Grit occurs naturally in sanitary sewage, and given adequate velocities in the collection system, will be carried to the treatment plant. Grit depositions have a significant impact on collection systems, including odors, blockages and impacts on inspection. Sediment transport has been shown to cause invert corrosion in an interceptor sewer.

The Large Diameter Sewer Condition Assessment and Inspection Program (Assessment Program) consists of approximately 1.37 million feet of 15- to 42-inch sanitary sewer of which approximately 80% has been inspected. An objective of the Assessment Program is to determine the impact grit is having on the City of Phoenix interceptor system. The scope of our contract is to evaluate grit deposits in the collection system, estimate the volumes, evaluate grit reaching the area-wide interceptor operated by the Sub-Regional Operating Group (SROG) and evaluate grit removal. The focus of this paper is on our efforts to predict depositions of grit compared to the actual field locations at which grit caused problems.
