The tank should be inspected for the condition of the manholes, observation pipes, cracks or leaks in the tank, baffle/filter condition and pumping if needed. Tanks that have combined sludge and scum levels over 1/3 the tank capacity shall be pumped. In most situations, the tanks are pumped regardless of the amount of solids. The pump tanks should also be inspected for proper operation of alarms, pumps, etc. The dispersal cell(s) should be visually inspected for discharge to the ground surface and verifying effluent levels if any in the observation pipes.
