Product information " Greywater recycling plant GWI 15.2-15.000 (capacity 15,000 l/day)"
This system can treat up to 15,000 liters of graywater per day.
The GWI 15.2 – 15,000 graywater recycling system is a high-performance large-scale system for treating graywater from showers, bathtubs, and handwashing sinks. It is suitable for neighborhood solutions, large-scale residential and commercial areas, as well as industrial and special applications with very high graywater volumes.
Through a combination of biological treatment and modern ultrafiltration (membrane filters), graywater is reliably purified, made usable as process water, and specifically applied where drinking water quality is not required—e.g., for irrigation, cleaning purposes, or toilet flushing. When operated properly, the treated water meets the quality standards of the EU Bathing Water Directive for industrial water applications.
The system actively contributes to saving drinking water and supports sustainable water management in large residential and commercial areas as well as in public and industrial applications.
Our greywater systems are configured on a project-specific basis and adapted to the respective structural and technical requirements. The configuration listed here therefore represents an example of a typical design. Variations in the type, number, and design of the components are possible depending on the project.
The delivery time for the system is approximately 4–6 weeks.
Functionality & Technology
The overall purification process consists of biological treatment and ultrafiltration. The treated water is then stored in the service or clear water tank.
The BioMembrane filter technology used ensures the separation of biomass from the graywater through its barrier effect and guarantees a very high hygienic quality of the clear water.
The system consists of several coordinated components:
- Sedimentation tank for pre-treatment
- Aeration tank for biological treatment
- Filtration unit with an ultrafiltration membrane that retains the finest particles, germs, and bacteria
- Service water tank for storing the treated water
The entire graywater treatment process is fully automated via an integrated control system. If there is insufficient process water available, standard-compliant drinking water is added to ensure a reliable supply at all times. After power outages, the system automatically resumes operation.
Applications
The GWI 15.2 – 15,000 graywater treatment system is designed for:
- Neighborhood and site solutions
- Large residential and commercial complexes
- Hotels and vacation resorts with high occupancy rates
- Hospitals, administrative centers, and large school complexes
- Industrial and special applications
It enables a significant reduction in drinking water consumption and actively contributes to sustainable water management and lower operating costs.
Installation
- Indoor system, intended for installation in utility rooms.
- Installation, commissioning, and maintenance must be performed exclusively by qualified personnel.
- Separate piping required for greywater and process water.
- Pipes must be clearly marked in accordance with applicable standards.
- The treated water must not be connected to the drinking water supply.
The system must be installed and operated in accordance with applicable technical regulations (including DIN standards and the Drinking Water Ordinance). Service water systems must generally be reported to the responsible public health department.
Maintenance & Operation
- Annual maintenance by qualified personnel is required.
- Regular visual and functional inspections by the operator are recommended.
- Maintenance and inspections must be documented in the operating log.
Proper operation ensures a long service life, high operational reliability, and consistently high water quality. By adhering to the manufacturer’s specifications and handling the system responsibly, the system also impresses with exceptionally low maintenance requirements.
Advantages at a Glance
- Sustainable reuse of greywater.
- Modern ultrafiltration for high water quality.
- Durable components ensure long-term stable, high-quality process water when operated properly.
- Fully automatic, reliable operation.
- Reduction in drinking water consumption and costs.
- Suitable for neighborhood solutions, large-scale residential and commercial areas, and industrial applications.
- Supply reliability through automatic replenishment.
Additional features & notes
- The system is designed for the treatment of domestic graywater (e.g., shower, bathtub, hand basin).
- Kitchen wastewater, sewage, or heavily contaminated wastewater must not be introduced (see instructions).
- The treated water is to be used exclusively as service water (not drinking water).
- During prolonged absences, the system should remain switched on to maintain biological function.
- Proper planning of the greywater piping is essential for trouble-free operation.
- Modifications to the system or control unit may only be performed by authorized qualified personnel.

DetailsThe E.sybox – your smart solution for boosting water pressure in the home. The E.sybox requires no additional components for installation. It consists of a self-priming multistage pump, an electronic inverter for speed control, flow and pressure sensors, a high-resolution rotatable LCD display, and integrated 2-liter expansion tanks. The E.sybox can be installed both vertically and horizontally. It can also be installed in tight, poorly ventilated spaces. The water-cooled motor, the ABS housing with sound-absorbing properties, the vibration-damping feet, and the electronics make it quiet (45 dB) and compact.
DetailsDevice for refilling the cistern with drinking water. When the water level in the rainwater cistern, the basement tank, or the service water tank of a graywater recycling system drops, a solenoid valve is opened via the float switch and drinking water is added.
