How to Recruit Water and Wastewater Operators: Hire for the License Path, Not Just the License

To recruit water and wastewater operators, recruit for two pools at once: licensed operators who already hold your state's grade, and trainees you certify on the job, which BLS says is how entry-level operators often complete licensing. Put pay by license grade, the shift rotation and paid exam fees in the first lines of the ad, keep the first step to a short mobile form, and call back within a day before walking candidates through any civil service application.

Who you are actually recruiting

BLS counts water and wastewater treatment plant and system operators as one occupation (SOC 51-8031). In the BLS Employment Projections 2025-35 there were 131,000 of them in 2025, projected to fall to 123,500 by 2035, a change of -5.7 percent. BLS still expects about 10,000 openings a year, mostly to replace operators who retire or leave the occupation. The median annual wage was $60,020 in May 2025. The typical entry requirement is a high school diploma or equivalent with long-term on-the-job training.

That combination is the recruiting problem in one line: a shrinking occupation that still has to replace its people, where the credential takes time to earn. If you only advertise to licensed operators, you are competing with every neighboring utility for a small group. If you also recruit people you can train, the pool gets much larger.

The license, stated accurately

On the drinking water side, the 1996 Safe Drinking Water Act amendments directed EPA to develop operator certification guidance, and EPA's 1999 final guidelines cover operators of community and nontransient noncommunity public water systems. States implement them through their own certification programs, and EPA withholds 20 percent of a state's Drinking Water State Revolving Fund capitalization grant if the state has no program (EPA, About Operator Certification). Wastewater certification is set by each state. BLS says operators "typically require a state license; however, entry-level workers often complete their licensing requirements during on-the-job training," and that operators moving between states may need to take new exams. Grades, exam eligibility and trainee rules vary by state, so check your state program before you write the requirement.

Where to find water and wastewater operators

• Your own maintenance and distribution crews. Meter readers, distribution workers and plant maintenance staff already know the system. A posted path from their job to operator-in-training is the cheapest recruiting you will do.
• Registered apprenticeship. The National Rural Water Association runs an apprenticeship recognized by the U.S. Department of Labor for water operations and wastewater operations occupations, an approximate two-year program of classroom instruction and on-the-job training delivered through state rural water associations (NRWA). Its applicants must be at least 18, hold a high school diploma or GED and a valid driver's license. Our apprenticeship recruiting guide covers building that track.
• Veterans. A soldier in the Army's 92W water treatment job (MOS 92W) installs and supervises water purification equipment and performs water quality tests (GoArmy). That is not a state license, but it is directly relevant experience. See hiring veterans for the federal programs.
• Adjacent plant and field workers. Maintenance technicians, lab technicians, pool and spa service techs, and industrial process operators already work with pumps, chemicals and control screens.
• Local people who have never considered the job. Most adults do not know treatment plants hire trainees. Facebook and Instagram ads reach them where they already scroll, which a job board cannot do because they are not searching for the title.

What to pay water and wastewater operators

Start from the BLS May 2025 median of $60,020 a year, then publish your own scale by license grade. The water and wastewater operator job description has the full wage section, including the percentile spread and the median by employer type. Two lines move applications more than the number itself: the raise each certification grade earns, and who pays the exam fees and study time.

How to write the ad

The job description is the civil service document. The ad has to stop someone scrolling after a shift at a warehouse or a garage. Lead with what an operator checks first: pay, the rotation, and the license path.

• Say the shift pattern honestly. BLS notes plants run 24 hours a day, 7 days a week, and rotating shifts including nights and weekends are common. Name yours and the on-call expectation.
• State the license requirement exactly: water or wastewater, the grade, and whether trainees can apply.
• Name the benefits a public utility can offer that private employers struggle to match, if you have them: pension, schedule stability, paid training.
• Write for everyone in your service area. Meta employment ads run in a special ad category with no targeting by age, gender or ZIP code and a minimum 15-mile radius.

More on structure is in job ad copywriting.

Screening questions for a mobile application

Keep knockouts to the things the job truly requires. Everything else belongs on the phone call.

• Can you work rotating shifts, including nights, weekends and on-call? (knockout if the role requires it)
• Do you hold a valid driver's license? (knockout only if operators drive to lift stations or remote sites)
• Do you currently hold a water or wastewater operator certification? If so, which state and grade? (sorting question, not a knockout, if you hire trainees)
• Are you willing to study for and sit the state certification exam within the time we set? (knockout for trainee roles)

If a formal civil service application is mandatory, collect interest first with a short form, then call and walk the candidate through the formal application. Long public-sector applications are where most applicants are lost.

What it costs to reach operators on social

Boostpoint's 2026 Social Job Advertising Benchmark has no utilities role family, so we do not quote a role-specific figure for operators. Across all 891 Boostpoint-managed campaigns on Meta, the median campaign cost $13.88 per applicant and the middle half ran $6.48 to $29.74. The bigger lever is the apply experience, which explains 70 percent of cost variation between campaigns: campaigns with apply rates under 5 percent paid $53.77 per applicant, while those at 20 to 35 percent paid $4.41. Cost per applicant is not cost per hire. See the full benchmark.
