Figure 4. Inside one of the manholes of the sewer system in the Boston flow study (looking into Pipe A, as illustrated in Fig. 2). One of the FlatPack Level Sensors can be seen mounted at the top of the 8-inch diameter Pipe A.
The entire program consisted of three separate flow studies that were carried out between January and June of 2017. During all three of these studies, the FlatPack Sensors were able to accurately measure the level of water in the pipes, which allowed for precise and repeatable measurements of the water flow during the entire flow study program. As a result, the maximum additional flow into the sewer was established, allowing the municipality and college to agree on additional allowed inflows and ancillary drainage planning. With the study completed, the college was granted approval to expand the requested infrastructure. WW
