Smart rainwater storage control with GOcontroll Moduline systems helps cities manage runoff, prevent flooding, and reuse water efficiently.

Urban environments face growing challenges with rainfall management due to dense construction and limited natural infiltration. Rainwater storage control offers a practical, sustainable way to reduce sewer flooding and make better use of collected rainwater. GOcontroll’s Moduline platform provides the perfect balance between reliable control, flexible I/O, and intelligent monitoring—making it easy to automate pumps, valves, and sensors for advanced rainwater management systems.

In modern cities, rainfall can quickly overwhelm drainage networks. Hard surfaces like asphalt and concrete prevent natural infiltration, leading to water pooling or even flash flooding. By integrating rainwater infiltration and storage systems, municipalities can:

• Reduce peak water flow into sewers.

• Capture and store water for later use.

• Recharge groundwater through managed infiltration.

• Support sustainable irrigation in green zones.

However, these systems are only as effective as their control strategies. Automating storage and release processes ensures stability, safety, and efficiency during variable weather conditions.

GOcontroll’s Moduline Mini and Moduline IV embedded controllers are ideal for automating rainwater storage control systems. These rugged, modular controllers are built to handle outdoor and industrial conditions while offering precise digital control.

Key advantages include:

• Scalable I/O modules for readout or control of  pumps, sensors, and flow meters.

• CAN and Ethernet communication for distributed installations.

• Linux-based software compatible with Node-RED and MATLAB Simulink for intelligent control logic.

• Data logging and remote access through Wi-Fi or cellular connectivity.

This modular approach makes it possible to start small—controlling a single storage basin—and later expand to a city-wide, networked rainwater control system.

A GOcontroll-powered control system continuously collects data from:

• Rainfall sensors detecting incoming precipitation.

• Level sensors monitoring storage tank capacity.

• Soil moisture sensors assessing infiltration area saturation.

• Flow sensors tracking discharge or infiltration rates.

The controller uses this real-time data to regulate pumps and valves automatically. For instance, during heavy rain, it can redirect flow from infiltration basins to underground storage tanks. Once conditions improve, the same system can release stored water back into infiltration areas or reuse it for irrigation.

This dynamic balance between capture, infiltration, and reuse helps cities optimize stormwater without wasting valuable resources.

Rainwater management systems are typically installed outdoors—often underground, or in damp, harsh conditions. The Moduline embedded controllers are engineered for this reality:

• CNC-milled aluminium housing for mechanical strength.

• IP67 equivalent rated protection against water and dust.

• Pressure equilibrium vent to prevent internal condensation.

Its modularity make maintenance and future I/O changes simple, while built-in safety mechanisms such as supply voltage monitoring ensure long-term stability in demanding field applications.

With GOcontroll’s cloud-enabled architecture, engineers and municipalities can access live system data and historical performance remotely. Using Node-RED dashboards, operators can visualize water levels, rainfall trends, and valve activity in real time.

This digital layer enables:

• Predictive maintenance based on sensor data trends.

• Automatic alerts for overflow or pump failure.

• Optimized water reuse scheduling based on local forecasts.

Such intelligence transforms ordinary storage basins into smart water networks, ready for integration into broader urban water management systems.

As cities adapt to climate change, rainwater infiltration and storage control will play a vital role in sustainability strategies. GOcontroll’s Moduline controllers give engineers and municipalities the flexibility to automate, monitor, and expand their systems—without costly redesigns.

Whether managing a single retention pond or a district-wide network, GOcontroll provides the hardware and software foundation for smarter, greener cities that make every drop count.
