Consulting Firm’s Presentations to Highlight Water Management

Joe Mantua, a Black & Veatch Client Services Manager and American Water Works Association (AWWA) President, will preside over the AWWA’s 130th Annual Conference & Exposition (ACE11) to be held June 12-16 in Washington, D.C. The conference brings together thousands of water sector leaders to examine issues such as water quality, finance, and sustainability.

“This year’s conference theme is leadership, so it’s fitting that we will be meeting in Washington, D.C. – a place where decisions routinely impact the entire globe -- to bring together thousands of water sector leaders to examine the critical issues of our day,” Mantua said. “As the challenges of water quality, finance and sustainability grow, so does the need for strong leadership on these and many other water issues.”

At the conference, Black & Veatch will present 22 technical papers, including a behind-the-scenes look at the planning, permitting and development of a long-term water management strategy, presented on Thursday, June 16, by Pam Kenel. A Water Resources Global Practice & Technology Leader at Black & Veatch, Kenel will take a look at the long-term water management strategy that Loudoun Water is developing to meet the future needs of its customers in a reliable, environmentally conscious, and sustainable manner. To meet maximum day water use requirements in 2040, Loudoun County will require 90 million gallons per day of water supply.

The presentation will address the process to plan for and secure permits to construct a new Potomac River intake, pumping station, and water transmission and treatment facilities, in addition to the conversion of a rock quarry for raw water storage.

A desktop evaluation was conducted to identify the preferred program concept, and more detailed resource inventories were performed to quantify potential impacts to cultural and natural resources. Proactive installation of pipe sleeves under newly constructed roadways; use of pre-design evaluations to minimize impacts during construction; and collaboration with Loudoun County business partners to maximize the benefits associated with the project were combined to satisfy local, state, and federal needs in a responsive, transparent, and sustainable manner.

Other papers being presented by the global engineering, consulting, and construction company will touch on zero liquid discharge desalination, utility-wide strategic energy planning, and climate change adaptation strategies, to name a few.

ZLD Desalination of Brackish Water with an Innovative Form of Electrodialysis

In this June 15 presentation, Rick Bond, a Black & Veatch Water Technology Process Engineer, will discuss a new electrodialysis technology, referred to as electrodialysis metathesis (EDM), for zero liquid discharge (ZLD) desalination of brackish water. In Water Research Foundation Project #4163 Bond conducted research to evaluate the process using EDM with the goal of reducing costs and energy requirements for ZLD desalination. Characteristics of EDM create advantages with decreased fouling potential. In his presentation, Bond will discuss the EDM technology, pilot-scale test results, and evaluations of full-scale treatment costs and energy requirements for this ZLD method.

Optimizing Technology and Economics: Utility-Wide Strategic Energy Plan

This presentation by Stephen Tarallo, a Regional Business Lead for Sustainable Solutions at Black & Veatch, will describe the strategic energy planning process designed to deliver the Philadelphia Water Department a balanced portfolio of energy efficiency and renewable energy initiatives targeted at reducing energy consumption, greenhouse gas emissions, and energy costs. The presentation, scheduled for June 13, will discuss the evaluation of capital project initiatives with a focus on the economic evaluation using a cash flow modeling approach. The evaluation incorporates time-variable energy demands, price forecasts of delivered electric and natural gas, and capital cost projections.

Sustainable Water Resources Management for a Changing Climate: Comparison of International Best Practices

Demand for water has been on the rise as a result of population and development growth. At the same time, an increased occurrence of extreme weather arising from climate change reduces the reliability of water supplies from existing sources. Under the circumstances, water providers across the globe strive to identify sustainable, cost-effective and politically acceptable programs for managing their water resources. Comparisons of seven leading climate change adaptation strategies will be provided in this June 15 presentation by Les Lampe, a Black & Veatch Global Practice & Technology Leader.
