WEF Wastewater Manual, Edited by Freese and Nichols, is Published

The Water Environment Federation (WEF) has updated its authoritative resource for the wastewater utility industry, and the new edition was edited by a team from Freese and Nichols.

Cover of Wastewater Collection Systems manual of practice

Wastewater Collection Systems Management, WEF Manual of Practice No. 7, Seventh Edition provides extensive guidance to managers and superintendents of wastewater collection systems. The 254-page manual covers best practices for operating a wide range of conveyance facilities — including gravity sewers, lift stations, force mains, and more — as well as the financial, safety, personnel and customer relations aspects of managing a wastewater system. 

This seventh edition is the first update to the manual since 2009, and the updates overseen by the Freese and Nichols team bring the guidance up to today’s standards. In particular, the updates reflect advances in the field of asset management; changes in the regulatory environment; new strategies for capacity, management, operations and maintenance (CMOM) programs; and modern channels for communicating with the public.     

“This isn’t a design manual; it doesn’t teach you how to size pipelines or calculate flows,” explained Robb Otey, Associate in Transmission and Utilities, who was one of the primary editors. “What it does do is educate city managers and high-level officials about all aspects of their systems, enabling them to speak knowledgeably with their engineers and relay information. 

“This manual is the national standard for wastewater systems, and Freese and Nichols is honored that WEF selected us to review it. This work really speaks to the expertise of our whole utilities team and the level of service we provide to our communities day in and day out.” 

You can download the new manual from Access Water, WEF’s digital content platform, or order a printed copy from the WEF store.  

Our Contributions 

The Freese and Nichols effort was led by Cullen Carlson, Bryan Jann, Mazen Kawasmi, Robb Otey and Steven Rhodes, who each oversaw two of the manual’s 10 chapters. Additional employees across four practices — Water/Wastewater Transmission and Utilities, Water/Wastewater Master Planning, Water Resources Planning, and Construction Management — contributed editing and research, as did our Funding, Safety and Communications specialists. The process also involved incorporating feedback from 18 professionals throughout the industry over multiple rounds of reviews.
