One-Voice for Sewer Condition Assessment Data

Speakers: Phil Lewis, Ph.D., P.E., Assistant Professor; Hossein Khaleghian, Doctoral Candidate; and Yongwei Shan, Ph.D., P.E., Assistant Professor, Oklahoma State University


Although there are widespread claims that the nation’s sewer infrastructure is failing, these claims are often undocumented except in the region where the sewer is located. There is a need for a national inventory to publicly present empirical data that accurately represents the condition of sewer systems. The benefits of such an inventory include: empirical data to justify increased spending on failing infrastructure; benchmarks of the national sewer infrastructure by region; identification of deterioration mechanisms in sewers; and a means for national dissemination of the data. This session reports on collaboration between Oklahoma State University, the National Association of Sewer Service Companies (NASSCO), and several sewer industry consultants to develop a unified inventory of sewer pipeline condition assessment data called One-Voice, addressing its strengths, weaknesses, opportunities and threats.
