Freese and Nichols Contributes to WEF’s Comprehensive Guide on Sewer Evaluation and Rehabilitation

As our infrastructure ages, the need to rehabilitate existing sewers becomes increasingly important. Prolonging the lifespan of current sewer lines is an economical approach that lessens the financial burden on clients. In response to this growing need, our firm has contributed to a new manual titled “Existing Sewer Evaluation and Rehabilitation,” published by the Water Environment Federation (WEF).

This seven-chapter manual provides an exhaustive source of information on the upkeep, repair, rehabilitation, and substitution of existing sewer systems. It stands as an authoritative resource encompassing aspects of sewer assessment and surveillance, methods and materials used in sewer rehabilitation, and quality assurance.

The manual equips design engineers with the essential knowledge required to formulate an all-encompassing evaluation and rehabilitation plan for sewer systems. It is organized in a way that initially focuses on the establishment of an effective rehabilitation program. This is then followed by in-depth sections discussing the processes of evaluation and rehabilitation. The guide wraps up with a section dedicated to assessing the outcomes.

This is the third straight year that Freese and Nichols has updated a manual for the Water Environment Federation (WEF) and is scheduled to start the next manual this fall, which includes our Treatment Group.

Here is a link to where the manual can be found online, now available for purchase.
