Should this be under my septic tank lid? : HomeImprovement

I just had my septic tank drained and as I finished covering back up the concrete lid for the septic tank I found this black circular object that was not in my yard just before the guy came to drain the tank.

Is it something that should have been put under the concrete lid?
