ABSTRACT:
This application discloses a septic tank construction including an inlet baffle structure and an outlet baffle structure for reducing the turbulence in the liquid or clear zone of the septic tank. The tank has oppositely disposed arcuate end walls which bow outward. In one of the end walls is an inlet for receiving incoming raw sewage. Connected with the inlet is an inlet baffle structure for introducing the incoming sewage into the fluids in the tank with a minimum of turbulence. The inlet baffle structure comprises a generally tubular structure which is connected with the inlet and terminates in a fluid introducing flared opening disposed toward the end wall. The fluid introducing opening is oval in cross section with its major axis extending vertically. In the other end wall is an outlet for discharging treated fluids to the disposal field. An outlet baffle structure for receiving treated fluids to be discharged is connected with the outlet. The outlet baffle structure comprises a tubular structure which is connected with the outlet and which terminates in a flared fluid receiving opening disposed toward the end wall. The fluid receiving opening is oval in cross section with its minor axis extending vertically.
