The civil infrastructure including highways, bridges, and water/sewer systems, is crucial for economic growth and prosperity. Among the various infrastructure systems, sewer pipelines networks represent a great challenge due to their diverse components that have different repair requirements. This paper introduces a comprehensive asset management framework to support the efficient planning of m...

When looking at acute receiving water impacts due to combined sewer overflows the characteristics of the background diurnal sewage flux variation may influence the peak loads from combined sewer overflows (CSO) and wastewater treatment plant (WWTP) effluent significantly. In this paper, effects on the dynamic compounds transported in the sewer, on CSO discharges and WWTP loading are evaluated b...

Real-time monitoring of water quality for sewer system is required for efficient sewer network design because it provides information on the precise loading of pollutant to wastewater treatment facilities and the impact of loading on receiving water. In this study, synchronous fluorescence spectra and its first derivatives were investigated using a number of wastewater samples collected in sewe...

We investigated the effectiveness of Escherichia coli community fingerprinting for identifying fecal pollution sources impacting a recreational beach. E. coli in water collected from the beach, nearby creek and storm sewer outfall were enumerated using membrane filtration, while E. coli communities were characterized following polymerase chain reaction analysis and denaturing gradient gel elect...

All the parts of an urban drainage system, i.e. the sewer system, the waste water treatment plant (WWTP) and the river, should be integrated into one single model to assess the performance of the overall system and for the development of design and control strategies assisting in its sustainable and cost effective management. Existing models for the individual components of the system have to b...

A large number of human diseases are related to poor access to water and sewer systems, inadequate solid waste management and deficient storm water drainage. The goal of this study was to formulate environmental sanitation indicators and classify sanitation conditions in specific sewer basins and their respective neighborhoods. The database used contains information on the following sanitation ...

Sewer flooding incidents in the UK are being increasingly associated with the presence of blockages. Blockages are difficult to deal with as although there are locations where they are more likely to occur, they do occur intermittently. In order to manage sewer blockage pro-actively sewer managers need to be able to identify the location of blockages promptly. Traditional closed-circuit televis...

The paper addresses the navigation problem for an autonomous robot designed to inspect sewerage. The robot, which is about half size of the sewer diameter, must keep its orientation in the entirely dark sewerage. The only a priory information known is the geometrical shape of the sewer (cylindrical, etc). This implies a strong geometrical constraint on the environment the robot can expect. In t...
