Observed: scored from AI use recorded in the Anthropic Economic Index (June 2026 release), 0 of 28 tasks. Estimated: scored from the task's O*NET 30.3 work activity, 28 of 28. Importance is O*NET's 1 to 5 rating of how central the task is. Model tier is the lowest tier that can do the task under the published rubric; "No tier" marks hands-on work.

The model tier this role needs

A frontier-tier model or lower covers 97% of the role's importance-weighted task work. 97% of the work is something AI can address at some tier, and 4% is hands-on.

Efficient, standard and frontier tiers come from the JobRoute model tier reference. The recommended tier is the lowest one that covers 80% of the work AI can address. How the method works.

Questions about Water/Wastewater Engineers and AI

Will AI replace Water/Wastewater Engineers?

AI already handles 12 of the 28 tasks O*NET lists for this occupation, at a task exposure of 60 or more, and the role's importance-weighted exposure is 57 out of 100. JobRoute scores tasks, not whole jobs, so the score shows how much of the work changes rather than whether the job disappears. BLS projects employment to change by +5.0% from 2024 to 2034.

What is the AI exposure of Water/Wastewater Engineers?

57 out of 100 on JobRoute's task exposure measure, the importance-weighted average of the role's O*NET task scores. Higher means more of the work is AI-doable today. 0 of the 28 task scores are observed in the Anthropic Economic Index (June 2026 release), and the other 28 are estimated from each task's O*NET work activity.

Which Water/Wastewater Engineers tasks can AI already do?

The tasks with the highest exposure are: Conduct water quality studies to identify and characterize water pollutant sources; Provide technical support on water resource or treatment issues to government agencies; Perform hydrological analyses, using three-dimensional simulation software, to model the movement of water or forecast the dispersion of chemical pollutants in the water supply. They are three of the 12 tasks that reach 60 or more.

What AI model tier does this role need?

A frontier-tier model or lower covers 97% of the role's importance-weighted task work. JobRoute assigns each task the lowest tier that can do it under a published rubric and recommends the lowest tier that covers 80% of the work AI can address.

How many people work as Water/Wastewater Engineers, and what do they earn?

367,840 people in the United States, with a median annual wage of $100,840 (BLS Occupational Employment and Wage Statistics, May 2025). BLS Employment Projections expect a change of +5.0% from 2024 to 2034.
