    Municipal sanitary sewer collection and conveyance systems are an extensive, valuable, and complex part of the nation's infrastructure. Collection systems consist of pipelines, conduits, pumping stations, force mains, and all other facilities used to collect wastewater from individual residential, industrial, and commercial sources and convey it to facilities that provide treatment before discharge to the environment.

    Unfortunately, the current performance of many collection systems is poor, and many systems have received minimal maintenance for many years. Wastewater collection systems also suffer from a history of inadequate investment in maintenance and repair due in large part to the "out-of-sight, out-of-mind" nature of these systems. The poor performance of many sanitary sewer systems and resulting potential health and environmental risks highlight the need to optimize operation and maintenance of these systems.

    With that need in mind, NEIWPCC has undertaken a variety of efforts to address the improvement of collection system operation and maintenance.

  • Learn about collection system operation, maintenance, and rehabilitation guidelines and go to the NEIWPCC comprehensive manual titled Optimizing Operation, Maintenance, and Rehabilitation of Sanitary Sewer Collection Systems.
  • Learn about a model evaluation method for conducting Capacity, Management, Operation, and Maintenance (CMOM) assessments and visit the NEIWPCC CMOM project page.
  • Learn about controlling and managing Fats, Oils, and Grease (FOG) issues in the collection system.
  • For additional information to support effective collection system operation and maintenance visit the Collection System Resources page.
