Wastewater Engineering: Design of Water Resource Recovery Facilities (MOP 8 Series) provides the reader with the up-to-date knowledge and tools required to design water resource recovery facilities. It serves as both a textbook for senior level and graduate students in civil engineering and a reference work. The scope of coverage and the classroom-friendly features, such as learning objectives and example problems, makes it an excellent tool for students transitioning from academia to practice, and it remains an essential resource for practitioners. Written by a team of professors and consultants and put through a rigorous industry review, Wastewater Engineering provides vital WRRF design information to an engineer at every stage of their education and career. Wastewater Engineering has its roots in WEF’s Design of Water Resource Recovery Facilities (MOP 8), a long-time fixture on the design engineer’s shelf. As WEF approached how to update MOP 8, the organization decided to do so in a way that would address two significant needs in the water sector. The first was the need for current, nationally applicable, peer-reviewed design standards. The result was Standards for Design of Water Resource Recovery Facilities (WEF 8). WEF 8 is a tool for seasoned design professionals, providing concise coverage of critical design criteria that has been formatted in quick-reference tables and bulleted lists. The second was the need for a wastewater design textbook and reference, as covered by this book. Within the MOP 8 series framework, this textbook serves as the entry point for new wastewater engineers and a primary reference work for practitioners, providing both theory and significant context behind the design parameters covered more briefly in WEF 8.

This Blueprint represents a moment in the evolution of the PFAS story, noting that this is an iterative process in tracking PFAS. This publication targets a specific audience and purpose: utilities navigating options for addressing PFAS. Because PFAS continues to be a moving target, it adds a level of complexity in offering the latest detail. This publication offers a good historical snapshot of the considerations utilities need to make when preparing their strategies. It's important for receivers of these compounds to be informed about PFAS and to be able to effectively communicate to their customers. This Blueprint document presents best practices and resources for receivers trying to navigate PFAS issues in their communities.

2022 National Municipal Separate Storm Sewer System (MS4) Needs Assessment Survey Results

Download this report by logging in or creating an account.

The Water Environment Federation’s (WEF) Stormwater Institute (SWI) conducted the first national survey of municipal separate storm sewer system (MS4) permittees in 2018 with a follow-up survey in 2020. Like the previous two surveys, the 2022 survey results are statistically significant1 and responses were received from 47 states as well as the District of Columbia and Puerto Rico. The fundamental objectives of these surveys are:

• to identify the information and resource needs of MS4 permittees,

• to better understand MS4 program challenges, and

• to approximate current funding levels and estimated funding needs in the MS4 sector.

In addition, the 2022 survey covers topics such as well-developed, least-developed, and most innovative aspects of stormwater programs. Resilience planning was also included in the survey to capture the incidence of this planning currently and in the future of stormwater programs and the future challenges associated with it.

Approximately 93% of responses in the 2022 survey came from Phase I and Phase II MS4s. Of these responses, approximately 21% were from Phase I communities and 72% from Phase II communities. The remainder of responses came from nontraditional MS4 Phase II permit holders and state departments of transportation (DOTs). Respondents were generally representative of the geographic distribution of MS4s across the United States for both surveys.

The survey was comprised of questions to gather basic information on stormwater programs (size, type of permittee), yes/no-based questions on various aspects of stormwater issues and topics, and several multiple choice questions focusing on stormwater program challenges and needs. Weighted average scores using a 1 through 5 rating system were used in the report to efficiently capture respondent ratings in a single metric.

Responses of 4 or higher reflect strong interest or support for topics. The percentage of responses at this 1Sample of municipal respondents is statistically significant at the 95% confidence interval, with a 5% margin of error.

Polymer/Flocculants 101

The aggregation of particles into larger and more easily removable forms by employing coagulants or flocculants is necessary for efficient separation by clarification, sedimentation, filtration, or dewatering processes. The terms “coagulant” and “flocculant” are often used interchangeably. However, the discussion in this fact sheet will be focused on high molecular weight, cationic polymeric flocculants used for thickening and dewatering solids separation processes where they operate through bridging or similar mechanisms

Tertiary filtration removes suspended solids from secondary effluent at water resource recovery facilities (WRRFs). It is a polishing step following biological treatment and secondary clarification in preparation for disinfection, final discharge, or reuse. Tertiary filtration is expected to grow in application with industry trends toward more stringent nutrient removal and increased reuse of secondary effluent. This fact sheet is part of a series on liquid stream fundamentals.

WEF’s new, comprehensive toolkit provides an extensive framework for communicating about biosolids in ways that are factual, science-based, and easily understandable by those who might be hearing about biosolids for the first time. The toolkit includes guidance on some of the more challenging communication tasks you may encounter—responding to, or proactively pursuing media coverage, handling concerns raised about the safety of biosolids, creating presentations for use at events or meetings with the public, and developing content to post online or on social media. The toolkit features messages that serve as an overall umbrella that can be adapted for FAQs, talking points, community meetings, fact sheets, brochures, social media, and websites.

Plus, listen to WEF’s webcast on how to use the toolkit!
