Nieuwenhuis, E.M. (author), Post, J.A.B. (author), Duinmeijer, S.P.A. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (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

Meijer, D.H. (author), van Bijnen, J.A.C. (author), Langeveld, J.G. (author), Korving, J.L. (author), Post, J.A.B. (author), Clemens, F.H.L.R. (author)Underground water infrastructure is essential for life in cities. The aging of these infrastructures requires maintenance strategies to maintain a minimum service level. Not all elements are equally important for the functioning of the infrastructure as a whole. Identifying the most critical elements in a network is crucial for formulating...journal article 2018

Post, J.A.B. (author)The anterior part of the sewer system consists of a system of gully pots and lateral (house) connections that drain to main sewers. The total length of lateral house connections can be similar to the total length of the sewers they drain to. In addition, there are 7 million gully pots with corresponding lateral connections in the Netherlands...doctoral thesis 2016

Post, J.A.B. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)The performance of lateral house connections has a direct impact on sewer serviceability. Despite the potential consequences of a blockage, these components are generally maintained with a reactive approach. As inspection data on the condition of lateral house connections are scarce, this study adopts a statistical procedure to support...journal article 2016

Post, J.A.B. (author), Pothof, I.W.M. (author), Dirksen, J. (author), Baars, E. J. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)Gully pots are essential assets designed to relief the downstream system by trapping solids and attached pollutants suspended in runoff. This study applied a methodology to develop a quantitative gully pot sedimentation and blockage model. To this end, sediment bed level time series from 300 gully pots, spanning 15 months, were collected. A...journal article 2016

van Riel, W. (author), Post, J.A.B. (author), Langeveld, J.G. (author), Herder, P.M. (author), Clemens, F.H.L.R. (author)Operational decision-making processes for networked infrastructure management often occur as a multi-actor planning problem, implying these are based on negotiations between different stakeholders in addition to available system quality information. As such, does more accurate data about actual structural condition lead to other or better...journal article 2016

Post, J.A.B. (author), Pothof, I.W.M. (author), Ten Veldhuis, J.A.E. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)It remains unknown how lateral house connections affect the performance of the sewer system, since the assessment of serviceability is mainly based on the state of the main sewer system. Further insight into the contribution of lateral house connections to the overall level of service provided can aid to target investments to parts of the system...conference paper 2014
