The Technical Practice Committee (TPC) of the Water Environment Federation (WEF) is updating its manual of practice titled Existing Sewer Evaluation and Rehabilitation, first published in 1983.  The publication will be produced following the TPC’s consensus review procedures on a 20-month schedule and is scheduled for publication in September 2007.  This Third Edition of the manual will cover such topics as the history of sewer development, methods of structural and hydraulic evaluation, and sewer rehabilitation methods and materials and their effectiveness. The manual is being written and updated for use by plant superintendents, collection systems employees, managers of plant operations or maintenance, engineers, public officials, professors, and consulting division managers.

The development of this publication is being led by Susan Moisio, of CH2M Hill, Cincinnati, Ohio, and Sean Fitzgerald, of Hazen and Sawyer, Cincinnati, Ohio.  Lead authors for this publication include Kelly Derr, of Hazen & Sawyer, Oxford, North Carolina; Ed Kelly, of CK Industrial, Brunswick Hills, Ohio; Wayne Miles, of CDM, Raleigh, North Carolina; Sean Murphy, of Bergmann Associates P.C., Rochester, New York ; Nancy Schultz, of CH2M Hill, Cincinnati, Ohio; and Charles Wilmut, of GSWW, Inc., Dallas, Texas.  Other participants on this project include Antonio Almeida, of Halff Associates, Dallas, Texas; Jim Baddaker, of Freese & Nichols, Inc., Dallas, Texas; Dave Badgley, of Sancon Technologies, Burbank, California; John Barton, of R.
