Project Description
Client: Alpine Home Builders
Location: Driggs, Idaho
Year Completed: 2023
This particular sewer connect included a four-building apartment complex. Engineering called for a single 4″ line from each building. In order to meet code, we had to excavate a large portion of the sewer mainline (City of Driggs). Groundwater was a problem that required us to perform this installation in late summer and required the use of pumps to keep the trench clear.
The Challenges
Excavating sewer mainline is always a difficult chore. This specific mainline did not have tracer wire, and could not be located. We ‘Witched’ the dig area and roughly located the mainline. Upon excavation, groundwater was present. We had to make the call to bury the excavation and return later in the year. Groundwater was still present, but had dropped several feet. A 4″ trash pump was used to keep the excavation area dry while making the hot taps.
