Career change, or post-retirement job?

[MILSPEC]

I'm curious on what the professionals in the septic industry think of someone going into septic tank pumping as a career. (With my present job, I'm earning 65k w/ great benefits and only 8.5 years to go before I can retire.) I will be almost 55 when I do retire, and would like to continue working, but in a different industry. I was considering pumping as that, "post-retirement" job to give me something to do with added income.

I have a CDL w/ tank and hazmat endorsements.

Is this a good career choice after I retire from what I'm doing now?

Thanks in advance for your thoughts.
