A wastewater treatment system having a tank with an aeration compartment and a clarifier compartment, an air pump affixed to a top of the tank and having an air line delivering air to the aerator of the aeration compartment. The air line extends through an interior of the tank. A control panel is also affixed to a top of the tank. The control panel is electrically connected to the air pump. A raised platform is formed on the top of the tank such that an outer periphery of the platform intersects at least at one point of the cylindrical wall. The top of the tank also has an access opening formed therein located along the periphery of the cylindrical wall diametrically opposite the platform. The air pump is affixed to the horizontal platform. A housing is attached to the platform. The housing extends over the air pump and the control panel. The housing includes a base affixed to the platform and a cover removably affixed to the base so as to extend over and around the air pump and the control panel. The control panel has an electrical supply line connected thereto which extends outwardly of the tank. A float switch, a pressure transducer and a warning light are electrically connected to the control panel.
