Arnell, V. (author)The paper describes a comparison of calculated storm water discharges with two kinds of rainfall data: design rainfalls developed from intensity-duration-frequency relationships or from measured rainfall data and real measured time series of rainfalls or time series generated by statistical methods. These two rainfall approaches have been...report 1978

Kluck, J. (author)In the near future in the Netherlands many reservoirs will have to be built to abate the pollution of the surface water by overflowing storm water from combined sewer systems [Kluck, 1992-a]. These reservoirs, called storm water sedimentation tanks, reduce the pollution in two ways. The most important is by simply storing a part of the sewage ...report 1994

Langeveld, J.G. (author)Wastewater systems consist of sewer systems and wastewater treatment works. As the performance of a wastewater treatment plant is affected by the characteristics, i.e. operation and design, of the contributing sewer systems, knowledge of the interactions between sewers and wastewater treatment works is very important when trying to understand...doctoral thesis 2004

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

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

(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

Cedillo Galarza, J.S. (author)In order to propose a new sewer inspection method, a velocity/turbidity profiler (Ubertone, UB Flow F-315) has been tested in a laboratory. A 50 m glass flume has been adapted with several lateral connections (with a range of diameters, angles, intrusions, cracks), supplied by a 1 m3 tank. Placed just below the free surface on a rotating (to...master thesis 2016

Wang, H. (author)In the light of the European Work Program DRS-11-2015, a Dutch Collision “Solid City on Soft Soil” was formed in order to mitigate disasters brought by subsidence and safeguard cultural heritage assets. As an initial approach, the Dutch Collision planned to explore and implement solutions for this challenge in the historic city center of Gouda...master thesis 2016

Nieuwenhuis, E.M. (author)Fat, oil and grease (FOG) deposits are one of the leading causes of sewer system blockages, thereby increasing the risks of undesired and polluting flooding and sewer overflows. FOG accumulates throughout the entire sewer network; e.g., in public sewer pipes and lateral house connections it reduces the available discharge capacity, and in pump...master thesis 2016

Langeveld, J.G. (author), van Daal-Rombouts, P.M.M. (author), Schilperoort, Remy (author), Nopens, Ingmar (author), Flameling, Tony (author), Weijers, Stefan (author)Wastewater treatment plants (WWTP) typically have a service life of several decades. During this service life, external factors, such as changes in the effluent standards or the loading of the WWTP may change, requiring WWTP performance to be optimized. WWTP modelling is widely accepted as a means to assess and optimize WWTP performance. One of...journal article 2017

van Nooijen, R.R.P. (author), Kolechkina, A.G. (author)Arguments are presented in favor of modeling sewer systems and in particular Dutch sewer systems as a sampled data system with events. Basic limitations on controlling these systems when ignoring their hybrid nature are stated. The traditional control scheme for the Dutch systems is given as an example of event driven local control. Basic...journal article 2018

(author)The accumulation of FOG (Fat, Oil and Grease) deposits in sewer pumping stations results in an increase in maintenance costs, malfunctioning of pumps and, a potential increase of wastewater spills in receiving open water bodies. It is thought that a variety of parameters (e.g. geometry of the pump sump, pump operation, socioeconomic...journal article 2018

Montes, Carlos (author), Kapelan, Z. (author), Saldarriaga, Juan (author)This paper aims to analyze different sediment self-cleansing criteria and to find out what the corresponding implications are on the optimal design of sewer systems. A methodology based on enumeration is used to find the sewer network design that minimizes the costs of construction while fulfilling a number of design criteria including self...journal article 2019

Jia, Yueyi (author), Zheng, Feifei (author), Zhang, Qingzhou (author), Duan, Huan Feng (author), Savic, Dragan (author), Kapelan, Z. (author)Hydraulic modeling of a foul sewer system (FSS) enables a better understanding of the behavior of the system and its effective management. However, there is generally a lack of sufficient field measurement data for FSS model development due to the low number of in-situ sensors for data collection. To this end, this study proposes a new method...journal article 2021

Zhang, Qingzhou (author), Zheng, Feifei (author), Jia, Yueyi (author), Savic, Dragan (author), Kapelan, Z. (author)Real-time hydraulic modelling can be used to address a wide range of issues in a foul sewer system and hence can help improve its daily operation and maintenance. However, the current bottleneck within real-time FSS modelling is the lack of spatio-temporal inflow data. To address the problem, this paper proposes a new method to develop real...journal article 2021
