Copublished by WEF Press and ASCE Sponsored by the Water Environment Federation and the Environmental and Water Resources Institute of the American Society of Civil Engineers Sustainability and Energy Management for Water Resource Recovery Facilities, WEF MOP 38 / ASCE MOP 137, describes the best practices for evaluating and improving the energy management and sustainability of wastewater treatment plants. Global climate change, volatile energy prices, and other potential forces of change require designers to plan and design water resource recovery facilities (WRRF) that are sustainable—less costly to operate and maintain over a plant’s full life cycle and more resilient to near- and long-term change. This Manual of Practice begins with an assessment of commonly used sustainability frameworks. It then offers guidance on the practical application of sustainability concepts at key decisions points during the planning, preliminary design, final design, construction, and operational phases of WRRF capital projects. The volume discusses strategies, tools, and references that are globally applicable and helps in planning projects that meet today’s expectations for WRRFs: significantly reduced energy consumption, modern automated equipment with less downtime, lower operation and maintenance costs, resiliency to weather extremes, lower chemical inputs, and marketable products through resource recovery. WEF MOP 38 / ASCE MOP 137 is a companion volume to Design of Water Resource Recovery Facilities, Sixth Edition, and will be of interest to environmental and wastewater engineers, facility managers, and others working on modern wastewater treatment plants.
