Wikipedia defines social responsibility as an ethical framework and suggests an entity, be it an organization or individual, has an obligation to act for the benefit of society at large. Those of us working in the water industry live that creed everyday – we do our jobs for the benefit of society at large; to keep us all from getting sick and protecting our surrounding environment from harm. But every individual, not just us, can be and dare I say, are empowered to be water stewards. The general public just doesn't know it. Through effective communication, utilities can build the partnership necessary to grow water literacy, improve working relationships for a better community, and foster trust in our expertise. Today, you will hear several case studies of communication strategies used from Kansas City, Japan, New Orleans, Atlanta, and San Francisco. You will be able to read in the conference proceedings what two utilities in Oregon did using opinion driven research to develop strategic messaging to gain support for increase in water rates and approval of bonds to support major water initiatives from author Clark Worth with Barney and Worth Inc in Portland Oregon.

The survey covered many topics specific to odors including management strategies, characteristics of the agency, staffing, treatment, maintenance, design and construction, compliance, good-neighbor strategies, and future needs/gaps in the field. Nearly 100 agencies participated across three countries and responded to up to 347 questions. Data from the survey will be presented in three broad categories:

1. Types of Odor Control Technologies Utilized 2. Maintenance, Operations, and Capital Investment of Odor Treatment Systems as a function

of Collection System and Plant Size 3. Odor Management: Organizational Resources, Regulatory Compliance, and Community

Engagement

Following each of the three presentations will be interaction among attendees to discuss how their experience compares to the survey findings. Going forward the committee plans to redeploy a survey every two to three years, and adjust depending on the needs. This half session will allow for dialog to inform the direction of a future survey.

325 Utility Leadership in Action: Becoming the Employer of the Future

Track: Effective Utility Management; Future Issues

Focus Area: Public Officials; Sustainability and Climate Change; Utility Management, Leadership, and EMS



In 2013, the Water Environment Federation (WEF), the Water Environment Research Foundation (WERF), and the National Association of Clean Water Agencies (NACWA) collaborated to develop The Water Resources Utility of the Future: A Blueprint for Action. The Blueprint coined the phrase, "Utility of the Future (UOTF)," to recognize the fundamental shift in the way America's clean water agencies were beginning to transform their role(s) in society: from simply managers of waste to broader managers of valuable resources. Recent action associated with the UOTF concept has focused on energy and materials recovery/reuse, water reuse, green infrastructure, and the use of innovative technology in operations and planning. While early successes of the UOTF have been evident for those utilities embracing it (reduced operations costs, increased revenues, local/regional economic development, etc.), there is also a compelling need for utilities to review the manner in which they function organizationally, including the provision of workforce/workplace flexibility, technology utilization and training, and performance monitoring and motivation to foster a work environment that attracts an energized staff that is not only adaptable to the UOTF notion, but one that helps to transform our industry's service providers into becoming [b][i]Employers of the Future[/b][/i]. We invite utility managers, utility staff, and workforce development professionals to attend and participate in this interactive session on what it means to be an "Employer of the Future" in our industry. The session will include an opening presentation from a utility leader that has worked to address the following workforce issues; adapt to a changing workforce demographic, provide desired workplace flexibility to their employees, create dynamic career development and advancement opportunities, and develop the ability to apply innovative technologies as clean water stewards. These efforts have produced greener and healthier ecosystems, increased utility revenues, and expanded local economies and career opportunities. Attendees will then have the opportunity to break out into small groups to discuss related, specific topics in the areas of employees of the future (intern programs), current employee programs (Young Professional and Operator issues), recruitment programs (veteran hiring) and senior employee engagement programs (post retirement options).

The Miami Dade Water and Sewer Department (MDWASD) is one of the largest utilities in the U.S. and is currently in the process of implementing a $6 billion program to comply with the 2008 Florida Ocean Outfall Legislation (OOL). The OOL requires that MDWASD WWTPs cease using ocean outfall as disposal method by 2025 and implement 117.5 mgd of additional reuse. The OOL Program includes upgrading conveyance system with more than 1100 pump stations to meet future peak flows that will account for changes due to climate change, including sea level rise. The OOL program also includes upgrading MDWASD three WWTPs and build a brand-new west district 250 mgd membrane bioreactor plant to comply with the new regulations and to harden these facilities for storm surge and sea level rise. The system peak flow will increase from 800 mgd to approximately 1290 mgd. In addition, the program is contemplating building a 7 mile, 25-foot diameter tunnel to move flows to the new west district wastewater treatment plant. This session will discuss the challenges of upgrading one of the largest wastewater treatment systems in the U.S. to enhance resiliency and compliance with the OOL. This session will also focus on the utilities perspective of implementing a large wastewater infrastructure program.

404 Balancing Flocculent and Granular Growth for BNR Processes: Knowledge Development Forum


Focus Area: Leading Edge Research and Innovation; Municipal Wastewater Treatment Design



This knowledge development forum will begin with an overview of the aerobic granular sludge and the fundamentals of its growth conditions and its physical, chemical, and biological characteristics. The bulk of this session will feature the findings of the Water Environment & Reuse Foundation (WE&RF) research project "Balancing Flocs and Granules for Activated Sludge Process Intensification in Plug Flow Configurations". The main objective of the research is to develop mainstream biological nutrient removal (BNR) processes that balance flocculent and granular growth to intensify existing activated sludge systems. The project team will share whether they proved the four hypotheses of the work:

1. Discrete and dense particles can be selected in a plug flow bioreactor configuration when the influent wastewater has a minimum fraction of readily biodegradable COD (rbCOD) to initiate granule formation, and settling selection is applied.

2. External settling selectors will allow for poor-settling microorganisms to be selectively wasted, and granular sludge to be retained.

3. If a wastewater treatment plant has an anaerobic selector, an external settling selector will stabilize bio-P removal by selectively retaining PAO-containing granules. This mechanism could allow for bio-P at short SRTs (less than one to two days).

4. Even if no anaerobic selector is present, selection of granules can create microenvironments that allow PAOs to perform due to diffusion gradients without a granule structure.

The rest of the session will involve a discussion with utility representatives and consultants on what they have experienced and seen with granulation. This will include an update of the first Nereda pilot plant in the US. The interaction between the audience, WE&RF research project team, and other panelists will help inform WE&RF of future research needs and next steps to better understand the use of aerobic granular sludge for nutrient removal.

Customers of water utilities expect – and in some cases – are used to immediate response to disruptions in water/wastewater services as is delivered by energy and telecommunications providers. However, a underground assets age, become less reliable and more prone to failure, they are subjected to natural disasters and extreme weather events. Under these conditions many utilities can no longer guarantee such high levels of service. Engineering for the most extreme events or for 100% failsafe systems are not economically feasible or practicable, so different solutions are needed where water and wastewater system "resiliency" is established through pragmatic, risk-based prioritisation approaches. Come to this session to hear three different approaches to unforeseen events which upset or could disturb the normal provision of water services.

615 Envision: Successes and Challenges After Five Years of Implementation in Utility Projects


Focus Area: Municipal Wastewater Treatment Design; Resiliency, Disaster Planning and Recovery; Stormwater, Green Infrastructure, and Wet Weather; Sustainability and Climate Change; Utility Management, Leadership, and EMS



The overall purpose of the session is to share information regarding the use of Envision in the water sector – specifically wastewater and stormwater systems. Envision was released in 2012 to provide guidance on sustainable practices in infrastructure planning, design, construction, and O&M as well as provide a rating system for scoring project achievements. To date, nearly half of the Envision projects come from the water, wastewater, and stormwater sector. Much like LEED in its infancy, it has taken a few years for Envision to gain name recognition and credibility. Given that our industry is experiencing an upswing in interest in triple bottom line and sustainability-based planning and design, Envision has proven to provide a convenient and comprehensive vehicle to apply these concepts to projects, thus increasing its popularity over the last couple years. Municipal utilities, both large and small, along with many consulting firms have embraced Envision as a viable method to practice and permeate sustainable practices into their projects. There are now several water related projects that have successfully used Envision to enhance project sustainability, navigated the Verification process, and now endorse the use of Envison on an agency-wide level. This session will include speakers from Envision's parent organization (the Institute for Sustainable Infrastructure or ISI), municipal utilities, and consultants.
