Break prediction models can help water utility decision-makers to build pipe rehabilitation programs. For many years, using them has been a specialist matter. After more than 15 years of research into the ageing pipes, Irstea (formerly Cemagref) developed Linear Extension Yule Process (LEYP) model based on counting process theory, which relies not only pipe's characteristics and environment but also its age previous breaks. It was then decided develop break tool usable by utilities: ‘Casses’...
An objective of infrastructure asset management drinking water network is to minimize risks (service outage or disruption vehicular traffic). However, there are several methods assess their frequency. This paper first discusses the different models used in predicting structural deterioration because it a compulsory preliminary step calculate risk. Risk for service then discussed.

Abstract Drinking water supply networks play an essential role in protecting the human and economic wellbeing of territories they serve. To ensure continued quality service, organisations involved infrastructure asset management (WIAM) need to deal with a number issues related global change. This paper presents results original interdisciplinary foresight approach carried out by group engineering social scientists, partnership stakeholders. The purpose was examine various possible pathways...
Stakeholders involved in the renewal of drinking water pipes almost always use mean ‘lifetime’ values, which are set by an expert based on material type. A common approach to estimating replacement requirements is assume that all same class renewed when they reach age equal their average ‘lifetime’. However, experience shows for type pipes, very different values used, leading inaccurate estimations requirements. Furthermore, notion can lead confusion between ‘financial requirements’ and...

In France, the system of performance indicators defined within relevant regulations does not include relating to pressure, or number connections. So, Irstea and Veolia Water decided create a new water loss designed for use in France that would take into account these parameters. The study was initially carried out at District Metered Area (DMA) level. These analyses showed advantages considering ratio losses connections, but did highlight significant link between levels average pressure....
Abstract Water scarcity is a harsh reality for many regions. As result, reducing losses from water supply systems (WSSs) of great environmental importance around the world. In France, suppliers are legally bound to reduce their WSSs through loss reduction action plans (LRAPs). For these work, they need suit area which applied. Their impacts on bodies (WBs) and environment also be taken into account. This paper explains an innovative approach fulfil objectives. It involves adding two elements...

Abstract At the request of French Ministry for Ecological and Inclusive Transition (MTES) Biodiversity Agency (AFB), INRAE carried out a study focusing on creation national asset knowledge base drinking water networks, operating at Water (WA) scale. Our involved number statistical models. These models combine data relating to network characteristics (gathered from sample utilities) with geographical demographical collected all municipalities in France. The SISPEA database, along GIS covering...
Optimiser le renouvellement et les performances des ouvrages reseaux qui maillent territoire reste un enjeu majeur pour une gestion patrimoniale infrastructures en pleine evolution. A travers l'analyse transversale de l'organisation acteurs impliques dans la differents types d'infrastructures - d'eau potable d'assainissement, hydrauliques, voiries locales d'art l'article permet ici mettre evidence grande diversite configurations existantes leurs implications termes patrimoniale.
Hourly monitored data of several residential and industrial water meters installed in one drinking system the South France are analyzed to identify dynamical features properties. Small customer consumption may be very irregular with no evident time periodicity. As average increases, periodic patterns emerge at daily weekly scale. A general autoregressive integrated moving model is proposed mimic use. Exogenous variables also introduced account for influence on due seasonal trends, holidays,...

En France, la connaissance a l’echelle nationale des reseaux d’eau potable est aujourd’hui parcellaire. L’obligation pour les services d’etablir un descriptif detaille constitue une opportunite ameliorer et ainsi favoriser mise en oeuvre l’evaluation politiques publiques de gestion patrimoniale potable. Dans ce contexte, l’Agence francaise biodiversite mandate l’Institut national recherche sciences technologies l’environnement l’agriculture (Irstea) construire dispositif permanent...
