The maritime industry is entering a new era of strict environmental accountability—and the pressure is immediate. Ships, barges, offshore platforms, and floating accommodations are facing non-negotiable wastewater compliance requirements, creating demand for advanced treatment systems. Yet despite its scale, this $17-billion compliance market remains underserved by land-based wastewater professionals.

For septic companies, this is a rare opportunity hiding in plain sight. The expertise required to maintain, install, and troubleshoot complex wastewater systems already exists.

SludgeHammer’s MARPOL-certified marine wastewater treatment system offers a proven, globally accepted solution for septic companies to enter this market with confidence.

What is MARPOL?

MARPOL is the International Maritime Organization’s main global treaty for preventing pollution from ships. It covers everything from oil and garbage to air emissions and sewage. Annex IV focuses specifically on sewage, setting the rules for how vessels must manage, treat, and discharge wastewater. 

Annex IV applies to:

• Ships ≥400 Gross Tonnage, or
• Any vessel carrying 15 or more persons, including crew

Under these rules, discharging untreated sewage is prohibited. Even treated sewage can only be discharged under strict conditions:

• 3 nautical miles offshore for pulverized and disinfected sewage
• 12 nautical miles for untreated sewage (where allowed)  

Why Treatment Plants are Now Essential

The most reliable long-term solution is a certified on-board sewage treatment plant. These systems allow vessels to discharge treated effluent closer to shore and into designated special areas—such as the Baltic Sea—as long as they meet the MEPC requirements 227(64) for effluent standards.

Traditional solutions, such as holding tanks and manual pump-and-haul methods, simply aren’t suitable or practical. They come with: 

• High costs
• Operational downtime
• Compliance risks at international ports
• Limitations for vessels operating in remote or environmentally sensitive regions

Modern marine operations now depend on certified, automated wastewater treatment systems.

The SludgeHammer Solutions: MARPOL-Certified Marine Wastewater Treatment 

SludgeHammer offers one of the industry’s few fully MARPOL-certified marine wastewater treatment systems, making it a powerful entry point for septic companies entering the marine compliance market. 

The system is backed by Lloyd’s Register, making it approved for use in oceans and ports worldwide, ensuring environmental compliance and performance. 

Technology & Effluent Quality

At the heart of every SludgeHammer is the Aerobic Bacterial Generator (ABG)—a highly efficient biological treatment engine. 

Key advantages include: 

• Rapid biological breakdown of organic waste
• Extremely low sludge production
• High-quality effluent that meets or exceeds MARPOL discharge criteria
• Reduced maintenance compared to traditional STPs

The result is a compact, reliable, and easy-to-service solution—a perfect fit for marine environments where uptime, compliance, and simplicity matter.

Beyond the Cruise Ship: Identifying High-Value Marine Assets

The biggest opportunities aren’t always on cargo vessels or cruise liners. In fact, the most underserved and profitable sectors are often semi-stationary or remote-operation environments that desperately need certified wastewater solutions.

Some of these operations include:

Floating Hotels (Coastels)

These high-capacity accommodations often support 200–800 workers in remote marine settings. They need robust, self-contained treatment systems with zero reliance on shore infrastructure.

Offshore Platforms & Oil Rigs

With no access to municipal sewer systems and strict regulatory scrutiny, treatment plants must meet MARPOL standards and withstand extreme conditions.

Port Facilities & Shipyards

Maintenance barges and temporary housing units generate large wastewater volumes where pump-outs can be logistically complex and expensive.

Large Private Yachts & Superyachts

Owners and captains demand quiet, compact, environmentally responsible systems—especially to access protected marine zones.

All of these represent high-ticket, long-term service opportunities for technicians who understand wastewater management.

Case Study Spotlight: The Bibby Progress Floating Hotel

When Chevron needed housing for 750 workers at a remote gas plant in Nigeria, wastewater management posed a major challenge. With no local sewer access and pump-and-haul costs too high, Bibby Maritime’s floating hotel required a self-contained system. SludgeHammer stepped in to deliver.

Using its ABG technology, SludgeHammer built an onboard wastewater treatment system for the barge, processing over 50,000 gallons daily and meeting strict environmental standards. In just a month, the retrofit was completed, ensuring reliable sanitation for years to come.

Concrete septic tanks are built to last, but in the real world, many fail earlier than expected. The hidden culprit? Acidic conditions created inside the tank itself. For septic service companies, that means more emergency calls, more customer complaints, and more tanks needing premature replacement.

With a SludgeHammer® solution, this can be prevented—not by coatings or additives, but by fixing the biological cause of acidic damage. Keep reading to learn more. 

Stop Corrosion in its Tracks

SludgeHammer® offers a rigorously tested and proven system that prevents septic tank concrete degradation by transforming the internal microbial environment. Instead of acid-producing bacteria dominating the system, SludgeHammer® restores balance, protects concrete surfaces, and dramatically extends the tank life.

The Problem—Acid Production Destroys Concrete from the Inside Out

Concrete degradation in septic tanks happens because of a microbial chain reaction: 

1. Wastewater produces hydrogen sulfide gas (H2S): This naturally occurs in anaerobic, low-oxygen systems.
2. H2S converts to sulfuric acid (H2SO4): Specialized bacteria in the tanks oxidize H2S into sulfuric acid. 
3. Sulfuric acid attacks concrete: The reaction dissolves the cement paste, leading to:
   • Surface pitting
   • Spalling
   • Softening and erosion
   • Structural weakening
   • Premature tank failure

Once sulfuric acid starts attacking the concrete, degradation accelerates quickly—particularly in older tanks or systems with high organic loading. 

For septic installers, pumpers, and service providers, this means more failed tanks and more replacement conversations with frustrated clients. 

The SludgeHammer® Solution: A Microbial Barrier that Stops Acid at its Source 

SludgeHammer® systems fundamentally reshape the internal biology of a septic tank. Instead of allowing the tank to remain an anaerobic, low-oxygen environment where corrosive byproducts form, SludgeHammer® introduces controlled aeration and its proprietary SludgeHammer Blend™ of highly active aerobic bacteria.

This combination creates a stable, oxygen-rich treatment zone where:

• Organic solids are rapidly and efficiently broken down by aerobic microbes.
• Anaerobic niches disappear, removing the conditions sulfur-reducing bacteria depend on.
• Hydrogen sulfide (H2S) production drops dramatically because the microbes that generate it can no longer thrive.

With H2S suppressed, the next step in the corrosion chain—its oxidation into sulfuric acid—simply can’t occur. The result is a microbial barrier effect that stops concrete-eating acid at its biological source, protecting the tank structure and preventing long-term degradation.

The Cost Advantage: Extend Tank Life Instead of Replacing It

Concrete tank replacement can cost thousands—and for commercial, industrial, or multi-tank systems, tens of thousands. By preventing acid-driven corrosion, SludgeHammer®:

• Reduces premature tank replacement 
• Cuts down on emergency failures
• Protects customers’ investments
• Minimizes warranty claims or callbacks for septic service companies
• Improves overall performance, leading to happier long-term customers 

When a tank lasts 10 to 20 years longer because the risk of septic tank concrete degradation is eliminated, the cost savings for property owners are substantial, putting you in a unique position that competitors simply can’t match. 

Protect Your Clients’ Tanks—and Build a Stronger Service Program

Concrete degradation is one of the most expensive and preventable causes of septic system failure. With SludgeHammer®, you can prevent septic tank concrete degradation by targeting the microbial cause at the source.

If you want to offer your clients longer-lasting tanks, fewer failures, and better overall system health, SludgeHammer® is the partner to help you do it.

For installers, an IAPMO/UPC-certified retrofit septic system can rejuvenate, extend the life, and restore the performance of your client’s existing system. SludgeHammer® technology offers a faster, non-invasive, and highly effective alternative that will save you time and money.

With the SludgeHammer Aerobic Bacterial Generator (ABG), you can upgrade almost any existing septic tank into a high-performance treatment system—one that enhances, repairs, and restores without structural modifications.

Innovation Rooted in Biology

SludgeHammer technology was born from Dr. Wickham’s soil microbiology research. While studying how bacteria clean oil-contaminated soils, he developed the SludgeHammer Blend Bacteria—a proprietary mix of organisms designed to digest organic waste, restore soil health, and thrive under extreme conditions.

These specialized bacteria:

• Have a powerful appetite for carbon
• Survive and function in low-oxygen (anaerobic) conditions
• Ferment sugars and mucopolysaccharides for energy
• Remove nitrates and nitrites to extract oxygen
• Operate efficiently at low temperatures
• Form spores with minimal biomass
• Regenerate rapidly for continuous waste treatment

Dr. Wickham discovered that these powerful bacteria could do more than just treat wastewater—they could actually revive failing septic systems. By restoring the function of the disposal field and improving the quality of water released into the environment, they could greatly reduce the need for frequent maintenance and traditional pumping protocols. The key challenge was finding a way to create the ideal conditions inside the tank for the bacteria to thrive.

Enter the SludgeHammer. It uses this biological process to fix septic problems naturally—without digging up yards or replacing tanks. It works quietly inside the tank, powered by an above-ground air blower, and requires no heavy equipment or excavation, so landscaping remains untouched. By restoring the natural balance of bacteria, SludgeHammer eliminates odours, protects the leach field from future failure, and turns the treated water into a valuable resource that can even be reused for sub-surface irrigation. It’s a simple, clean, and sustainable way to repair and maintain septic systems—making it a smarter alternative to costly and disruptive traditional methods.

The term “septic” literally means infected with bacteria. Sepsis is a severe condition that kills thousands of people every year. So why would anybody want a “septic” tank out in their yard? It seems ridiculous, but for well over a century, septic tanks are what we have used to try to safely treat the human waste that comes from our toilets and other household plumbing fixtures. And if you look inside a typical septic tank, it looks and smells as bad as any septic wound.

Septic waste is so nasty because the septic tank is anaerobic, meaning “without oxygen .” The way traditional septic systems deal with this is to let the tank capture the solids, things like feces, food waste, or toilet paper, and hold them for eventual elimination with a pump truck. These solids obviously will clog up a disposal pipe, so the tank only lets the liquid portion out of the tank.

But the liquid still has a high concentration of dissolved organic material that will ultimately accumulate in the environment, spreading septic conditions everywhere. Obviously, a bad thing. This organic material can’t be digested without oxygen. The best way to remove it from the liquid is by letting bacteria use oxygen to convert organic carbon to CO2 gas, which can escape into the air, eliminating it from the water.

We do this with septic tank waste in the soil. Water moves through soil grains by the process of capillary flow. This is because water is unique. The way the hydrogens and oxygens line up makes the individual water molecule behave like a tiny magnet, with positive hydrogens on one side and negative oxygen on the other. The charge on the water molecule is attracted to the charges on the soil particles, and water creeps along the surface of the soil particles in a micro-thin layer. Since there are gaps between the soil particles, air can get in. This makes it readily available to the bacteria that colonize the grains in this liquid microlayer, giving them plenty of oxygen for digestion.

But capillary flow only works when there is an air/water interface. Too much water saturates the soil, and oxygen can’t reach the bacteria. Water does not hold much oxygen, so the bacteria use it, and the environment becomes anaerobic. With septic waste, we continuously send bacteria that live in our intestines via toilet waste. These bacteria live in an environment with enzymes and acids continuously attacking them, so they protect themselves with a layer of mucus. When they get in the soil, they will be killed by oxygen if conditions stay aerobic. But in saturated conditions, only the anaerobic bacteria will survive, and they then secrete more mucus to protect themselves from the oxygen itself.

Mucus is an essential compound in nature. It serves a wide variety of functions in the living world. Chemically it is a sugar/protein combo that forms long chains. It creates very sticky conditions, and if it accumulates in soil, it will clog the soil so liquid cannot percolate through it. This is exactly why leach fields receiving septic waste tend to fail over time.

This all gets back to the question of why we have septic tanks. SludgeHammer was created to eliminate septic tanks, not by removing the tank, but by removing the septic conditions. We do this with air and with a unique blend of bacteria. The SludgeHammer bioreactor uses air to circulate tens of thousands of gallons through it every single day. Our SludgeHammer Blend™ bacteria are introduced into it, creating a colony of bacteria that consumes virtually all the organic matter that normally creates nasty anaerobic conditions in the tank.

But these bacteria have a special feature that makes them crucial to the life of the soil surrounding the leach system. These bacteria are called “facultative” because while they need oxygen, they can get it from the air, but they can also get it in chemical form from foods that contain oxygen. These include any sugar compound. Sugar is C6H12O6 which means each molecule has six oxygen atoms in it. And, since the mucus slime that clogs leach fields is a long-chain sugar molecule, our bacteria can digest it through fermentation. So even if there is no oxygen in the leach trench, it’s there for our bacteria in the food. The mucus disappears, and the waste gets the processing it needs in the soil to protect the environment.

Septic systems are essential to many homes, especially in rural areas where connecting to a public sewer system may not be possible or cost-effective. Septic systems are underground wastewater treatment systems that are designed to treat and dispose of household wastewater onsite. In this blog post, we’ll explore how a septic system works, the role of bacteria in a septic tank, how to maintain a septic tank, why septic systems fail, the signs of a failing system, and a new solution called SludgeHammer®.

Components of a Septic System 

A septic system consists of several components that work together to treat and dispose of household wastewater. The main parts of a septic system include:

1. Inlet Chamber: The first and largest part of the tank, where heavy solids, toilet paper, feces, and food from the kitchen are retained.
2. Baffle Wall: This wall separates the inlet chamber from the outlet chamber and allows the liquid portion of the waste to pass to the next chamber.
3. Outlet Chamber: The second chamber provides extra time for separating and settling solids.
4. Tank Outlet: The outlet from the tank usually has a vertical Tee, so the liquid passing out of the pipe from the tank goes down below any scum that might be floating to get into the pipe to go to the leachfield.
5. Leachfield: The leach field usually consists of gravel-filled trenches with a perforated pipe. The liquid flows out of the tank, down the pipe, and over the gravel, where it can percolate into the soil.

Bacteria in a Septic Tank 

Septic tanks rely on bacteria to break down waste. The bacteria in a septic tank primarily come from human intestinal bacteria in the feces. Only anaerobic bacteria from the feces survive in the tank. They are very inefficient and do little more than liquify some of the particles in the waste. Proteins can be broken down into ammonia but do very little. You can buy bacterial spores in the hardware that people add to septic tanks, but they need oxygen to germinate, so they are a waste of money.

Maintaining a Septic Tank 

Septic tanks require regular maintenance to function correctly. It is recommended that tanks are pumped every 3-5 years or so, depending on their load. Some people only pump once the system fails, then they have to since the liquid is backing up into the house. It’s also essential not to put things like Handi-Wipes into the tank, as they can clog pipes going out.

Why Do Septic Systems Fail? 

The primary reason for septic system failure is mucus accumulation over time, called “biomat” failure. If you do not pump your tank as often as you need, the scum and sludge layers get thicker and thicker. The liquid layer between them disappears, and septic solids like toilet paper and feces go out and clog lines, soil, and distribution boxes. Homeowners must also be careful not to rinse paint from working on the house or use excessive amounts of chlorine that can kill the tank.

Signs Your Septic System is Failing 

The earliest sign of a failing septic system is often evidence of green, lush grass over the leach trenches when the rest of the lawn is drier. The next sign is when you open a tank and see the liquid level in the tank higher than the bottom of the pipe that leaves the tank. Sometimes you will see seepage coming up into the yard. The ultimate clue is when your plumbing backs up into the house.

The Solution: SludgeHammer®

SludgeHammer® is a unique solution to fix failed leach systems without digging and replacing them, which can be a disaster in mature landscaping. SludgeHammer®’s use of biology to fix a biological problem makes it different and better. It works quietly inside the tank using air from a blower, making it a noise-free solution. Unlike other solutions, no heavy equipment is used, which means no damage to the landscaping. In addition, SludgeHammer® eliminates the odors in the septic system, making it no longer a “septic” tank. The bacteria recover and protect the leachfield soil, much like an insurance policy, and the liquid quality improves significantly. The liquid can even be recovered with irrigation systems like sub-surface drip, which both waters and fertilizes landscape vegetation, making it a valuable commodity. Overall, SludgeHammer® is a unique and effective solution that provides a better alternative to traditional septic solutions.

Many cottages near Northern Michigan’s beautiful lakes were built 50-100 years ago with sub-par wastewater systems. Septic tanks were often placed near the shore so that sewage would flow by gravity, with the liquid portion flowing downhill to a leach trench beside the lake. While this may have been acceptable when the cottages were only used during the summer, the situation has changed now that many properties have been developed and occupied year-round. Upgrading these systems to comply with current code requirements is problematic since most plots were laid out without any code in mind. The properties are often too small and too close to the water, with high groundwater levels that saturate their septic leachfields.

To upgrade systems on sensitive lots, the first step should be to improve the quality of the waste. The SludgeHammer advanced treatment technology was created to put natural bacteria, oxygen, and particles that filter out viruses and harmful bacteria into a septic tank to purify the wastewater before it reaches the leach field. This approach eliminates the need for excessive demands placed by current code requirements to keep the environment safe when untreated septic waste is being dumped into tiny properties.

To complement the SludgeHammer systems, Subsurface Drip technology is another solution to upgrade wastewater systems around lakes. This technology uses a drip tubing about 6 inches deep with emitters every 1 or 2 feet, slowly moving water through the soil by capillary flow. A pump sends out the water through a supply line, and a return line is brought back to the pump tank, with a series of individual drip lines connecting the two to create a drip field. This technology ensures that the liquid is released in the zone of highest biological activity where the natural environment does the work to process the waste and purify it.

Around lakes, these systems have several advantages:

1.  Most old leachfields are deep, meaning there is less unsaturated soil for purification before it gets into the groundwater.
2. With drip technology, the tubing is near the soil’s surface, increasing the separation from groundwater.
   The waste is released in the zone of highest biological activity, where worms, fungi, insects, protozoans, and other living things process the waste to ensure no pathogenic bacteria or viruses survive.
3. The highly treated wastewater is an excellent lawn fertilizer, continuously supplying nitrogen and phosphorus to plants in low concentrations, preventing nutrient runoff into the lake that could cause algae blooms. Or as we call it, “fertigation.”
4. The system creates a beautiful landscape feature, protecting the shorefront ecology, increasing property value, and giving homeowners a sense of pride for doing nature a favor.

When properties have high groundwater, the system may need to be mounded slightly. However, this is still preferable to the obnoxious structures that so many cottages are forced to put in their front yards with conventional mounds. By upgrading their wastewater systems, homeowners can enhance their properties, protect the environment, and take pride in doing the right thing.

Thousands of years ago, the soil could naturally treat all the waste humans generated, but now with billions of people on the planet, this is no longer possible. However, soil still plays a critical role in cleaning up after us. Over a century ago, the septic tank was invented to separate liquid waste from solids, but the soil’s final destination remains.

Soil comprises trillions of sand grains with a slight charge, which pulls the liquid through them via capillary flow. This flow allows trillions of bacteria to coat the grains and use oxygen to digest organic matter and purify waste. Soil particles also filter to keep pathogenic bacteria and viruses from our well water.

Initially, septic tanks drained into simple pits in the ground, but over time, we realized these would clog due to slimy mucus in septic waste that coated the soil. An elongated trough shape with a perforated pipe over a bed of drain rock was found to create more soil surface area for the liquid waste to drain. The rocks allow bacteria to colonize and digest waste, and the spaces between them give the liquid time to soak into the surrounding soil before the next load comes in.

Septic waste is full of dissolved organic matter, including mucus. Mucus is sticky and can clog the gaps in the soil grains, leading to leachfield failure. Several years ago, a company created a plastic chamber system with louvers to allow liquid to enter the soil. The design makes a large volume for liquid storage and is light and easy to install. However, claims that this technology could reduce the leaching system’s footprint needed to be more credible.

One of the arguments against using drain rock in the trench is that it blinds the soil absorption surface, but this is not true. The water flows around the rock and gets absorbed by the soil, and the bottom of any leach trench is usually sealed off by mucus in septic effluent in the first couple of years. The chambers are empty, so the soil at the bottom is exposed to stirring by the applied water, which mobilizes the fine particles and creates a seal at the soil’s surface.

Gophers can also be a problem in California, where they can fill an entire leachfield with soil. Sonoma County requires at least 6” of drain rock in a chamber system to combat this.

While the chamber systems do work, they should not get special credit. If they are half the size they need, they may require remediation with a SludgeHammer. Luckily, this method does work. Remember, it’s essential to properly maintain and care for your septic system to avoid any potential problems down the line.

Bacteria are the least understood and least appreciated organisms on earth. Humans seem to have an excessive fear of these little guys, but in many respects, we are just giant cargo ships for the thousands of species of bacteria that live in intimate association with us. Hundreds of different types coat our outer skin, and our insides also carry over a thousand species that do all kinds of jobs to keep us healthy. For us, the trick is to ensure that we have plenty of the “good” bacteria in and on us. These species are the best defense we have against the few organisms out there that are dangerous.

It is no accident that taking a course of antibiotics can disrupt our intestines. The antibiotics kill off the good guys as they go after the bad. Sometimes you can get pretty bad infections, and there is no choice but to use antibiotics, but our society has gone over the top with its obsession with cleanliness. “Anti-Bacterial” is omnipresent in our various cleaning products. But we must be much more cautious about how we use these products.

Our waste is full of bacteria, so naturally, a sewer line or septic tank will also be full of them. And, of course, we use bacteria to treat that waste. But when we consider the types of bacteria in the waste, it becomes pretty clear that virtually none of them are the type of organism that would be suited to “treating” waste. They are intestinal bacteria, and when you think about where they live inside warm-blooded animals, you realize they have some adaptations that make them probably the least suited for wastewater treatment.

First, any bacteria in our gut has spent its entire existence at 98.6o F. When they hit the toilet as your feces, they go into temperature shock. These bacteria can’t operate at average ambient temperatures. Second, these bacteria have co-evolved with us. We give them a warm home, and the bacteria pre-digest our food for us in exchange. They break large chunks into smaller molecules we can absorb through our intestines. But in a waste treatment system, we want bacteria to digest the organic waste down to CO2 so it can escape as a gas. If they did that in your gut, not only would they be stealing your food, but you would also be in constant pain from the gas. So, these bacteria have evolved delicate appetites, and we can keep them on board. Again, you want something else in a sewage digester.

Finally, gut bacteria live in a soup of enzymes and acids, so they must secrete a mucus coating to protect their cell membrane. All bacteria do this, but gut bacteria secrete a lot. This mucus is a problem. It makes everything slimy. It goes out into the septic tank and the soil, clogging the pores. Over time the leach trench can no longer soak away the effluent, and it comes to the surface right in your back or front yard.

But some bacteria can digest our wastes. Most of them live in the soil. After all, the soil receives billions of tons of dead material every year in the form of leaves, grass, animal bodies, you name it. These bacteria have big appetites, especially in temperate zones. Think of what happens in the forest. Each year during the summer, huge quantities of plant materials accumulate. The leaves fall to the ground and then are covered by snow. Nothing happens all winter, but as soon as spring and the snow melt moisten the soil, spores of bacteria start to germinate. What happens is a race. The first ones to emerge get a head start. They grow by dividing, and many of these species will divide every 30 minutes. The object is to eat as much as possible, reproduce, use up the food and then create a spore to wait for the following year. The bacteria that do this the fastest win the evolutionary race.

But there is another feature in the ecology of these organisms. They need oxygen and typically get it from O2 in the air. But in the leaf litter, you will get pockets that occasionally are anaerobic, like a bunch of soaked leaves packed together. This is a problem for “strict” aerobes that can only use O2 from the air. But many species of soil bacteria are “facultative” species. They grow fast with O2, but if that’s not available, they can get oxygen from other compounds that have oxygen in their makeup, especially sugar molecules. The cellulose of the leaves is a long-chain sugar, but so is the mucus that causes problems in leach fields. They do this using the process of fermentation.

Fermentation is more efficient than anaerobic digestion, but still, half the carbons get converted to CO2, and the rest become alcohols or esters, which are small molecules. The slimy, long-chain mucus molecules disappear, and clogged soil opens up.

We created the SludgeHammer to grow some of the best of these soil species inside a septic tank. If you just add aerobic bacterial spores to the tank, the bacteria go into the anaerobic septic tank and never even germinate.

With the SludgeHammer, we provide the oxygen these spores need to develop. We also designed it to use the air to mix and pump the liquid in the septic tank through the ABG column. The interior was engineered with fixed film media to provide a place for the bacteria to attach and form a colony. The liquid entering the SludgeHammer transports with it the food that the bacteria need, and, voila, the bacteria can grow in a septic tank.

Now we can send these bacteria out into the soil and clear out the clog, no mess, no fuss—just biology working for us instead of against us.

What is aerobic treatment, and why does it matter? Let’s begin with some history of septic tanks and wastewater treatment. When the clean water act was passed in 1970, the EPA said that by 2000 there would be no more septic tanks in the US. Sewers would be everywhere, and only the most remote houses would have septics. At the time, approximately 25% of US households had septic tanks. In 1998 congress asked EPA, “Hey, how are we doing on the elimination of septic tanks?” It turned out that now 27% were on septic. What happened?

It turns out sewer systems are extraordinarily expensive and only make sense in the densest cities. People kept moving to the suburbs, and we ran out of money for sewer systems. So the EPA had to accept that “onsite” systems would remain part of our permanent wastewater infrastructure. But the dilemma was that “onsite” was still just anaerobic septic systems, and now there were too many, and pollution was starting to crop up.

The engineering community had already developed elaborate technology to deal with city pollution. Wastewater treatment plants produced water that a city’s mayor would proudly drink in public. And now, with the EPA’s admission about “onsite,” the need for improving this technology created a marketplace. Engineers shifted their vision and tried to figure out how to create mini-treatment plants that could fit in a backyard.

The common strain through this technology is air. Septic tanks don’t get aerated, so there is no oxygen. Without oxygen, you get very little digestion of the organic wastes. After all, in the ocean, algae fall to the bottom where there is no air and last for literally 100’s millions of years, eventually becoming petroleum. Digestion is a form of a controlled burn. Our enzymes add oxygen to carbon compounds like sugar, protein, or fat and combine it to get carbon dioxide, releasing energy in the process. Real wastewater treatment started when sewers collected waste and sent them to ponds. Then various types of aeration devices were used to mix air into the water. If you made the pond big enough so that the organic waste stayed in the pond for several days, it would give time for bacteria to use the oxygen to digest the waste. Eventually, the ponds were modified into tanks made of concrete so more technology could be added, like filters, pumps, settling tanks, digesters, etc. Now, most wastewater treatment plants (WWTP) are sophisticated engineering systems requiring trained personnel to operate and large budgets.

The first generation of homeowner systems largely tried to copy the municipal WWTPs in miniature form. This meant specially designed tanks and various pieces of hardware that were offered as specific proprietary designs exclusive to the various manufacturers. Often these included the original septic tanks to act as a means to reduce the strength of the waste. This meant that those tanks still needed to be pumped on a regular basis. The National Sanitation Foundation (NSF) created its Standard 40 to test these devices so regulators would have confidence in allowing them to be installed in their jurisdictions. Now there are hundreds of these systems available to the public.

We took a different approach for the SludgeHammer. We created a portable device that acts as a bioreactor and can be placed inside a standard septic tank. Condensing tremendous treatment power is such a device it means we can convert most of the existing tens of millions of septic tanks into advanced aerobic systems without any infrastructure change at all.
