“…Although integrated urban water system (IUWS) modeling is usually used as a tool for evaluating the quality of the surface water receiving the municipal WWTP discharge combining sewer overflows and stormwater drainage systems, many micropollutants tend to distribute to more than one environmental compartment (air, water, sediment, soil, groundwater, etc.). Hence, a multimedia fate and transport model (MFTM) was proposed by De Keyser et al (2010) to meaningfully characterize the attenuation and distribution of micropollutants.…”

Micropollutants are emerging as a new challenge to the scientific community. This review provides a summary of the recent occurrence of micropollutants in the aquatic environment including sewage, surface water, groundwater and drinking water. The discharge of treated effluent from WWTPs is a major pathway for the introduction of micropollutants to surface water. WWTPs act as primary barriers against the spread of micropollutants. WWTP removal efficiency of the selected micropollutants in 14 countries/regions depicts compound-specific variation in removal, ranging from 12.5 to 100%. Advanced treatment processes, such as activated carbon adsorption, advanced oxidation processes, nanofiltration, reverse osmosis, and membrane bioreactors can achieve higher and more consistent micropollutant removal. However, regardless of what technology is employed, the removal of micropollutants depends on physico-chemical properties of micropollutants and treatment conditions. The evaluation of micropollutant removal from municipal wastewater should cover a series of aspects from sources to end uses. After the release of micropollutants, a better understanding and modeling of their fate in surface water is essential for effectively predicting their impacts on the receiving environment.

“…In WEST®, a multimedia fate and transport model (MFTM) is "wrapped around" a dynamic IUWS model for organic micropollutants to enable integrated environmental assessment ( Figure 2) (De Keyser et al, 2009b). The MFTM implemented in WEST® is based on the 'regional' scale of the SimpleBox model (den Hollander et al, 2003).…”

The modelling of urban water quality (i.e. wastewater, stormwater) is a growing issue in water management. New regulations stress the importance of estimating the loads and the fate of micro-pollutants (MPs) in the urban water cycle. The models available to simulate the transport and removal of "traditional" pollutants such as overall organic pollution, nutrients and suspended solids in the different components of the urban water system (i.e. sewer network, stormwater treatment units, wastewater treatment plant, receiving waters) were extended with processes affecting the fate of MPs (i.e. physical, chemical and biological) depending on the compound's inherent properties. This paper describes the modelling approach and some possible applications of these unit process models including their combination to simulate urban water systems by means of three examples, developed within the EU project SCOREPP.

“…Large urban areas have been “waterproofed” by human activities [2], increasing the risk of higher runoff volumes [3], with increased flooding and larger pollutant loads entering water bodies [4]. Runoff in urban areas is transported in the storm sewer system, and with predictions of climate change increasing rainfall intensities and extreme events, drainage systems and treatment plants are at high risk of becoming outdated [5]. Combined sewer overflows (CSOs) are a well-known consequence of such increased surface water flows, leading to the spread of pollution over urbanised areas [6].…”

Intense urbanisation, combined with climate change impacts such as increased rainfall intensity, is overloading conventional drainage systems, increasing the number of combined sewer overflow events and making treatment plants outdated. There is a need for better urban planning, incorporating stormwater and flood management design in order to accurately design urban drainage networks. Geographic Information System (GIS) tools are capable of identifying and delineating the runoff flow direction, as well as accurately defining small-sized urban catchments using geospatial data. This study explores the synergies between GIS and stormwater management design tools for better land-use planning, providing a new methodology which has the potential to incorporate hydraulic and hydrological calculations into the design of urban areas. From data collection to final results, only freely available software and open platforms have been used: the U.S. EPA Storm Water Management Model (SWMM), QGis, PostgreSQL, PostGIS, SagaGIS, and GrassGIS. Each of these tools alone cannot provide all the necessary functionalities for large-scale projects, but once linked to GISWATER, a unique, fast, efficient, and accurate work methodology results. A case study of a newly urbanised area in the city of Gijón (northern Spain) has been utilised to apply this new methodology.
