Abstract:

The Augusta Sanitary District is implementing the second of its four-phase Long-Term Control Plan for the abatement of its combined sewer overflow discharges. The current program focuses on the West Subsystem with the key component being the West Side Consolidation Conduit (WSCC).

Proving out design and construction for anticipated performance is troublesome for engineers, contractors and equipment vendors. Components, systems and the construction usually have to await long periods after initial startup to be subjected to “real life” conditions of sewage flows and solids to be demonstrated. Often, much of the typical 1-year warranty can be consumed especially for CSO projects which require significant wet-weather events to occur. For the Augusta Sanitary District's (ASD), Augusta Maine CSO Abatement project, a unique synthetic performance test was developed and demonstrated allowing early verification of sequential in-line flushing effectiveness for the self-cleaning of a hydraulically long CSO consolidation conduit.
