Many people have septic tanks, but few give the pumping much thought. However, septic tank pumping is something that should be done on a regular basis, obviously more often in a larger family home. However, if you have a lot of land you are able to pump your septic tank out on your own, with no smell to bother you. Two septic tanks will decompose the contents for several months, and then it will slowly release into your predetermined septic field. As the contents are decomposed already and seeped out slowly, there is no discernible smell or problem, as long as it is not too near to a water source.
