You mean the septic tank has no (round?) hatches for pumping and the pump man has to lift off an entire section of the top leaving say a 3x4 foot opening?
If the existing concrete covers are not steel reinforced, cutting a (15" round? 12x18" rectangular?) hatch could make them too weak to bridge the width of the tank.
So you may need to have replacement lid sections (steel?) fabricated with access hatch, riser if desired, and hatch cover. Looks to me that a 3x4 foot steel section would need upturned edges and/or ribs stamped into it for rigidity.

How to restore power more quickly: Electric company does a hasty job and quickly moves on to the next job site, and, after hooking up individual affected homes, comes back to finish/dress things up. (2) Massachusetts eliminates the requirement for a police detail at the job site.
