Utilities are the additional resources required for some objects to work. Currently, there are two kinds of utilities: power and water. Most objects only need one utility (except for the washing machine). The Utilities tab is found in the Menu .
Some objects require a "direct" water or power connection.
It means what water or power must be conveyed from its source, Water Pump Station or Power Station, to a tile directly under the object, not near the object. For water it is done with a help of Small Pipe and Large Pipe; for power, with a help of Electrical Cable.
In case object does not require "direct" water or power connection, cable or pipe just need to be nearby.
