A system for controlling flooding comprises a fitting coupled to a preexisting drain pit in a building, a pipe connected to the fitting and having a portion extending upwardly therefrom, and a first drainage line extending from the pipe to a drainage area for discharge of water from within the drain pit. Air taken in through the air intake is directed toward a rotor that is able to rotate relative to the rest of the projectile. The at least one projection is coupled to the other of the circuit board and the electronic component and is retained against linear movement along the first axis. A user inputs data concerning a particular topic, and the algorithm processes the data to generate and display a set of recommendations or analyses.
