I discovered this Big Green Pump a week ago. It must be quite a project, as now there are more pipes stacked and additional barriers. I walked off to the left, and a crew of guys were installing mini-bridges across the curb-edges at each driveway on one side of the street. The mini-bridges had connectors at each end, I think to allow the project to pump piped water above ground down that street while still allowing homeowners to use their driveways. Still don’t fully understand the Big Green Pump project.
