I was exploring the basement in my apartment building the other day. We have a room with fire system pumps and pipes and a big metal lid in the floor. I immediately thought of "the hole" at Glenn Dale Hospital LOL. Anyway, with a shovel I pried open the lid and wouldn't you know it, it looks like the same damn scary hole. Ours is about 2.5 feet in diameter with a drop pipe off to the side just like in the picture, and goes down roughly 7 to 10 feet deep. It is rigged up with a high-low level alarm. Sump pump, water well or fire system reservoir, I really don't know!
