What is the primary objective of a site drainage system?

The primary objective of a site drainage system is to collect and convey all excess storm water. This function is crucial for maintaining the integrity of the landscaping and structures on a property. Effective drainage reduces the risk of flooding, which can lead to damage of buildings and infrastructure. By directing storm water away from areas where it can accumulate, the drainage system ensures that the water flows into designated areas, such as stormwater management facilities or natural water bodies, minimizing standing water that can lead to erosion, waterlogged soil, or structural damage.

While preventing soil erosion and managing environmental impacts are important considerations in the design and functionality of a drainage system, they are secondary to the fundamental purpose of collecting and redirecting storm water efficiently. Enhancing landscaping, although a significant benefit, does not surpass the primary objective of storm water management. Thus, the core purpose remains centered on the effective collection and conveyance of excess storm water to protect the site and surrounding areas from water-related issues.
