What kind of figure this source publishes
The BLS category is a relative rank, not an absolute level, and it is not a first-hand measurement: it groups an occupation's percentile ranks across several published studies into four bands. It is not an employment or wage forecast, not a probability of adoption, and it does not separate automation from augmentation.
Task-level exposure

Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

0.00/ 3· Robot exposure index
Scale, basis and source
Each physical task is graded 0–3 by the setting in which robots that have been deployed, sold or demonstrated could do it (0 none · 1 purpose-built robot settings such as a fenced machine cell or a bottling line · 2 structured facilities such as a hospital pharmacy or a container port · 3 unstructured settings such as a private home or a construction site), and the grades are averaged by share of working time
Physical tasks among this occupation's O*NET 29.3 tasks
Anthropic estimated the grades and time shares with Claude Opus 5 using web search, as of 2026.
The robot exposure index is a different measure from the AI exposure figures on this site and cannot be added to or compared with them. It does not measure actual adoption or cost, and 0 also covers occupations with no physical tasks.

None of this occupation's O*NET 29.3 tasks is classified as a physical task.

ESCO occupational vocabulary
Each entry below is matched to this occupation in the published ESCO-O*NET Crosswalk (version 1, 2022). The match types are that crosswalk's; the wording is AI Changing Work's.
- drainage engineerESCO 2142.1.3This occupation is broader
Drainage engineers design and construct drainage systems for sewers and storm water systems. They evaluate the options to design drainage systems that meet the requirements while ensuring compliance with legislation and environmental standards and policies. Drainage engineers choose the most optimal drainage system to prevent floods, control irrigation and direct sewage away from water sources.
- wastewater engineerESCO 2142.1.10This occupation is broader
Wastewater engineers design sewage systems and networks for the removal and treatment of wastewater from cities and other residential areas. They design systems which are compliant with environmental standards, and aim to minimise impact on the ecosystem and on citizens in the vicinity of the network.
- water engineerESCO 2142.1.11This occupation is broader
Water engineers research and develop methods for the provision of clean water, water treatment and flood damage prevention and reaction. They research water needs in a location and develop methods for meeting those needs, such as designing and developing projects for managing water resources such as treatment plants, pipelines, pump systems, irrigation or draining systems and other water supply systems. Water engineers also ensure proper installation of these systems on construction sites. Water engineers also maintain, repair and build structures that control water resources, such as bridges, canals and dams.
- water engineering technicianESCO 3112.1.13Overlapping, not the same
Water systems engineering technicians aid engineers in the development and implementation of water supply and water treatment systems. They monitor the operations to ensure compliance with health and safety regulations, check water quality and ensure implementation of water-related legislation.
