Evaluating
Escherichia coli removal performance in stormwater biofilters: a preliminary modelling approachStormwater biofilters are not currently optimised for pathogen removal since the behaviour of these pollutants within the stormwater biofilters is poorly understood. Modelling is a common way of optimising these systems, which also provides a better understanding of the major processes that govern the pathogen removal. This paper provides an overview of a laboratory-scale study that ...

Simulating organic pollutant flows in urban stormwater: development and evaluation of a model for nonylphenols and phthalates
Stormwater-quality models can be useful tools for predicting pollutant loads and identifying sources of contamination. Most models in current use handle pollutants such as metals, nutrients and suspended solids, whereas models including emerging organic contaminants are rare. This study aims at developing and evaluating a model for simulating stormwater flows of two groups of organic pollutants; ...

Characterization and source identification of stormwater runoff in tropical urban catchments
The characteristics of urban stormwater pollution in the tropics are still poorly understood. This issue is crucial to the tropical environment because its rainfall and runoff generation processes are so different from temperate regions. In this regard, a stormwater monitoring program was carried out at three urban catchments (e.g. residential, commercial and industrial) in the southern part of ...

Stormwater Management Program Long-Term Effectiveness Monitoring: Can I Reduce Sampling Frequency and Still Detect Trends to Determine BMP Effectiveness
INTRODUCTION Stormwater program managers are challenged with meeting regulatory monitoring requirements to identify long-term trends and the effectiveness of the implementation of Best Management Practices (BMPs) and meeting multiple program requirements with finite resources. This paper provides stormwater managers with methods and several real-world scenarios using 10 years of data from the ...

A systematic approach to determine herbicide removals in constructed wetlands using time integrated passive samplers
Natural water treatment systems such as wetlands are increasingly being recognised for their role as part of a multi-barrier system for water recycling. Natural wetland systems have the ability to provide effective treatment for a wide range of organic chemicals. However, techniques are required to validate the performance of these treatment processes in the field. This paper provides a new ...

Reference pathogen numbers in urban stormwater for drinking water risk assessment
Targeted stormwater event-based monitoring of adenovirus, Cryptosporidium and Campylobacter, the human health reference pathogens of viruses, protozoa and bacteria, respectively, was undertaken to determine numbers prior to water recycling via an aquifer. This allowed the determination of a 95th percentile of reference pathogen numbers in stormwater (2 n/L for adenoviruses, 1.4 n/L for ...

Pilot plant study for one year: water quality management and algal control of sustainable urban stormwater ponds
Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and public acceptance. The purpose of ...

Comparative evaluation of runoff and water quality using HSPF and SWMM
Stormwater pollution is the untreated contaminated water that drains into natural waterways from land uses within an urban catchment. Several studies have demonstrated the deterioration of water quality in receiving bodies of water caused by stormwater runoff. The data have reported that urban runoff play primary roles in degrading water quality in adjacent aquatic systems. The accurate ...

Searching for storm water inflows in foul sewers using fibre-optic distributed temperature sensing
A major drawback of separate sewer systems is the occurrence of illicit connections: unintended sewer cross-connections that connect foul water outlets from residential or industrial premises to the storm water system and/or storm water outlets to the foul sewer system. The amount of unwanted storm water in foul sewer systems can be significant, resulting in a number of detrimental effects on ...

From mess to mass: a methodology for calculating storm event pollutant loads with their uncertainties, from continuous raw data time series
With the increasing implementation of continuous monitoring of both discharge and water quality in sewer systems, large data bases are now available. In order to manage large amounts of data and calculate various variables and indicators of interest it is necessary to apply automated methods for data processing. This paper deals with the processing of short time step turbidity time series to ...

Sensitivity analysis of an urban stormwater microorganism model
This paper presents the sensitivity analysis of a newly developed model which predicts microorganism concentrations in urban stormwater (MOPUS—MicroOrganism Prediction in Urban Stormwater). The analysis used Escherichia coli data collected from four urban catchments in Melbourne, Australia. The MICA program (Model Independent Markov Chain Monte Carlo Analysis), used to conduct this analysis, ...

OSU researchers deploy Stevens equipment in study of green infrastructure treatment for groundwater runoff - Case Study
Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30 years, the infrastructure for ...
