van Daal-Rombouts, P.M.M. (author), de Jonge, J (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)This research deals with the design and implementation of an integrated control for the WWTP of Eindhoven. The control influences the operation of the primary settling tanks and influent pumping station to reduce reduce ammonia peaks in the WWTP effluent. The control takes into account the treatment capacity of the biological tanks, the influent...conference paper 2016

Stanic, N. (author), Langeveld, J.G. (author), Salet, Theo (author), Clemens, F.H.L.R. (author)Drill core samples are taken in practice for an analysis of the material characteristics of concrete pipes in order to improve the quality of the decision-making on rehabilitation actions. Earlier research has demonstrated that core sampling is associated with a significant uncertainty. In this paper, the results of core samples are compared...journal article 2016

Elias Maxil, J.A. (author)This text presents an approach to assess the energy content (flow and temperature) at any point of the sewer system based on the coupling of a stochastic model to predict drinking water demand from households and a model to estimate the temperature distribution in the sewer network. An application example is given where the developed tool is...doctoral thesis 2015

Van Riel, W.A.P. (author), Langeveld, J.G. (author), Herder, P.M. (author), Clemens, F.H.L.R. (author)Decision-making for sewer asset management is partially based on intuition and often lacks explicit argumentation, hampering decision transparency and reproducibility. It is unknown to what extent each information source is appreciated by decision makers. Further insight into this relative importance and into implicit factors, improves...conference paper 2014

(author), Weijers, S. (author)Modelling of the integrated urban water system is a powerful tool to optimise wastewater system performance or to find cost-effective solutions for receiving water problems. One of the challenges of integrated modelling is the prediction of water quality at the inlet of a WWTP. Recent applications of water quality sensors have resulted in the...conference paper 2014

Stanic, N. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)There is still a long way to go in understanding the behaviour of solids in sewers due to the difficulties in obtaining sufficient monitoring data to be able to understand the dominant processes. Laser profilers have shown to be capable of measuring the pipe interior, with a high accuracy, which is sufficient to be able to detect and quantify...conference paper 2014

Stanic, N. (author), Salet, T. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)The principle of structural behaviour of buried concrete pipes is fairly understood, except for how material deterioration affects structural behaviour and performance. Consequently, information on the structural behaviour of deteriorated sewer pipes will contribute to better understanding of the changes in status, which is essential for...conference paper 2014

Spekkers, M.H. (author), Zhou, Q. (author), Arnbjerg-Nielsen, K. (author), Clemens, F.H.L.R. (author), ten Veldhuis, J.A.E. (author)Sewer flooding due to extreme rainfall may result in considerable damage. Damage data to quantify costs of cleaning, drying, and replacing materials and goods are rare in literature. In this study, insurance claim data related to property damages were analysed for the municipality of Aarhus, Denmark. The aim of this paper was to study the extent...conference paper 2013

Combined sewer overflows in urban areas - interpreting and comparing European CSO monitoring resultsAarts, A.L.F. (author), Langeveld, J.G. (author), Ten Veldhuis, J.A.E. (author), Rietveld, L.C. (author)Since the initiation of environmental legislation, monitoring campaigns have been done to estimate the characteristic pollutant concentrations of combined sewer overflow water. Such local campaigns are expensive due to the large number of events which should ideally be followed. This study focused on whether available concentration ranges from...conference paper 2013

Dirksen, J. (author)The study into the influence of (differential) settlement on the functioning of sewer systems was initiated to search for additional criteria to make sewer pipe replacement decisions more sensible. For this Amsterdam was used as a case study. Like many megacities (e.g. Jakarta, Bangkok, Tokyo, Shanghai), Amsterdam is situated in a delta area. As...doctoral thesis 2013

Van Riel, W.A.P. (author), Langeveld, J.G. (author), Herder, P.M. (author), Clemens, F.H.L.R. (author)Sewer systems are capital-intensive infrastructures, requiring appropriate asset management to safeguard serviceability. In the Netherlands, effective sewer asset management is described by De Leeuw’s control paradigm. Reliable data and information are key elements in decision-making for rehabilitation and renewal of the assets. Rehabilitation...conference paper 2012

Stanic, N. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)Asset management is a prerequisite for maintaining the required level of serviceability of urban drainage systems. The required asset management effort to achieve a certain level of service is unclear due to sewer systems process and structure complexity. One of the main questions of asset management is what kind of information is needed, and...conference paper 2012

Velez Quintero, C.A. (author)In this research a considerable amount of scientific evidence had been collected which leads to the conclusion that the urban wastewater components should be designed as one integrated system, if the protection of the receiving waters is to be achieved cost-effectively. Even more, there is a need to optimize the design and operation of the...doctoral thesis 2012

Schilperoort, R. (author), Hoppe, H. (author), Haan, C. (author), Langeveld, J.G.

Schilperoort, R.P.S. (author)The wastewater system in the Netherlands comprises approximately 100,000 km of sewer pipes and more than 350 wastewater treatment plants (wwtp). The system collects and treats the majority of domestic and industrial wastewater. A small amount of untreated wastewater, however, is occasionally discharged to rivers and lakes, often resulting in a...doctoral thesis 2011
