The unpleasant nature of this job should need no explaining, but suffice it to say that sewer inspectors should expect to work in dark, damp, cramped spaces filled with rats, cockroaches, and a never-ending flood of human refuse. It is through this maze of filth that sewer inspectors crawl in efforts to find and repair cracked, clogged pipes or passageways. While the starting salary for this position is not very high ($34,960), salaries as high as $61,000 have been doled out to people who are brave enough to stick with it and become skilled.
