Designed for systems with smaller openings & access, the SludgeHammer® S-66 restores failing leach fields, offering a reliable, cost-effective way to extend the life of aging or damaged septic systems. It helps homeowners avoid the high cost of replacing the entire system by improving the performance of the existing leach field. See Specifications for dimension details.
Engineered for homes with up to four bedrooms and narrow septic tank access (≤9” opening), the SludgeHammer® S-66 Slim ABG offers an environmentally responsible solution for restoring and preserving septic system health. Designed to retrofit easily into existing infrastructure, it revitalizes failing leach fields, extends the life of new systems, and minimizes environmental disturbance—all without costly excavation or landscaping reconstruction.
At the heart of this system is the SludgeHammer Blend™—a scientifically advanced consortium of oxygen-loving bacteria that amplify organic waste digestion and manage clog-forming biomat. By maintaining aerobic conditions in the septic environment, the S-66 Slim ABG supports natural soil absorption and long-term groundwater protection. Certified under IAPMO IGC180-2003 and recognized by the Uniform Plumbing Code, SludgeHammer technology restores system function up to 4x faster than aerobic treatment alone.
The result: Reduced waste pumping, maximized environmental protection, and a future-ready, biologically regenerative approach to residential wastewater and disposal field management.
Designed for homes with up to 4 bedrooms, effectively restoring failing leach fields and proactively protecting existing septic systems.
The SludgeHammer Blend™ revolutionizes residential septic system function. Soil absorbs waste through microbes in the ground that consume organic material. The microbes thrive in oxygen-rich environments. Without oxygen, something called biomat is produced — a slime that clogs the soil. Clogged soil causes residential septic systems to fail, which means they can no longer treat the wastewater produced by your household.
It is estimated that 95% of all septic system failures are caused by biomat clogging. SludgeHammer® technology is rigorously tested and certified to restore leach systems clogged by organic biomat at a rate of at least 2.5 times that of aerobic treatment alone through testing under IAPMO IGC180-2003. SludgeHammer® is the ONLY technology on the market that holds the IAPMO standard.
Eliminate biomat clogging and optimize septic function with the SludgeHammer® S-66. Instead of rebuilding an entire septic system, installing a SludgeHammer® unit allows homeowners to rehabilitate their septic systems at minimal cost.

SludgeHammer® Warranty
Meeting environmental and health standards in wastewater treatment is a necessity for public safety. Certified systems protect soil, groundwater, and ecosystems. Partner with SludgeHammer® to offer trusted products and help create a healthier environment.
This case study highlights a septic system upgrade in Coloma, Michigan, where a high water table caused system failure. The site presented three major challenges: limited space for installation, a water level near the surface, and a small lot that couldn’t support traditional systems. These issues made a standard septic solution unworkable.
To overcome these challenges, the SludgeHammer® septic system was installed. This system uses air and bacteria to clean effluent inside the septic tank, allowing for smaller pipes, drip irrigation, and eliminating the need for stone or sand. It also enabled a smaller, less intrusive mound, approved by the health department.

SludgeHammer® systems have been rigorously tested and certified by the industry’s most elite organizations. We offer a limited lifetime warranty on all technology; however, guarantees cannot be made as we’re unable to control actual daily flows. If harmful substances are introduced to the system or if annual maintenance needs are neglected, issues can arise.
Each SludgeHammer® ABG will take approximately 2-3 hours to install.
Once installation is complete, you can expect the system to fully acclimate within 36 to 72 hours.
Provided you’re using your SludgeHammer® system within its design parameters and maintaining it in accordance with the manufacturer’s recommendations, your system should last indefinitely.
As with any septic system, common knowledge is key. Do not rinse or flush paint into the septic tank, don’t flush handi-wipes or non-degradable materials (including tampons) down the toilet, and ensure cleaning products such as bleach are used in small quantities.
Yes, all systems, including conventional septic systems, require consistent maintenance. SludgeHammer® systems should be maintained annually for residential systems and multi-annually for non-residential systems.
Yes, the bacteria is safe. However, avoiding contact with the eyes and handwashing are always recommended practices when handling any bacteria.
