Maintaining drinking water quality – the automated approach 

‘Keep the water flowing’ is a key principle within drinking water hygiene. As a building operator, this is why you have a legal duty to ensure the regular exchange of water across all tapping points. If usage is interrupted for longer than 72 hours, stagnation flushes must be performed to maintain drinking water quality and therefore ensure the specified normal operation of the installation. If flushes are carried out manually, however, this is a time- and labour-intensive process that is also costly, as it consumes a lot of water. SCHELL makes it both simpler and more efficient.

Highly convenient: central monitoring and control for stagnation flushes 

With the SWS Water Management System and the SMART.SWS cloud service, stagnation flushes can be triggered and monitored centrally: 

  • End-to-end networking: stagnation flushes are possible across all relevant tapping points within a building 
  • Scheduled or temperature-controlled triggering of stagnation flushes: with corresponding programming, SWS proactively controls the necessary stagnation flushes (e.g. if the cold water temperature is exceeded or fittings are used less often, e.g. during holidays)

Adjusting and monitoring stagnation flushes on site

How E² helps with stagnation flushes for wash basin faucets on site in smaller properties: 

  • Rapid, app-based configuration of stagnation flushes for wash basin faucets and faucet groups in Bluetooth® range 
  • Choice of scheduled flushes, cyclic flushes or smart demand-based flushing

Efficient stagnation flushes – your benefits at a glance: 

The SWS Water Management System with SMART.SWS is a recommended choice if you have a lot of fittings – including varying types – in larger or multiple properties. E² is the ideal solution for facility managers who need an on-site tool to configure and monitor stagnation flushes at wash basin faucets.

Tips for efficient facility and building management 

As a building operator, you need to ensure that your facility management team is deployed as efficiently as possible. Digital solutions like our water management system offer practical tools for handling tasks, while E² makes jobs much easier and therefore quicker to complete.

Remote control replaces in-person visits 

Thanks to SWS/SMART.SWS, the facility management team no longer needs to be on site for water management work. Instead, the cloud-based service can be used to keep track of all installations worldwide: 

  • Remote monitoring and maintenance 
    • Keep track of water consumption (calculated) for networked fittings and your normal operation status at all times 
    • SWS: the water management system that keeps the building’s drinking water installation running smoothly is managed centrally via the server 
    • SMART.SWS add-on: this cloud solution offers clear-cut management functions for any building, anywhere in the world 
  • Local deployments of maintenance teams can be planned predictively (such as battery replacement work, for example) 
  • SWS can also be integrated into the central building control system
SMART

For optimal building management: app significantly reduces local workloads 

E² is the on-site solution for time-saving, user-friendly building management in smaller properties: 

  • Bluetooth® inside: room-scale parameterisation and monitoring of wash basin faucets for specified normal operation 
  • Consumption (calculated) and triggerings at-a-glance locally 
  • Keep track of faucet status (e.g. battery levels) on site 
  • Predictive planning of maintenance work (such as battery replacements, for example) Create buildings and rooms in the app for building management 
  • App with many practical functions and presets, such as a group manager and predefined operating modes 
  • Group manager for efficient management of local faucet groups 
  • Settings such as cleaning stop (for example) easily changed in the app 
  • Easily access system records in the app

Helping facility managers to concentrate on their core activities 

SCHELL solutions help building operators deploy their employees from the facility management team efficiently – especially where hands-on work is literally needed. Easy upgrade path: you can always move to SWS/SMART.SWS if you find that the E² app-based solution is no longer meeting your needs as a building operator. All E² faucets can be integrated into either system.

Dokumentation_Reporting

End-to-end documentation: no-hassle fulfilment of reporting obligations 

As a building operator, enjoy the peace of mind that comes from knowing you always have proof of compliance with your legal obligations to maintain drinking water quality.

Easy access to system records from the user interface or dashboard 

The SWS Water Management System/SMART.SWS offers comprehensive record-keeping functionality: 

  • Parameters logged: triggerings, stagnation flushes, water consumption (calculated) 
  • Accessible from the user interface (SWS) or via the attractively presented dashboard visualisation (SMART.SWS) 
  • File export possible

App-based record-keeping 

E² also keeps activity logs that are just as extensive as those for the SWS Water Management System: 

  • records of triggerings, stagnation flushes, water consumption (calculated) 
  • Accessible from the app 
  • Can be exported

Giving building operators peace of mind for record-keeping 

Both SCHELL solutions keep records of activities that are similar in terms of scope. Building operators can therefore provide legal proof of compliance whenever they may need to.

The right way to save water: balancing hygiene against resource conservation 

Drinking water is essential to life and therefore a precious resource. However, stagnation flushes – which consume water – are needed for hygienic and health reasons. Accordingly, SCHELL’s SWS/SMART.SWS and E² solutions only use exactly as much water as is needed to ensure the hygienically safe operation of the drinking water installation. Fittings, faucets and stagnation flushes can also be adjusted to be as economical as possible. With E², for example, there is the special ‘Save water’ operating mode and the ‘smart demand-based flushing’ function.

Saving water with SWS/SMART.SWS 

  • Electronic, contactless fittings are an important part of SWS/SMART.SWS: they consume up to 70% less water compared with standard single-lever mixers and correspondingly require less energy for hot water heating
  • Saving water with optimised, automated stagnation flushes – scheduled or temperature-controlled 
  • Only the volume of water needed to maintain drinking water hygiene is exchanged – namely the volume of the drinking water installation – and this also only every 72 hours or according to usage and temperature

Saving water with E² 

  • Electronic, contactless E² faucets consume up to 70% less water compared with standard single-lever mixers and correspondingly require less energy for hot water heating
  • The pre-configured ‘Save water’ operating mode stops the flow of water even faster after the user exits the sensor area – thereby saving even more water
  • Saving water with optimised, automated stagnation flushes as scheduled flushes, cyclic flushes or smart demand-based flushing 
  • Smart demand-based flushing: Flushes are recalculated and executed daily, after allowing for usage levels
  • Flushing is skipped if usage levels are high enough This ensures compliance with the 72-hour rule (VDI 6023) while minimising water consumption

Saving water means cutting costs

SWS/SMART.SWS and E² make sure that water usage is kept to a minimum, which guarantees the sustainable, resource-friendly and likewise cost-effective operation of the drinking water installation.
