Small sewage treatment plants are the reliable solution for properties without connection to the public sewer system. They efficiently, sustainably, and legally treat domestic wastewater – up to 8.0 m³ daily. Modern systems combine biological processes with intelligent control, allowing for maximum purification performance with minimal maintenance effort.
With the systems EcoBox, RoClean and RoOxy, ROTO offers a modular product range for new construction.
ROTO wastewater treatment technology solutions for every installation situation:
- Modular solutions for new construction
- Compliance with all regulatory requirements
- Sustainable and energy-efficient technologies
- Flexibly adaptable to different plots
SBR wastewaster treatment plants (Sequencing Batch Reactor)
SBR wastewater treatment plants offer precise, time-controlled wastewater treatment with high effluent quality. The process operates in clearly defined phases – filling, aeration, settling, and discharge of treated water – thus enabling particularly efficient biological treatment.
Systems like EcoBox and RoClean are ideal for typical applications in single-family and multi-family homes. They impress with their compact design, reliable technology, and low maintenance requirements.
Typical areas of application:
Standard applications without special load fluctuations
New construction or replacement of existing systems
Plots of land with clearly defined requirements
4 - 8 PU
Space-saving SBR sewage treatment plant for single-family homes. Reliable and ideal for standard applications with stable cleaning performance.
4 - 50 PU
Proven SBR system with robust technology and high effluent quality. Suitable for continuous use with a consistent wastewater load.
SBR with oxygen optimization (aeration systems)
These systems are based on the proven SBR process, but they enhance it through optimized oxygen supply. Targeted aeration significantly improves biological degradation, leading to more stable processes and higher purification performance.
The RoOxy plant is specifically designed for more demanding conditions – for example, with higher loads or stricter effluent values.
Typical areas of application:
- Increased requirements for cleaning performance
- Fluctuating loads
- Optimization of existing SBR systems
4 - 8 PU
SBR small sewage treatment plant with optimized oxygen supply. Higher cleaning performance and process stability under more demanding conditions.
MBBR small sewage treatment plants (Moving Bed Biofilm Reactor)
MBBR systems rely on moving carrier materials on which microorganisms settle. These biofilms ensure particularly stable and robust wastewater treatment – regardless of load fluctuations.
The MBBR box is particularly suitable for applications where conventional systems reach their limits or a high process reliability is required.
Typical areas of application:
- Irregular use (e.g., holiday homes)
- Strongly fluctuating wastewater volumes
- High requirements for process stability
4 - 8 EW
Moderne Biofilm-Kleinkläranlage für max. Stabilität. Ideal bei schwankender Nutzung und erhöhten Anforderungen an die Abwasserbehandlung.

FAQ
What is a small wastewater treatment plant and when is it needed?
A small sewage treatment plant treats domestic wastewater in a decentralized manner. It is used when a connection to the public sewer system is not possible or economically sensible.
Which plant is the right one for my property?
That depends on factors such as population, soil conditions, and regulatory requirements. SBR systems (e.g., EcoBox, RoClean) are suitable for standard applications, MBBR systems for fluctuating loads.
Can I retrofit an existing pit?
Yes. Existing systems can be efficiently modernized with technology kits such as RoKit, RoOxy-Kit, or MBBR-KitRoKit.
How maintenance-intensive are the systems?
All systems are designed for minimal maintenance effort. However, regular inspections by qualified personnel are legally required.
