Meet Operator Danny Reyes: A Grade 3 Water Career Spotlight
A grade 3 career profile following a water treatment operator through a shift, covering daily tasks, the licensing path, and real pay and job openings figures.
Objectives
- Students will describe two daily tasks a water treatment operator performs during a shift.
- Students will sequence the steps someone takes to become a licensed water operator.
- Students will use real pay and openings figures to reason about the career's outlook.
Vocabulary
- SCADA
- The computer system operators use to watch and control a water system from a control room. It shows tank levels, pump status, and alarms in real time.
- Chlorine residual
- Chlorine residual is the small amount of chlorine still left in the water after it leaves the treatment plant. It keeps protecting the water from germs all the way to your faucet.
- Operator certification
- The official license a person earns to run a drinking water or wastewater plant. Operators study, gain work experience, and pass a state exam to become certified.
Teacher overview
Danny Reyes is a licensed water treatment operator at the fictional Fernwood Water Treatment Plant, and this profile follows one of his shifts to show what the job actually involves. It explains the steps someone takes to earn an operator's license, states real pay and job-opening figures for the career, and gives students a small, concrete example to reason about why the field keeps hiring. On-the-job licensing is one path into the water sector among several, alongside certificate programs, engineering degrees, and graduate study.
Career Profile
A shift at the plant: Danny's shift starts with a walk through the control room. Screens there show readings from every part of the plant. This system is called SCADA. Next, he walks the plant floor to check pumps and filters. He collects a water sample and tests it in the small on-site lab. He checks the chlorine residual. This is the small, safe amount of chlorine left in the water. It must stay in the safe range before the water leaves for people's homes. If a reading looks off, Danny fixes it right away. Then he writes it down in the plant's logbook.
Becoming licensed: Danny started with a high school diploma. He was hired as an operator-in-training at Fernwood. He learned the plant by working next to a licensed operator. In every state, an operator must pass a test. Passing it earns an operator certification. Licenses come in levels. Many states call them Class I through Class IV. The level depends on two things. One is how big the plant is. The other is how much experience the operator has. A small town's plant might be run by a Class I or II operator. A large city's plant needs someone with a Class III or IV license.
Pay and outlook: In 2025, water and wastewater treatment operators earned a median pay of $60,020 per year. That figure covers the whole country. Median means the middle amount, so half of them earned more and half earned less. The Bureau of Labor Statistics keeps track of jobs like this one. It expects about 10,000 new operator openings in the country each year through 2035. All of those openings are expected to come from retirements and career changes, not from new plants being built. About one out of every three water workers today will be old enough to retire in the next ten years. That is a big reason why the field keeps looking for new workers.
Student Handout
Discussion questions:
Name two specific tasks Danny does during his shift at the Fernwood plant.
Put these four steps in order. Here they are, mixed up: passes a state certification test, is hired as an operator-in-training, earns a high school diploma, learns the plant on the job.
Suppose a small plant has 9 operators. About one out of every three water workers in the country will be old enough to retire soon. About how many of that plant's 9 operators might retire soon? Show your division.
The profile says the water field has about 10,000 new operator openings every year. Why are there so many openings, even though not every plant is growing bigger?

Answer Key
Answer: Any two of: checking control-room (SCADA) readings, inspecting pumps and filters, collecting a water sample, testing the chlorine residual in the lab, or writing readings in the plant's logbook.
Answer: Earns a high school diploma → is hired as an operator-in-training → learns the plant on the job → passes a state certification test.
Answer: 3 operators. 9 ÷ 3 = 3, since one out of every three of the plant's 9 operators represents 3 operators total.
Answer: Because many of today's operators are getting older and many will be able to retire soon, and others change careers, plants need to hire and train new operators to replace them, even in years when the number or size of plants is not growing.
Differentiation
Support (below grade level)
Provide a simple sequence graphic of the licensing path (High school diploma → Operator-in-training → Learn the job → Pass state test → Licensed operator) alongside the Career Profile text, and let discussion question 3 be solved using counters or a simple drawing of 9 circles split into three equal groups.
Extension (above grade level)
Ask students to figure out how many operators might retire soon at a larger fictional plant with 15 operators, using the same one-out-of-three idea, and to explain how they solved it.
ELL supports
Pre-teach SCADA, chlorine residual, and license with simple definitions and, if possible, a labeled photo or drawing of a plant control room. Allow discussion questions 1 and 2 to be answered with short phrases or by pointing to a picture sequence rather than full sentences.
