Without a septic tank, a household septic system is incomplete. A container made of fiber, plastic, or concrete that is watertight. Septic tanks collect sewage and wastewater from homes that are not connected to a public sewer system. As a result, septic tanks must be emptied every three to five years to be maintained. Also, how much you use it and how many people live in your house have an impact. A septic tank will function properly if it is regularly maintained.
