The pool will now fill with water.

Sewer to Asylum:

Go back to the basement where you found the wire cutters and you will be able to open the door with the huge locking device. This door leads to the sewer.

Sewer: Go down the sewer all the way to the left until you come to a dead end. Turn left and climb the ladder and then go through the manhole.

Seward's Asylum: You will be at Seward's Asylum.

Go forward into the sewer, turn right, forward once and look to your right to find a rope on the wall. Take the rope.

Continue going forward 3 more clicks until you come to a control box on your left with a little red light. Turn to your right and look down. Pick up the wheel.

Continue on in the sewer until you come to a dead end and see a ladder in front of you. There's a filled reservoir in between. Combine the wheel with the rope in your inventory and use it on the ladder. The ladders falls down.

Walk to the other side, look down and open the little tool chest. Take out the wrench.

Go back down the tunnel to where you picked up the wheel and saw the control box. Use the wrench on the wheel and take it.

Go back and cross the ladder again, but stop when you are halfway across and look at the wall to your right. You will see a notched area where you can put that wheel. Use the wrench to tighten it and then turn the wheel. The water will drain out.

Continue across the ladder, turn around, look down and take the ladder. Place the ladder against the right side of the pit vertically, so you can climb down.

At the bottom of the pit, pick up the ladder and go through forward once through the little tunnel.

Find and go to the large entrance gate to the cemetery.

Facing that gate, turn right, go forward once, then turn right about 135 degrees until you find the magnifying glass cursor on the wall of the graves area.

Get closer and use Pibody's key on the lock. Pick up the ladder.
