Integrated urban water management in commercial buildings

Monitoring results are presented as an annual water balance from the pioneering Landcare Research green building containing commercial laboratory and office space. The building makes use of harvested roof runoff to flush toilets and urinals and irrigate glasshouse experiments, reducing the demand for city-supplied water and stormwater runoff. Stormwater treatment devices also manage the runoff ...

Assessment of LID practices for restoring pre-development runoff regime in an urbanized catchment in southern Finland

This study quantifies the effects of common stormwater management techniques on urban runoff generation. Simulated flow rates for different low impact development (LID) scenarios were compared with observed flow rates during different urban construction phases in a catchment (12.3 ha) that was developed from natural forest to a residential area over a monitoring period of 5 years. The Storm ...

Experimental analysis of green roof substrate detention characteristics

Green roofs may make an important contribution to urban stormwater management. Rainfall-runoff models are required to evaluate green roof responses to specific rainfall inputs. The roof's hydrological response is a function of its configuration, with the substrate – or growing media – providing both retention and detention of rainfall. The objective of the research ...

Manage Stormwater Runoff with Skimming Technology

When the sky cries, that’s a natural phenomenon. But when Nature’s pure water mixes with various types of oil and hydraulic fluids or other contaminants, the result is a man-made problem. Commonly called stormwater runoff, rainwater will flow wherever it wants once it hits Earth. And this characteristic is what makes water troublesome wherever it encounters oil – in heavy ...

Understanding the factors influencing the removal of heavy metals in urban stormwater runoff

In this research, an infiltration trench equipped with an extensive pretreatment and filter bed consisting of woodchip, sand and gravel was utilized as a low impact development technique to manage stormwater runoff from a highly impervious road with particular emphasis on heavy metal removal. Findings revealed that the major factors influencing the removal of heavy metals were the ...

Integration of Watershed Planning and Wellhead Protection Programs

For communities using groundwater as the primary source of water supply, delineating, managing, and protecting the wellhead recharge area is essential to assuring a sustainable water resource system. Because many communities are also required to obtain a National Pollutant Discharge Elimination System (NPDES) permit for discharges from municipal separate storm sewer systems (MS4s), delineating ...

Protocols for Evaluating the Effects of Land-use Patterns and Runoff Management on Urban Streams

ABSTRACTThe design of urban runoff management facilities generally includes peak shaving for flood control, and best management practices (BMPs) for removing pollutants from the runoff. A number of scientists have concluded that the combination of these two control practices, which were developed independently of one another, is not sufficient to protect aquatic ecosystems. But these conclusions ...

Contributions to the design of rainwater harvesting systems in buildings with green roofs in a Mediterranean climate

Green roofs (GRs) are becoming a trend in urban areas, favouring thermal performance of buildings, promoting removal of atmospheric pollutants, and acting as possible water collection spots. Rainwater harvesting systems in buildings can also contribute to the management of stormwater runoff reducing flood peaks. These technologies should be enhanced in Mediterranean countries where water ...

The importance of wastewater treatment in shipbuilding industry

There is a huge amount of wastewater outcome during the ship production and repair processes in shipyards. Especially production processes (blasting, welding, painting, machining and metalworking), repair processes (hull washing) and painting processes (paint removal) create a huge amount of wastewater. In addition to these, open area processes of ship repair and maintenance cause stormwater ...

Physical design optimization of an urban runoff treatment system using Stormwater Management Model (SWMM)

The study presented the application of Stormwater Management Model (SWMM) in determining the optimal physical design properties of an established low impact development (LID) system treating road runoff. The calibration of the model was based on monitored storm events occurring from May 2010 to July 2013. It was found that the total suspended solids was highly correlated with stormwater ...

Runoff projections grasspave2 & gravelpave2/effective imperviousness

Performing stormwater drainage design is one of the requirements of a site designer. Recent regulations created and enforced by the EPA require new developments to limit the amount of stormwater that flows off of a newly developed site, to be equivalent to or less, than the flow rate prior to development. The site designer must determine how much water is running off the original site, and ...

GIS-Based Rapid Geomorphic Assessment to Guide Sustainable River Restoration and Riverfront Redevelopment: Four Mile Run, Alexandria, Virginia

ABSTRACT A Geographic Information System (GIS)-based geomorphic assessment was performed to quickly identify opportunities and constraints for a river restoration and riverfront redevelopment project along Four Mile Run in Alexandria, Virginia. This assessment was further used to guide channel restoration design. Components of the GIS-based geomorphic assessment included the following: 1) ...

City of Santa Monica Airport Watershed Management Plan

ABSTRACT The City of Santa Monica implements best management practices (BMPs) to address urban stormwater runoff and uses a “hierarchy” of BMPs to prioritize implementation based on the principles of protecting public safety and the environment, maximizing environmental benefits, and minimizing costs. The hierarchy of BMPs includes the following (in order of priority): 1) harvesting, treating, ...

Integration of urban runoff and storm sewer models using the OpenMI framework

This paper presents an integrated modeling approach that combines the legacy urban runoff and the legacy storm sewer models with data exchange at runtime to simulate sewer flows with real-time rainfalls. A software system called IRES has been developed to demonstrate the proposed approach. IRES uses the RUNOFF and the EXTRAN block of Storm Water Management Model (SWMM) as the legacy urban ...

Micro-zooplankton grazing as a means of fecal bacteria removal in stormwater BMPs

A priority for environmental managers is control of stormwater runoff pollution, especially fecal microbial pollution. This research was designed to determine if fecal bacterial grazing by micro-zooplankton is a significant control on fecal bacteria in aquatic best management practices (BMPs); if grazing differs between a wet detention pond and a constructed wetland; and if environmental ...

Modelling and optimization of land use/land cover change in a developing urban catchment

The impacts of land use/cover change (LUCC) on hydrological processes and water resources are mainly reflected in changes in runoff and pollutant variations. Low impact development (LID) technology is utilized as an effective strategy to control urban stormwater runoff and pollution in the urban catchment. In this study, the impact of LUCC on runoff and pollutants in an urbanizing catchment ...

Dynamic stormwater treatment unit model for micropollutants (STUMP) based on substance inherent properties

Modelling the removal of micropollutants (MPs) in stormwater treatment systems is essential in a context that is characterized by a general lack of measurements. This paper presents an innovative dynamic model for the prediction of the removal of MPs in stormwater treatment systems (Stormwater Treatment Unit model for Micro Pollutants—STUMP). The model, based on a conceptual model of ...

Evaluation of the relative roles of a vegetative filter strip and a biofiltration swale in a treatment train for road runoff

In order to determine the relative importance of a vegetative filter strip and a biofiltration swale in a treatment train for road runoff, US EPA Storm Water Management Model was used to model infiltration and runoff from the filter strip. The model consisted of a series of subcatchments representing the road, the filter strip and the side-slopes of the swale. Simulations were carried out for ...
