A method and apparatus for remediating a failing wastewater treatment system comprising (a) a positive oxygen and ozone-generating, or ozone-generating only, pressure pump having an output, (b) a tube having a first end and a second end, the first end being attachable to the pump output, and (c) an air stone attachable to the second tube end. The pump is used to deliver oxygen and ozone, or ozone only, through the tube to the air stone. As much tube as is required is used to allow the air stone to be introduced into almost any portion of the wastewater treatment system so as to introduce air into the effluent and allow aerobic bacteria to proliferate. The apparatus of the present invention could also include a plurality of such pumps, tubes and air stones, and in many combinations.
