How to Overcome the "Yuck" Factor of Recycled Wastewater

For those of us who live in places where there is never any doubt about the ability to turn a tap and have clean water come out, it can be hard to reconcile the reality that the world is at great risk of a water supply crisis. In 2023, the UN estimated that not only do two billion people not have safe drinking water, but that two to three billion people are already experiencing water shortages for at least one month a year. The report also projects that the population facing urban water scarcity will double by 2050, due to the increasing frequency of extreme drought.

And drought isn’t the only supply issue — many groundwater aquifers have been overpumped for decades. The Ogallala Aquifer, the largest in North America, supplies 30% of the irrigation water in the United States, is the only reliable source of water in some parts of the American heartland, and will run out of water in a generation in the most vulnerable communities.

So what are we to do about our water supply problems? Yes, we could and should certainly try to use less water, look for other surface water sources, or even pump water back into depleted aquifers.

We could also recycle our wastewater. But, well. That seems “yucky” to a lot of people.  

In Tampa, former Florida state representative and state senator Janet Cruz lost an election in 2023 to the Tampa City Council, largely attributed to her support of laws allowing treated wastewater into drinking water systems while she was a state legislator. In a survey conducted for research published in the Science of The Total Environment journal last year, it was found that just 43% of respondents in the Southeast US supported water reuse generally — and only 8% would be willing to drink recycled water.

But the fact of the matter is that the rest of our water sources cannot be relied upon as we continue to use them in unsustainable ways, and the total volume of our wastewater represents an invaluable opportunity to reshape our water future, if we can just get beyond that “yuck factor.”

To that end, the State Water Resources Control Board of California voted in December 2023 to adopt regulations to implement direct potable reuse (DPR) in the state — in other words, that means treating wastewater to the point that it can be added directly into drinking water systems, with no environmental buffer. The vote was years in the making and the development of the regulations mandated by state law.

California, with its population of 40 million and extremely high demand for agricultural irrigation water, faces the stresses of water supply perhaps more than any other state. The move to implement DPR follows decades of indirect potable and non-potable reuse in the state (and many others in the country, like Florida). Treated wastewater is already being used for industrial machines, irrigation, and aquifer replenishment.

At the time the legislation went through, the Metropolitan Water District alone (the water agency of Southern California) was projected to provide 115 million gallons of recycled water a day by 2032, which could supply 385,000 homes. Gov. Gavin Newsom projected that recycled water could account for 9% of state water use by 2030 and then double by 2040.

The statewide regulations officially allowing for DPR in California went into effect in October of last year. By then, cities like Santa Monica were hoping to implement DPR as early as 2027. Plans for a full DPR treatment facility in the San Fernando Valley to be completed by the same time point are underway. These rules also allow water agencies flexibility in their supply management between wet and dry years, meaning that the objective is that drinking recycled water will help the agencies save water from the Colorado River and Sierra Nevada snowpack for drier years.

But for all the high hopes in California, the state won’t be the first in the nation to treat its wastewater to drinking water quality. The city of Big Spring, Texas, was the first place in the country to use DPR to supply its water system, which it began in 2013 after its namesake spring ran out of water. The standard bearer of water recycling, though, is Singapore, which through its Changi Water Reclamation Plant cleans 237 million gallons of wastewater a day and brands the treated water as “NEWater.”

And California won’t likely be alone as the sole mass consumer of wastewater-turned-drinking-water in the US either. The city of El Paso is expected to have a DPR plant online by 2027, as Texas allows such plants on a case-by-case basis. Colorado actually beat California to adopting DPR regulations in February of 2023, which were the first in the nation. And despite Cruz’s loss in the Tampa City Council election, the practice is still moving forward in Florida, where a pilot program in a central Florida county began turning wastewater to drinking water in late 2023.

Finally, Arizona also began building a framework for DPR late 2023, where the need is increasingly being seen as inevitable. The state’s proposed rules are nearing approval.

Of course, building the needed facilities and the extensive water treatment process won’t come cheaply, especially for municipalities that aren’t quite the size of the whole state of California or even just El Paso. The DPR facility constructed by the Colorado River Municipal Water District for Big Spring, which has a population of around 25,000, cost $14 million to build and took 11 years to plan and construct. Getting other smaller communities on board before it’s absolutely necessary will likely not be easy.

But getting the infrastructure for DPR and other expanded water recycling systems in place now will be cheaper than in the future, when other water sources are even more stressed. And as with all things, as the wastewater recycling economy scales up, costs should come down. It’s already cheaper than desalination of saltwater — an International Finance Corporation estimate has found that the cost of producing potable water can be as low as $0.45 per cubic meter, while desalination typically exceeds $0.50 per cubic meter. A Framework for Direct Potable Reuse put together by water stakeholders including the WateReuse Association and the American Water Works Association also found the total estimated costs of DPR to compare favorably with the costs of other possible new sources of water.

So what does this all tell us about how we get people past that “yuck” factor? We might infer that when faced with nearly no other options, that factor simply goes away. But we don’t have to view recycling wastewater into drinking water as a last resort, either. While the intensive cleaning process isn’t cheap, it results in energy savings, environmental benefits, and water that is purer than many current drinking water sources, as noted by the California State Water Board chair. And who could reasonably argue that those are bad things?

In the end, shifting attitudes beyond the yuck factor may simply require some creativity and a massive PR campaign. Epic Cleantec, a water recycling company in San Francisco, developed a beer from recycled greywater from a city apartment building. Admittedly, greywater — the wastewater from sinks, showers, and laundry — is quite a different thing than the sewage that comes from toilets. But it’s wastewater all the same, and the company has found that people will usually try it. And it’s not the only wastewater beer that’s available, either.

But there’s far more opportunity for wastewater than just beer or even regular drinking water. In their reporting on the subject, Wired magazine posited that “the city of tomorrow will run on your toilet water” — because of the additional possibilities to extract compost and energy. Industries in the EU are already taking steps to get power, heat, and reusable chemical materials out of wastewater.

So as Wired put it, “It’s not gross. It’s science.”

Wastewater Continues to Provide an Effective Means to Track COVID-19 and Other Diseases

Tracking viral activity in wastewater emerged as a valuable way to map and monitor the spread of COVID-19 early on in the coronavirus pandemic. Many viruses can be tracked through wastewater data, as virus fragments can be excreted into wastewater even when individuals do not have symptoms of the virus. Wastewater operators send samples of untreated wastewater to laboratories, where technicians test the water to find out what viruses are currently circulating in a community. This can help public health officials guide their communities through infection prevention, testing, and vaccination, as necessary.

Poliovirus was the first virus widely tracked through wastewater surveillance, beginning in the 1990s as part of efforts to finally fully eradicate polio. But public awareness of this concept became more widely known with COVID-19. The height of  the pandemic has passed, but many tracking efforts continue in order to keep tabs on the disease’s current threat level and to advance continued research into it.

Newsweek continues to publish an updated COVID map each week showing the results of the past week’s viral monitoring across the United States. See the December 18 update here. It reveals the highest viral activity for SARS-CoV-2 virus (which causes COVID-19) in Arizona, New Mexico, Massachusetts, Minnesota, Missouri, and South Dakota.

The data for these updates comes directly from the U.S. Centers for Disease Control and Prevention (CDC), which also has multiple publicly accessible dashboards showing data for COVID-19 and other diseases tracked by the National Wastewater Surveillance System (NWSS).

Find the dashboards for the viruses tracked by the NWSS here:

• COVID-19
• Influenza A
• RSV
• Mpox

Many states also run their own dashboards of surveillance data for COVID-19 and other viruses, including:

• California
• Colorado
• New York
• North Carolina
• Wisconsin

Notably, California has also recently found H5N1 bird flu virus in the wastewater from cities like Los Angeles and San Francisco, reflecting the rise of avian influenza. The CDC has an avian influenza tracker as a subset of the Influenza A dashboard. As of December 14, the vast majority of H5N1 found in wastewater has been in California, with the most recent additional detections so far found in Nevada, Utah, Wyoming, and Texas. It has also been detected in Hawai’i.

Not every wastewater treatment plant in a given state participates in tracking, so it should be kept in mind that the available data is a snapshot of only a portion of the state’s population. Tracking programs can incur significant expenses for wastewater utilities that can be out of reach especially for smaller operations. But there are often opportunities to engage in partnerships with other entities to reduce or erase these costs, such as what the Abilene Taylor County Public Health Department recently began with Baylor University in Texas.

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

Emerging Contaminants and Your Onsite Wastewater Treatment System

When installed, operated, and maintained correctly, septic systems should not pollute groundwater or cause any danger to the drinking water supply. But the unfortunate fact is that pollutants and contaminants do make their way out of septic systems and into groundwater all the same. And this isn’t always to do with poor installation or maintenance — if a septic owner is putting things down their toilets and drains that aren’t meant to be treated by a septic system, these things become all the more likely to get into the groundwater. This is one of the reasons why making sure everyone knows the Three Ps of septic systems is so important! (That’s pee, poop, and toilet paper, of course).

A 2017 study in the journal Environmental Science & Technology showed that American septic systems are regularly depositing pharmaceuticals, consumer product chemicals, and other hazardous chemicals into the environment. Due to their presence in consumer and industrial products throughout society, such chemicals — often called contaminants of emerging concern or emerging contaminants — find their way into bodies and supplies of water in numerous ways, not just through septic systems. They can not only threaten public health by contaminating a human drinking water supply, but cause environmental problems for ecosystems and organisms as well. For instance, the feminization of male fish and fertility issues in other animals have been strongly linked to emerging contaminants.

This 2017 study suggests that besides emphasizing the need to avoid putting pollutants into a septic system, the best way to protect groundwater from septic contamination is keeping septic systems away from the aquifers and wells that supply drinking water. But, of course, many septic systems already exist in such a range and other solutions for preventing them from discharging too many emerging contaminants are needed.

While any chemical going into a septic system that isn’t one of the Three Ps is a contamination risk and absolutely should not enter a septic tank, some chemicals or contaminants will naturally be more of a cause for alarm than others. Right now, the pollutants society is likely most concerned about at large are PFAS compounds and microplastics, both of which have been found coming out of septic systems.

Though PFAS (Per- and polyfluoroalkyl substances, also commonly known as forever chemicals) have become a high-profile concern in more recent years, PFAS have been one of the most frequently detected compounds in drinking water wells since at least 2016, contamination which has been linked to septic systems.  

For more information on protecting groundwater from failing septic systems and forever chemicals, check out this article on the subject from SCS Engineers.

As for microplastics, the impossibly tiny bits of degraded plastic have been found everywhere from clouds to likely into human brains, and some believe septic tanks are the primary source of microplastics found in underwater drinking water reservoirs. The issue of microplastics in its totality certainly cannot primarily be blamed on septic systems, but figuring out how to decrease their presence in as many sources as possible is critical.

Another consideration with microplastics in septic systems isn’t just the environmental contamination — the buildup of solids in the system can also cause issues for the operation of the system. In fact, a 2015 Pumper Magazine article refers to microplastics as “tiny terrorists” in septic systems.

More to the point, microplastics are a type of solid that “remain[s] suspended are small rough to move readily through the screen and into the soil treatment area. If these solids are small pieces of organic material, they will break down or be consumed in the soil. However, if they are inert particles such as … plastics or other synthetic materials, they will not break down in the soil environment and will plug the soil pores, permanently reducing the ability of the soil to accept septic tank effluent. There is no fix when this happens other than replacement.”

Solutions to protect septic systems and the groundwater reservoirs they feed into from microplastics are hard to come by, short of emphasizing to septic owners the necessity of keeping everything but the Three Ps out of their systems and that they should try to buy fewer products containing microplastics to begin with.

How to Prepare a Septic System for a Large Event

Residential septic systems are designed to accommodate the wastewater from a specific number of people, typically judged by the number of bedrooms in the home. This normally doesn’t represent any issues for the regular residents, but the extra bathroom use necessitated by holding a large party or gathering can pose overload challenges for the septic system.

If a septic system is flooded by the overload of water from party guests in a concentrated timeframe, the overwhelming of the tank and drainfield could lead to sewage backups and flushing untreated effluent into the drainfield. In short, a quite possibly ruined party!

There are steps that homeowners can take to prepare for the impact on the septic system ahead of the party; mostly involving efficient use and management of water ahead of time. These are the steps advised by the septic education program at Michigan State University Extension:

• In the days leading up to the party, minimize the amount of water used for laundry, dishwashers, and showers.
• If the planned cooking is water intensive, do as much food prep and cooking ahead of time as possible.
• Rent a portable bathroom.
• Post bathroom rules to advise guests what can be flushed and other bathroom/septic safety tips.
• Have the septic system inspected and pumped before the party.
• Make sure that other outside sources of water, like eavestroughs or gutters, are routed away from the septic drainfield.

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.

Find your state OSHA office here >>

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.

How to Abandon a Septic System

There’s a number of situations in which a septic tank/system might need to be abandoned: replacing it with a new system, connecting to a city sewer, or abandoning a property altogether. Septic tanks, cesspools, leaching pits, dry wells, and everything related must be properly cared for and not simply left as they are. Most important is to ensure that access for future discharge from the system will never be possible.

Many states or localities will have specific requirements for procedures on abandoning a septic system. For example, you can take a look at the Minnesota Pollution Control Agency’s guidance on abandoning a sub-surface sewage treatment system, where several state codes are referenced.

According to Sara Heger, septic educator at the University of Minnesota, there are three common practices for what to do with the empty tank:

1. Remove and dispose of the tank at a landfill.
2. Crush the tank entirely and backfill the hole. Water has to be able to drain through it, so it must be completely broken.
3. Fill the tank with a material like concrete that won’t let liquids flow through. There must be no risk of collapse in this scenario.

Basically, you never want to have an abandoned septic tank lying out exposed like in the photo above! Before codes and regulations for old septic systems came into place, it was common practice to simply leave the tanks where they were and forget about them. But this is quite dangerous. Old homes that were hooked into a sewer system long after construction should be inspected for old septic systems when sold.

An improperly abandoned septic system poses several possible risks. They could collapse into sinkholes, spread disease if untreated waste comes into contact with groundwater, or release toxic gasses like methane and hydrogen sulfide.

Be on the lookout for these signs of an abandoned septic system that is leaking, from B&B Pumping in Fort Worth: excessive weed growth on a lawn or algae on a pond, a perpetually soggy patch of lawn, an area of lawn that smells like human waste, unstable and sinking land, or pipes physically protruding from the ground.

Building over the top of even a properly abandoned septic tank isn’t a good idea, since sinking problems or leaked pollution could still occur if the area isn’t handled with care.

Costs of an Onsite Wastewater System

How much does a septic system cost in 2024?

There’s no simple answer — the cost of every single onsite treatment system is going to vary according to a number of factors. What we can tell you is this: as of 2024, HomeAdvisor.com, which aggregates home improvement and maintenance resources, lists the typical range of septic projects to cost between $3,484-$11,703.

The basic factors that HomeAdvisor identifies as driving the cost variations include the size, type, and material you need for the system. Be aware that these three key factors, as well as some others, can drive your costs up well beyond the upper end of that range.

Visit HomeAdvisor for a detailed breakdown of the ranges of costs for tank size, anaerobic vs. aerobic system tanks, types of alternative systems, material types, installation add-on costs, replacement costs, and more.

You can also get an estimate of the costs for your specific project’s needs, by entering information into their estimate tool. For the sake of accuracy and due diligence, it’s recommended to have at least 2-3 cost estimates before determining a final estimated price.

To find other septic professionals in your area, check NOWRA’s Septic Locator lookup tool. You’ll want to be able to list other septic professionals as references for your work, or to check the cost estimates with, when engaging with new potential clients. Networking is important!

So what do you do if you need help financing your septic project? Thankfully, there’s a number of resources available for assistance. You may want to visit the Financing page at the National Onsite Wastewater Recycling Association website — NOWRA has a long list of sites and organizations to visit for assistance, including the Environmental Protection Agency, the Department of Housing and Urban Development and the Department of Agriculture, and more.

Some other resources we would like to particularly recommend:

• The Rural Community Assistance Partnership (RCAP) provides technical assistance and support to rural communities across the country. Their Water and Wastewater Technical Assistance Program has a special focus area in onsite/decentralized wastewater. While RCAP’s national organization does not provide services directly, their regional offices can assist with coordinating help for your community. Contact RCAP here.
• The Financing Septic Systems module in the EPA’s Water Finance Clearinghouse. The module is for homeowners seeking information to support the operations and maintenance, repair, or new construction of septic systems.
• Septic at EPA — Along with a host of other septic-related information and resources, the EPA has funding sources listed by federal programs, individual states, and tribal communities.
