Overview of the (Smart) Stormwater Management around the Baltic Sea

Abstract

In this review paper, we investigate the management of the quality of stormwater in the Baltic Sea region. Current stormwater management practices, standards, and legislation do not accurately depict stormwater quality, resulting in an underestimation of its environmental impact. The digitalization and harmonization of stormwater management through the implementation of e-monitoring (online or continuous monitoring) allow for the collection of data. This data can be used to improve stormwater quality and quantity management, thereby reducing the environmental harm induced by anthropogenic activities. Based on the literature review, supporting tables and matrices are proposed to assist decision-makers and other interested parties in developing and implementing “smart” stormwater management solutions. In this article, we demonstrate that such systems can enhance stormwater management and system performance by leveraging data-driven operation and maintenance. Another advantage of the approach is that it contributes to a healthier urban environment and ecosystem well-being.
