An analysis of the potential impact of climate change on the structural reliability of drinking water pipes in cold climate regions
Bruaset, Stian; Sægrov, Sveinung (Journal article; Peer reviewed, 2018)The climate is changing worldwide. For the northern hemisphere there are distinct challenges related to climate change. It is expected that temperature on a general basis will increase within the next 100 years, and that ... -
Assessing the hydraulic performance of a combined sewer system under climate change using temporal downscaling
Munkerud, Malene Yttersian (Master thesis, 2018)In recent years, climate change has lead to an increasing number of high intensity rain events causing flooding in urban areas around the world. Studies of different future climate scenarios indicate that this increase ... -
Bærekraftige strategier for rehabilitering av vann- og avløpsnettet
Rygg, Håkon (Master thesis, 2017)Planlegging av utskiftningsmetoder for vann og avløp bør utføres i et langt tidstidsperspektiv. Enkelte effekter kommer ikke fram i et kort tidsperspektiv, men inkluderes derimot i et langt et. Planlegging av denne ... -
Klimaets effekt på avløpsnettets funksjon og fremtidige klimaendringers forventede påvirkning
Blaser-Erke, Amalie (Master thesis, 2018)Funksjonsevnen til avløpssystemet blir i stor grad påvirket av tilstoppinger i ledningene da de reduserer evnen til å transportere avløpsvann. Blokkeringer kan oppstå på grunn av ulike årsaker, men i denne oppgaven har ... -
Long-term sustainable management of the urban water and wastewater pipe networks
Bruaset, Stian (Doctoral theses at NTNU;2019:101, Doctoral thesis, 2019)Water utilities around the world are facing challenges related to the delivery of safe and secure water and environmental friendly collection and handling of wastewater. One of the main components in handling of these tasks ... -
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 ... -
Reviewing the long-term sustainability of urban water systems rehabilitation strategies with an alternative approach
Bruaset, Stian; Rygg, Håkon; Sægrov, Sveinung (Journal article; Peer reviewed, 2018)It is generally difficult to assess the performance of an infrastructure with a substantially longer life span than economic models can handle, and the life cycle concepts in urban water systems are normally limited 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 ... -
Tilstad av ledningsnett for vann i Norges største byer - Fornyelsesrate
Østervold, Lars (Master thesis, 2018)For å bevare muligheten til å levere drikkevann til forbrukeren er det viktig med et godt distribusjonsnett. For hvert år forvitres nettverket, og dette må kompenseres med fornying av vannrør. Fornying er kostnadsintensivt ... -
Using the multiple scenario approach for envisioning plausible futures in long-term planning and management of the urban water pipe systems
Bruaset, Stian; Sægrov, Sveinung (Journal article; Peer reviewed, 2018)Water utilities are facing the challenging problem of planning rehabilitation and renewal of their urban water systems for an uncertain future, which will be affected by climate change, demographic changes and extensive ...
