The verdict

SWSSD runs at 368% of its industry's injury rate - far more dangerous than the typical Sewage treatment plants or facilities workplace, earning a grade F.

SWSSD: 4.4 TCR = 368% of Sewage treatment plants or facilities BLS 1.2 · 2y Form 300A (see methodology below)

SWSSD safety composite

SWSSD scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 50%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).

SWSSD (33 employees, TCR 4.4) among 29 same-industry peers, split at the industry median of 47 employees and a TCR of 4.4

SWSSD has fewer employees than the Sewage treatment plants or facilities median and a higher injury rate than the industry's median TCR of 4.4. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
