I went onsite to witness the water main excavation identified by the red circle. The Village was repairing a leaking valve by excavating at the intersection and installing a line stop. This excavation was 15’ east of the water main valve and adjacent to a storm sewer trench. While there was water entering the excavation from the leaking valve a large amount of groundwater entered the trench from the stone bedding of the adjacent 48” storm sewer. The ground was relatively dry however the stone bedding was saturated. The ground was a silty clay and in some areas had trench walls that stood to a depth of 4’ - 5’. Through pumping (2” and 3” pumps) the Village was able to lower the groundwater within the excavation. I asked them to take readings on the adjacent monitoring well located across the street to the west both during and after the excavation. I will keep everyone posted of the results.
