: Distribution System Water Quality Practice Leader Ashley Pifer, Ph.D., PE
2:30-3 p.m.
Treatment Considerations for HAB and T&O Control
This presentation provides an overview of common approaches for treatment of HABs, cyanotoxins and T&O compounds, and an update on latest technologies.
