Gravity drains are systems designed to remove excess water from an area by using the natural force of gravity. They typically consist of pipes or channels that allow water to flow downhill, away from structures or landscapes, preventing flooding and water accumulation. These drains are commonly used in agricultural fields, construction sites, and urban areas to manage stormwater. By directing water to designated drainage areas, gravity drains help maintain soil health and protect infrastructure from water damage, making them an essential component of effective water management systems.
