Bayesian experimental design of tracer studies to monitor wastewater leakage from sewer networks

Despite more than a decade of research, the magnitude of wastewater leakage from defective sewer systems into groundwater supplies is still largely unknown, partly because reliable measurement

Harmonized assessment of nutrient pollution from urban systems including losses from sewer exfiltration: a case study in Germany

This study proposes an extended model framework which incorporates sewer exfiltration pathway in the catchment model for a better justified pollution control and management of urban systems at a nationwide scale and provides a first harmonized quantification of potential leakage losses in urban wastewater systems at the nationwide scale.

Exploring global nitrogen and phosphorus flows in urban wastes during the twentieth century

This paper presents a global model‐based country‐scale quantification of urban N and P mass flows from humans, animals, and industries and their waste N and P discharges to surface water and urban

Modelling of groundwater infiltration into sewer systems

Groundwater infiltration into urban sewers represents a problem that influences costs and management of technical systems. The hydrodynamic groundwater software MODFLOW is used to analyse the

Hydraulic modelling of sewage exfiltration.

Investigations are introduced, which are focused on the actual water content of the soil and its influence on exfiltration rates, and it was found, that the matrix potential increases the tightness of the colmation layer.

Zasnova baze podatkov in predlog metodologije za določitev prioritete obnove kanalizacijskega omrežja : magistrsko delo

The model for determining optimal rehabilitation of wastewater system was developed and test and multi-criteria decision-making was used for choosing the optimal rehabilitation method according to five criteria.

THE COLMATION OF LEAKS IN SEWER SYSTEMS DURING DRY WEATHER FLOW

This paper examines the performance of infiltration of wastewater into the groundwater due to leaks in sewer systems. Experiments were carried out under a variety of conditions using domestic sewage

Sewer losses and interactions with groundwater quality.

The incidence and condition of "critical" sewers in the UK are identified together with chemical and bacterial methods of quantifying I/E and its potential impact on sewer performance and on urban groundwater pollution.

Bank filtration: a suitable process for the removal of iodinated X-ray contrast media?

Instationary conditions during the sampling period indicate that, at least under anoxic conditions, a large part of the contrast media and transformation products, which are still iodinated, may be associated to colloids and/or humic material.

Exfiltration from gravity sewers: a pilot scale study.

The exfiltration was governed by the development of a clogging zone at the sewer leak and could be characterized by a leakage factor and may then be used to estimate the risk of groundwater pollution from a sewer network.

Quantification of sewer leakage: a review.

Pressure tests and tracer methods are identified to have the highest potential for decision support in rehabilitation planning and might play a key role in integrated sewer management.

Integrated failure forecasting model for the strategic rehabilitation planning process

The occurrence of pipe failures in water networks cause major technical, economic and socio-economic impacts. Thus, comprehensible and reliable failure prediction models are required for operational

Monitoring of carbamazepine concentrations in wastewater and groundwater to quantify sewer leakage.

The results from this study carried out in Linz, Austria indicate an average exfiltration rate of 1%, expressed as percentage of the dry weather flow that is lost to the groundwater on the city-wide scale, which is lower than sewage losses reported in most other studies which attempted to quantifyExfiltration on the basis of groundwater pollution.

Integrated modelling for the evaluation of infiltration effects.

The general design of the integrated model and its data requirements are presented and the consequences of the simulations are discussed with respect to the prioritisation of rehabilitation activities in the network.
