Evaluating the success of sewer reconstruction by using carbamazepine as anthropogenic marker in groundwater

The antiepileptic drug carbamazepine is a useful anthropogenic marker in groundwater to detect and quantify sewer exfiltration. In 2003 its application on a city wide scale enabled the identification of a trunk sewer in extremely bad structural status with an exfiltration (of wastewater into groundwater) rate in the adjacent area of around 5% compared to an average of approximately 1% in other ...

Taking Action for The Future

Sewer networksoperate with practically no installed monitoring of any kind. This simple picture is beginning to change for two main reasons. Firstly, consumers expect ever higher standards from service providers of all kinds, and sewerage undertakers are beging challenged by this. Secondly, environmental legislation is demanding much higher performance from wastewater collection and treatment ...

Municipal sewer remote monitoring

Sewers are critical heavy duty infrastructure components requiring costly maintenance. Many municipalities suffer from ageing pipelines that pose higher chances of failure. Sewer leak or overflow results in high cost as a result of civil reimbursement and due to inflected illness. Moreover Civilian frustration that results form the overflow is often targeted towards the municipality. Overflow can ...

Sewer Sociology – The Days of Our (Sewer) Lives

ABSTRACTFor centuries mankind has recorded life’s events through hieroglyphics, stories, and books. In similar fashion, those of us in the sewer business recognize the daily rhythm of people’s lives through the diurnal patterns of water and sewer use. Differences can be seen between weekdays, weekends, and holidays, and other distractions and disruptions of everyday life can often be seen as a ...

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 ...

Evaluation of effectiveness of combined sewer overflow control measures by operational data

The effect of combined sewer overflow (CSO) control measures should be validated during operation based on monitoring of CSO activity and subsequent comparison with (legal) requirements. However, most CSO monitoring programs have been started only recently and therefore no long-term data is available for reliable efficiency control. A method is proposed that focuses on rainfall data for ...

Performance assessment of separate and combined sewer systems in metropolitan areas in southern China

To assess the performance of urban drainage systems in metropolitan areas in southern China, 12 urban drainage systems, including nine separate sewer systems (SSSs) and three combined sewer systems (CSSs) were monitored from 2008 to 2012 in Shanghai and Hefei. Illicit connection rates of SSS were determined. The results indicate that serious illicit connections exist for most SSSs. Annual ...

Flow measurements in sewers based on image analysis: automatic flow velocity algorithm

Discharges of combined sewer overflows (CSOs) and stormwater are recognized as an important source of environmental contamination. However, the harsh sewer environment and particular hydraulic conditions during rain events reduce the reliability of traditional flow measurement probes. An in situ system for sewer water flow monitoring based on video images was evaluated. Algorithms to determine ...
