Data-driven sewer management at Euvelgunne business park

Based on measurements, sewage discharge is controlled. The algorithm determines whether a valve for the transit is open or closed. This makes it possible to control where this water goes during periods of high rainfall.

Responsible use

Goal and impact

Due to climate change, heavy showers are falling more frequently and this caused problems at the Euvelgunne business park, in south-east Groningen, among others. To counter these problems, several measures are being deployed. One of these measures is that, based on online measurements with sensors, the discharge of sewage is controlled. This should also prevent the need to dump sewage water into vulnerable ponds.

Considerations

By deploying data-driven sewer management, it is possible to reduce water nuisance for the Euvelgunne in a cheaper way than through other solutions. As a result, less polluted water enters vulnerable ponds. In addition, water treatment can do its job better.

The disadvantage is that slightly polluted water can enter the Winschoterdiep. However, this is within the limits of what is allowed.

Human intervention

The slide can also be operated outside the algorithm. In the management system/with telemetry, the slide can be operated by human intervention and can also be tracked when the slide opens or closes. The employee responsible for managing this type of facility will be notified as soon as the slide opens or closes.

Risk management

The Municipality of Groningen involved the water boards early on in this project. Before the system was implemented, a theoretical trial was conducted. Only after its results were positive was a practical trial done where water was actually drained.

Water quality is well monitored. There is also an online alarm of the sluices and the sluices are checked regularly. The management of these sluices falls under standard management.

Legal basis

The legal basis for this algorithm lies in the Environmental Management Act. This law broadly defines the legal means to protect the environment and the principles that govern it.

Operations

Data

The basis for data-driven sewer management is a set of computational rules. These are site-specific. With up-to-date data on precipitation, the remaining storage capacity in the sewer, the quality of the sewage and the

quality of the surface water in each part of the system, the calculation rules can be used to determine the most optimal discharge situation and when any sewage should be discharged to the outside water in a controlled way.

Technical design

The technical operation and the different parameters are explained in the report Data-Driven Sewer Management at Euvelgunne business park. It can be accessed via the link below.

External provider

This system was developed together with Waterlab Noord (WLN) by the Municipality of Groningen.

  • The algorithm uses sensor data to make a calculation for predictions of slipperiness risks. These predictions are used to determine where to grit (preventively), in consultation with meteorologists. In addition, the algorithm can issue various alarms, for example when there is a chance of wet road sections freezing.
