What is a result of poor drainage capacity in a system?

Poor drainage capacity in a system leads to Clogging and backups. When a drainage system cannot effectively handle the volume of water it is designed for, the water can either back up in the system or create blockages due to debris, sediment, or other materials that accumulate. This can obstruct normal flow and subsequently cause flooding in areas that rely on that drainage system.

A well-designed drainage system should facilitate the efficient removal of excess water, preventing any interruptions in flow. When drainage capacity is compromised, it can result in a myriad of issues including, but not limited to, property damage, increased maintenance costs, and unsanitary conditions. The other options do not accurately represent the consequences of poor drainage capacity, as they either suggest enhanced conditions (such as increased flow and effective transport) or economic benefits (reduced material costs) that would not result from drainage issues.
