The wastewater treatment system includes a hollow, elongate, horizontally disposed, cylindrical body made from plastic is adapted for water storage and treatment. The cylindrical body includes reinforcement ribs formed by a helically wound steel band embedded in the plastic and extending between opposite open ends of the elongate cylindrical body. A voltage source selectively energizes the steel band. A pair of bulkhead members respectively extends across and covers opposite ends of the cylindrical body. A fluid-tight wall is mounted in the cylindrical body, the first bulkhead member, the fluid-tight wall and the cylindrical body forming a fluid-tight tank defining a liquid storage chamber. The second bulkhead member and the fluid-tight wall define a dry liquid treatment equipment chamber. An inlet pipe extends into the tank for admitting the pretreatment liquid into the tank. An outlet pipe extends from the tank and discharges the treated liquid from the tank.
