What kind of plumbing system is used to prevent flooding in areas with high water tables?

A sump pump system is specifically designed to prevent flooding in areas with high water tables by actively removing excess water from basements or crawl spaces. It operates by collecting water in a sump basin, which is usually located in the lowest part of the home. When the water reaches a certain level, the pump is triggered to discharge the water away from the house, typically to a storm drain or exterior area.

In contrast, while drainage systems can help manage water flow and can be beneficial in preventing flooding, they do not actively remove water from a specific area like a sump pump does. Septic systems are intended for waste management and treat wastewater; they are not designed for flood prevention. Backflow prevention systems protect potable water supplies from contamination due to reverse flow but do not address flood issues caused by high water tables. Thus, the sump pump system is the most effective choice for managing flooding in such conditions.
