MISSION Commencement
This mission is accessible under two circumstances: (1) you finish Story Mission: Sins of the Father and return to speak to Virgil Minkler at Hope County Jail, or (2) when you liberate the jail and pass the Deep North Water Treatment Plant, you receive the mission over the radio.
REACH the Water Treatment Plant
FIND a Way to Get in the Pump Rooms
The water treatment plant is extremely well guarded; expect around 10 enemies and a VIP within the plant’s rather porous perimeter.
Note the seven different gaps (
-
) you can enter the plant from; there are more if you’re heading from the inside out, as you can use stacked crates to jump the fence. You could also zip-line from the southwest rocks 
to the roof of the pump room (
1). After you destroy one of the pump rooms, expect at least two pickups with mounted weapons to arrive from the southeast road near 
, along with at least eight more foes. Finally, note the person-sized connecting underground pipes that run from the treatment ponds to their associated rooms; this is the only way to reach the pumps to destroy them.
Note that some narrow blue pipes with arrows on them indicate where you need to maneuver when navigating under the plant.
OPTIMAL Path
If you execute the following plan perfectly, you won’t need to fight the reinforcements that automatically arrive. To do this, you require a remote detonated explosive. Bring one or more, then crouch and execute a stealth attack on the enemies. Enter via the gap in the fence at 
. Wait for the VIP to move to the nearby open container by the parked truck to your right. Then strangle him (as he otherwise takes multiple shots to bring down, thus raising the alarm). Then conduct a silenced-weapon takedown of all remaining 10 foes, moving around the inside of the southern perimeter from 
to 
, tagging foes in the vicinity. Then creep to the left of the pump room (1). Hide here as you drop foes in and around the two rectangular pools and the circular pool. Work from the outside in.
With the entire area quiet, pick pump switch (2) at the circular pool, press it, then enter the underground pipe below 
to the pump control room (also (2)). Set a remote explosive on the middle pump so the explosion destroys all three pumps (this is important!), but don’t detonate the explosive yet.
Wade back along the underground pipe, climb out of the circular pool, and head to the rectangular pool (1). Shoot the barrel and debris blocking the underground pipe in the second pool, then follow the pipe to the pump room (also (1)).
Now detonate! The pumps in room (2) are destroyed. Now quickly place a charge on the central pump in pump room (1); destroy the three pumps here, and escape via the locked door, which is now accessible. Leave the same way you came in, just before the reinforcements arrive.
Remember! Don’t detonate the explosive in the first room unless you want to fight reinforcements; this path negates that necessity!
OTHER Paths
The general path remains the same, though it doesn’t matter which pump room you destroy first. You can remain in the room too; it offers the best defense as foes can only use the doors to enter. Just remember one room has two exits and the other has three; don’t get outflanked!
There are other methods of infiltrating the plant yard: the zip line near 
; the trail to the west 
that leads to the white pipe sections 
; the outbuilding roof south of 
; and even the road entrance at 
, if you’re bringing an ally in a vehicle with a mounted weapon.
If you must fight the reinforcements, destroy the pump room (2) first, so you can quickly prep the road near 
with explosives, or ambush from the upper woodland to the east.
The roofs of either pump house make good height and cover locations for fighting enemies if stealth is unimportant.
After you destroy the machinery in both pump rooms, the mission concludes.
