Disposal services empty septic tanks using a Sludge pump. This pump is used to remove and process liquid that contains a high amount of solids. They work similarly to mud pumps or other types waste water pumps. These pumps are designed to removing all kinds of substances and bacteria that otherwise turn into gases that can fill and pollute the air, making it toxic.
Sludge pumps are used for septic tank emptying, in mining, horticulture, and any other overwhelming waste liquids that need to be removed from a certain area or septic system in order to keep people and workers safe.
