Talk about a time you have shown great pride in your work. Do you think you can bring this same sense of pride to the water treatment operator position?

"I was taught from a young age to do things with passion and pride and I'm happy to say that I've brought this same sense to my career. In my current role, my work product, being on time, and accurate with my work has a great impact on a large number of customers and I give it my all. Hearing a customer say thank you always lets me know my hard work was worth it. As a water treatment operator with your team, I would never lose sight of the people that would be drinking and using city water, and taking pride in what I would be doing here would be something I never take lightly."

If you take a step back and look at the greater picture of what a water treatment operator does and who their work impacts, you will be providing a very valuable service to the population impacted by the water treatment plant you are interviewing with. Your interviewer wants to hear that you take pride in the job to always ensure you work for the greater role and they hope to hear about a time you've worked with great pride in the past.

Answer this in a heartfelt manner as you discuss a time you've shown pride in your previous work. As you think about this prior to your interview, pride comes from knowing who your work impacts, helping others, continually progressing, and making a bigger difference in what you do. No matter what example you give, be sure to show excitement for having pride as a water treatment operator.

When a change occurs in the workplace, how do you naturally adjust with ease?

"Having worked in water treatment operations for the last 11 years, the one thing that has been true is that change is inevitable. Because I am someone who is enamored with technology and how it helps improve processes and life in general, I've always embraced new equipment and processes with ease. For me, success in handling change comes down to having the right attitude and a dedication to learning new things. Perhaps the best example of this was when the plant I am with currently installed a SCADA unit. Some older operators were thrown for a major loop, but I quickly looked to the fact that a lot of necessary night and weekend shifts were going to go away and that was exciting for work-life balance. I led the charge in the training under the new system and was recognized for helping my team charge forward."

Water treatment facilities have always adapted to the modernization of technologies and there is no sign that these advancements will stop. It will be important for your interviewer to hire a water treatment operator that is fluid to changes in their environment, so they need to hear how you have done this in the past during your career.

Prior to your water treatment operator interview, be sure to think of some times you have had to adapt and be fluid in your work due to rapid changes. The important things to reflect on are your ability to remain positive in any situation out of your control and your willingness to learn new ways of doing things. As you talk about one or two of the big changes you have faced during your career in the past, make it very clear that you would enter this role as an employee who is always open to change.

What do you feel is your greatest weakness you would bring as a water treatment operator?

"As someone looking to break into this field as a water treatment operator, my obvious weakness is lacking direct experience with the machines and systems I would be operating each and every day. I want you to know that I'm very competent and comfortable learning new software and maintenance programs and have proven my ability to do this over the last five years in my current job. If I'm fortunate enough to be offered this position, I will come astutely focused on learning the equipment I will be using and ask as many questions as possible to ensure I'm up and running in short order."

As someone who has a vast amount of experience in water treatment operations, your interviewer knows that any candidate they consider will come with some sort of weakness. They're giving you the chance to be honest with them about what you feel that weakness is. Additionally, they're hoping to hear that you are cognizant of this weakness and that you are willing to work hard to overcome it.

It is important to answer this question honestly but also keep the answer positive. Talk less about the weakness you feel you have and more about what you will do to improve on the weakness if hired as their next water treatment operator.

What do you consider to be your greatest strength and how do you feel it will help you as a water treatment operator?

"I feel that my greatest strength is my work ethic and it's been a strength that I've demonstrated from a young age working in a mechanic shop through high school. It has always been ingrained in me that I need to give 100% to my employer every moment I am on the job. This dedication has helped me as a water treatment operator because this job is demanding, requires attention to detail, and requires me to be a safe worker. A strong work ethic keeps me and my team safe and helps to ensure high-quality water leaves my facility."

No matter how you answer, be sure to give an example of a time you were recognized for displaying this strength.

Talk about a time when your communication skills greatly benefited a team effort.

"As you can see from my resume, I'm an active volunteer firefighter and communication is something that is always stressed in this field. This is especially necessary on the scene of an active fire or an accident. Last year, we were working a brush fire in conditions that were less than ideal. There were extremely high winds and our main goal was to keep the fire away from a few homes in the area. Our chief took the lead in giving orders to the team onsite and I listened and got to work. As I noticed my end getting more out of control with the wind, I didn't hesitate to get on the radio to request more help and it came quickly. I knew that controlling the far end toward the homes was vital and we were able to redirect the burning with three more men. I'm confident that the communication skills I've developed in this role will aid me in this job as a water treatment operator."

Water treatment operators communicate important information and data with their colleagues and stakeholders. To ensure that you would join their operation as a solid communicator, your interviewer wants to hear you thoroughly discuss a time when your communication was essential in a successful team effort.

You likely can think of several different times when you used communication on the job when a team performed well. Your interviewer won't be focused on the total makeup of the team you are discussing or even what the task was. What's important here is highlighting your ability to be open with your colleagues, your prioritization of communicating things clearly, and your ability to listen and take direction when needed. If possible, make sure the scenario you discuss highlights your ability to do all of these things.

In this job, you will be handling hazardous chemicals like ammonia and chlorine. Would you be comfortable with this aspect of the job?

"Yes, I would be very comfortable with this aspect of being a water treatment operator. In my current job, our manufacturing process includes the use of zinc and cadmium and I've had extensive training in the handling of those. The use of personal protective equipment is vital in my job, and I wear protective eyewear and gloves at all times they are required and never let this slip. The safety of my colleagues and myself is always at the front of my mind and will continue to be if I join your team."

In the treatment of water for public consumption, there are several hazardous chemicals that are used in the processes that you will be handling as a water treatment operator. Your interviewer needs to be assured that you will join their team as someone who is confident in their ability to work with these materials in a safe fashion.

There are a few points that you want to make as you answer this question. First, to directly answer their question, let your interviewer know that you are comfortable with this aspect of the job. To do this, talk about any positions you've held in the past where you worked closely with hazardous materials. Discuss your role and any formal training you had. The other piece you want to reiterate is the importance of wearing PPE in handling chemicals and how you would always prioritize this on the job as a water treatment operator.

Talk about the math skills you would bring to this role as a water treatment operator. How have you applied math in any previous jobs?

"I would come to your plant as a water treatment operator with very solid math skills. During high school, I successfully passed levels through Calculus One and have a great understanding of the calculations needed to quickly convert volumes and calculate area measurements. In my current job, my daily logs include some basic math calculations and utilizing data. My work has always been error-free and I take great pride in that fact."

As a water treatment operator, it is important to know that basic math skills in calculating area, flow rates, and simple volume conversions will be a vital part of the job. Since accuracy will be key, your interviewer needs to hear that you would come to their team with solid math skills. They're also hoping to hear that you have applied math principles in some capacity in your prior work.

You can answer this question briefly and if you recall, cite your math grades during your education. If you've taken advanced math courses, discuss this as well. Then be sure to reiterate you know simple math concepts will be a part of the work of a water treatment operator and touch on any math you've had to calculate in any previous roles that you've held.

How important is safety to you in your work? What types of safety measures did you practice in your last job?

"Safety has always been a focus and primary concern for me on any job site. Early in my career, I worked in construction and made sure that safety surrounding ladders and equipment was always adhered to. I've been formally trained in protective safety equipment and have taken several haz mat trainings. Water treatment plants see too many accidents with over 60 deaths in the industry in the last 10 years. I know I will be working with heavy equipment and hazardous chemicals in this role and will always take the training and safety protocols seriously."

A water treatment plant is riddled with safety hazards. These hazards include hazardous chemicals, dangerous machines, heights, and heavy lifting. Your interviewer needs to be assured that you will come to this job as a person who is focused on safety at all times on the job. To do this, they'll look to hear you talk about the safety protocols you've had to adhere to throughout your career.

Safety is incredibly important as a water treatment operator and your interviewer would like you to demonstrate that through your answer. Start by discussing any safety-related training you have attended throughout your career and then discuss the tasks in your current role that require a focus on safety. Last, make sure to let them know you are aware of the safety hazards you will face in this role and let your interviewer know that you will always remain focused on doing things properly on the job.

"To me, safety is the primary concern on the job site. In previous jobs, it was essential to know and inspect the area we were going to work for that day, look for any hazardous areas or objects also know what crafts were going to be nearby. We also made sure each team member knew what their responsibilities were, and they felt safe doing it."

Working as a water treatment operator comes with some physical demands. Do you think you are able to handle the physical requirements in this line of work?

"I am a person that likes to be on their feet all day and I can really see myself thriving in this role as a water treatment operator. In my current job, I am required to lift boxes that can weigh as much as 85 pounds and do so with ease. I also operate a large hand-powered lifting jack to move pallets around and am able to do so without any problems. When I applied for this role, I made sure to read all of the physical requirements of the job and am confident in my ability to perform them on a daily basis."

Working as a water treatment coordinator will require you at times to lift heavy materials, climb ladders, step into confined spaces, and undertake other strenuous physical activities. If they are going to seriously consider you for the job, your interviewer needs to hear that you are aware of these physical demands and that you can handle all of the tasks with ease.

Before interviewing or even applying for a job as a water treatment operator, it is important for you to know all the physical requirements of the job. They can typically be found right in the job description. As you answer this question, reiterate to your interviewer that you are aware of and can meet the physical demands of the job. If possible, give examples from prior work where you've worked under similar conditions.

How detail oriented are you in your work and why will this be vital in a water treatment operator position?

"As an experienced water treatment operator, I have worked under specific regulatory standards that were required to be adhered to at all times. I was recently recognized by my supervisor for so closely abiding by the guidelines of the Clean Water Act and Safe Drinking Water Act. Because the list of contaminants regulated by these statutes is ever-changing, I must pay attention to what is happening in the industry and will continue to do so in this role."

The water treatment processes and equipment you will be operating on a daily basis will require keen attention to detail. To ensure that you will prioritize this on the job, your interviewer needs to hear you clearly discuss the details of any prior job where attention to detail was vital to success.

Prior to your water treatment operator interview, be sure to put some thought into a job duty you've had in the past where you needed to focus on details in your work. Outline your role in ensuring that every detail was considered and why it was important to do so. Then, to seal your answer, make sure you express that you understand which duties of the position you are interviewing for will require this same attention to detail.

"Being an electrical apprentice takes a high level of attention to detail, do to job site safety being the top priority and on a personal level because I take pride in my job, and it reflects on me."

How can we ensure that you will take the tasks of record keeping and work logs seriously as our next water treatment operator?

"As you can see from my resume, I've spent a portion of my career driving commercially and maintaining both product records and driving logs were vital in this role. My philosophy was to record things as they happen to eliminate any risk of forgetting things down the road. This led to a stellar record of documentation throughout my time driving. I know that water treatment operations involve a lot of tasks that need to be logged and work documented. These are tasks that I will always take seriously."

Local, state, and federal governing bodies require proper documentation of water treatment and operators are on the frontline for ensuring that record logs are consistently up to date. If you emerge as their top candidate, your interviewer needs to have the sense that you will take these administrative tasks seriously at all times on the job.

"First and foremost, I'm confident that you won't be interviewing a more dedicated and hardworking individual than me. I've proven throughout my young career that I'm always able to show up to work and give my all, and I know this is a vital trait you are looking for in your next water treatment operator. I would also bring a proven track record of accuracy and care in my work and will be proud to do so in this role as well."

According to the US Bureau of Labor Statistics, the job outlook for water treatment operators is expected to decline. Knowing this, your interviewer will likely be looking for a great pool of candidates who apply and make it to the interview stage. In posing a question like this, your interviewer is giving you the opportunity to give your best sales pitch on why you should be the candidate that gets offered the job.

Now is the time for you to highlight the knowledge, skills, and abilities you would bring that make you the perfect match for the job. Prior to your interview, be sure to thoroughly look over the position description and come prepared to outline where you'll be able to hit the ground running and exceed.

What interests you in working for a public entity in a water treatment facility?

"I'm really looking forward to the opportunity to give back to the community where I was born and raised and where I am now raising my own family. Knowing people who work for the city currently, I see the great pride they take in their respective jobs, and am looking to do the same as your next water treatment operator. Of course, the amazing benefits package and state retirement plan are certainly appealing as well."

A majority of water treatment operators work in treatment facilities run by local cities. Joining the workforce in the public sector is a unique and exciting opportunity and your interviewer wants to hear that coming aboard in that type of atmosphere is appealing to you.

If asked a question like this, it's important to keep in mind that your interviewer is looking for you to think bigger picture and beyond the actual role of a water treatment operator. Prior to your interview, and hopefully, even prior to applying, you want to ensure that working for a public entity is appealing to you. There are many ways you can take your answer, from the great benefits provided to the ability for your work to impact a large population of people. No matter how you answer, make sure your interviewer walks away from your time together knowing that you are committed to the overall mission of working for a public agency.

Why are you passionate about a career in water treatment operations?

"Over the course of my career, I've proven myself to be a confident and competent employee who always gives 100% on the job. I have all the confidence in the world that I can step in as your next water treatment operator and have the duties mastered in short order. What's important to me at this point in my career is giving back to something bigger and working in a role that positively impacts lives, and I'm confident I found that in this opportunity from what I've learned from you today."

The time commitment, focus, and hard work of a successful water treatment coordinator requires a distinct focus and dedication. To know that you will bring dedication to this work, they want to hear that you are passionate about the work and/or the overall mission of the treatment facility you are interviewing with.

This is a great time to tell a personal story about what inspired you to pursue a career in water treatment. By tying the work you will be performing to your own values, you'll surely win over your interviewer with this answer. You can also talk about what aspects of the job will continue to motivate you for the rest of your career in this role.

"Every human in the world requires clean water to drink and use, and working in the water treatment industry allows me to produce this water. This alone, in my opinion, is one of the most meaningful careers a person can choose."

Our treatment plan operates 24 hours a day, seven day a week. What is your overall availability to work and ability to be on call?

"I am fully aware of the hours requirement for this role as a water treatment operator and am able to commit to day, evening, night, weekend, and holiday hours. In my personal time, we have a very busy family with kids' activities. Fortunately, my wife works a day shift job on the weekdays and we have solid backup plans for child care with close family nearby. One thing I'm hoping to understand is how scheduling works. Are you able to shed more light on the shifts I would be working if I'm offered the position?"

Water treatment processes occur 24 hours a day, seven days a week, and 365 days per year. On top of this, the scheduling of shifts can vary greatly and can include 12-hour shifts, seven work days in a row, and other various shifts. Your interviewer wants to hear your overall availability to work varying shifts and hours, along with your ability to be on call if it is a requirement for the job.

If the water treatment operator position calls out the specific hours for the job in the job posting, that is great! Make sure to reiterate that you will be able to meet the requirements. But a lot of time, the hours for the job will be more generic. If this is the case, be sure to give an overview of your availability while remaining open to any scheduling that would come your way. To be fair to yourself, you should also be open and honest about any scheduling conflicts that you may have with your family and your personal life. In the end, your interviewer knows that every individual will have their own unique personal commitments, and being honest about them up front is the best.

Tell me about yourself and the type of person we would be getting as our next water treatment operator.

Her family is from this area, where she was raised, and we are excited about the opportunity to come here. Outside of work, I am an avid outdoor enthusiast. I spend as much time in the woods as possible, both hunting and trapping, and am excited about those opportunities here. I also love to cook and grill, with smoking meat being a new hobby I picked up in the last few years. I'd be more than happy to answer any questions you may have for me throughout the interview."

While a majority of your interview will focus on the skills and abilities you will bring as a water treatment operator, getting to know you a bit as a person will help gauge how you will fit in with the team. Your interviewer will surely give you the opportunity to talk about who you are as a person to give them a chance to get to know you better and how you will fit into the culture and team you will be joining.

A great way to frame your response here is to talk about the past, present, and then the future in regard to who you are and who you aspire to be in the future. This is the chance for your interviewer to get to know you as a person, so make sure to discuss your family, your hobbies, and your internal motivators to be the best you can be. Finding common ground is important for your interview, so don't hesitate to open up about yourself.

As our next water treatment operator, will you be willing to take additional coursework and trainings that will be required over time?

"Yes, if I'm fortunate enough to join as a water treatment operator, I will always be open to learning and would certainly be willing to expand my knowledge in this industry. With my current company, I've had many opportunities to participate in continuing education credits and have loved taking them. Over the last couple of years, I've taken courses in advanced machine operating and diesel mechanics. With those, my duties have certainly increased and given me opportunities to be promoted."

Do you currently have a water operator certification? If not, are you willing to obtain certification if hired?

"No, I do not currently hold any water operator certification as I'm looking to break into the field. If I'm hired for this position, I would prioritize studying for and passing the state's required written examination for certification. Can you expand upon any support that is provided to new hires that aren't yet certified?"

Depending on the water treatment operator position you are interviewing for, carrying or obtaining the proper state certification may be either preferred or required for the job. Your interviewer needs to know if you are currently certified and if not, that you are willing to do so upon being hired.

Prior to even applying for the water treatment operator position, you would have seen a certification as preferred or required for the job. If you do hold any certification from a state you are currently applying in, answer with an emphatic yes!

"I do not have any operator certification, but I'm always open to learning more to be up to your standards."

Have you ever received any on-the-job training that will benefit you in our water treatment operator role?

"Throughout my career to this point, I've been open to training and learning new skills on the job that have helped me improve.

"As you can see from my resume, I've spent the last six years out of high school as a machine operator with a large manufacturing facility. While I didn't have a formal leadership title, I am now seen as a go-to among my team for training new staff. I love working with new hires to train them well and bring them up to speed quickly so they can become fully functioning members of the team as soon as possible. Once I'm fully trained and up and running in this role as a water treatment operator, I would have no issue taking the lead on the job when necessary."

If you don't, they'd love to hear that you will relish this opportunity when given the chance to take the reins and lead.

How you answer this could determine whether the interviewer views you as a leader and/or as someone capable of doing so with the correct training. If you do have leadership experience in your career, talk about the team that you were in charge of and the leadership duties you undertook. If you don't have direct work experience in a formal leadership position, that is okay. Just be sure to reiterate that you would feel comfortable and competent in leading any important efforts in the proper treatment of water in this role.

"I have not been given an official leadership opportunity. Still, I always work towards improving my career; I look to improve on my skills to know what is necessary to be an experienced and knowledgeable leader."

What do you know about our treatment plant?

"As a water treatment operator, I always want to ensure that I am working with a premium facility that takes great care in its reputation. After researching your treatment plant, I discovered that you took great pride in your work and that your employees are frequently recognized and awarded for good work. I'm also very excited about the opportunity to move close to our families and get back home to this area. Working for the city of Springfield would be an honor for me."

Water treatment plants can differ greatly in the amount of water they treat on an annual basis and the greater population they serve. Technical operations can vary as well. Your interviewer wants to hear that you've done your homework on the plant you are interviewing to join and see it as a great fit for you.

Prior to your interview, be sure to do as much research on the plant as possible. Some things to focus on are the size of the team you'll be joining and the total area that the plant serves. Be sure to practice your answer as the likelihood that you will be asked this question is high. Because most water treatment facilities are operated by local governments, make sure to highlight your excitement to join that atmosphere.

Why do you believe water treatment plants are important?

"Water is the most basic human need and resource for promising life to everything on the planet. Today, water pollution and water scarcity are two major issues facing the population of the world, and ensuring that water is properly treated and disinfected is vital to sustaining a future. I want you to know that this is a job I would take great honor and pride in, knowing that my family, my neighbors, and my friends will have access to safe and healthy drinking water."

While it can seem like a thankless and unappreciated job at times, the work of a water treatment operator and the plant plays a major role in safe and clean consumable water for the population they serve. Your interviewer needs to be assured that you understand the importance of this service, so they pose this question during your interview.

This is a great time to brush up on the history of water treatment and learn its importance prior to your interview. As you do this, you'll learn that the first municipal water treatment plan was in Scotland in the early 1800's and that water pipes for carrying water came shortly after. Make sure you reiterate the importance of disinfecting consumable water for the public and the fact that water quality can greatly differ by region.

Talk about your most difficult experience in your current job. How did you work hard to overcome that situation?

"As you can see from my resume, I've worked for a county highway department for the past six years. The difficult times come every year during winter storm season when we have a limited crew and roads need to be made safe. Most notable was a storm a few years ago where over two feet of snow was dumped in a 24-hour period. The first priority was preparation and watching weather reports. Knowing that the storm was coming, I prepared ahead by catching up on as much sleep as possible to make a full 24-hour shift. From there, once the storm was progressing, success was found in having a plan of attack and communicating with my team throughout the evening, night, and next day as we made the country roads and highways as drivable and safe as possible."

Water treatment operators can face some very difficult challenges on the job, ranging the spectrum from things like equipment breakdowns to major contaminations. If they are to seriously consider you for the job, your interviewer needs to be assured that you would come to their team with the ability to resolve issues in a calm, cool, and collected manner.

Since they specifically ask, you want to ensure that you answer this question using a specific example of a recent challenge that you faced on the job. Carefully walk the interviewer through the situation you faced and the steps you took to handle it. Make sure to highlight the positive outcome that came from the situation because of your hard work. Also, don't hesitate to talk about the resources and teamwork you used in this effort because that will be important in this job as a water treatment operator.

How will you motivate yourself to keep going as a water treatment operator, even when the hours get long?

"If I'm fortunate enough to be hired as your next water treatment operator, motivation on the job will never be an issue as I like to stay busy by nature and always like to be doing something. I completely understand that there will always be work to be done, even when the essential tasks are completed. If I ever experienced downtime, I wouldn't hesitate to pick up a broom or mop to ensure that the floors were clean. I'm also very experienced with maintaining equipment and I could be relied on to perform any routine maintenance needed."

Your interviewer is well aware that long hours and oftentimes working solo require their water treatment operators to have internal motivation and drive. Your interviewer needs to be assured that you will join their facility with the ability to stay on task and upbeat, even when the required hours and tasks can seem to drag on.

You want to really put thought into a question like this prior to your water treatment operator interview. Knowing that there will be downtime on the job, your interviewer wants to hear that you will keep busy with cleaning tasks, administrative duties, and even extra work like instrument calibration. What they don't want to hear is that you'll spend time playing on your phone or taking care of personal business. If possible, try to talk about prior roles you've held where you were able to stay motivated and busy at all times.

Can you name two or three different types of water pumps?

"I have direct hands-on experience with submersible pumps used around the home and rotary displacement pumps used in hydraulic systems. Having a strong background in mechanics, I would come to your team as a water treatment operator who is excited to learn the ins and outs of the positive displacement pumps you use here. Can you elaborate on any other types of pumps that this facility uses the most?"

In-plant pump stations are a key component of any water treatment facility, giving the ability to move large quantities of water in a quick fashion. Your interview asks this question in hopes that you have some familiarity with the different types of water pumps that are used in the water treatment process.

This is a question that you can certainly answer briefly and factually. Take a moment to explain which water pumps you are most experienced in working with if you have firsthand experience. If you need to, be sure to familiarize yourself with the centrifugal, progressive cavity, and positive displacement water pumps, as they are the most commonly used in water treatment processes. If you want, you can follow up with a question for the interviewer on this subject as well.

"I only know of two basic types of water pumps: centrifugal and positive displacement. Both models are designed to move water from one place to another continuously."

Are you familiar with the use of ozone in the water treatment process?

"I'm very familiar with the use of ozone for preserving food products and know it's been highly effective in that usage. I'm also familiar with the fact that it's been effectively used in fire and flood restoration efforts for decades. I honestly don't know much about the actual process for the use of ozone in water treatment, but would love to learn more. Is this something you are considering implementing at some point in the future?"

The use of ozone in the treatment of water has historically been used in the private industrial wastewater setting. Public water treatment is slowly catching on, but it is expensive to implement. If the position you are interviewing for is currently using ozone treatment, or if they might be thinking of doing it in the future, your interviewer will be looking to hear that you are familiar with the basic fundamentals of its use.

Ozone is used in many realms to remove harmful chemicals and materials, from fire restoration to being used as a preservative in the food & beverage industries. Whether you are familiar with its usage in water treatment firsthand, make it clear that you understand its use in removing pollutants and other contaminants from water. This question may provide a great opportunity for further discussion if you ask questions at the end of your answer.

Are you familiar with the two common processes for separating water and floc?

"Yes, I sure am! After coagulants are introduced to separate the solids from the water, first comes sedimentation and this allows the flocs to sink to the bottom for removal. Then comes filtration, where water is passed through a system to pull all remaining solids out of the water."

After coagulants are added to a large batch of water and are treated, there are two steps that occur to ensure that the floc is removed from the water. Your interviewer needs to hear that you are familiar with the sedimentation and filtration process as part of the process you will be working on within this role as a water treatment operator.

Emphatically tell your interviewer that you are aware of the sedimentation and filtration processes that separate the solids from water prior to the final disinfection. You should answer a question like this factually and as briefly as possible.

What are coagulant chemicals used for?

"I understand that coagulation treatment is vital in the treatment of water to help pull solids out of the water prior to the final filtration of it for usage. In an operation like yours, it sounds vital to pull out things like sand, clay, bacteria, and algae that may be present. I'm familiar with coagulants like aluminum sulfate and ferric chloride. Can you talk a bit about the coagulants you use here?"

In the treatment of municipal water, chemicals like aluminum sulfite and ferric chloride are used to help remove suspended solids from water. Your interviewer is looking to hear that you are familiar with the usage of these coagulants and what the goal of their use is with this question.

As you fully research the water treatment processes that are used for public consumption, you'll find out that coagulation treatment is a very common step in the overall process that happens prior to sedimentation and filtration. The goal of the coagulation chemicals is to cause solids in the water to clump together and sink to the bottom for easier filtration. As you prepare to answer a question like this during your interview, be sure to touch on your familiarity of the different coagulants used in the treatment of water and their overall use.

Explain to me how a basic water pump works.

"In my experience working with water pumps, they can be best summed up as using basic forces of nature to move a liquid. As the moving pump part begins to move, air is pushed out of the way. The movement of air creates a low-pressure vacuum which can be filled up by more air, or in the case of water pumps, water. There are several designs into how a water pump can function, with some built to move small scales of water and others designed to pump very high volumes."

Another simple, yet complicated question that may be posed to you during your interview is asking you to demonstrate how a water pump works. This is yet another test to ensure you have the basic knowledge required for this role as a water treatment operator.

Be sure to answer this in an easy-to-understand way and explain the basic functions of a water pump system. The more simply you can answer how a basic water pump works, the more confident you will sound. If you need to, be sure to research the basics of water pump principles and come to your interview ready to explain how air is used as a vacuum to move water through a system.

How familiar are you with different types of pipe valves? If possible, name a few that you are familiar with.

"I have some familiarity with different types of valves and have used check valves and butterfly valves in some plumbing projects that I have taken on. I know there are a host of others that are commonly used in water treatment facilities like ball valves to regulate pressure and flow, as well as newer solenoid valves for automatic flow control. Are there other types of pipe valves that I would be frequently exposed to in this role as a water treatment operator?"

Whether you have direct experience in the water treatment process or not, you can surely expect some technical questions that relate to the job. With this question, your interviewer is hoping to hear that you are familiar with the different types of pipe valves and are hopefully aware of the common ones that are used in the treatment of water.

If you have experience in working with different types of pipe valves, you can list the types of pipe valves that you have worked with most. Some of the more common valves used in water treatment plants are ball valves, gate valves, globe valves, butterfly valves, and check valves. Try to conduct a bit of research on this topic prior to your interview so you can come prepared to speak knowledgeably on the subject.
