Quest: not applicable
Activating water towers is an optional activity providing you with additional income. Aside from obtaining another safe zone you also create a place to live for the city's residents. After activating a water tower you must choose a faction to give it to. This will change the city. The recording can be found on the very top of the tower. Right next to the valve that will activate the entire water tower, there is a cassette with the recording.
Important information. Collect this recording before activating the tower, otherwise it may disappear.
