1. A waste water treatment system for further treating waste water effluent from a primary treatment system, comprising:

  • a system controller means to control the operation of the treatment system,a dosing tank means for accepting the effluent and providing a downstream flow of effluent,means for pressurizing fluid flow downstream from the dosing tank means and throughout the treatment system,the dosing tank means having at least one float switch within the dosing tank means connected to the system controller means to activate the means for pressurizing fluid flow downstream from the dosing tank means,means for filtering waste material from the downstream flow of effluent,the means for pressurizing fluid flow comprising a pump connected in-line between the dosing tank means and the filtering means,backflush pressure means for accepting filtered effluent from the filtering means to subsequently backflush the filtering means at intervals of time, wherein the backflush pressure means comprises a hydropneumatic tank to store filtered effluent until the system controller means causes the stored filtered effluent to flow from the hydropneumatic tank back through the filtering means to thereby remove filtered waste from the filtering means,wherein the filtering means comprises a filter in-line between the pump and the hydropneumatic tank,a plurality of fluid flow tubes to accept the filtered effluent, the tubes having emitting means and discharge means to effect the discharge of the filtered effluent into a ground environment comprising field flush valve means downstream from the means to discharge the filtered effluent through the emitting means, the system controller means providing a signal at selected intervals to operate the pump and to open the field flush valve means thereby creating a forceful turbulent fluid flow through the fluid flow tubes effecting a cleaning of the emitting means and subsequently causing the filtered effluent to flow into the primary treatment system for reprocessing.
