Lake Pump Removal

So we had a fun job today. Little background on the system: 30+ year old system that we did not install. See my pictures in the "Hacks" thread for other pictures from this complex.

Basically a 480v 3 phase pump that was causing the breaker to trip every time it kicked on. All testing showed that the pump motor and wiring were fine, but the well end on the pump was bad. Only problem was, no one knew where the damn pump was (except it was in the lake which is about 28 acres, 100' deep with steep sloped sides (old stone quarry)).

Discharge pipe was visible from the breakwall, down 6' feet under water, which was 8' from the shore (lake has risen over the last 30 years to cover the breakwall and create a new shore line) so we had to use road plates to create some type of bridge between the shore and the breakwall.

Our job was to find and remove the pump no matter what, and that is what we did. We knew that all the previous piping was going to be not used so we went ahead and removed that too.

Pictures from the fun below...

You can see the breakwall out in the water, which was the reason for the road plates for support.
