CSOnet is a sensor actuator network that monitors and controls the frequency of combined sewer overflow (CSO) events in city sewer systems. CSO events constitute a major health and environmental hazard which numerous U.S. cities have been attempting to address. This paper describes an ongoing project building a metropolitan scale CSOnet in the City of South Bend Indiana.

Coastal wastewater and storm water systems can be overwhelmed during high precipitation events, particularly when compounded by surge that blocks spillways drainage ways. Sea level rise (SLR) brings increased risk of such compound flooding triggering sanitary sewer overflows (SSO) which release waste into the local environment. A logistic regression model was developed to better predict this in...

Abstract Direct measurement of the flow rate in sanitary sewer lines is not always feasible and an important parameter for normalization data used wastewater-based epidemiology applications. Machine learning to estimate past wastewater influent rates supporting public health applications has been studied. The aim this study was assess treatment plant when compared with weather retrospectively L...

As one of major underground pipelines, sewerage is an important infrastructure in any modern city. The most common problem occurring in sewerage is leaking, whose position and failure level is typically identified through closed circuit television (CCTV) inspection in order to facilitate rehabilitation process. This paper proposes a novel method of computer vision, morphological segmentation ba...

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Impact of dry weather discharges on annual pollution from a separate storm sewer in Toulouse, France. • Dry weather discharges from storm sewers have an impact on annual pollution load. • The more urbanized the outlet is, the more important the pollution i...

Rather than seeing landscape as an invisible backdrop to sanitary reform, this article offers another context through which to consider the problems facing local authorities and sanitary officials in identifying and tackling sanitary problems. Using Wales as a case study, this article first addresses how rural landscapes were imagined and second how as "environments" and "territories" they infl...

INTRODUCTION The aim of this study was to determine the problems encountered during investigations into causes of death in corpses found in wells, sewer systems and pits, and to seek solutions to the problems. In fact, wells, sewer systems and pits have some common characteristics which may cause the problems. They contain water, have a hypoxic/anoxic environment and prevent corpses from being ...
