Utilities are faced with many challenges in their mission to manage wastewater, protect the water environment, and use resources wisely. Meeting these challenges can require significant upgrades to the nature or size of their facilities. This manual serves as a guidance document to help utility managers and others navigate this complex process.

Odor Emissions and Control for Collection Systems and Water Resource Recovery Facilities, 2nd edition, is intended to be the primary reference document for current standards of practice for professionals involved in odor control at wastewater treatment facilities and collections systems. This manual covers all aspects of odor control in wastewater conveyance and treatment facilities, including the basics of odor testing and emissions, sensory analysis, local and state regulations, public outreach, and the technologies used to treat odors. Odor testing and control have undergone rapid advancements since the publication of the first edition of the Water Environment Federation's Manual of Practice 25, Control of Odors and Emissions from Wastewater Treatment Plants. The second edition brings an expanding body of knowledge and real-world experiences to the reader, and it embodies the current state of practice in the industry. The entire manual provides a comprehensive look at all aspects of odor control in the industry today. A new feature of this manual not included in the 2004 edition is the chapter entitled "Collection Systems," which addresses ventilation of sewers, air treatment, and chemical treatment. Odor control in water resource recovery facilities (WRRFs) and solids handling facilities are also covered extensively. This manual also presents best available biological, chemical, and physical technologies for controlling odors; information on analyzing, measuring, and sampling odors; and tools for assessing odor impacts in surrounding neighborhoods and communities. In short, this manual teaches the proper aspects of how to be a good neighbor and share clean air around a treatment facility, while still providing indispensable wastewater services to the larger community.

Provides a detailed resource on planning, design and construction of trenchless rehabilitation technologies for pipelines carrying drinking water. Trenchless renewal, rather than open-cut pope replacement, offers a variety of benefits, including lower risk of damage to surrounding area, fewer traffic disruptions, better public safety, and shorter completion times.

Focuses on the technical aspects of modernizing irrigation systems through the use of automated canal control systems. Using information collected from irrigation systems around the world in conjunction with new advances in control theory research, this Manual of Practice examines how and when to implement canal automation within the context of canal modernization.

Addresses the design of major pipeline or duct segments to be installed by horizontal directional drilling (HDD). Topics include predesign surveys, drilled path design, pipe design, construction impact, and as-built documentation. This new edition captures advances in drilling equipment, improvements for tracking, and considerations for using alternative pipe materials.
