Ellis S. Chesbrough’s Hydraulic Jacks

Origin
Ellis S. Chesbrough was an engineer who designed the Chicago sewer system and raised the streets and buildings of Chicago several feet to put in this new system. Many of the buildings were either rebuilt or physically raised with hydraulic jacks. Although the raising was successful, the sewers were not, as they let pollution travel into the water supply.

Effects
Each jack can lift up any building several feet in the air. While lifted, the nearest sources of drinkable water will become unclean.
