Rainwater Harvesting Systems
Sanirain: rainwater managers for efficient and safe non-potable water supply.
With Sanirain, SFA Export offers solutions for the use of rainwater in buildings.
These rainwater managers enable non-potable water supply to installations such as toilet, washing machines, or water points for irrigation and floor cleaning.
In case of an empty supply tank, the system automatically switches to the drinking water network, ensuring continuity of service.
Thanks to their ease of installation and automated operation, Sanirain devices not only ensure optimal management of rainwater but also complete disconnection between the drinking water network and the non-potable water network, in order to comply with health standards (EN 1717).
Frequently Asked Questions
A rainwater harvesting system collects and manages rainwater so it can be reused for non-potable applications. Sanirain systems are designed to supply toilets, washing machines, irrigation points and floor-cleaning outlets with harvested rainwater.
Sanirain is an automated rainwater management system designed for domestic use. It uses an electronic control system to manage the available rainwater and maintain a constant water supply pressure for non-potable applications.
No. Rainwater is non-potable and must not be used for drinking, cooking, personal hygiene or any other application requiring potable water. Sanirain is designed for clearly defined non-potable uses such as toilet flushing, washing machines and irrigation.
The SFA Export range includes the Sanirain 4 and the Sanirain 6. The Sanirain 4 is supplied with the SaniMHP 4-40 pump, while the Sanirain 6 is supplied with the SaniMHP 6-50 pump. Both are automated rainwater management systems for clear water and rainwater.
Sanirain systems are designed for easy installation and automated operation. The system is supplied with a compatible pump, electronic controls and the components required for rainwater management. Installation must be carried out according to the product manual and local regulations.
Regularly check the rainwater tank, pipe connections, filters and control components. The system should be maintained according to the instructions provided in the product manual. Any malfunction, leak or abnormal noise should be investigated promptly by a qualified professional.
Harvested rainwater can be used for non-potable applications such as flushing toilets, supplying washing machines, watering gardens, irrigation, fountains and cleaning floors. It must not be used for drinking, cooking or other applications requiring potable water.
When the rainwater tank is empty, the Sanirain system automatically switches to the drinking water network. This ensures continuity of service for the connected non-potable installations.
Sanirain provides complete disconnection between the drinking water network and the non-potable water network. This helps prevent cross-contamination and supports compliance with the EN 1717 standard for the protection of drinking water supplies.
The main difference is their hydraulic performance and recommended installation capacity. The Sanirain 4 has a maximum flow rate of 4 m³/h and is suitable for automatic operation up to a lifting height of 12 metres. The Sanirain 6 has a maximum flow rate of 5.2 m³/h and is suitable for automatic operation up to a lifting height of 20 metres. The choice depends on the required flow rate, lifting height and number of connected applications.
The right system depends on the size of the rainwater tank, the number and type of connected applications, the required flow rate, the lifting height and the expected frequency of use. The Sanirain 4 is suitable for lower-demand installations, while the Sanirain 6 is designed for higher flow requirements and greater lifting heights. For complex projects, contact an SFA Export partner or a qualified professional.
Yes. Sanirain systems are designed for domestic use and can supply non-potable water to applications such as toilets, washing machines, irrigation points and floor-cleaning outlets. The system must be correctly sized and installed according to the building’s requirements.
