The purpose of this circular is to show the plan for constructing an efficient and inexpensive septic tank for the disposal of sewage from the farm home. If properly installed and furnished with proper outlet tile, this tank will need no attention whatever, except the removal of the greater part of the sludge every 5 to 10 years.
