6. No, you can't have described it correctly |

Pumping water uphill takes more energy than you can get from it coming down again.
Perhaps the water that's pumped uphill comes from another source, that's higher than bottom of the hill? There might conceivably be some reason for doing it that way - you need a minimum head of water to run the generator they have, for instance. It would still be inefficient, overall, but it might be a question of the size of the equipment they have already available.
