Septic tanks are installed in rural areas or for homes where there is no access to the public sewage system. All the waste water that comes from lavatories, bathrooms, washing stations, and kitchen flows into the tank through leach fields or drain fields. After entering into the tank, this waste water will get separated from solid waste materials. All the solid waste materials will settle down at the bottom of the container forming a thick layer called sludge.
