Abstract: A wastewater treatment system for processing borne wastewater. The treatment system having a tank with an inlet and an outlet and an access assembly residing at the top of the treatment tank. The treatment tank having an aeration chamber where oxygen is added to the wastewater to encourage bacterial breakdown of the solid waste. The treatment tank also having a clarifying chamber separated by a frusto-conical wall. The treatment tank also containing an ultraviolet disinfection system which exposes the wastewater to ultraviolet light prior to the wastewater exiting the treatment tank such that bacteria in the wastewater is neutralized prior to discharge.
