“The method provided by Altereo is now the reference basis for our assets”

Christian CLÉMENT, director


Preparing pricing basis to prepare for the updating of water and sanitation service assets inventory

In 2010, in anticipation of the creation of the Eau du Ponant SPL, Brest Métropole began work on reconstituting a database of its fixed assets, enabling the local public company to manage its depreciation and provisions in accordance with accounting rules. In particular, was necessary to reconstitute a financial database from the technical databases of the community to reconstitute its original value for each section of the network and to deduct its net book value. Altereo employees undertook this task with professionalism and with positivity. They explored our archives and prepared a methodology for modeling historical costs. This method has been validated by the Treasurer and is currently the reference basis for our assets.

“I would like to thank you for the quality of the training and the pedagogy”

Jean-Marc GOARNISSON, head of drinking water and sanitation services (SEA)


Training for the staff of the Departmental Council on mini water cycles – from resources to network and infrastructure asset management comprising of technical and financial aspects

From the entire team of the SEA, I would like to thank you for the high quality training and pedagogy employed by Altereo while explaining a complex subject in a span of 3 days!! Bravo for having mobilised a team of experts to provide us with the keys for understanding and for highlighting the areas needing attention while monitoring studies and projects on drinking water. We can now collectively lead by example on how to avoid running into the “wall” and aim towards “just” pricing of water for intergenerational solidarity! Thank you again and see you very soon for more Finistrian studies.

2018


Study on the optimisation of pipeline replacements with HpO® within the framework of a drinking water supply master plan


Application of an inovating system based on Artificial Intelligence

45 network replacement projects

 

Context


The City of Noumea selected the Thésée Ingénierie (subsidiary of Altereo in New Caledonia) – SAFEGE – Altereo consortium for preparing the drinking water supply master plan.

Altereo participated, among others, specifically in the asset management component for optimizing the pipeline renewal programme. For this, the HpO® system based on artifical intelligence was applied.

The City of Noumea has a well managed asset dataset and network leak history for the past 18 years. This high quality data has thus helped demonstrate the power of the HpO® predictive model.

 

Project Description


45 network replacement projects have been planned for the coming 20 years.

They represent around 35 km of networks. It is recommended that the work program be updated and adjusted every 2-3 years based on renewed data enriching the model and the evolving local priorities.

Study and support in the modernisation of the management techniques to improve the water supply service


Deployment of  Cartajour Water Supply GIS
Setting up an autonomous GIS team within the water utility
Optimised water network replacement strategy using the SIROCO® expert system

750 km of networks

 

Context


Nha Trang, The Government of Vietnam has set forth a target policy to phase out subsidies to water supply services. Decree 117 has granted the financial autonomy to water supply companies to stimulate the development of their financial independence. To achieve this target, the water supply companies need to modernize their management techniques to reduce their operating costs and design more cost-effective investment program. The project will provide tools to the beneficiary to improve the water supply system efficiency.
The project is implemented in 3 phases:

  • Phase 1: Institutional analysis – Needs assessment – Preparation of technical specifications
  • Phase 2: Design and implementation of the GIS – Provision of training courses
  • Phase 3: Use of the GIS for asset management and preparation of investment plan

 

Project Description


The project implementation comprised the following three phases:

  • Mission A: Assessment of the beneficiary’s needs in terms of GIS
    Survey of the water supply service organization, the available data and the workforce competence; redaction of the specifications for the implementation of the GIS during the project
  • Mission B: Implementation of the GIS and data acquisition
  • Mission C : Elaboration of an optimized investment strategy for network rehabilitation

Detailed study to establish an optimised network rehabilitation program, SIROCO®

Modelling of the impact factors causing interventions on the network and prediction of future breaks

Multi-criteria analysis for several criteria in terms of reduction of breaks impact on the network

Pilot asset management project for PIPDA (Anvers Province) networks with the joint support of KANEW and SIROCO®


Pilot project on 937 km of networks
Projection and long-term planning for the 50 upcoming years with KANEW
Short-term programming with SIROCO®

 

Context


Following the International Water Association’s reference conference on wealth management, LESAM 2009 in Miami, Altereo and its partner Baur+Kropp were among the six organizations worldwide invited by the Dutch research center KWR to present their wealth management solutions. The aim was to participate in a workshop gathering the 10 water utilities of the Netherlands, as well as water utilities from Northern Belgium. Altereo and Baur+Kropp presented a joint approach for optimised planning of short- and long-term renewal through the application of their respective expert systems SIROCO® and KANEW®.

This approach appealed to the Belgian operator PIDPA, which operates no less than 12 500 km of drinking water networks and 2 500 km of wastewater networks in the province of Antwerp. PIDPA proposed to Altereo and Baur+Kropp to carry out a pilot project on its network.

 

Project Description


The pilot project was framed by three workshops:

  • Workshop to explain the methodology for identifying data
  • Workshop to present preliminary results, reframe the approach and refine the analysis by completing the data and hypothesis formulation
  • Feedback workshop with the results on the pilot area, conclusions and recommendations for wide application

The specific results on the pilot area were as follows:

  • Failure prediction for all sections of the pilot area
  • Short-term renewal programming with SIROCO® which targeted critical pipes according to performance objectives
  • Visibility on long-term renewal efforts with KANEW®

The pilot project has given full satisfaction to PIDPA, which has integrated the recommendations of Altereo and Baur+Kropp and is preparing the next steps in the consolidation of its asset management.

Context


The project aimed to define strategic orientations for the future in order to continue with the improvement of the distribution network efficiency for the city of Fez, so as to reach 75% by 2015 and 80% by 2020.

Description du projet


The network’s initial yield is close to 60%, thanks to an action plan launched in 2002 with an overall budget of Dhs 240 million partly financed by an AFD loan (10 million euros).

  • Mission A: Diagnosis and audit of current performance
  • Mission B: Proposals for improving performance
  • Mission C: Reorganisation of the operations activity
  • Mission D: Preparation of a yield performance maintenance chart

 

Focus étude des défaillances de branchement


Altereo observed:

  • A very high number of failures, exceeding the repair capacity
  • The preponderance of failures on connection elements
  • Among these, a 50% breakage or cracking rate of the PE pipe of the connection

Altereo recommended:

  • A sampling campaign during repairs and laboratory analysis
  • Precautions for storage of PE rolls and installation of new connections
