Mission: Clean Water Act
Region: Henbane River (Faith)
Area: Hope County Jail (receive mission), Deep North Water Treatment Plant (complete mission)
NPC: Virgil (mission giver)
After liberating the Jail in Faith's region, talk to Virgil in a room near the arcade machine. He will give you the
Clean Water Act mission.
If you don't receive this mission from Virgil before you try to kill Faith, you'll just have to go to the treatment plant and do the mission directly because...
If you can't do it before endgame,
ecinrun says you can definitely do it after endgame.
Mission objectives:
1- Reach the Water Treatment Plant
2- Find a way to get in the pump rooms
*** Spoiler - click to reveal ***There are 2 pump controls on catwalks over a couple water pools. Find a pump control over one of the pools and activate it, revealing either a blockage in front of a pipe entrance in another pool or just another pipe opening. Blow up exploding barrel in blockage and enter that pipe. Quickly get to room at end and wait for the water to rise again so you can climb up or use the ladder.
3- Destroy the pumps in each building (0/2)
*** Spoiler - click to reveal ***Distance yourself from the pumps and use grenade/dynamite or shoot an exploding barrel to destroy them. I didn't try doing direct damage to the pumps myself. So let me know if you can. Exit the pump room through the newly-unlocked door.
After destroying each set of pumps, you may/will get attacked by a wave of enemies. If you have any Guns for Hire, use them. When enemies are defeated, repeat #2 & 3 above for the other set of pumps. It's just a different catwalk, pipe entrance, and pump building for each set. One pipe has a blockage; the other doesn't. One pump room has a barrel; the other might not. Same goes for a ladder to a pump room.
Reward: 900 Resistance Points (or cash after region is cleared) and this achievement
