Trend analysis for Wastewater Enterprise
Between 2017 and 2024, Wastewater Enterprise's Total Case Rate improved from 9.5 to 6.2 recordable injuries per 100 full-time workers, a 35% decrease across 7 years of OSHA reporting.
The safest year on record was 2021, at a TCR of 5.0, while 2018 saw the highest rate, at 11.9, a spread of 6.9 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.
Summed across those 8 reporting years, Wastewater Enterprise recorded 196 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 8-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2024)
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
17 DART incidents × 200,000 ÷ 713,365 hours worked = 4.77 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping

What this grade means for you
Use this grade as a relative read on Wastewater Enterprise's reported OSHA injury record versus its Collection, treatment, and disposal of waste through a sewer system peers, not a verdict on whether any single site is safe today.
- At 649% of the Collection, treatment, and disposal of waste through a sewer system benchmark, Wastewater Enterprise reports more injuries than typical peers, ask specifically how the employer is reducing them. Know your rights
- Judge this record against the wider Collection, treatment, and disposal of waste through a sewer system sector, where injury rates vary widely, before comparing it in isolation. See the industry
- Grades reflect 2016–2024 filings; check the latest establishment record straight from OSHA, or look up a different employer. Look up another
Safety grades reflect employers' self-reported OSHA Form 300A filings from 2016 to 2024 and can lag current conditions. A grade is not a guarantee that any specific workplace is safe or unsafe today. See our methodology and disclaimer.
