About this chapter: Chapter 10 addresses the construction of cesspools. Although cesspools were a common method for disposing of sewage for new buildings in some areas of the United States, the code only allows the construction of a cesspool as a temporary measure until a proper sewage disposal system can be installed.
Cesspools shall conform to the construction requirements of Section 605.3 for seepage pits. The seepage pit shall have a minimum sidewall of 20 feet (6096 mm) below the inlet opening. Where a stratum of gravel or equally pervious material of 4 feet (1219 mm) or more in thickness is found, the sidewall need not be more than 10 feet (3048 mm) below the inlet.
