No electronics in the wastewater
The SSB® process works with compressed air: inside the tank there are no pumps, no motors and no moving parts. The technology stays dry at the edge of the plant, where it is easy to reach.
Mid-range · 4-50 PE
AQUATO's best-selling small plant in Germany: fully biological, chemical-free and with no moving parts in the water. The long-lasting solution for houses, multi-unit buildings and small housing developments.
Three strengths
The SSB® process works with compressed air: inside the tank there are no pumps, no motors and no moving parts. The technology stays dry at the edge of the plant, where it is easy to reach.
Only aerobically stabilised sludge is produced, and its removal can be put off for years. This noticeably reduces running costs, with long-term reliability.
It treats water without chemical additives and keeps performing even when the house stands empty for a season. The worry-free option for places used seasonally.
In practice
Delivery, crane lift and installation of a STABI-KOM concrete tank on site. The plants shown are in the range of 4 to 12 PE, for single-family and multi-family homes. German AQUATO technology in real use.
How it works
What is included
The technology arrives pre-assembled in the tank. It is placed, connected and the K-PILOT control unit is switched on: depending on size, the plant is installed in one to three days.
The airlifts move the water between chambers using compressed air only, with no pumps in the wastewater.
Introduces the air as fine bubbles for the biological stage. Other aerator shapes are available depending on the tank.
Produces the compressed air for the whole process, sized according to the population equivalents.
The plant's control unit, installed in a dry place outside the tank. You simply plug it in: it runs the cycles and reports faults. After a power cut it restarts on its own.
No electronics in the water. No chemicals in the cycle.
Robust technology that protects water and soil, year after year.
Technical data
The STABI-KOM covers the range from a single-family home to a small housing development. The final values depend on the project; we review them with you during the consultation. The energy figure refers to the CE-certified reference size; for larger sizes we state it per project. All models are housed in robust polyethylene tanks with a walk-on cover rated up to 200 kg; up to 8 PE one tank is enough (up to 6 PE about 4.9 m³, at 8 PE about 6.4 m³ of usable volume), and larger plants have several. As a complete plant, the STABI-KOM carries the CE mark to EN 12566-3.
Tanks
Up to 6 PE, the walk-on KL-02 plastic tank is used (installation depth 1.75 to 2.05 m). From 8 PE the standard is the larger KL-06 with 6,500 litres (installation depth 2.52 to 2.72 m): one tank at 8 PE, two from 10 to 16 PE. Larger plants are sized per project, from 27 PE with the elongated high-volume KL-09 tank. Alternatively, AQUATO supplies the complete plant in a BM-03 concrete tank. If the tank is built in concrete on site, a local construction company builds it following AQUATO's drawings; the technology, the drawings and the coordination with that company go through us. Because it is built on site, this option needs a little more planning time. The delivered plastic tank comes with up to 25 years of manufacturer's warranty. The material warranty is based on our statistics and tests, see the Installation and Operating Manual.
Purchase options
The technology comes from Germany. For the tank there are two routes, which we recommend depending on location and budget.
Option A
The tanks with built-in SSB® technology arrive from AQUATO configured and factory-tested. The compressor and control unit sit dry outside the tank, so there are no electronics in the wastewater. On site, all that remains is excavation, placement and connection.
Why we recommend it:
In most projects, the delivered plastic tank works out cheaper than a concrete tank built on site, and it is installed much faster.
The tank arrives watertight and factory-tested, with up to 25 years' manufacturer's warranty.
What you receive:
Option B · Alternative
The SSB® technology, compressor and control unit come from the AQUATO factory. Your local partner builds the tank in concrete according to the AQUATO plan (dimensions, reinforcement, connections).
When it makes sense:
Only when the project requires it, for example for very large volumes or when concrete construction is taking place on site anyway. In most cases, the delivered plastic option is more economical.
What you receive:
The STABI-KOM has no technology inside the wastewater; only the tank is bulky. Here the delivered plastic tank (Option A) is the most economical option.
During the consultation we recommend the right option for you. In most South American projects, the delivered plastic plant (Option A) is the most economical.
Spring special offer
German technology. Special price. Sea freight included.
STABI-KOM for 4 PE
PE stands for population equivalent: the wastewater one person produces per day. 4 PE is sized for 4 people, that is one household.
Regular price: €11,991 You save €491
€11,500
For 4 people that is €2,875 per person.
Special offer valid until 31 December 2026
Included in the price
A special opportunity to get the STABI-KOM, especially durable and with no electronics inside the wastewater, with a significant price advantage and sea freight included.
Several houses or cabins can share one plant, for example at a tourist resort or a hotel. Per unit, this is considerably cheaper than installing a separate plant for each one.

Choose the size. The smallest is our special price; the others are guide prices from the AQUATO 2026 catalogue.
From 37 people, the ORKA is usually the better choice.
With a concrete tank built on site, at this size it usually works out cheaper than a STABI-KOM with large plastic tanks. We calculate both options for your project.

approx. €11,500
For 4 people that is €2,875 per person.
Technology only: from 17 people, the PUMP goes into a concrete tank built on site.
Guide price including a sea freight flat rate of €1,200; for larger plants the freight may be higher. This is not a binding offer: we calculate the exact price for your project.
Applications
If you value a particularly long-lasting, low-maintenance plant, the STABI-KOM is the high-quality alternative to the PUMP. No technology in the wastewater and minimal sludge removal.
In lodges, cabins and small hotels with varying occupancy, the STABI-KOM keeps performing even when occupancy is low. For larger resorts we move up to the ORKA.
One shared STABI-KOM for several houses: you pay for the technology, installation and maintenance once, not for each house. No electronics in the wastewater, for 4 to 50 people.
First step
In the free consultation (30 to 45 minutes) we look at the location, the load and the ground, and recommend the right model size. We reply within two working days.
