Modeling Water Distribution Systems - Integration Between SCADA Systems and Hydraulic Network Simulation Models
Riis, Thomas Sjømoen (Master thesis, 2016)The water distribution system conveys water from the water treatment plant (WTP) to the user. A significant amount of the water is lost in the transit. The International Water Supply Association (IWSA) claims that the ... -

Numerical Modelling of Separation Efficiency of Sediments in a Combined Sewer Overflow (CSO)
Wilhelmsen, Berit Bye (Master thesis, 2012)Combined sewer overflows (CSOs) are a part of the combined storm water and foul sewer system. CSOs should protect the downstream sewer system against overloading during heavy rainfall and snow melting. This report investigates ... -
Performance based modelling of long-term deterioration to support rehabilitation and investment decisions in drinking water distribution systems
Bruaset, Stian; Sægrov, Sveinung; Ugarelli, Rita Maria (Journal article; Peer reviewed, 2017)Managing the urban drinking water system in the long term in order to maintain system performance can be challenging due to the difficulty of modelling future deterioration of the networks. This paper establishes a methodology ... -
A Qualitative and Quantitative Assessment of the Long-Term Hydraulic Reliability of Norwegian Water Distribution Network - A Case Study
Simonsen, Andreas Bakken (Master thesis, 2016)Abstract Today, the water utilities in Norway experience ageing and deterioration of assets in their water supply systems. The rehabilitation rate needs to increase in order to avoid a possible lag in renewal. Trends of ... -
Rehabilitation Planning of Water Distribution Network through a Reliability – Based Risk Assessment
D'Ercole, Marianna; Righetti, Maurizio; Raspati, Gema Sakti; Bertola, Paolo; Ugarelli, Rita Maria (Journal article; Peer reviewed, 2018)The efficient and effective management of existing water distribution systems (WDSs) faces challenges related to aging of infrastructure, population growth, extended urbanization, climate change impacts and environmental ... -
Reliability of Watersupply Networks: Case study: Network of Skullerud, Oslo, Nrway
Vangsnes, Vegard Gallefoss (Master thesis, 2012)It is necessary to have an understanding of the reliability of water distribution network, in order to make right decisions on maintenance and expansion of an existing network. The purpose of the master thesis has been to ... -
A Risk-Based Approach in Rehabilitation of Water Distribution Networks
Raspati, Gema Sakti; Bruaset, Stian; Bosco, Camillo; Mushom, Lars; Johannessen, Birgitte Gisvold; Ugarelli, Rita Maria (Peer reviewed; Journal article, 2022)A risk-based approach to support water utilities in terms of defining pipe rehabilitation priorities is presented. In a risk analysis in the risk management process, the probability that a given event will happen and the ... -
Understanding the governance of urban water services from an institutional logics perspective
Franco Torres, Manuel; Kvålshaugen, Ragnhild; Ugarelli, Rita Maria (Peer reviewed; Journal article, 2021)In recent decades, the urban water sector has experienced accelerating social complexity that derives from conflicting goals and beliefs, making the sustainability of the sector primarily a governance issue. However, ... -
Urban water system metabolism assessment using WaterMet2 model
Behzadian, Kourosh; Kapelan, Zoran; Govindarajan, Venkatesh; Brattebø, Helge; Sægrov, Sveinung; Rozos, Envangelos; Makropoulos, Christos; Ugarelli, Rita Maria; Milina, Jadranka; Hem, Lars J. (Journal article; Peer reviewed, 2014)This paper presents a new “WaterMet2” model for integrated modelling of an urban water system (UWS). The model is able to quantify the principal water flows and other main fluxes in the UWS. The UWS in WaterMet2 is ...
