What is a "drywell" in the context of septic systems?

A drywell is a crucial component of certain septic systems, specifically designed to collect and manage excess water. Its primary function is to allow water to slowly drain into the surrounding soil, which helps to mitigate issues related to excess moisture and promotes groundwater recharge. By providing a space where water can percolate into the earth, drywells help prevent flooding and the buildup of wastewater on the surface.

This gradual drainage process is essential for maintaining the balance of the local ecosystem and ensuring that the septic system operates efficiently. In areas where water may accumulate or where the soil has low permeability, drywells are particularly beneficial to facilitate water management.
