Stormwater is the major water inflow to many water bodies in Stockholm. Stockholm City has adopted a strategy, which defines the need to treat different kinds of stormwater entering different receiving waters. The Stockholm Water Company has tested various ways of treating stormwater. In 2000, the City of Stockholm arranged a stormwater treatment technology competition. Prizes were awarded to four winning entries. One installation was completed in 2001 and another is now under construction.

Drying Regime

Biofiltration systems are an effective stormwater treatment technology. However, their robustness is yet to be tested, particularly their performance following extended dry periods. The hydraulic and treatment performance of five different non-vegetated, soil-based filters under varying periods of inundation and drying was assessed. The infiltration capacity of the filters decreased during wet periods and increased following dry periods, most probably due to swelling and shrinkage of the filter media. Treatment of sediment, heavy metals and phosphorus was not influenced by the wetting and drying regime. However, outflow concentrations of nitrogen were significantly higher upon re-wetting following extended dry periods compared with wet periods. This result has implications for current design practices, as these nitrogen pulses could negatively impact the ecological health of downstream receiving waters.

Receiving Water

Urbanization results in great changes to the landscape and the water environment simply because stormwater runoff differs in quantity and quality from the pre-urbanization state. Streams, rivers, lakes, estuaries and other receiving water bodies experience the changes to runoff frequencies and volumes and react accordingly. The forces behind the observed changes in the receiving waters are discussed in this paper and suggestions are made on how to plan to deal with them. Urban watershed and waterway master planning can help to mitigate, in large part, the impacts imposed on these waters by land-use changes. Although each watershed is unique, some general principles are suggested to deal with these emergent problems.

Nowadays, it is a common ascertainment that stormwater runoff in the urban and interurban road network consist non-point source pollution which contributes to the degrading of the quality of water of ground and surface water bodies. Taking into account the fact that water pollution has impacts to people and also to flora and fauna, the need to take measures in order to confront this environmental problem becomes inevitable. The adverse impacts of the stormwater runoff can be minimized with structural and non-structural Best Management Practices (BMPs) or with a combination of them. Within the content of the present paper the following are included: a) the investigation and presentation of the receiving waters pollution issues from the highway road network stormwater runoff together with the European transport policy concerning the development of an integrated highway road network, b) the examination of the respective pollutant generation and characteristics, c) the presentation of their impacts, d) the examination of the measures (structural and nonstructural BMPs), e) the presentation of the “first flush” phenomenon, f) The presentation of the existing legislation in the EU with emphasis in the E.U. Directive 2000/60/EC as well as the presentation of the relevant existing environmental legislation in Greece, including also the presentation of the way the Highway Guidelines actually deal with the specific problem.

The small town of Waldenburg in South Germany planned to continue the implementation of stormwater treatment. The CSO-Masterplan dated from the year 1976. Meanwhile, new guidelines were issued and new technologies became available, like mathematical sewer models. Since the ecological impact of stormwater treatment is today much more accounted for, it was decided to revise the CSO-Masterplan. The goal was to find a solution with minimized ecological impact at low costs. This urban hydrological study featured some unusual approaches. First, the present state of city, sewer system, treatment plant and receiving waters was analyzed in an interdisciplinary field study. Using the quantity-quality sewer model ASMI, the annual pollutant loads for various planning alternatives were calculated. This allowed statements about the environmental impact of each alternative, taking into account the sensitivity of the receiving waters known from the biological field study. The proposed final alternative saved nearly 1 million DM at a much lower impact on the environment compared with the original planning, showing that it is possible to cope equally with ecological and economical requirements.

Clean water is a vital need for all living creatures during their lifespan. However, contaminated stormwater is a major issue around the globe. A wide range of contaminants, including heavy metals, organic and inorganic impurities, has been discovered in stormwater. Some commonly utilized methods, such as biological, physical and chemical procedures, have been considered to overcome these issues. However, these current approaches result in moderate to low contaminant removal efficiencies for certain classes of contaminants. Of late, filtration and adsorption processes have become more featured in permeable concretes (PCs) for the treatment of stormwater. As nanoparticles have vast potential and unique characterizations, such as a higher surface area to cure polluted stormwater, employing them to improve permeable concretes’ capabilities in stormwater treatment systems is an effective way to increase filtration and adsorption mechanisms. The present study reviews the removal rate of different stormwater contaminants such as heavy metals, organic and other pollutants using nanoparticle-improved PC. The application of different kinds of nanomaterials in PC as porous media to investigate their influences on the properties of PC, including the permeability rate, compressive strength, adsorption capacity and mix design of such concrete, was also studied. The findings of this review show that different types of nanomaterials improve the removal efficiency, compressive strength and adsorption capacity and decrease the infiltration rate of PC during the stormwater treatment process. With regard to the lack of comprehensive investigation concerning the use of nanomaterials in PC to treat polluted stormwater runoff, this study reviews 242 published articles on the removal rate of different stormwater contaminants by using PC improved with nanoparticles.

Several cities in developing countries are challenging the permanent process of urbanization. This generates a great disturbance on the hydrological response of the urbanized area during rainfall events, which can cause floods. Among the disturbances that urbanized basins may suffer, it is found that variations in rain losses (hydrological abstractions) can be estimated by the named volumetric runoff coefficient (CVOL) methodology. In the present study, this methodology is used in an attempt to estimate the hydrological abstraction of two nearby urbanized basins, with different degrees of impermeability, located in the city of Cuenca in Ecuador. The data for that analysis were collected between April and May of 2017. The results obtained indicate that the micro-basin with the largest impervious area presents the higher initial hydrological losses, the higher rate of decrease in abstractions, and the higher stormwater runoff flows per unit area. In addition, the abstractions found in the two urban micro-basins show great sensitivity to the maximum rainfall intensity and do not relate to the antecedent soil moisture. These results demonstrate the importance of having higher pervious surfaces in urbanized areas because they lead to reduce negative impacts associated with increased stormwater runoff on impervious surfaces.

Construction activities have been identified as one of the major sources of pollution to receiving waters. Although Erosion and Sediment Control (ESC) measures reduce the amount of sediment exported from construction sites, there are still significant concerns regarding the sufficiency of current control measures to protect receiving waters. This study documents the work completed to monitor and model the performance of a typical stormwater management facility used for erosion and sediment control in suburban construction site. The main objective of this study is to provide background information regarding the performance of stormwater management facilities for treating urban construction runoff prior to discharging to receiving water bodies. The RUNOFF and STORAGE TREATMENT blocks of EPA's stormwater management model (PCSWMM4.4) were used to simulate the quantity and quality of stormwater run-off from the area under construction and assess the performance of stormwater treatment facility (Ballymore Pond) located in Richmond Hill, Ontario. The performance of the construction site sediment control pond was found to be unsatisfactory due to the high outflow concentration of suspended solids. Some specific recommendations to improve its effectiveness have been made.

Incident Analysis

A forensic engineering analyses of a chemical incident is presented that was classified as a self-sustaining decomposition (SSD) event, which occurred in a load of 10,000 tons of NK 21-00-21 fertilizer bulk stored inside a warehouse in the city of São Francisco do Sul in Brazil. The chemical reaction developed within the fertilizer mass and took several days to be controlled, resulting in the evacuation of thousands of residents. The water used to fight against the reaction, after having contact with the load of fertilizer material, promoted changes in adjacent water bodies, causing the death of animals (fish, crustaceans, and amphibians). The smoke from the chemical reaction products damaged the incident’s surrounding vegetation. Large SSD events are rare, with an average worldwide frequency of one every three years. Therefore, in addition to presenting a case study of this type of phenomenon, the main objective of this work is to discuss the causes that led to SSD reaction at this event, evaluate its consequences, and motivate future studies.
