Modelling pathogen fate in stormwaters by a particle–pathogen interaction model using population balances
Stormwater is polluted by various contaminants affecting the quality of receiving water bodies. Pathogens are one of these contaminants, which have a critical effect on water use in rivers. Increasing the retention time of water in stormwater basins can lead to reduced loads of pathogens released to the rivers. In this paper a model describing the behaviour of pathogens in stormwater basins is ...

Stormwater retention basin efficiency regarding micropollutant loads and ecotoxicity
Retention basin efficiency in micropollutant removal has not been very well studied, in particular for pollutants highlighted by the European Water Framework Directive of 2000 such as pesticides, polybrominated diphenyl ethers (PBDEs) and alkylphenols. This study is based on in situ experiments carried out on a stormwater retention basin with the aim of estimating the basin efficiency in ...

Vaults - Case Study 3
Description Stormwater catch basin had cracks and crevices allowing infiltration of soil and erosion of the surrounding ground. Originally buried underground, the 30″ incoming pipe had been uncovered from excessive soil erosion. This structure was posing a problem, especially due to its proximity to an airplane runway. Solution The Poly-Triplex Liner System was installed and cured with ...

Role of the biotic compartment in the transfer of zinc through the vadose zone - application to an infiltration system
ABSTRACTRelatively little is known about the influence of microorganisms which develop in urban stormwater infiltration basins on the transfer of heavy metals, whereas many reports have emphasized their importance in the mechanisms of retention or solubilization of these elements. We therefore examined the transfer of zinc solutions (2-20 ppm) at different pH (4-7) by columns of sterile sand or ...

PP18 Module - Service public de l’assainissement francilien (SIAAP) - The Public Sanitation Service, Paris, France - Case Study
THE PROBLEM: The Paris Sanitation Authority (SIAAP), established in 1970, transports and treats wastewater for nine million people in and around Paris. It manages 440 km of pipe, six treatment plants, and 12 stormwater retention basins. With a staff of more than 1,770 employees and an annual budget of 1.3 billion euros, SIAAP covers four areas: Paris, Hauts-de- Seine, Seine-Saint-Denis, and ...

Characterisation and settling of solids in an open, grassed, stormwater sewer network detention basin
ABSTRACTThe objective of the study is to develop new operational management practices for detention tanks during rainfall events in order to limit flooding risk and, at the same time, to reduce pollutant discharges by optimising the settling process. This paper presents the results of the characterisation of settled particles in an open stormwater detention basin with grassed banks and bottom, ...

Influences on the establishment and dominance of vegetation in stormwater infiltration basins
Infiltration basins are widely used in urban environments as a technique for managing and reducing the volume of stormwater. These basins can be spontaneously colonized by wild plants, which can be used as bioindicators of edaphic characteristics. As the basins are anthropogenic environments, the description of plant biodiversity allows the determination of which species colonize such ...

Ecotoxicological characterisation of sediments from stormwater retention basins
Retention–detention basins are important structures for managing stormwater. However, their long-term operation raises the problem of managing the sediments they accumulate. Potential uses for such sediments have been envisaged, but each sediment must be characterised beforehand to verify its harmlessness. In this paper we address this issue through the development of a battery of ...

Protecting Environmental Geomembrane Covers With Suspended GEOWEB Geocells
Economic pressure, the desire for green solutions, and the intensification of climate extremes have converged to create a need for better methods to effect soil stabilization. Fortunately, a proven technology exists that addresses issues associated with these conditions and provides a more stable cover solution for landfill covers, lagoons, stormwater containment basins and other geomembrane ...

Everett, WA - ERH under active storm water retention basin - Case Study
First below water ERH remediation of TCE in active stormwater retention basin Project Summary TRS Group, Inc. (TRS) worked as a sub contractor to Landau Associates on this unique ERH remediation project. This project represents the first of its kind using ERH for site remediation underneath an industrial storm water retention basin full of water. The treatment area is located beneath the north ...

Water sensitive planning and design as an ecologically inspired approach to delivering flood resilient urban environment in Sri Lanka
The paper draws on Colombo, Sri Lanka as the case study for developing Water Sensitive Planning and Design (WSPD) to deliver a flood resilient urban environment. Digital data and documentary data were evaluated to analyse water sensitive characteristics, potentials and constraints within the catchment. Spatial analysis tools in ArcGIS were used when analysing issues in the landscape mosaic. ...

Oil Water Separator Maintenance
Oil water separators (OWS) can be co$tly to maintain, $20,000 or more on average per cleaning and if not properly managed, can be very expensive conduits of pollution. Have you taken steps to minimize the effects and consequences on your operating co$t? When was your facility’s last OWS maintenance performed? Is your employee’s attitude, don’t worry we have an Oil Water ...

Horizontal Plate Clarifiers Treat Power Plant Stormwater - Case Study
Challenge A coal fired power plant needed an upgraded stormwater treatment system to properly deal with high levels of coal ash (from coal pile run-off), solids, and oil prior to discharge. The plant had previously collected run-off and stormwater into in-ground basins that were then pumped through a coalescing (CPI) oil/water separator. The ash and other solids in the stream plugged the ...

Geomembrane protection - Case Study Summary 1
Protecting geomembranes is critical to their long-term performance in many applications including lagoons, detention ponds, storm water containment basins, dikes, temporary dams and landfill covers. The Geoweb® system, with a variety of infills, will provide armor protection to impervious liners or covers so that they can maintain their integrity. Inclusion of internal tendons and ATRA® ...

Usiminis storm water retention basin, Ipatinga, Minas Gerais, Brazil - Case Study
The Problem Usiminas, a Brazilian steel company located in Ipatinga, Minas Gerais, is increasing its production capacity from four million tons annually. The increase in capacity is necessary to keep up with the Brazilian automotive market, which is currently consuming 30% of Usiminas’ production. To increase Usiminas’ production capacity, construction of a new industrial ...

Designing Sustainable Ports & Yards with 3D Geocells
Stabilization for Higher-Performing Pavements Ports and intermodal yards in coastal areas are more prone to pavement problems due to inherent soft, unsupportive soils and high water levels. Heavy traffic patterns and the constant weight of loaded parked trailers and stacked containers at these facilities can accelerate the degradation of the paved or unpaved surfaces and subbase materials. The ...

Construction Site Stormwater Management - Case study
Issues and Challenges: Turbid construction stormwater. No on-site collection basins or management options. Diminished site access. Staging area restricted. Methods and Solutions: Low cost approach involved the placement of poly lined high-sided dumpsters for water storage and settling. A series of Biostar-CH Floc 500 bags were placed in line to treat water as it was pumped. The treated ...

Dry cleaning plant: Boston, Massachusetts
Site Summary Dry cleaning solvents were found in the soil under a parking lot adjacent to a large dry cleaning plant located in a mixed commercial and residential suburb of Boston, Massachusetts. The contamination was traced back to a storm water catch basin in the parking lot which contained sediment and sludge with high concentrations of the dry cleaning solvent perchloroethene (PCE). The ...

Water management solutions minimize flood damage
Human societies around the world have used timber as a building material for thousands of years. As wood is the only significant biological building material we are naturally inclined to believe that using wood in construction is good for the environment. As a matter of fact the environmental benefits of using timber are not straightforward: although it is a natural product, a large amount of ...
