ASCE’s Government Relations Team Advocates for Environment and Water Resources EWRI: Celebrating 20 Years EWRI Convenes Summits on Future EPANET and SWMM Development Opportunities and Challenges in Leveraging New Generation Telemetry, Software-Defined Networking and Cybersecurity In “Internet of Things (IoT)” For Environmental Sensing The Water and Water Resources Aging Infrastructure Chapter Spotlight: Pittsburgh & St. Louis
What role does EWRI play in the world beyond being a trusted professional organization delivering credible cutting‐ edge information? Some recent activities will help answer this question: the 8th World Water Forum in Brasília, Brazil, and the ASCE Annual Legislative Fly‐In in Washington, D.C., a member advocacy event. It was serendipity that the 8th World Water Forum, held from March 18 to 23, was in my home country and in the capital, where I lived as a child. From the perspective of someone who grew up in Brazil until age 13 and who visits the country annually for work or family visits, I saw how important it is for a U.S.‐based organization to be present in a major event in a developing country. Whether people like it or not, Americans are expected to be leaders around the world. Countries who struggle with implementing technologies and policies related to water expect our presence and expertise. While the U.S. and other developed countries can serve as examples of many water management practices that work well, it’s also important to send the message that we in the U.S. can always improve. At the panel Fostering New Cutures of Participation, a Brazilian asked me how developing countries can possibly emulate developed countries if developed countries already have everything figured out. I responded that the efforts for managing water that I see in developing countries are impressive and creative, and the people involved should be proud of their progress. There are opportunities for developing and developed countries to learn from one another; in developed countries, we don’t have it all figured out. The Forum, organized by the World Water Council based in Marseille, France, is not just a technical conference. This year’s theme, Sharing Water, encompassed all the different topics and World Water Council president Ben stakeholders present. I Braga (left) and EWRI member Dale Jacobson (right) at the 8th World participated in sessions ranging from justice, Water Forum in Brasília, Brazil. politics, financing, capacity building, sustainability, and industry.

PRESIDENT’S MESSAGE been in the WWC Board of Governors since 2012, represented by members Dale Jacobson and Daene McKinney. The professional conference within Forum was attended by 10,500 people; the political meeting received 12 heads of state and 60 ministers. Importantly, 109,000 children and the lay public attended the free‐of‐charge Citizen Village, an educational and interactive set of exhibits about water. In such an enormous event, I expected a chaos of ideas. The session for drafting the Forum’s Sustainability Declaration was well‐run, but I was skeptical of what would come of it. I was immensely pleased during the Closing Ceremony when moderators from all themes and regions reported on conclusions and routes for action. Some of the exact words from EWRI were used in the Sustainability Declaration read during the Ceremony. In essence, ideas from the forum can result in country‐wide policy changes and United Nations action. All of the final documents can be found online. All of them are a good read for those of us who focus on technical projects and want to know the greater context of our work. Closer to home, several EWRI members went to Washington, D.C., to meet with their members of Congress and their staff to ask for infrastructure funding. ASCE has held the Annual Legislative Fly‐In every March for almost 20 years. The event, combined with aggressive marketing of the Infrastructure Report Card, has kept infrastructure in the minds of legislators and the public. You can read more details about the event in the Government Relations section of this newsletter. Keeping track of legislation that affects environmental and water resources professionals, and acting to push for funding and best practices, is an important way to stay relevant in the profession. Those in our technical profession who are inclined towards the political process can represent the profession to our local, state, and federal legislators. There is no need to be an expert in the legislative process at the outset; one way to start learning is to become an ASCE Key Contact and send letters to your members of Congress when relevant legislation is being considered. Now, back to more technical matters. EWRI held the
EPANET and SWMM Summits on April 3‐5. EPANET and SWMM are software packages developed by the EPA to model water distribution piping and stormwater drainage systems, respectively. These software packages are heavily used by many EWRI members, and the need arose to create a community of developers to establish a shared vision for the future improvements and support of these tools. Thanks to Walter Grayman and Robert Traver who spearheaded the Summits and to EWRI members who contributed to the content. You can read more about this event in this newsletter. More related information will be shared with EWRI members at our annual Congress through a special session on EPANET and SWMM updates and a technical workshop titled Introduction to EPANET Water Distribution Modeling. Finally, I hope to see you at EWRI’s premier event, the World Environmental & Water Resources Congress in Minneapolis, June 3‐7. The program is full of technical sessions and workshops, as well as sessions for new professionals and students. Please, especially if you are a new attendee, stop me to say hi and tell me how EWRI can help your career. Cris Surbeck President, ASCE‐EWRI

ASCE’s Government Relations Team is Advocating for Environment and Water Resources Cris Surbeck This past March, 210 ASCE members, including several from EWRI, from 49 states, DC and Puerto Rico arrived on Capitol Hill to advocate for infrastructure and the civil engineering community through the ASCE Annual Legislative Fly‐In. Armed with their everyday civil engineering experiences, issues briefings from the ASCE Government Relations team, and insight from keynote speakers, Fly‐In attendees spent an afternoon advocating for aviation, water and water resources infrastructure, as well as urging members of Congress to draft a comprehensive infrastructure bill. Undersecretary for Transportation Policy Derek Kan spoke to the group with a discussion of the Trump Administration’s infrastructure plan and how the USDOT is progressing on a variety of issues including streamlining project decision making. Kan was followed by Reps. Garrett Graves (R‐LA‐5) and Elizabeth Esty (D‐CT‐5), who provided insights on what legislators hope to hear from constituents and how best to persuade their colleagues to support infrastructure funding.

This past January, ASCE submitted formal comments to the U.S. Department of the Interior’s Bureau of Safety and Environmental Enforcement’s (BSEE) proposed rescission of Obama‐era safety measures that were instituted after the 2010 Deepwater Horizon oil spill. BSEE is the federal agency that regulates offshore oil and gas drilling. During proposed rulemaking in 2010, ASCE submitted public comments in support of a provision that would require all operations to submit diagrams and drawings to BSEE for approval, and that those documents would have to be stamped by a registered Professional Engineer (P.E.). BSEE took ASCE’s comments into consideration and codified that provision in their final 2016 rule. ASCE’s most recent comments contain concerns with the proposed rule, which would change the aforementioned provision so that operators would only have to submit the most critical documents for approval by a P.E.–limiting the role that P.E.s play in mitigating the risks of offshore oil and gas facilities and in protecting public safety, welfare, and the environment. ASCE supports regulations that ensure the protection of public health, safety, and welfare and protection of the environment for all offshore development. This past January, Senators Boozman (R‐ARK), Booker (D‐NJ), Inhofe (R‐OK), and Feinstein (D‐CA) introduced the “Securing Required Funding for Water Infrastructure Now Act,” or the SRF WIN Act (S.2364), to help tackle our nation’s aging drinking water and wastewater systems. A House companion bill (H.R. 4902) was also introduced by Congressmen Katko (R‐NY) and Blumenauer (D-OR). This bill seeks to help states fund critically important drinking and wastewater infrastructure projects by using a combination of the most successful aspects of both the Water Infrastructure Finance and Innovation Act (WIFIA) and the State Revolving Funds (SRFs) and would build on the leveraging concept in WIFIA to provide a minimum of $50 billion in new funds for State Infrastructure Financing Authorities to utilize. ASCE members and Government Relations staff have been advocating on Capitol Hill in an effort to garner bipartisan co‐sponsorship of this bill; in fact, co‐sponsorship of this bill was one of our members’ “asks” at the March 2018 Annual Legislative Fly‐In. You can see our letters of support for the bill here and here. ASCE members are asked to contact their members of Congress to ask them to cosponsor the bill. www.asce.org/ewri • EWRI Currents • Volume 20, Number 2 • Spring 2018
This past February, the Trump Administration released an infrastructure proposal calling for $1.5 trillion in infrastructure investments, with $200 billion of direct federal spending over the course of 10 years. The federal investment is meant to spur investments from state and local governments and private investors. The proposal is divided into four main parts: funding and financing infrastructure improvements, additional provisions for infrastructure improvements, infrastructure permitting improvements, and workforce development. The plan does not identify a way to pay for the $200 billion in Federal investment, nor does it offer a plan to address the looming insolvency of the Highway Trust Fund (HTF). The Administration says that this plan will not add to the federal deficit, which means that funds must either come at the expense of other non‐mandatory federalprograms or the funding will be raised through a new source of revenue. A detailed summary of the plan can be found on the Save America’s Infrastructure blog, and you can read ASCE President Kristina Swallow’s, P.E., ENV SP, F.ASCE statement. ASCE members are asked to reach out to Members of Congress and urge them to craft legislation that will tackle our infrastructure deficit and build a stronger nation. This past February, ASCE sent Congressman Denny Heck (D‐WA) a letter in support of his bill, H.R.3906, the Innovative Stormwater Infrastructure Act. This bipartisan bill seeks to establish up to five nationwide centers of excellence, invest in community‐based stormwater control projects, and promote public‐private partnerships in the design and construction of innovative stormwater control infrastructure. ASCE’s 2017 Infrastructure Report Card gave the nation’s wastewater infrastructure, which includes stormwater infrastructure, a grade of “D+,” and the U.S. Environmental Protection Agency (EPA) estimates that $271 billion is needed for wastewater infrastructure over the next 25 years. As advocates of innovative and resilient infrastructure, ASCE supports this bill’s efforts to promote the use of green stormwater infrastructure system solutions. This past March, ASCE sent letters to the House and Senate Committees on Appropriations with our Fiscal Year 2018 and Fiscal Year 2019 funding requests for how we’d like to see Congress spend the recently passed budget deal’s $20 billion pot of federal funds for infrastructure investments. The letters urge Congress to appropriate those additional funds to existing federal infrastructure programs that have already proven to be successful, including the National Dam Safety Program, the National Levee Safety Initiative, the High Hazard Potential Dam Rehabilitation Program, and the State Revolving Funds, among others. ASCE reiterated that strategic, robust, and sustained investments, through long‐term, reliable federal funding, as well as through the utilization of alternative financing mechanisms, must be made quickly if we hope to close the nation’s growing funding gap and restore America’s world‐class infrastructure. Shortly after ASCE’s letter was sent, Congress passed a $1.3 trillion omnibus spending package to fund the government through the end of Fiscal Year 2018,which included additional funding for many infrastructure programs. A detailed summary of the omnibus bill can be found on the Save America’s Infrastructure blog. This past March, ASCE released a letter of support for H.R. 2943, the Outdoor Recreation Legacy Partnership Grant Program Act, a bipartisan bill that creates a dedicated source of funding of up to $25 million to expand outdoor recreation opportunities in urban communities and to promote the development of public‐private partnerships for such projects. In addition to acting as strong economic drivers, urban parks create dual‐use spaces for both recreation and green infrastructure stormwater management such as rain gardens. Using the natural environment to manage stormwater also provides co‐benefits such as aesthetic value to communities, improved water quality, and cost competitiveness compared to gray forms of infrastructure. ASCE’s 2017 Infrastructure Report Card gave our nation’s public parks a grade of “D+.” ASCE supports this bill as a way to help raise that grade. This past March, ASCE submitted formal comments to the Federal Emergency Management Agency’s Draft National Mitigation Investment Strategy, a document which is intended to “empower governments at all levels, as well as communities, individuals, the private sector, and nongovernmental organizations, by encouraging new ideas that result in innovative actions to reduce the risk from all hazards.” ASCE’s comments were informed by the Infrastructure Resilience Division and the Task Committee on Flood Safety Policies and Practices’ 2014 report entitled “Flood Risk Management: Call for a National Strategy.” 5
This past March, ASCE and seven drinking water and wastewater organizations sent a letter to the House and Senate Committees on Appropriations Subcommittees on Interior & Environment urging them to make robust federal investments in water infrastructure in Fiscal Year 2019. The letter specifically asks the Committees to double the funding for the Clean Water and Drinking Water State Revolving Funds; fully fund the Water Infrastructure Finance & Innovation Act (WIFIA) at its authorized FY19 level; fund EPA’s geographic watershed programs and categorical grant programs, the latter of which helps address communities’ nonpoint source pollution issues and implement stormwater management, at FY17 levels or higher; fund EPA’s Office Water’s Water Security Division at current levels; and fund the extramural research programs and the technology development, data collection, and monitoring programs at the Environmental Protection Agency (EPA), the U.S. Department of Energy (DOE), and the U.S. Geological Survey (USGS). ASCE was pleased that the FY18 omnibus included an additional $300 million for each of the State Revolving Fund programs. As part of a larger coalition led by the Pew Charitable Trusts, ASCE released a letter in March 2018 in support of S. 1507, the State Flood Mitigation Revolving Fund Act. This bipartisan bill is modeled after the successful Clean Water and Drinking Water State Revolving Funds and seeks to create a new state revolving fund program to provide low‐interest loans to states for flood mitigation projects such as elevations and flood‐proofing of public buildings, businesses, and residences; improvements to stormwater management; assistance to local residents who wish to move out of harm’s way; or converting frequently flooded areas into open space amenities. This April, Congressmen John Garamendi (D‐CA) and Bruce Westerman (R‐AR) submitted a letter to the House Committee on Transportation & Infrastructure asking that they reauthorize the National Levee Safety Initiative (NLSI) in the Water Resources Development Act (WRDA) of 2018. ASCE advocated to get this program authorized in the Water Resources Reform & Development Act (WRRDA) of 2014 and has been engaging Members of Congress to encourage it to be fully funded in FY19. The prior month, the same two Members of Congress led a bipartisan letter with the support of 24 Members of Congress to the House Appropriations Subcommittee on Energy & Water Development asking that the NLSI be fully funded in FY19 at its authorized amount of $79 million. Since its authorization, the program has only received between $5 ‐ $10 million per year. The NLSI creates levee safety guidelines, a national levee inventory, a levee rehabilitation and repair program, provides assistance to states for establishing participating safety programs, and promotes community education and awareness about levees. ASCE’s 2017 Infrastructure Report Card gave our nation’s levees a grade of “D” and recommended fully funding the NLSI as a way to raise the grade. House Ways & Means Committee Members Tom Rice (R‐SC-7) and Earl Blumenauer (D‐OR-3) plan to send a letter to Speaker Ryan and Minority Leader Pelosi urging congressional action on a significant, long‐term infrastructure bill. The Congressmen are urging leadership to steer the House towards a comprehensive bill that addresses the infrastructure needs of all communities. ASCE members are asked to contact their Representative in the House before May 4 to urge them to sign on to this letter.

EWRI: Celebrating 20 Years Jerry Rogers The new EWRI Task Committee to help plan the EWRI 20th Anniversary (1999‐2019) in Pittsburgh May 19‐23, 2019 is summarizing some EWRI achievements. Task Committee members Conrad Keyes, Jr., Jay Fredrich, Michael Ports, Larry Magura, and Jerry Rogers (Chair) have been joined by Werner Loehlein ‐ ASCE/EWRI Pittsburgh during conference calls and the 6:30‐10pm Mon. June 4, 2018 meeting in Minneapolis in Lakeshore C. The summary below is the first of a series of EWRI achievements over its pending 20th year. In his articles, Steve Starrett cites the EWRI research compiled by Brian Parsons and EWRI staff during 2016. Since the establishment in 1999, EWRI has partnered with over 55 professional societies, universities, companies, and international entities to conduct studies, develop solutions, publish results, and host conferences. Among these collaborations, the involvement with the World Water Council (WWC) is noteworthy. Established in 1996, WWC promotes awareness, builds political commitment, and triggers action on critical water issues at all decision‐making levels. There are 342 organizations, governments, and enterprises from 42 countries involved. Another influential collaboration has been with the International Upper Great Lakes Study initiated by the International Joint Commission (IJC). EWRI has continued to empower its members through education and networking opportunities. Frequent conferences facilitate both of these. Through 2017, EWRI has hosted over 50 conferences, with at least 12 being international. In addition to the usual Journal articles, manual of professional practices, and detailed standards; the online workshops and classes are also available to expand our membership’s knowledge. Over 130 courses are offered with a focus on practical application and the latest developments. The newest movement to empower members is the launch of EWRI Collaborate. Established in 2014, Collaborate is an online platform that facilitates open forum discussion, committee collaboration, exchange of ideas, and networking; as well as the location of numerous materials developed by the various task committees and committees of the Institute.

EWRI CONVENES SUMMITS ON FUTURE EPANET AND SWMM DEVELOPMENT Walter Grayman and Robert Traver In early April, EWRI convened and hosted two 1-1/2 day Summits, one with the mission of framing a shared vision for the future development of EPANET and the other on the future development of EPA SWMM. Both workshops were convened in association with the new National Center for Infrastructure Modeling and Management (NCIMM), EPA and the broad user and software development community. For each workshop, 35 invitees representing the user, software developer, research, and regulatory community gathered at ASCE headquarters in Reston, VA for a series of plenary presentations and facilitated breakout groups. EPANET was developed 25 years ago and has become the standard public domain program for water distribution system analysis. EPANET is used widely around the world as both a research and application tool and the hydraulic and water quality engines are the basis for many commercial software packages. The assembled group in Reston was charged with three basic questions: 1. What is the appropriate structure and style for future EPANET development? 2. What additional functionality is needed in EPANET and other water distribution system modeling software? 3. How can the various members of the EPANET community work together to best move EPANET forward in the future?
Figure 1: EPANET Summit Attendees
In response to the charge, the following recommendations were made: 1. A phased program for future EPANET modifications was outlined including: near term modifications to the engine to address some identified deficiencies; development of EPANET 3 using an object–oriented structure; and the possibility of a complete longterm restructuring of EPANET in the future. Options for the development of alternative GIS-enabled graphical user interfaces (GUIs) were discussed. 2. Additional functionality for EPANET and other water distribution system models were identified in the areas of: user experience, development needs, hydraulics, and water quality. 44 specific areas of functionality were enumerated. 3. There was general agreement surrounding the continued development of EPANET as an open-source project, with strong community contributions and based upon a permissive license. While the general agreement is a good step forward, more specific details need to be addressed within the broader framework. Continued discussion among the represented groups will further shape the overall development to ensure that the diverse EPANET community can work together effectively to further the advancement of EPANET. EPA’s Storm Water Management Model (SWMM) is the preeminent tool for planning, analysis, and design of urban hydrologic and sanitary systems. Initiated in the late 1960s, it simulates generation, conveyance, and mitigation of urban runoff and non-point source pollutants in sanitary, combined,
www.asce.org/ewri • EWRI Currents • Volume 20, Number 2 • Spring 2018
and stormwater drainage systems. It is an excellent example of technical community accomplishment through partnership of stakeholders from all avenues of professional practice. SWMM has been built over five decades with participation from regulatory, academic, consulting, owner/ operators, and software vendors, with long-term interest and support from EPA. The SWMM session started with presentations reviewing the development history, and then moving to the present. Of interest was a presentation by NCIMM focused on current research at UT/Austin which is expected to lead to a faster and more flexible alternative to the existing hydraulic solver in SWMM. Following these presentations, participants were assigned the following questions: 1. What changes in SWMM can be made now to increase its value to the engineering design and regulatory community? 2. What future vision of SWMM can be imagined? What applied and fundamental research and supporting data and knowledge are needed to meet this vision? 3. How can the EWRI community help sustain and develop SWMM? 4. Final thoughts and next steps. The following recommendations were made: 1. Participants reviewed and ranked proposed changes to SWMM and added many more ideas for future upgrades. Ideas included adding design storm and NRCS unit hydrographs, GIS interfaces, and data tables to allow for easier data updates. 2. Suggestions for future versions of SWMM included an added approach for modeling water quality, changes to LID modules, and modeling of sediment from
streambank erosion for water quality. 3. The connection with EWRI was clearly established. Ideas discussed included mini courses supported by NCIMM at future EWRI conferences, SWMM-focused task committees, and future special collection in EWRI journals. There was discussion of the benefits of collaboration between NCIMM and EWRI, and it was concluded that this should be explored further at the upcoming Congress. 4. An early observation was that most practicing engineers are not aware of several projects that embed SWMM in different computing environments, such as Python, MATLAB, R, and QGIS. It is recognized that these capabilities should be communicated to the EWRI membership. Additional discussions included how the future add-ons will become a future architectural feature for SWMM that would allow developers to extend SWMM’s capabilities without having to change the core code. A special session on the results of the summits is planned for EWRI’s World Water and Environmental Congress in Minneapolis on Sunday, June 3 from 5:00 to 6:30 PM. A similar session, demonstration and workshop is planned for the First International WDSA/CCWI Joint Conference on July 23-25, 2018 in Kingston, Ontario, Canada (EWRI is a co-sponsor of that conference). Additionally, committees have been formed within EWRI (EPANET Visioning Task Committee and the Stormwater Modeling Visioning Committee) to continue the mission of the summits. The groups plan to prepare white papers on the future of EPANET and SWMM. This article was prepared by Walter Grayman and Robert Traver, co-chairs of the EPANET/SWMM summits with contributions from the summit organizing committees.

Opportunities and Challenges in Leveraging New Generation Telemetry, Software-defined Networking and Cybersecurity in "Internet of Things (IoT)" for Environmental Sensing Dr. Sudhir Kshirsagar, P.E. Global Quality Corp. and HydroTrek.com
INTERNET OF THINGS (IOT) FOR ENVIRONMENTAL SENSING The advances in the Internet of Things (IoT) technologies over the past few years have been fueled by the incorporation of these technologies into consumer devices such as health trackers, smart watches and smart home gadgets. A single new generation chip is now capable of communicating with the attached sensors, storing the data into local storage and transmitting the information via a generation of low power protocols such as Bluetooth Low Energy (BLE) or Long Range Wide Area Network (LoRaWAN). Some of these protocols also can be configured to provide mesh or star networks that can cover several miles of rugged terrain. Typically, the data feeds from the IoT sensor nodes are merged into one or more gateways that are connected to a cloud-based back-end. For example, the data captured by a smartphone is first received by a computing unit on the nearest cell tower, and then forwarded to the service provider’s private cloud for further processing. The consumer centric IoT advances are now starting to spill over into the industrial sector with a strong emergence of Industrial IoT (IIoT) devices that have legacy industrial protocols and new emerging IoT protocols. The cybersecurity aspects of IoT get a stronger focus in such situations, and advanced security software and hardware is typically incorporated into the overall solution. If we think of Environmental IoT (EIoT) as a type of IIoT subsector, then it becomes possible to compare and contrast the growth and emergence of EIoT compared to other subsectors such as automotive. It is clear that the growth of EIoT is driven by the limited demand at this point, and we will examine some of the reasons behind the slow growth in a later section. It is also possible to think about EIoT as subset of consumer IoT where the demand is driven by the incorporation of smart environmental sensors into homes and farms. That is clearly a much larger market compared to the industrial market. For example, internet-enabled soil moisture sensors and rain gages can be sold in this market if the value proposition can be clearly established. However, the barriers to a large-scale adoption of EIoT in the consumer market are quite significant, and consumer education can play a key role in removing some of the obstacles. www.asce.org/ewri • EWRI Currents • Volume 20, Number 2 • Spring 2018
ENVIRONMENTAL SENSING A large number of sensors with a variety of price ranges that mainly address the needs of the industrial sector have existed for a long time, and they leverage a variety of physical and chemical methods in the measurement process. One of the biggest challenges in measuring anything in the environment is that the “Environment” is harsh on the sensors, and the sensors have to be protected from the environment. So the space reduction advantages gained by shrinking the size of the chip that implements a sensor are quickly wiped out by the need to provide perhaps a robust “windshield wiper” system that keeps the optics clear. This scenario is clearly quite different compared to smart-phone scenario where a designer is including an accelerometer into electronics of the phone. A related issue is that the installation of an environmental sensor is also labor-intensive today, and the reliability of the installed device becomes a key purchasing factor. Another important factor is that the public-facing environmental sensors are prone to vandalism, (everyone is tempted to snap off a rubber antenna that sticks out), and vandal-resistant designs have to be carefully constructed. CONNECTING EVERYTHING TO EVERYTHING, THE INTERCONNECTION MATRIX It is also interesting to think about a broad definition of the “Environment” and then look at the problem of connecting the nodes in that network. If our environment is defined as “everything that surrounds us,” then the other individuals, our communities and countries, and the infrastructure that we are immersed in including driverless cars and autonomous drones, become core components of such a massive environment. We propose that the complexity of that magnitude can be managed and visualized better through the use of a population abstraction used in the programming of field programmable gate arrays (FPGA’s), namely, the interconnection matrix. So instead of the thinking of the typical stovepipe notion of connectivity where data flows from sensors to concentrators/gateways to databases that are analyzed and downloaded for human consumption, one can think about how one sensor can be connected to another sensor or to a human as a wearable device, or how an individual can be connected to the rest of the community through a “social network.” The information flows are still executed through the transfer of bits and bytes for the most part, but all our cognitive senses are leveraged and loaded to the fullest extent as interfaces in the information flow. The broad concept of an interconnection matrix also enables us to think about connections that were previously ignored, and emphasizes the importance of assigning a weight to every cell in the matrix where a cell value reflects the importance of connecting a node i to another node j. A broader vision of the environment also serves to frame the context, the rules and policies, that balance the environmental benefits against the economic costs. A broader dissemination of environmental information through a powerful interconnection matrix has the potential of achieving the ‘smart connected communities’ vision if the risks that threaten the existence of that data fabric are carefully addressed. The rest of this article will focus on some of the challenges involved in the implementation of a subset of the interconnection matrix for environmental sensing. THE NEW GENERATION OF LOW COST SENSORS, MICROPROCESSORS AND TELEMETRY A common reaction to these sensors can be labeled as an ‘inverse sticker shock’ where the first question tends to be, “if I can buy a temperature, humidity and pressure sensor for the same price as that of a cup of coffee, is that sensor any good?” Interestingly, the answer usually would be that not only is the new sensor quite good but it is also a lot better than what our grandfathers had access to. These sensors are usually surrounded by intricate electronics that allow them to talk to a microprocessor. Fortunately for us, several high quality manufacturers provide ‘breakout boards’ with affordable electronics that makes it feasible to explore the properties of these sensors in a garage-based operation. The next piece in the connectivity tends to be the microcontroller that talks to the breakout board using industry standard and legacy protocols. A variety of methods of programming these microcontrollers have emerged but two revolutionary efforts have been the Arduino and the Raspberry Pi platforms. The Arduino platform that consists of an interactive development environment (IDE) and a plethora of low cost microprocessing boards made it easy to write programs that could be downloaded and executed on the microprocessors in literally a few minutes. The platform used the same robust compilation and linking methods but the complexity was all hidden away from the user. The Raspberry Pi offered 13
a solid computing platform, initially based on Linux, for the same cost as an average dinner, to a more intermediate level audience who knew how to get around in Linux. The key contribution of the Raspberry Pi was to offer both a solid operating system coupled with the ability to connect the “breakout boards of sensors” to the hardware through a set of general purpose input output (GPIO) pins. The massive adoption of the Arduino (Figure 1) and the Raspberry Pi in both academic and hobbyist circles led to the creation of a vast amount of open source software that could be leveraged to connect the sensors to the microprocessors.
Figure 1. Wiring an Arduino Board
The microprocessors have also evolved to offer both computing and communication on the same chip. In other words, the usual painstaking process of coupling a computing unit with a separate radio chip is now addressed directly in the new hardware that costs the same as an older computing unit from just a couple of years ago. The second advantage is that these combined units are offered only after going through the “communications” certification process, and the overall cost of offering telemetry units with these new chips is lowered substantially. Two good examples of such combined units exist in the Bluetooth Low Energy (BLE) and the LoRaWAN space where the microprocessors offer ARM Cortex M4 level computing power. That computing power is essential for juggling the tasks of talking to multiple sensors while transmitting the data without missing a beat. In other words, these processors support multi-threaded firmware for increased reliability and security. The telemetry supported by these processors is also quite well suited for most of the environmental sensing where only a few bytes of information are transferred every hour or so. There is a wide-spread adoption of this new telemetry in Europe, and the US market has been slow to respond. Similar to how the cell phone data standards evolved in the USA, IoT sensor data transfer standards are going through a similar process. The problem is further complicated by the fact the majority of the environmental sensing telemetry uses the 3G standard, and support for 3G is being www.asce.org/ewri • EWRI Currents • Volume 20, Number 2 • Spring 2018
phased out by the carriers. Another interesting twist to the telemetry space comes from the fact that it is possible to own a private outdoor gateway that can serve hundreds of nodes for a few thousand dollars. So these private gateways provide an interesting alternative to public gateways that are being offered by a new set of carrier companies. WHY IS SOFTWARE DEFINED NETWORKING (SDN) IMPORTANT IN ENVIRONMENTAL SENSING Going back to the concept of the interconnection matrix that was discussed earlier, it is somewhat obvious that a hard-wired set of interconnections will not offer the resilience and sustainability that is required in a large scale environmental sensing setting where millions of sensors interact with thousands of private and public gateways. The vision of millions of sensors transmitting data is not too far-fetched for even a community with a few hundred thousand residents. The ability to control and reroute traffic through the network through SDN is extremely important for such a scenario. The implementation of the SDN features are usually accomplished through one or more orchestrators running in the cloud that access the gateways in a cyber-secure manner through the use of IoT client-based information flow control software running on those gateways. One emerging vendor in this space leverages the Node-RED, an information flow management tool developed originally by IBM Research, to provide cyber-secure functionality for orchestrating infrastructure and network connectivity as a service. The core issues related to the provisioning and management of millions of sensor nodes provide some interesting implementation challenges when those problems are examined in the context of interoperability with the new generation telemetry carrier networks. The problem of moving a smartphone from one carrier network to another is not trivial but people have managed to deal with the nuances over time, and the portability of the SIM cards has been a key factor making that problem manageable. Unfortunately, the SIM card type of functionality is built into these new generation micro-processors/radio combination units, and the provision of a sensor node into a new carrier network will typically involve a firmware update that may have to be performed in harsh environmental conditions and not in the comfort of our homes. New research and industry initiatives promise address this area that would be critical to the success of large scale environmental sensing. WHAT ABOUT CYBER-SECURITY? Whether we like it or not, large scale environmental sensing has been and will be using the cloud-based platforms as the destination, and the data will be transferred through a combination of public and private protocols. Typically, the information flow from the gateways to the cloud will be over the public internet whereas the data exchange between the gateways and the sensor nodes will be through light-weight and in some cases proprietary protocols. So the implementation of a cybersecure environmental sensing platform can’t be achieved simply through the addition of hardware chips into the end nodes, and will require a system-wide approach that brings together the best-of-breed technologies to each of the network links. CONCLUSIONS Environmental sensing will benefit from the emergence of new technologies in the IoT spectrum but the challenges to the adoption of these technologies are significant. A broad examination of these challenges and the sharing of findings from those studies in a collaborative manner may be essential for a rapid uptake of these technologies into mainstream environmental monitoring projects.

The Water and Water Resources Aging Infrastructure Christopher H. Chiu, Monica Palomo, Lauren Redfern, Claudia Gunsch As it does every year, the American Society of Civil Engineers (ASCE) released the 2017 Report card for America’s Infrastructure. The report card depicts the overall infrastructure condition and performance, and once again a cumulative infrastructure GPA of D+ was assigned. This grade reflects the US infrastructure’s physical condition and its need for improvement. Aging infrastructure is posing a serious threat to US’s competitive edge in the global economy and to the public’s safety. The GPA of all the different infrastructure categories vary from D+ to B, while the categories related to water and water resources infrastructure ranged from D to D+. This paper provides a general overview of the situation experienced in the water and water resources infrastructure across the US. Water is a commodity that is taken for granted and that requires high quality to ensure health and safety of society. According to US EPA, the domestic water use per person varies from 75 to 200 gallons of water daily. About 70 percent of the water is used for indoor activities (add source to the list below). In addition, water has an important role in commercial, agricultural, and industrial use. According to USDA, nationwide up to 80 percent of U.S freshwater is used for irrigation, while up to 45 percent of it is used for generating electricity (source: USDA and USGS) The majority of the water infrastructure Americans depend on daily were put in service more than 50 years ago during the rapid economic growth and demographic change after World War II. Thus, millions of miles of water pipes that deliver potable water to American households and businesses are reaching or have reached the end of their service life. Aging water infrastructure leads to malfunctions and failures that may lead to disruption of potable water services that could affect human health. The majority of the aging water infrastructure experiences water leakage or pipe breakage. Water that has been treated and then leaks from the pipe networks causes direct financial losses. Thus, the reconstruction and maintenance of these pipe networks and facilities has risen to the top of the priority list Figure 2. Dam in Puddingstone Reservoir of some public agencies. According to the US Government Ac(San Dimas, California) countability Office, maintenance and expansion of service to fulfill society’s potable water demand for the next 25 years is estimated to cost $1 trillion. Of these costs, 65 % is needed to improve transmission and distribution, 20% for treatment, 10% for storage, and 5% for source protection and control. In the US, there are about 156,000 public water systems that each serve at least 25 people per day. There are more than 52,000 of these community water systems that serve about 286 million US households and 21,400 non-community water systems such as schools, factories, office buildings, and hospitals. (source: US EPA). Water Resources Pipeline networks includes the storage facilities across the communities. Storage is crucial to the water infrastructure to reliably supply water (with enough pressure and quantity) to the public at all times. Sufficient drinking water storage provides adequate supply during period of high demand. In addition, storage provides minimum pressure for the system which prevents contaminants from intruding into the distribution lines in the event of any leak or break.

estimated $39.5 billion will be needed over the next 20 years to rehabilitate or cover water storage tanks. Water Treatment Quality of the water source is critical to determine the treatment infrastructure needed to produce potable water. The challenges of existing water treatment infrastructure include the improvement, expansion, and/or rehabilitation of systems to meet drinking water standards with variable source water quality. Newer treatment systems are challenged with meeting standards and achieving high removals of salt or emerging contaminants, achieving smaller footprints, and reducing use of energy. (source: US EPA). In the last 20 years, there were reported incidents where the change in the quality of the water sources has negatively affected water utility facilities and the production of potable water. Treatment technologies are implemented to remove or prevent formation of harmful chemicals and to inactivate pathogenic organisms. Treatment processes range from simple direct filtration and disinfection with ultraviolet or chlorination to conventional treatment process (coagulation, sedimentation, filtration, and disinfection) or advanced treatment (advanced oxidation, ion exchange, and micro- and nano-filtration, among others). One of the biggest challenges faced by engineers and public utilities is the implementation of a system that can adapt the treatment processes to the variability of the incoming water source to achieve drinking water standards. Infrastructure Management Challenges Source water protection has become a critical task to prevent performance problems in the treatment facilities. Source water improvement can include obtaining higher quality raw water from newer surface water bodies or newer wells. However, with the limited amount of freshwater and its high demand, this is no longer a sustainable solution. Across the US, source protection has become the most important factor to obtain the highest possible quality at the water source, ensure robustness of the treatment works, and minimize the potential of chemical or pathogenic contamination (source: US EPA). The challenges that are currently being faced with the water and water resources infrastructure are not easy to overcome but they are solvable via strategic planning, continuous investment, and serious commitment of the public authorities and the community. The next article in this series will explore the details of several failures of the water and water resources infrastructure, and it will present the actions taken toward infrastructure improvement.

Chapter Spotlight EWRI Hosts Seminar on Chloride Impacts on Urban Land and Waterways Christina Urbanczyk

On February 26, 2018, the Environmental Water Resource Institute (EWRI) Chapter of ASCE‐Pittsburgh hosted a morning seminar on the Impacts of Chlorides on Urban Land and Waterways. The event was hosted at the Engineers Western Society of Pennsylvania in downtown Pittsburgh, PA in partnership with 3 Rivers Wet Weather, Three Rivers Quest, 3 Rivers Proud, Allegheny County Conservation District, American Public Works Association, Allegheny Watershed Alliance, Jacobs Creek Watershed Association, Nine Mile Run Watershed Association, Pittsburgh Water and Sewer Authority, Saw Mill Run Watershed Association, Southwestern Pennsylvania Commission Water Resource Center, and Westmoreland Conservation District.
The morning seminar was a series of presentations discussing the impacts of the elevated use of roadway salts in cold weather climate watersheds on surrounding land and waterways, and included perspectives on local, regional and national levels. Presentations and follow‐up discussions focused on quantifying salt loading and impacts over time as well as how to reduce loading by improving winter best management practice (BMP) maintenance. The seminar began with a presentation by Robert Hirsh, a research hydrologist with the US Geological Survey, Washington DC Office. Hirsh’s data from the past few decades indicates that an increase in chloride concentration in streams has outpaced urban growth. His data also demonstrates an increase in chloride concentration in groundwater and lakes. Hirsh further emphasized the need for continuous stream flow data to monitor chloride loading in conjunction with chloride concentration. The second presentation was delivered by Brady Porter of Duquesne University and 3 Rivers QUEST. Porter provided an overview on the seasonal chloride concentrations in the Allegheny, Monongahela and Ohio Rivers. Porter’s group is involved in the periodic sampling of numerous surface water locations along these rivers, as well as continuous monitoring with YSI probes. The impact of chloride toxicity in urbanizing watersheds was discussed on a regional level by James Houle of the University of New Hampshire. Houle discussed data collected from his research group on the performance of various BMPs on reducing chloride loading from salt applications. Because parking lots are a major source of chloride loading, Houle’s research primarily focused on salting of parking lots and the resulting friction resistance of various lot surfaces. Houle’s presentation indicated that salt reduction may be possible with no loss in surface skid resistance using alternative mechanical methods of application.

While a majority of the presentations focused on the impacts of chloride, Dan Bain from the University of Pittsburgh provided a different perspective by focusing on sodium impacts. Bain’s presentation highlighted that roadway salt applications cause legacy contamination, because both sodium and chloride alter metal mobility in soils. This discussion on the alteration of soil and water chemistry due to salt provided insight into the long� term effects of the roadway salt applications on the environment. The presentations at the seminar introduced a wide range of data and recommendations for further research from the local, regional and national level on the impacts of roadway salts. Erin Kepple Adams from the Southwestern PA Commission concluded the seminar with a discussion on the importance of improving winter BMP management with training and workshops, which may decrease salt use for deicing of roadways. Adams also provided seminar attendees with a useful resource guide on winter maintenance BMPs.

St. Louis Chapter Annual Symposium: A Partnership between the Local Chapter and the Technical Councils Focusing on Green Stormwater Infrastructure Shirley Clark Figure 1: Local and National Members of EWRI
On March 23, 2018, the St. Louis EWRI Chapter held their annual symposium at the Engineering Center in St. Louis. Partnered with EWRI St. Louis Chapter, the Technical Councils were honored to support 73 fellow engineers in their continuing education in stormwater and green infrastructure. Technical Councils representatives, Shirley Clark, and the current EWRI Vice‐President Scott Struck delivered opening remarks along with the Chapter’s past president Elise Ibendahl. A wide range of topics, were discussed from both local and national perspectives: • Metropolitan St. Louis Sewer District’s (MSD) new online plan review system by John Grimm • Case studies on the use of green infrastructure (GI) for reduction of combined sewer overflows both here in St. Louis and nationally by David Sample (Virginia Tech University), Jianpeng (Jim) Zhou (Southern Illinois University at Edwardsville) and Susan McCrary (MSD) • GIS for water infrastructure by Laura Miwirigi Rightler and Jeremy Linley (Civil Design, Inc.) • Retrofitting detention ponds for improved water quality benefits by Steve Klein (Barr Engineering) • LID/GI module in SWMM/PCSWMM by Azadeh Akhavan Bloorchian (Stantec, Inc.) • A national effort to collect data on GI maintenance costs by Holly Piza (Urban Drainage and Flood Control District, Denver, CO), and • A case study of GI operation & maintenance in Lancaster, PA by Ruth Ayn Hocker (City of Lancaster, PA). The organizing committee for the St. Louis Chapter 2018 Symposium consisted of Jiaman Xu, Azadeh Akhavan Bloorchian, Amanda Cox, Phillip Blonn, Melissa Marks, Robert Holmes, Elise Ibendahl, and Enos Inniss. This partnership builds off successful workshops in Austin, TX, and Seattle, WA where the program was developed to address issues of local interest and EWRI supplied 2 – 3 technical experts to supplement the local program on these issues. It is part of EWRI’s strategic plan to improve connections with the local chapters and also as part of EWRI’s Stormwater Strategy. Dr. Sample presented the work of the Low Impact Development in Combined Sewers Task Committee, while Ms. Piza presented the results of the Comprehensive Costs in Green Infrastructure Task Committee. Ms. Hocker chairs the Municipal Water Infrastructure Council.
