Septic tank cleaning and pumping services are available in Mio. A septic tank is the most important component of a septic system, which is a sewage system that is in place if a large scale municipal sewage system is unavailable. The tank is connected to a wastewater inlet and an outlet to a leaching field. The solids settle down in the tank and are subjected to anaerobic degradation. This accumlation of solids means that the tank has to be regularly cleaned and the wastewater pumped out of it. This can be done in Mio by experienced professionals with machines and tools that they can use to clean up the tank. Depending on the capacity of the tank, it has to be cleaned and pumped out every few years or so.
