What is a common feature of all drainage systems?

Efficiently managing runoff is a fundamental characteristic of all drainage systems. The primary purpose of a drainage system is to collect and direct rainwater or melted snow away from infrastructure and property to prevent flooding, erosion, and water damage. A well-designed drainage system ensures that runoff is effectively channeled through appropriate means, whether through gravity flow, infiltration, or controlled discharge.

This aspect of drainage systems is crucial regardless of the specific design or local regulations, as all systems must address the challenge of surface water management effectively. It's important to note that while drainage systems may have varying design elements or maintenance requirements based on their location and specific needs, their primary function of managing runoff is universally applicable across different systems and environments.
