On Oct. 5, a manhole on Neuport Path had a subsidence (gradual caving in/sinking). Subsidence is usually caused by traffic, loose soil, and groundwater which has weakened the joints to the point of failure, leading to the “sinking” of the manhole. In this case, the manhole has sunk approximately 2.5 ft. Repair actions are currently underway as well as geological analysis and chemical grout to stabilize the soil surrounding the manhole before it is removed and replaced.
Efforts to remediate the manhole structure on Neuport Path are under way. The first step in the process is to provide a by-pass for a section of the collection system along Neuport Path. To isolate the manhole, by-pass pumping operations must be conducted in two locations. As such, pumps will be placed at the Quartz and Neuport intersection and in the vicinity of 1356 Neuport Path. An above ground, temporary, conveyance system will be placed in the utility easement between the homes from Quartz Ave. to a discharge location on Viola Ct. The second step can be initiated once by-pass operations are fully operational.
The second step will include replacement of the structure within Neuport Path road and right-of-way.
