Q. What is the capacity of our sanitary sewer system (minus the plant)?

A. The capacity of the sanitary sewer system, minus the plant, varies depending on location. Upstream pipes serving individual neighborhoods (typically 8-inch diameter sewers) have a capacity large enough to meet the needs of a smaller area, and downstream interceptors serving large portions of the City have a higher capacity. The key item is the capacity of the pipe, compared to the expected design flow under wet weather conditions. These values will be developed for the trunk sewers and interceptors in the Sanitary Sewer Wet Weather Evaluation (SSWWE) project.
