By default in Project Zomboid, the water and power will turn off after a certain amount of days specified in your Sandbox settings. However, using the mod “Water and power controls” you'll be able to toggle these whenever you would like on your server, giving you and your players a more relaxed experience.
1. Install the mod, if you don't know how to install mods, you can refer to our guide here.
2. Once you have the mod installed, login to your server as an admin.
3. In the chat box, you can run the following commands toggle the water and power (choose either on or off):
/globalpower on|off
/globalwater on|off
4. Enjoy your server being able to toggle the water and power.
