There is going to be a new well house built in my area. This well house doesn't pump water but it pumps raw sewage. The wet well is about 27 feet dep and there is 2 sumpmersible pumps in there. There is a ladder going down into the pump area so people can maintain these pumps. The question becomes, Is there a code that says there has to be a light fixture inside the wet well? There are 2 large "bilko" steel doors over top of this well pit. The people who are building it say that lights aren't required because you would not go down inside the pit at night. Any work done inside would be done during the day. Anybody see any code sections that would require these lights? One reason they don't want to put lights inside of pit is because they would have to be explosion type lights.
