Summer City Flood Prevention Program

Summer City Flood Prevention Program (夏期都市水害防止プログラム) is a large-scale disaster prevention program conducted in Academy City in order to test underground passageways' effectiveness during a flood.

Principles
Apparently only used in places that has underground streets and passageways like in District 7, though it also takes place in the entire city and can includes some above-ground roads, the program has the underground deliberately flooded for a time by guiding river water into them after passing it through water purification equipment in order to test the underground's drainage equipment and emergency shutters. This, however, essentially turns all the city's shortcuts into flowing pools. The program apparently allows for people to swim in the pools.

The only known time this program took place was in the summer one year before the main story, the same one where Kamijou Touma and Shokuhou Misaki finally told their names to one another.
