Arklay Treatment Plant
From Resident Evil Wiki
The Arklay Treatment Plant was owned and used by Umbrella Chemical, inc..[1] It was connected to the Raccoon City Underground Research Facility via an elevator, and was connected to the Umbrella Corporation Management Training facility via the same way.
It was once used for sewage handling and treatment. It was later abandoned due to its inability to process any more industrial waste, which Umbrella dumped. This coincided with James Marcus' attack on Umbrella with the intentional spread of the tyrant virus. The place became infested and anyone remaining were attacked by the leeches and became Zombies.[2]
