Trumpy if you are thinking the gray line is incoming electric flex it is actually the discharge hose. Where I am in Canada the ones in the stores are ribbed like that but in black plastic.
I can see an orange extension cord tied to the chair on the left side in the second picture The two black cords (one from the pump motor and the other from the off/on float)coming up connect to the orange cord on the chair seat. The float is tied up on the top of the pump so it will run continually which is probably not good for it.
One of my neighbors did something similar one weekend last spring using a roofers pump when our back lane catch basin frozeup over night. At least he had his plugged into a GFI in his garage and orange cones around it and the cord. He had the extention cord taped to the top of the cones to keep everything out of the water.
