To predict the past in order to know the future

Drinking and wastewater networks have been constructed more than a century ago. They have been built for and by the city. Today or tomorrow, such assets will have to be manage in order to maintain the performance on the sort, medium or long term. Installation date of pipes is one of the major information that needed to be known in order to shift from run-to-failure to proactive management, by predicting the condition of pipes that haven’t been investigated. However, such information is often missing and its reliability is questioned.

The HIREAU research project aims to:

  • demonstrate that it is feasible to reconstitute the missing installation date of pipes,
  • provide utilities with operational methods to reconstitute such data,
  • improve the knowledge of the history of cities and their networks.

HIREAU started in November 2016 for three years and will investigated three different approaches:

  • learning methods in order to predict installation date based on characteristics of the pipes and its environment,
  • consultation of city archives in order to gather data on the existing pipes,
  • in-situ investigations to determine the installation date of a pipe.

The HIREAU consortium is the following:

  • Coordination: Frédéric CHERQUI (DEEP – EA 7429 / University Lyon 1)
  • Laboratories:
    – DEEP (EA 7429) : Pascal Le Gauffre & Frédéric Cherqui
    – EVS (UMR 5600) : Bernard Gauthiez
    – LIRIS (UMR 5205) : Khalid Benabdeslem & Haytham Elghazel
  • The Metropolis of Lyon: Laurence Campan, Gilles Chuzeville, Didier Fangeat, Delphine Petit, Sonia Reeb & Elisabeth Sibeud
  • Industrial partners:
    – Eau du Grand Lyon : David Poinard & Ntissar Tijani
    – Veolia : Sonia Graja & Franck Texier
