How is a project aimed at upgrading a drainage system accurately described?

A project aimed at upgrading a drainage system is accurately described by focusing on functionality, as the primary purpose of such a project is to enhance the efficiency and effectiveness of water management. Upgrading a drainage system involves assessing current capabilities, identifying problem areas, and implementing solutions that ensure proper water flow, reduce flooding, and prevent erosion.

Designing for function means that the upgrades will directly improve how well the system works, making it more reliable in handling water runoff and managing stormwater. This could involve installing more efficient pipes, adding retention basins, or improving grading to direct water flow.

In contrast, options like implementing cost-cutting measures, designing for aesthetics, or improving wildlife habitats, while potentially important factors in some types of projects, do not specifically address the core goal of a drainage upgrade, which is to ensure that water management systems operate effectively to protect both property and the environment.
