Learning About Safety in Wastewater Treatment Plants

Establishing, following, and training for rigorous safety protocols is critical to the successful operation of a wastewater treatment plant. Not every safety incident is as severe as the 2006 Bethune Point Wastewater Plant Explosion that’s detailed in the video above, but that incident is an effective example of how horribly wrong things can go when safety protocols are lax and safety training for operators is minimal.

If you are seeking to learn more about safety in the wastewater treatment industry, a good first stop would be the Occupational Safety and Health Administration (better known as OSHA), a division of the US Department of Labor. It was created by the Occupational Safety and Health Act of 1970, which also laid out a set of federal standards for workplace safety.

However, the act also allows individual states to submit and operate their own safety plans and requirements (which are generally fairly close to the federal plan anyway). State plans may cover all workers in a state, or may only cover state and local government workers only.

Here’s the breakdown of each state’s OSHA classification:

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

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

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

*California, Michigan, and Oregon are the three states in which the state OSHA plans contain substantial differences from the federal OSHA plan.

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.

A great introduction to OSHA and other safety regulations through the lens of wastewater treatment is this recorded webinar in the Environmental Finance Center Network’s wastewater operator certification series.

The main topics covered in the webinar include common hazards in wastewater treatment plants, personal protective equipment (PPE), confined space entry, equipment lockout/tagout procedures, hazardous chemical communication and safety data, excavation safety, and blood-borne pathogen standards.

Other common safety challenges to be cognizant of in wastewater treatment plants include slips and falls (due to the abundance of water in a facility), caught or crush hazards from moving machinery, and general good hygiene standards.

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 Potential of Artificial Intelligence in Wastewater Treatment

The need to conserve water and manage it more efficiently is perhaps now more dire than it ever has been. Among other water consumption issues: We have a record, still-growing population on the planet; accelerating levels of drought worldwide; and the artificial intelligence (AI) boom is guzzling water at a dazzling rate in order to keep data servers running.

Ironically, though, AI might just also be essential to redefining and maximizing the efficiency of our water use, along with similar emerging digital technologies like machine learning (ML), automation, and digital twins. These technologies can create “smart water” systems for industry — A concept that’s been primarily associated with drinking water, but is also starting to blossom in the wastewater sector as well.

Around two trillion gallons of treated wastewater are lost in the United States each year, which is a massive blow to US business and the environment. AI, ML, digital twins, and automation have the potential to mitigate the infrastructural inefficiencies that cause this water loss by optimizing water use, reducing the loss, and helping to build circular water management systems/economies that will emphasize reuse and minimization of use/waste across all sectors of industry.

In wastewater treatment plants specifically, these technologies can assist in understanding a system’s rate of flow, optimizing and saving energy, and providing data that is a useful tool in the decision-making process. These benefits would add up to significant cost savings in both expenditures and labor, and more importantly contribute to lessening our environmental burdens and increasing sustainability.

Wastewater Digest, which is following the expansion of AI and its sister technologies in the wastewater sector closely, says industry should implement these actions in order to reduce and optimize industrial water use:

• Assess and monitor water use with smart technology
• Invest in digital technologies like AI, ML, and digital twins
• Automate water management operations to maintain optimal performance
• Foster cultural sustainability so that everyone contributes to saving water
• Collaborate across industry to amplify results

Flushable Wipes: The Bane of the Wastewater Industry

In the video below, featured on Icon Water's YouTube channel, they test a "flushable" wet wipe to see how well it dissolves in water compared to toilet paper, wet wipes (not labeled flushable), and paper towels. All 4 products are spun for 30 minutes in water to display how well each of these products breaks down when you flush them. 

Flushable wipes have been the plague of the wastewater industry for years due to the problems they cause for systems. Not only can they clog pipes, damage equipment, and harm the environment, but they require increased maintenance for utilities. 

The most recent legislation regarding flushable wipes is the Wastewater Infrastructure Pollution Prevention and Environmental Safety (WIPPES) Act. This bill was passed by the U.S. House of Representatives in June 2024. This act "would require the Federal Trade Commission to create a uniform label for products that have and/or require a 'Do Not Flush' label" in order to reduce consumer confusion and help to protect wastewater systems. Additionally, Michigan recently passed a law in July 2024 that prohibits manufacturers from marketing wipes as “flushable.”
