Standards for Design of Water Resource Recovery Facilities ,WEF 8 is intended to complement the evolving contemporary design references of today. WEF 8 provides ready access to concise critical design information and enables the reader to quickly locate additional information by following cited references. This standard is formatted to present key design criteria from a variety of design resources on tables and bulleted lists for easy access. WEF 8 is intended for seasoned design professionals familiar with wastewater resource recovery concepts, the design process, facility operations, and the regulatory basis of water pollution control. This reference will serve as a design tool to quickly identify the most relevant design criteria for the more commonly used water resource recovery operations and processes. It is recommended that the reader not rely solely on information presented in this standard as it is not inclusive. A thorough understanding of the principles behind these summary chapters is necessary for the correct application and use of all information contained in this reference.

In the last 10 years, there has been continued changes in solids management. For example, incineration, which was a viable disposal method, has been affected by U.S. EPA’s Sewage Sludge Incinerator (SSI) rules. Emerging compounds, such as PFAS/PFOAS have affected land application, with at least one state banning land application of biosolids. Intended for use by professionals engaged in the design, approval, and operation of solids treatment and disposal systems, this update addresses many of the changes that have occurred over the past decade, incorporating material published as recently as 2022. Wastewater continues to require increasing levels of treatment, especially as we begin to consider our facilities as water resource recovery facilities. This will yield more solids that, at the least, need to be managed in an efficient and effective manner to protect human health and the environment. Preferably, we can treat these solids as resources, recovering biogas from the digestion process and phosphorus from the biosolids. It is highly recommended that design standard setting organizations embrace the changes incorporated in this design publication. Recommendations in this publication represent best practices that go well beyond the minimum design requirements necessary to comply with requirements of U.S. EPA’s Standards for the Use or Disposal of Sewage Sludge (40 CFR Part 503). This is increasingly important for biosolids management to remain viable and environmentally sustainable in the future.

In recent years, the importance of planning for and responding to infectious disease outbreaks has become increasingly evident. It is imperative to make the protection of water professionals, public health, and the environment a priority during the uncertainty of an outbreak. The Water Professional’s Guide to Infectious Disease Outbreaks will help you understand and evaluate the vast amounts of information produced during outbreaks and make evidence-based decisions to protect both water professionals and the wider community. The publication covers pathogens, treatment practices, risk assessment, health and safety evaluation approaches, adaptations in facility management, communications, and wastewater surveillance.

This Manual of Practice presents current design considerations for wastewater and stormwater pumping stations. It covers station capacity requirements and configuration, the selection and design of pumping equipment, piping system layout and hydraulic considerations, electrical and instrumentation systems design, and other station appurtenances. Intended for design professionals, it addresses design of stations of all sizes and highlights the differences between wastewater and stormwater stations.

This manual includes laboratory procedures most often performed in wastewater laboratories and includes general wet chemistry procedures, activated sludge process control tests, bacteriological testing, and special sections about basic laboratory techniques and proper use of spectrophotometers and colorimetry. Each method (procedure) is broken down into easy-to-follow, step-by-step directions that adhere to recommendations found in Standard Methods for the Examination of Water and Wastewater and approved U.S. Environmental Protection Agency guidelines. Each method (procedure) includes a sample benchsheet. The intention of this publication is to help the operator–analyst produce analytical data that are defensible, precise, and accurate for process control and permit reporting. Special emphasis is placed on quality assurance and quality control. The introduction to each method includes a brief discussion of why the test is performed and how it can be used for process control. Most methods include typical ranges for the parameter associated with different types of treatment processes. This information will help the operator–analyst determine the appropriateness of the collected samples and if results are reasonable.

The effectiveness of stormwater management programs depends largely on how well and how safely stormwater control measures (SCMs) perform over time. The importance of maintenance and the significant numbers of SCMs have created the need for guidance on how stormwater programs must adapt to address evolving SCM design and maintenance requirements, climate change and resilience, and integration of asset management concepts to reduce long-term program costs. This manual meets that need with best practices for maintenance programs, as well as case studies to show how a variety of utilities have implemented them. The material covered will be of particular use to designers of SCMs, utility managers, and O&M staff.
