Impervious Area

Because of multiple constraints, e.g. existing drainage systems, little available space and higher costs, Best Management Practices (BMP) for stormwater-runoff in existing urban areas is more difficult to apply than for new urban developments. For a large urban catchment (about 22 km2) with a separate drainage system in Berlin, Germany a combination of decentral (non-structural) and semi-central stormwater-management measures proved to be the best solution. It offers a high effectiveness concerning stormwater treatment at relatively low costs. Modern planning tools such as Geographic Information Systems (GIS) were used to investigate the possibilities of implementing decentral measures in larger areas. Correlations between field surveys and data from the ‘Environmental Information System’ of Berlin shows that even in highly urbanised areas a disconnection of 30% of the impervious area can easily be achieved. The resulting reduction of the discharge makes it possible to convert existing retention tanks to soil filter tanks. The purification efficiency of this combined measures is higher than of a central stormwater settling tank which has been simulated with a pollution load model.

The Usa

Bacteria are one of the major causes of surface water impairments in the USA. Over the past several years, best management practices, including detention basins, manufactured devices, grass swales, filters and bioretention cells have been used to remove bacteria and other pollutants from stormwater runoff. However, there are data gaps in the comprehensive studies of bacteria concentrations in stormwater runoff. In this paper, the event mean concentration (EMC) of fecal indicator bacteria (Enterococcus, Escherichia coli, fecal Streptococcus group bacteria, and fecal coliform) across the USA was retrieved from the international stormwater best management practices database to analyze the seasonal variations of inflow and outflow event mean concentrations and removal efficiencies. The Kruskal–Wallis test was employed to determine the seasonal variations of bacteria indicator concentrations and removals, and the two-sample Kolmogorov–Smirnov test was used for comparing different seasonal outcomes. The results indicate that all the inflow EMC of FIB in stormwater runoff is above the water quality criteria. The seasonal differences of fecal Streptococcus group bacteria and fecal coliform are significant. Summer has the potential to increase the bacteria EMC and illustrate the seasonal differences.

Conflicting Objectives

Low-impact development (LID), a land planning and engineering design approach for managing urban stormwater runoff, has been widely adopted across the globe. LID best management practices (BMPs) are man-made features that rely on natural processes to manage stormwater water quantity and quality. In this article, recent literature (published after the year 2008) related to nine BMPs was reviewed to highlight the ranges in treatment efficiencies for 21 of the most frequently investigated runoff parameters. The primary function, pros and cons, and factors affecting performance of each BMP were discussed. A frequency analysis of the reviewed parameters showed that total suspended solids, total phosphorous, total nitrogen, runoff reduction, and zinc concentrations were the most frequently investigated stormwater runoff parameters. Five recurring themes were observed with regards to knowledge gaps and conflicting objectives for research related to LID BMPs that include: (i) lack of consensus on which parameters to measure for effective LID adoption, (ii) BMP performance is highly variable, (iii) many BMPs are known exporters of nutrient pollutants, (iv) lack of cold weather performance-specific studies for individual BMPs, and (v) lack of human pathogen-related stormwater quality studies for individual BMPs. Suggestions for future research are discussed to address these knowledge gaps.

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.
