Utilities are the additional resources required for some objects to work. There are two kinds of utilities: power and water. Most objects only need one utility, though others require both - such as the Laundry Machine. The Utilities tab is found in the Menu.

Some objects require a "direct" water or power connection, where the object must have the relevant utility attached directly to it, be it water from a Water Pump Station using small or large pipes, or power from a Power Station using Electrical Cable. In order for such an object to be considered connected the appropriate utility line must run from a working source to directly underneath it.

Small electrical items such as TVs, radios and lights do not require direct connections, but merely need for there to be an electrical cable within a close distance. Other objects such as surveillance equipment, door servos and kitchen appliances require a direct connection to function.
