What is a cesspool designed to do?

A cesspool is specifically designed to allow for the storage of solids while enabling liquids from wastewater to seep through the walls of the pit. This process facilitates the gradual percolation of liquid waste into the surrounding soil, thereby providing a degree of treatment through natural filtration. In this way, the cesspool acts as a holding system for waste materials, where solids settle at the bottom and liquids are absorbed into the surrounding ground, alleviating the need for a more complex treatment system.

The other options do not align with the primary purpose of a cesspool. Efficient stormwater drainage would typically involve different systems, such as storm drains or retention basins. Venting two fixture drains is a function of plumbing systems that focus on airflow and drainage efficiency, not the function of a cesspool. Combining multiple sinks into one unit pertains to plumbing fixtures and their configuration rather than the treatment or disposal of wastewater, which is the essence of a cesspool’s design.
