EPA’s WIFIA Program: A Powerful Option for Water and Wastewater Project Financing
Through the Water Infrastructure Finance and Innovation Act of 2014 (WIFIA), the US Environmental Protection Agency (EPA) offers substantial financial assistance for water, wastewater, and storm water projects. WIFIA’s unique financing terms and flexible application process make it a great option, but a lack of awareness has led Texas to fall behind in terms of WIFIA funding. Using the City of Pflugerville’s WIFIA experience as an example, this presentation will inform you about the program’s benefits and help you build a comprehensive funding strategy for your project.

Tuesday – September 19 at 6:00 pm

Tom spent 13 years developing and managing state financial assistance programs, including more than seven years at the Texas Water Development Board (TWDB) and six years working with the Texas Community Development Block Grant program (TxCDBG). He has direct experience administering and supervising a long list of infrastructure funding programs and played a key role in the development of recent additions such as the Flood Infrastructure Fund (FIF), Asset Management Program for Small Systems (AMPSS), and revamped Economically Distressed Areas Program (EDAP). As a Funding Specialist at STV, his goal is to help communities understand their public financial assistance options and pursue the ones that suit them best. Tom studied Philosophy at the University of Texas at El Paso.

Keep Austin Beautiful – Adopt a Creek
September 9th, 2023, 9 am-12 pm

Due to increased interest in creek clean-up events, CAC TAWWA and CTS WEAT have formally adopted a creek segment! As part of Keep Austin Beautiful, we adopted 0.41 miles of Tannehill Branch West within Bartholomew Park. Over the next two years, we will have a creek clean-up event once a quarter to pick up trash and maybe even clear out some invasive species and revegetate the creek area with native species. For each event, CAC TAWWA will provide trash bags, grabbers, gloves, bug spray, etc. – anything you’ll need.

Come join us to kick off this project on September 9th, 2023, 9 am-12 pm! We have dubbed ourselves the Bartholomew Brush Busters and we want YOU to help us bust some brush. We will meet in the parking lot of Bartholomew Municipal Pool. If you have any questions, please contact Hannah Leppla at

Membranes for Selective Ion Separations at the Water-Energy Nexus
Yale School of Engineering and Applied Sciences:
Dr. Menachem Elimelech

About the Speaker: Professor Elimelech received his B.S. and M.S. degrees from the Hebrew University of Jerusalem and his Ph.D. in Environmental Engineering from Johns Hopkins University in 1989. In 1998, he moved to Yale University to initiate their Environmental Engineering program. His research is in the general area of the water-energy nexus. Specifically, the research in his group involves: (i) membrane-based processes for energy-efficient desalination and wastewater reuse, (ii) advanced materials for next-generation environmental separation and water decontamination technologies, and (iii) environmental applications of nanomaterials. Professor Elimelech has received numerous awards for his research, including the Clarke Prize for excellence in water research in 2005, the Eni Award for Protection of the Environment in 2015; election to the National Academy of Engineering in 2006, and election to the Chinese, Australian, and Canadian Academies of Engineering in 2017, 2021, and 2022, respectively.

Abstract: Synthetic membranes are enabling components in key technologies at the water-energy nexus, including desalination, water purification, and energy conversion. Many applications at the water-energy nexus require ion selectivity, or separation of specific ionic species from similar species. Herein, we highlight how insights from nanofluidics and ion-selective biological channels establish the basis for a new class of membranes with ion-ion selectivity. We present a few examples demonstrating the paramount role of ion-membrane interactions in governing ion permeability and selectivity. First, we assess how ion–membrane binding energies affect the permeability of cations of similar size (copper, nickel, zinc, cobalt, and magnesium) through a multilayered polymer membrane. We observe that metals with higher binding energy to iminodiacetate groups of the polymer, which we determined via density functional theory calculations, selectively pass through the membrane in multi-salt solutions. Weaker binding species are precluded from partitioning into the polymer phase, which reduces their passage in proportion to their binding energy. Second, we report the ion permeability and selectivity of composite membranes comprising a selective thin film and a cation exchange membrane as the base layer. We characterize the separation performance of the composite membrane in electrodialysis showing that the polymer selective layer markedly increased the selectivity of the cation exchange membrane. We conclude with computational studies to further elucidate the roles of (i) pore mouth interactions versus intrapore interactions, (ii) spacing and arrangement of functional groups, and (iii) channel length in controlling ion-ion selectivity.
