UCT is pleased to welcome Jo Ann Macrina, Commissioner of the Department of Watershed Management for the City of Atlanta, as the speaker for our 2016 keynote session. Appointed by Mayor Kasim Reed in April 2011, Macrina is committed to providing quality drinking water; protecting and improving Atlanta’s water resources; complying with federal and state regulations; promoting teamwork and accountability; and, building partnerships throughout the city.

Macrina brings unique knowledge to UCT 2016 with over 25 years of experience in Water Resources, where she has served in both public and private sectors. She has managed departments, projects and programs with her work focused on total water management including stormwater, drinking water and wastewater.

Macrina holds a BS in Civil Engineering from the University of Texas and a MPA from the University of South Florida. She was appointed to the Stakeholder Advisory Board for Erosion and Sedimentation Control in Georgia by Governor Perdue, and has served on the board since 2004. She was also awarded Engineer of the Year in 2006 by the the American Society of Civil Engineers. Her professional affiliations also include the American Water Resources Association (AWRA) Georgia Chapter, Georgia Water and Pollution Control Association Board of Directors, and the Gwinnett-Fulton County Junior League.

UCT’s WaterWorks Conference Schedule

Wednesday, February 3

Room B403
Track Moderators:
Russell Ford, Corporate Business Development Mgr., Lockwood, Andrews & Newman
John Matthews, PhD, Program Manager, Pure Technologies

9 – 9:40 a.m.
Keynote Speaker: Atlanta Watershed Commissioner
Commissioner Jo Ann Macrina, PE, Atlanta Dept. of Watershed Management

9:40 – 9:55 a.m.
The Evolving Nature of America’s Water Issues, Technologies

10 – 10:25 a.m.
Live Pressure Main Condition Assessment Technologies
John Matthews, PhD, Program Manager, Pure Technologies
Jennifer Steffens, PE, Program Manager for CCMWA, Pure Technologies
Condition assessment tools for live pressurized mains are rapidly evolving. Advanced assessment methods provide in-depth analysis of internal and external pipeline conditions useful for specifying rehabilitation, repair, and/or replacement. This presentation examines the benefits and limitations of live pressure main inspection techniques.

10:30 – 10:55 a.m.
PCCP Transmission Main Inspection for Cobb County-Marietta Water Authority
Jennifer Steffens, PE, Sr. Project Manager, Pure Technologies
Cobb County-Marietta Water Authority (CCMWA) is the second largest drinking water supplier in Georgia, providing service to nearly 800,000 people through 12 wholesale customers. Since 2012, CCMWA has been proactively managing the PCCP within their inventory through a comprehensive condition assessment program. This presentation will discuss the various methods utilized by CCMWA to manage their PCCP inventory.

11 – 11:55 a.m.
Carbon Fiber Transmission Main Repairs: Getting it Right
Ian Lancaster, Area Manager-Eastern USA & Caribbean, Insituform Technologies
Over the past 10 years, rehabilitating large diameter water and wastewater pipelines (>36”) with carbon fiber reinforced polymers (CFRP) has increased dramatically. Though these types of laminates previously used successfully for decades on military and commercial aircraft, the application of CFRP in pipelines is a new frontier. This session will address recent findings from an ongoing five-year water main rehabilitation program with the Miami Dade Water & Sewer Department. Also shared will be changes made to specifications, quality control, testing, and inspection protocol to ensure that the engineering design life is exceeded.

Thursday, February 4

Room B403

8:30 – 8:55 a.m.
Tackling the Non-Revenue Water Issue
What is non-revenue water (NRW)? It is already produced water, yet is lost due to leaks, poor maintenance or theft before it reaches the consumer. Leak detection plays a key role in reducing non-revenue water as it allows utilities to optimize their system performance by surveying distribution mains (and other systems). Utilities can lower repair costs by finding and repairing leaks before a costly main breaks.

9 – 9:25 a.m.
A New Perspective and Process for Pressure Pipe Lining
George Bontus, PE, Director-Engineering, Aegion
Pressure pipe rehabilitation using lining methods has evolved over the past decade, with a variety of products entering the market. This presentation provides a description of the development of a new and innovative carbon fiber based lining system, including application of design standards and guidelines that address some of the existing ambiguities. The testing of material and physical properties during product development support the design case and the structural rating. A project case study illustrates some of the new processes and procedures involved in this structural pressure pipe lining system.

9:30 – 9:55 a.m.
Water Main Replacement in an Urban Environment
Jonathan Walker, Capital Linear Section Manager, Dept. of Watershed Mgt., City of Atlanta
The city of Atlanta, like most cities in the U.S., has an aging infrastructure. The water distribution system in some areas is more than 100-years old and requires a continual replacement program in order to meet the needs of the city’s growing constituency. This presentation will cover the following: How the city of Atlanta manages it water main replacement program from assessment to actual construction; Criteria for Water Main Replacement – there is no way to replace all water mains at once, so how do you decide which lines to replace and when; and Recent water main replacement projects – projects range from a few hundred feet to 20,000’ and from the small neighborhood to downtown Atlanta.

10 – 10:25 a.m.
Steel Slip Lining Rehabilitation of a 90” PCCP
Cole Kratochvil, Project Engineer, Kiewit Infrastructure West Co.
David Markert, Project Manager, Kiewit Infrastructure West Co.
The project included the rehabilitation of approximately 6,262 LF of 90” PCCP water main. The rehabilitation requires the use of 87” split-can and 84” solid-can steel slip lining that is inserted into the existing host pipe. The split can is expanded and welded longitudinally and around its circumference in a bell and spigot connection. The solid can eliminates the longitudinal weld. The annular space between the host and new liner pipe is grouted, and the new liner is cement mortar lined and cured to create a new pipe.

10:30 – 11:25 a.m.
KWA Lake Huron Water Supply Intake
J. Warren Green, PE, Director of Engineering, Lockwood, Andrews & Newnam
Jeremy Nakashima, PE, Senior Project Manager, Lockwood, Andrews & Newnam
Communities in Genesee County, MI, have been receiving their water supply from the Detroit Water and Sewer Department (DWSD) since the late 1960s. This supply was delivered through a single 72” diameter pipeline. A number of challenges were encountered during the design of a new system, including high groundwater conditions for the tunneling portion of the work; bury depths of over 50’, pipeline connections made in “wet” conditions, control of frazil ice, mitigation of aquatic life impacts, zebra mussel control and quality control of pipe installation. Discussion will include lessons learned in addressing these challenges.

11:25 – 11:55 a.m.
Pipe Bursting: Ideal Technique for Replacing AC Water Distribution Pipes
Alan Goodman, National Sales Manager, HammerHead Trenchless Equipment
This session will focus on a large-scale AC replacement project out of Georgia. This project was converted from open-cut construction to pipe bursting due to the congestion of utilities surrounding this AC water line.
