Septic tanks are commonly used around the country in areas where the municipal sewage lines have not been installed yet. The septic tank plumbing system is widely regarded as one of the best self-sufficient plumbing systems for getting rid of all the wastewater in the house. In a conventional plumbing system, the dirty water is carried by the drain pipes into the municipal sewage lines, where it’s then taken to the sewage plants.
