Essential Skills for Modern Wastewater Operators

One of the greatest selling points of a career in wastewater treatment is the lack of requirement for a college degree in order to enter the field. However, that in no way means that working in a wastewater treatment plant is an unskilled occupation. There is a vast array of skills that are needed in the day to day operation of a plant. How many of them any individual operator needs varies on the size and other particularities of the plant and staff, interests of the operator, and desire to progress further up the career ladder.

Here, for the benefit of those trying to determine if wastewater treatment is the field for them, we take a look at the broad categories of skills that operators must have and a couple more that are a great benefit in addition. We will also include example training resources and events for each category of skills that can be found on WaterOperator.org.*

*Sample training events will likely have already occurred, and serve as examples as types of events to look for in the future.

Operation & Maintenance of Machines and Other Equipment

Wastewater treatment plants are composite mechanical networks of pipes, pumps, machines, and other equipment. In order to operate and maintain each essential piece of the network, a plant’s employees need to be able to work with and understand machines, tools, technology, and heavy equipment. While prior experience in this area is not generally required, it can certainly help new operators.

Training resource: “Operator Certification: Mechanical Systems” Webinar from the Environmental Finance Center Network
Training events: “Mechanical Maintenance and the Operator” from Maryland Center for Environmental Training, “Operation of Wastewater Treatment Plants” from Pennsylvania Rural Water Association, “Wastewater Pump School” from Smith and Loveless

Math & Science

Math is one of the most important skills in wastewater treatment. Operators use mathematical formulas to determine flow levels, chemical concentration, and other treatment requirements. Understanding the chemistry and biology of the treatment process, and even the physics of water, is also a significant advantage for operators.

Training resources: “Sidney's Big Book of Water and Wastewater Math” from the Indigo Water Group, “Problem Solved: Pump Discharge Rate” — or any other wastewater math video by the American Water College, “Microbiology of Wastewater Treatment” Webinar from the US EPA
Training events: “Wastewater Math” from the Environmental Finance Center Network, “Disinfection in Water and Wastewater” from Enviro-Clear, “Wastewater Microbiology and Microscopy” from the Wisconsin Wastewater Operators Association

Analysis

Another prominent duty in wastewater treatment plants is sampling, testing, inspecting, evaluating, and analyzing water quality, machinery, and overall process control. Some plants may have their own labs for water quality testing, and even a dedicated lab staff, but even if not, the everyday job of an operator requires attention to detail and the ability to carefully analyze the treatment process in a number of different ways.

Training resources: “A Look at the Wastewater Treatment Plant Laboratory” from the Tennessee Department of Utility Districts, “Biosolids and Sludge PFAS Sampling Guidance” from the Michigan Department of Environment, Great Lakes, and Energy
Training events: “Wastewater Lab Series” from the Tennessee Department of Environment and Conservation, “Wastewater Sampling and Preservation” from the Great Lakes Community Action Partnership

Safety

Safety is of the utmost importance in a wastewater treatment plant. Staff must know and follow all safety rules and regulations, know how to administer first aid, and be able to handle chlorine and other hazardous substances.

Training resources: See our recent “Learning About Safety in Wastewater Treatment Plants” blog post!
Training events: “Water and Wastewater Workplace Safety” and “Operator Health & Safety Survival Guide” from the Pennsylvania Rural Water Association, “Confined Space Awareness” by Hardin Associates & Consulting, “OSHA Basics and Beyond” from Tighe and Bond

Physical Capacity

This last category is really a set of personal capacities that cannot generally be taught. First and foremost, a wastewater treatment operator must be willing to work with and around human waste — and all of the odors and mess that entails. An operator also needs the ability to work with their hands on physical tasks and to be willing and capable of working in unpleasant weather conditions. If these are unacceptable working conditions for you, wastewater treatment is not likely to be your path!

•••••

Another technical skill that can be hugely beneficial in a treatment plant, but isn’t so much a requirement, is electrical handling. Electricity is an important component of plants, and while not everyone needs to be an electrician, basic knowledge and ability can only help you. Check out resources like “Combined Heat and Power Microturbines” and “Power Resilience Guide for Water and Wastewater Utilities” to get a sense of the importance of electricity in wastewater treatment, or look for events like “Basic Electricity for Water and Wastewater.”

Finally, much like nearly any job, having good people skills (or “soft” skills) can go a long way in this field as well, especially if you’re interested in progressing up into management. Communication, networking, conflict resolution, leadership, problem-solving, time management: All skills to develop that make nearly any job easier to handle!

Texas Water Supply Endangered by Workforce Shortage

Texas is facing a critical challenge that could eventually impact its water supply and infrastructure. A recent report highlights a growing concern for Texas' water supply due to a significant labor shortage in the water and wastewater utilities sector. 

The Texas Water Foundation and Texas Rural Funders released the report, compiled by Jobs for the Future, which underscores the critical role of skilled workers in maintaining the state's water infrastructure. This shortage poses a serious threat to the state's ability to maintain and repair its water systems, which are already under strain from climate change and a growing population.

The report warns that the next failure in Texas' water system could be exacerbated by workforce issues, such as unfilled positions leading to delayed repairs or inadequate training. The San Antonio Water System (SAWS) is among the agencies facing these challenges, with a substantial portion of their workforce nearing retirement and a shortage of qualified replacements.

To address these issues, the report suggests developing regional training programs, integrating water careers into existing education initiatives, and establishing a dedicated water fund for infrastructure. SAWS has implemented a policy to retain employees by offering raises for new certifications, aiming to keep skilled workers within the organization.

The labor shortage in Texas' water and wastewater utilities sector is a pressing issue that requires immediate attention. By developing regional training programs, integrating water careers into education initiatives, and establishing a dedicated water fund for infrastructure, Texas can work towards a sustainable solution. The efforts of agencies like SAWS to retain skilled workers through incentives are steps in the right direction.

Pathways for Career Development in Wastewater Treatment

Everyone in and around the water sector knows that there is a staffing and workforce shortage in treatment plants around the country, both in drinking water and wastewater. Much of the issue is due to the significant number of operators that have retired or are approaching retirement age, while replacement workers beginning careers are not entering the sector at a high enough rate.

As such, the question of how to recruit more younger workers has been a major focus of the water sector in recent years. Many of the recruitment issues are similar on the water and wastewater sides (less interest in trades and manual labor, lack of awareness that the jobs exist, competition from other industries), but wastewater has the added challenge of convincing young people to work with human waste.

However, when considering joining the wastewater treatment field or trying to recruit others, something important to look at are the opportunities for advancement and professional growth — in other words, the options for career development. Because the details and daily tasks of a wastewater operator’s job aren’t necessarily widely known, someone may incorrectly think that the opportunities for professional growth are limited.

In fact, that is not the case. Here, we take a look at some of the best ways to advance as a wastewater operator.

Advanced Certification and Licensing

Every state requires prospective wastewater treatment operators to obtain a license in order to perform the job. While the exact requirements for licensing are different across the states, typically they require the passing of a certification exam and completing continuing education courses to renew licenses at set intervals.

But in most states, there are higher levels of certification available beyond the basic license needed to become an entry-level operator. These advanced licenses are often labeled as Class II, Class III, Class IV, or perhaps even higher. To obtain a higher level license, a certain number of years of experience, continuing education credits, and passing more exams are typically required. Having high level licenses will help to open up more advanced positions and a higher pay grade.

Specialization

Another path to more responsibilities and higher wages is specializing in particular components of the wastewater treatment process. Possible specializations include industrial wastewater, laboratory analysis, environmental compliance, process control, maintenance, and biosolids management. Certifications for these specializations are often available. Getting an official specialization certification may not always be required, but is usually very helpful.

Supervisory and Management Positions

As with most jobs, there are supervisory and management roles at wastewater utilities that can be achieved with experience and competence. Progress high enough up the management ladder, and you can oversee plant operations and staff, enforce regulatory compliance, make financial decisions, build your plant’s workforce, and more.

Pursuing Higher Education

One of the reasons that water and wastewater treatment are excellent career choices is that becoming an operator does not require a college degree. But it’s also true that having degrees can open more doors for advancement in these fields. Associate’s degrees, bachelor’s degrees, or even higher level degrees in fields like environmental science, engineering, biology, chemistry, information technology, business administration, and beyond can enhance an operator’s skill sets and provide significant benefits to their utility.

Joining Professional Organizations

Being a part of professional organizations in any field is a great way to further professional development. These organizations provide consistent opportunities to network, attend conferences, access cutting edge training, join leadership and advisory committees, and possibly achieve industry recognition.

Here are some of the top national professional organizations to check in the wastewater industry:

• Water Environment Federation (WEF)
• National Rural Water Association (NRWA)
• American Water Works Association (AWWA)

You could also check out the National Onsite Wastewater Recycling Association (NOWRA) and the National Association of Wastewater Technicians (NAWT), which are focused on onsite and decentralized wastewater (septic) systems, if you live in an area where such systems are incorporated into utilities.

Many states also have state level affiliates of WEF, NRWA, AWWA, and NOWRA. If possible, being a part of both your state organizations and national organizations will maximize development opportunities. Your state may also have an organization that is independent of any of these bodies, like the Wisconsin Wastewater Operators Association.

The Impending Workforce Shortage in the Water Sector

There's a lot to think about when it comes to threats to our drinking water systems. Climate change, aging infrastructure, and cybersecurity are hot-button, current issues that we've all heard plenty about over the past few years. While these issues continue to threaten the safety and security of our drinking water, there is another issue on the horizon that we must not lose sight of. This is, of course, the impending workforce shortage in the water sector. We have highlighted some key takeaways from Bloomberg's December 2024 article "America’s Next Water Crisis? A Lack of Experienced Workers."

"Nationwide, many of the roughly 1.7 million people employed in the water sector have hit or are nearing retirement age. In total, between 30% and 50% of the workforce will retire in the next decade and there aren’t enough younger workers in the pipeline to replace them. A Brookings Institution analysis of 2021 data found that 88% of treatment plant operators were aged 45 or older, compared with 45% nationally."

The National Rural Water Association (NRWA) has been surveying water workers to get an idea of how widespread the shortage is and they're finding that succession planning hasn't been happening as much as it needs to be across the country, but specifically in rural areas. Many rural municipalities cannot afford to hire more than one water operator and sometimes one operator is responsible for the water systems of multiple small communities. This makes it difficult to hire an apprentice or operator-in-training since the budget may not always allow for that.

Another issue is that it's not just about finding workers who can pass the necessary certification exams and requirements, the sector needs workers who have real life work experience. It is urgent that the water sector starts to recruit now so the incoming workforce has the opportunity to get hands-on training and learn from their more experienced colleagues. There are some efforts underway to try and get younger workers interested in the water industry. "The National Rural Water Association, through its state affiliates, has launched an apprenticeship program. Veolia North America, formerly known as Suez, opened Veolia Academy, its in-house training program, to the public in 2023 to help water workers pass state certification exams."

It is important to promote this field of work to younger generations who may not know that water jobs even exist. Many who work in the water sector find that they end up in the industry incidentally, and hadn't necessarily known this was a career path until they stumbled upon it. Some great things to advertise about water jobs are:

• Competitive pay rates: The 25th annual Water and Wastewater Utilities Compensation Survey showed that from 2021 to 2022, large utilities’ salaries increased 1.7% and small utilities’ salaries increased 1.9%. Medium-sized utilities’ salaries showed the most significant increase at 8.7%.
• 53% of water workers have a H.S. Diploma: This means that many water jobs don't require much formal education in order to earn a living.
• Not a traditional desk job: The jobs that need to be filled include construction style work such as repairing water mains, working in water treatment facilities, and managing wastewater.

It is crucial to increase visibility of the industry if we want to stop the workforce shortage before it becomes a bigger problem. Water is "out of sight, out of mind,” said Shannan Walton, who runs workforce development for NRWA. “Even in disasters, the heroes are the linemen because you can see them climbing the poles and they're fixing everything for the communities. Water and wastewater is invisible."

OSHA Requirements for Pumpers

It’s never a bad time for a refresh on the requirements of the Occupational Safety and Health Act (better known as OSHA). The act, passed in 1970, comprises a set of federal standards for workplace safety, but it also allows individual states to submit and operate their own safety plans and requirements. State plans may cover all workers in a state, or may only cover state and local government workers only. It is important to know which category your state falls under.

OSHA state plans covering private and state/local government workplaces:
Alaska, Arizona, California, Hawai’i, Kentucky, Indiana, Iowa, Maryland, Michigan, Minnesota, Nevada, New Mexico, North Carolina, Oregon, Puerto Rico, South Carolina, Tennessee, Utah, Vermont, Virginia, Washington, Wyoming

OSHA state plans covering only state/local government workplaces:
Connecticut, Illinois, Maine, Massachusetts, New Jersey, New York, Virgin Islands

No state plan, follows federal OSHA plans:  
Alabama, American Samoa, Arkansas, Colorado, Delaware, Florida, Georgia, Guam, Idaho, Kansas, Louisiana, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Dakota, Northern Mariana Islands, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Dakota, Texas, Washington D.C., West Virginia, Wisconsin

State plans often don’t differ drastically from the federal OSHA plan, but the states of California, Michigan, Oregon, and Washington do have plans with substantial differences from the federal one.

If you are in need of assistance in identifying and/or fixing workplace safety issues, most states do have consultation services available for free as part of the On-Site Consultation Program. Other OSHA programs workplaces can participate in include the Alliance Program, the OSHA Strategic Partnership Program, the Voluntary Protection Programs, and the OSHA Challenge Program.

Read more about the OSHA cooperative programs here >>

Keep in mind that the supervisor or crew leader of an onsite/decentralized wastewater work crew will typically be the OSHA competent person (unless there is a different employee specifically assigned to oversee safety). Whoever is in charge of safety, they must be able to identify critical issues, know and follow OSHA requirements, enforce a written safety plan, and create a culture of safety for the workforce.

The top reasons for accidents include rushing, poor concentration, and simply being in the wrong place at the wrong time. A comprehensive safety plan can help address some of these causes and minimize damages after accidents do occur.

Elevating Women in Water

Contributed by Margaret Golden

Women make up over half of the population, but account for less than 20% of workers in the water industry. The work that women contribute to the water industry is necessary and important, offering valuable insight to bring the industry into the future.

With a new generation of workers on the rise, it is important that women feel empowered to work in the water. Brianna Huber, chemist with the City of East Moline, is on a mission to not only recruit women into the industry but see equity in their opportunities. Her non-profit, Her2O, is currently seeking members who are ready to forge lasting change.

Women across the country are already making great impacts, breaking glass ceilings and blazing their path to the top of the water world. Two leaders in the water industry recently discussed what it means to them to be a woman in the water industry.

Newsha Ajami, the Director of Urban Water Policy at Water in the West at Stanford University, discussed in a podcast what we need to do to transition to 21st century sustainable water management. Michelle Harrison talked about her favorite parts about working as a wastewater treatment operator at the Northwestern Water & Sewer District.

Many organizations take the time to specifically acknowledge the women in their work place during women's history month. Last spring the U.S. EPA highlighted Sandhya Parshionikar, Director of the Water Infrastructure Division, Center for Environmental Solutions and Emergency Response. Rural Communities Assistant Partnership highlighted Ines Polonius, CEO of Communities Unlimited.

Cuyamaca College in El Cajon also hosts an annual symposium dedicated to Women in Water.

The tool is free to use and correct answers are provided, along with linked references to WEF's publication store.

Study guides and test preparation resources are a popular topic on our blog, including this post on studying for certification exams.

The Next Generation of Water Workers

The value of clean, safe water (and the essential water workers who provide it) has been in the spotlight during the COVID-19 pandemic. However, according to a report from the Brookings Institution, approximately 3 million workers will need to be replaced within the next decade. Who will be the next generation of water workers? This is a question that the American Public Works Association and many others are thinking about as the current water workforce heads toward retirement. 

Various entities such as the U.S. Environmental Protection Agency (EPA), the American Public Works Association, and Congress have all been working to tackle this important issue. The U.S. EPA announced its America’s Water Workforce Initiative late last year, using education programs and public outreach to help develop water as a career of choice.

Other organizations like the American Water Works Association and the Water Environment Federation have also been working to tackle this issue. The two collaborated to create the Work for Water website, which has been recently updated, to serve as a fantastic resource to find jobs and prepare individuals for water related careers.
