AQUATO STABI-KOM

Your Fully Biological Small Sewage Works

The AQUATO® STABI-KOM: Reliable wastewater treatment without odors and with minimal operating costs. The modern and sustainable alternative to sewer connection for your single-family home, vacation home, or new construction.

Three advantages that make the difference.

Reliably odor-free

The intelligent SSB® process actively prevents putrefaction processes. This not only protects your nose, but also concrete containers from corrosion.

Extremely economical

Benefit from energy-efficient technology that only works when needed, and from long intervals for sludge removal.

Designed for decades

Rely on robust quality "Made in Germany". Our plants are designed for a long service life and high operational reliability.

How the SSB® process works.

The key to the efficiency of the STABI-KOM lies in the SSB® process: All treatment stages take place in a single, compact container. The result is maximum treatment performance with minimal effort.

Aeration Phase

Your wastewater is supplied with oxygen in a targeted manner. Billions of microorganisms immediately begin the biological degradation of pollutants.

Settling Phase

Aeration stops. The activated sludge settles and a zone of crystal-clear water forms on the surface.

Discharge Phase

The treated water is gently pumped out. The treatment cycle begins again – intelligently and fully automatically.

Certified performance that redefines standards.

The effectiveness of the SSB® process is certified in accordance with DIN EN 12566-3. Our plants significantly exceed legal requirements. For you, this means: demonstrably clean water and the certainty of having made a future-proof decision. This is how technical superiority becomes a direct financial advantage.

STABI-KOM: The flexible small sewage works.

The STABI-KOM is a well-designed complete system. Its flexibility is created through the targeted selection of high-quality components that perfectly match your property and situation. Discover the building blocks that make your plant reliable and simple.

Complete Plant Concrete (BM-03)

The most robust solution for new construction. Solid, manufactured in one piece and extremely durable. Due to its high dead weight, the container is absolutely buoyancy-proof and the first choice for maximum stability on standard properties.

Complete Plant Plastic (KL-02)

The lightweight and flexible solution. Ideal for properties that are difficult to access, the plastic container enables easier transport and faster, time-saving installation, without compromising on tightness and durability.

The Retrofit Kit

The clever option for modernization. Do you already have a sealed three-chamber cesspit? Perfect. With our flexible retrofit kit, we turn your old cesspit into the heart of a modern STABI-KOM. This is the most cost-effective and fastest solution to bring your plant up to the latest state of technology.

Control & Connectivity

Intelligent as standard: The K-PILOT 2.4 controls operation fully automatically and energy-optimized. Via Wi-Fi Direct, you can conveniently access it and effortlessly keep the software up to date through wireless updates.

Smart extension (optional): Make your plant IoT-capable with ProConnect. The extension enables full remote access via app and cost-saving remote maintenance by your service partner.

Frequently Asked Questions

Here you will find answers to the most important questions asked by builders and homeowners.


The total costs are individual. However, the STABI-KOM is designed for maximum economic efficiency over its entire service life. Through very low power consumption and infrequent sludge removal, you save year after year. Request an individual offer to receive an accurate cost estimate.


Power consumption is extremely low, as the energy-efficient compressor only runs when needed. In operation, the plant is practically inaudible, as all technology operates sound-insulated underground.


Maintenance intervals are legally regulated. Thanks to robust technology and optional remote monitoring with ProConnect, the number of on-site maintenance visits can potentially be reduced to just one per year, depending on official approval.


We rely on quality "Made in Germany". In particular, the monolithic concrete containers have an expected service life of several decades. A STABI-KOM is a safe and sustainable investment in your property.


Yes, in many cases retrofitting your existing three-chamber cesspit is possible. Our flexible retrofit kits can often be integrated into existing, sealed containers, which represents a cost-effective alternative to new construction.
