Septic tank cleaning is a regular maintenance process. A septic tank is a device designed to treat and filter fecal matter. Its principle involves the decomposition of solid materials at the bottom of the tank, with the water-soluble substances rising to the top and flowing out through pipes, thus preventing clogs. This allows sufficient time for the solid materials (like feces and waste) to undergo hydrolysis. A septic tank refers to a small treatment structure that separates and sedimentates domestic wastewater and undergoes anaerobic digestion of sludge.
