During intense rainstorms, residents of urban areas rely on stormwater sewers to keep streets and homes from flooding. But in some cases, air pockets in sewers combine with fast-moving water to produce waterspouts that can reach dozens of feet high and last for several minutes. These so-called storm geysers can flood the surrounding area, cause damage to nearby structures, injure bystanders, and compromise drainage pipes.
