Cesspools are private wastewater treatment systems that can be installed along with or as an alternative to septic tanks. Like septic tanks, they require routine maintenance that includes pumping to avoid drainage clogs, backups, and other plumbing problems. To determine a maintenance schedule for cesspools, you’ll need to understand what they are and how they function.

Understanding Cesspool Maintenance

How Cesspools Function

Cesspools hold all kinds of waste material, not just human organic waste as septic tanks do. Waste moves from a house and into a cesspool tank, where organic waste floats to the top and inorganic solids fall to the bottom. Bacteria then convert organic waste into liquid, leaving the inorganic matter to become sludge. Because these wastewater treatment systems operate differently than septic tanks, they require more frequent maintenance.

When to Have Stand-Alone Cesspools Pumped

The most significant difference between a cesspool and septic tank is that a cesspool has no outlet or drainage ability. Therefore, all of its wastewater is stored inside its structure and needs to be emptied by a professional—usually once a month depending on its size and household usage. 

When to Clean Cesspools Connected to Septic Tanks

Sometimes cesspools serve as overflow areas for septic tanks. These should be pumped every few years when the septic tank is pumped. A tanker is used to pump sludge from these wastewater treatment systems, preventing a backup of waste into your plumbing.
