Stormwater Basin Analysis: Unlocking Potential Through Data-Driven Insights

Stormwater Basin Analysis: Unlocking Potential Through Data-Driven Insights

Stormwater basins have become a critical component of utility companies' climate adaptation strategies. Their performance can significantly impact both overflow incidents and the ecological health of nearby rivers and lakes. However, they often remain a hydraulic black box, making them somewhat difficult to predict. This is how we help utilities unlock the potential of their basins through data-driven insights.

Stormwater basins are an effective method for collecting rainwater, preventing it from mixing with wastewater and being discharged into our recipients. During heavy downpours, rainwater is directed to these basins, helping to prevent sewer systems from becoming overwhelmed during increasingly frequent and intense storms.

However, the effectiveness of these basins raises important questions:

bullet
Will the full capacity be available when it is needed ?
bullet
Do they work as expected ? Are they utilized ?
bullet
Is the residence time enough to ensure sedimentation of particles that should not be released ?
bullet
Do they become anoxic and overheat causing problems in the recipient ?
bullet
Are the outflow-permits being utilized ?

These are just a few of the critical questions that many utility companies face.

Many stormwater basins were constructed years ago based on outdated calculations, while urban development has since increased the impervious surface areas within their catchment zones. As a result, many utility companies have limited insight into rainfall volumes and basin filling rates, potentially leading to basins that are either insufficiently functional or occupying valuable space that could be repurposed.

The most effective way to assess their functionality is through systematic measurement and analysis. Given the busy schedules of utility companies, they often lack the time to manage procurement, installation, and data analysis on their own.

This challenge led to our recent collaboration with a new customer in Jylland, where we are conducting a comprehensive analysis of their stormwater basins. Over the next period we will

Over the next period we will help them understand:

bullet
How quickly do they fill?
bullet
What percentage of their capacity is utilized?
bullet
How often do they overflow? And to what extent are our recipients impacted?

Understanding the relationship the relationship between rainfall recurrence intervals and basin filling levels is crucial. Such analyses can also provide insights into the potential for further urban development or the possibility of repurposing parts of these basins for construction or recreational use.
