After obtaining the PUMP ACCESS DISK, as shown in the previous section....

Turn around to face the excavation pit. The gate you just came through is now closed, so take a running jump across the pit to grab the ladder on the blue support pillar. Climb to the top.

At the top of the ladder, take a standing jump up the slope on the left.

Go through the uneven, rocky tunnel with the burning barrel...

...to the fenced in opening near the TUNNEL-BORING MACHINE. Climb another blue ladder to the stairs above.

At the top of the ladder, turn left and follow the walkway to a doorway overlooking the pit.

Drop down onto the cement ledge just below the doorway.

Then turn around and climb the next set of ladders upward, to the right, and then upward again until you reach the top.

If you haven't already picked up the rocket in the small alcove to the left, do that now. Then go cautiously to the right end of the walkway. If the orange-suited worker here is still alive, he'll try to ignite the barrel below the ledge. Either shoot him before he can do this, or kill him then jump carefully over the burning barrel at the right side.

If you killed the worker earlier, the barrel may not be lit, and you can just hop down near it. Now go to the far right corner of this room...

...and jump onto the ledge next to the wrecked train engine. Climb over the engine...

...minding the gap on the other side, to get back to the portable toilets.

NOTE: If you didn't explore here earlier, you'll need to throw a switch and kill another worker in order to access the toilets, as described earlier in the walkthrough.

Go into the portable toilet on the left. Use the PUMP ACCESS DISK in the computer next to the toilet to turn on the pumps and fill the pit with water.

FLUSH!!
