“…Thus, TSS may be considered a source of concern for longterm human and ecological well-being. The risks related to suspended solids bound fraction of metals/metalloids are primarily related to the potential for phase shift into more bioavailable forms, resulting in chronic toxicity [12,21,22,23,24].…”

Extreme weather events caused by climate change are becoming more frequent all across the world, particularly in the Northern Hemisphere, where these events manifest themselves as more severe or long-lasting rainfalls. Because the typical response, infrastructure refurbishment, is costly and time consuming, it is necessary to develop and implement alternative, more resource efficient, stormwater management methods. The methods must benefit both the urbanites as well as the natural environment, but they must be grounded on a comparative examination of alternatives. The purpose of this paper is to evaluate the trade-offs between several stormwater control strategies in the context of climate change, such as no intervention, water quality-based intervention, water quantity-based intervention, and a combined approach. Each of the aforementioned approaches is considered to have intrinsic advantages and disadvantages that should be examined and quantified. Analysis of these trade-offs is critical because it provides some insight into the feasibility of implementing various stormwater management strategies for protecting the environment. The SWMM software was used to analyse the various scenarios, and the model was built using data from multiple national databases as well as data sets provided by the Municipality of Viimsi in Estonia. This study confirmed that water quality protection can be prioritized even in densely populated areas without jeopardizing citizens’ well-being or causing unnecessary floods. This can be accomplished even with simple rule-based control if the necessary hardware, such as sensors and flow devices for digitalizing and combining inter-linking stormwater infrastructure are installed on-site. Through the SWMM simulations it was determined that digitalization of the stormwater solutions allows for a 30-92% reduction in flow, and consequently a 50-90% reduction in pollution load entering the Baltic Sea.

“…This has given rise to the use of Real Time Control (RTC), whereby the urban drainage system (UDS) is dynamically controlled based on real-time information of the system state (Schütze et al 2002). The control objective varies based on the UDS characteristic and preferences of the operator and can take the form of CSO volume reduction (Schilling et al 1996), pollution load reduction (Ly et al 2019;Sun et al 2020), environmental impact minimization (Langeveld et al 2013; or energy use optimisation (Kroll et al 2018). Multi-objective control, where several objectives are formalised together, have also been reported (Ocampo-Martinez et al 2008).…”

To evaluate the performance of Real Time Control (RTC) of urban drainage systems (UDS) a comparison is made with the pre-RTC situation, making the RTC performance dependent on the functioning of the UDS prior to implementation. To standardise things, a generalised baseline is formulated here as the operation with optimal static settings of the UDS. Two maximum theoretical potential performances are then calculated, one including and one excluding system limitations. These are combined with the generalised baseline to form Realised Potential Indicators (RPIs), objective values which indicate the proximity of the RTC strategy to its maximum potential. The proposed methodology was demonstrated on the case study of Eindhoven, the Netherlands. The results obtained show that using RPIs allows for a more objective assessment and improved understanding of the efficacy of different RTC procedures. Additionally, the RPIs can provide an indication if RTC is sufficient to achieve the desired UDS performance.
