Reference: Retrofit of the fountain system at the station square in Bad Saarow
Bad Saarow station square is known for Hans Eickworth's "Lebensfreude" fountain and its well-tended green spaces. An innovative solution was required for efficient irrigation and reliable system monitoring in order to increase the availability of the system and make everyday work easier for the office staff.

Problem definition
In the past, heavy rainfall and overflowing cisterns or blocked pumps repeatedly led to defects. Officials had to be on site regularly to identify problems or only respond when damage had already occurred. This was time-consuming and led to longer downtimes.
Solution approach & implementation
We developed a customized system that makes monitoring and controlling the plant more efficient:
- Cistern monitoring: Ultrasonic sensors continuously measure the fill levels of the cisterns. The maintenance-free sensors enable precise and flexible setting of the limit values.
- Pump protection: A current monitoring relay ensures the safety of the deep well pump by reacting to underload or overload, phase failures and other faults.
- Remote control and alarms: A Siemens S7-1200 controller processes the measurement data, controls pumps and valves, and sends alarm and status emails via a secure connection (TLS). Office staff can conveniently query the system status remotely and adjust parameters such as limit levels or operating times.
Results at a glance
The Office Scharmützelsee now benefits from a reliable and robust solution that sustainably improves the operation of the irrigation system. Faults are detected and reported immediately so that targeted measures can be taken. Time-consuming on-site inspections are no longer necessary, and the office staff can keep an eye on the system status at all times.
- Reduced maintenance effort: remote monitoring replaces time-consuming on-site inspections.
- Fast response times: Automatic alarm messages provide direct information in the event of faults or malfunctions.
- Maximum system availability: Robust and reliable measuring systems minimize downtimes.
- Flexibility and customizability: Freely parameterizable limit levels and operating parameters.
- System protection thanks to state-of-the-art technology: monitoring of the deep well pump protects against damage caused by overload, blockages or pump idling.
- Cost-effective communication: Alarm and status messages by e-mail minimize additional infrastructure costs and ensure an efficient flow of information.
