We determined equipment age or year installed, estimated useful life, general rating of <br />condition, and notation of significant deterioration/wear. The assessment included the subtasks <br />described in the following subsections. In cases where multiple similar process units exist (e.g., <br />primary clarifiers, secondary clarifiers) and one or more of the units is drained by the City at the <br />time of inspection, the drained unit(s)and inner condition of the other units based on the <br />assessment were inspected. <br />Facilities included in the condition assessment: <br />1.
