A component of a septic system, made up of underground pipes laid out below the surface of the ground.

primary sewage treatment

remove suspended solid waste and reduce its biochemical oxygen demand (BOD)

secondary sewage treatment

uses biological processes to catch the dissolved organic matter missed in primary treatment
