REGIDESO (Burundi)

2018


Setting up a GIS specialized in drinking water network management with GPS solution


 

Context


In this World Bank financed project, Altereo, in partnershop with D2E, was selected by the REGIDESO to set up a GIS with GPS Solution for drinking water network metering in the city of Bujumbura, capital of Burundi.

Altereo was expected to provide the following:

  • The complete Cart@jour® GIS licence with a module for GPS import/export
  • Microsoft server for Windows 2008 with SQL Server express
  • Windows 7 PC and connections
  • Colour A3 Printer
  • 3 bi-frequence GPS Trimble receptors with tripod and stand

 

Project Description


Cartographic data were recovered and integrated, especially background maps and a part of the network with the main structuring objects.

The modus operandi selected for this purpose takes into account the fact that the GPS station closest to Bujumbura is situated at a distance of 130km. In order to improve the precision of the topographic surveys, it was decided that a differential mode would be used with a local or base station installed within the REGIDESO.

This functions together with the measures taken by the technicians with their receptors. A differential correction was applied to the collected data. The creation of this local station necessitated the measurement process from a geodetic point located at Bujumbura Airport.

 Once the measurements are taken, the base can be installed definitively at the premises of REGIDESO within an obstacle-free zone – for example the roof or an abandonned water tower.

Drinking Water Supply and Wastewater Master Plan for Santo Antão and Feasibility Study on the Sanitation Project for Porto Novo, Cape-Verde


Study of water resources
Training of ANAS staff

 

Context


Altereo was awarded this contract financed by the French Development Agency together with the Senegalese firm EDE.

Despite a limited surface area (779 m²), the island of Santo Antão, located to the North-West of the archipelago, is characterized by significant imbalance in the availability of resources between the north and the south of the island.

The South is subject to a very dry climate regime that has forced the concerned authorities to resort to seawater desalination to supply the main city of Porto-Novo (10,000 inhabitants).
On the other hand, abundant rainfall in the northern part of the island provides a sufficient resource through boreholes and springs.

The objective of the Master Plan is to assess the needs of the sector, to define the priority investments to be made and to prioritize them over a 20-year horizon in order to ensure a sustainable service to the island’s populations.

Project Description


As part of this study, ALTEREO is in charge of the following activities:

Study of water resources in order to prepare the water balance (needs/resources) and propose scenarios for resource mobilization to respond to the demand for water within the given horizon
Development of a data model on current and projected water resources and water and wastewater systems (using QGIS) and development of thematic maps.

Training of ANAS staff and the staff of water and sanitation services (SAAS) of the 3 municipalities of Santo Antão to use QGIS.

H2S gases

Context


SEURECA, the consulting and engineering branch of Veolia, requested the service of Altereo to address a civil-engineering related issue at the SPRET (Effluent pre-treatment plant with a capacity of 2,500m³/h). The plant is located in Tangier, which has a population of one million.

The mission comprises a detailed diagnosis of the civil engineering together with the definition of technical specifications for the rehabilitation works leading to call for proposals for the performance of the plant.

Given the complexity of the subject matter, SEURECA asked Altereo to begin by carrying out a preliminary reconnaissance visit.

 

Project Description


This first short-term mission comprised taking into account the issue of visition the facility to meet the partners, namely AMENDIS (a subsidiary of VEOLIA), operator of all facilities within Tangier, and LPEE (Moroccan structure and material laboratory).

The degradation of the facilities is linked to very high concentrations of H2S gases (up to 300 ppm during midsummer). This gas is present in confined structures such as those of the SPRET, and is oxidized to sulfuric acid H2SO4 by chemical means but mainly by biochemical means.

On the Tangier facility, the concrete is leached and completely disintegrates under acid attack, sometimes passking through a thicknesses of more than 30 mm. Most of the epoxy resin or hydraulic binder coatings on the vertical walls of some structures have been completely destroyed and the lower reinforcement beds of the roof slabs are visible.

With its 1,500,000 inhabitants, 1800 km of water mains, 270,000 service connections and an annual water supply capacity of 145 million m³, Phnom Penh, the economic and political center of Cambodia, possesses an extremely efficient water supply system. Whilst the average non-revenue water level is more than 25% in France, for instance, it doesn’t exceed 6% in Phnom Penh. The city has become a leading example in Asia in this respect.

Within the framework of the “Greater Phnom Penh Water Supply System” project, which aims to structure water service within the metropolitan area, PPWSA acquired the service of Altereo informatique to set up a GIS for the management and capitalization of the information relating to drinking water production and distribution infrastructures.

 

Project Description


KIS Water is a ‘full web’ solution offering the whole feature panel traditionally proposed by desktop GIS software. KIS Water provided the PPWSA managers and operators with a complete ‘water supply’ toolbox, ranging from navigation and topology features to the management of workflows.

Furthermore, KIS Water is expected to be a turnkey solution delivered to PPWSA. In addition to this, KIS Admin is an additional module for customisation. GIS specialists and system administrators will have a simple and ergonomic tool to:

  • model and integrate data,
  • manage users and rights, and
  • set up applications, forms and even workflows

It will allow PPWSA to directly manage the evolution of the system according to new requirements, including data exchange with third-party applications in different formats.

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 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


Côte d’Ivoire is a country in West Africa with a population of about 20 million. Abidjan is the economic capital with about 4 million inhabitants. The high concentration of population in the cities (about 45% urban population), requires the existence of a strong organization, capable of efficiently providing water, sanitation and electricity services.

SODECI has had exclusive responsibility for the production and distribution of drinking water in urban areas in Cote d’Ivoire since 1987, and for the operation and maintenance of sanitation facilities in the city of Abidjan since 1999. It is linked to the State of Cote d’Ivoire by a lease contract.

CIE is a company that transports, exports, imports, distributes and markets electrical energy throughout Côte d’Ivoire and West Africa. It is one of the leaders in its sector on the African continent.

Project Description


SODECI and CIE have respectively equipped themselves with the Cart@jour Water and Sanitation and Cart@jour Electricity and Public Lighting business applications. The two companies would like to have a software allowing to:

  • Seizure of assets in accordance with the rules of the art of a hydraulic / electricity network
  • A use of the GIS that ensures the processes of updating and updating data
  • Having solutions for consulting and updating data in the field
  • Having dashboards and indicators on heritage

For SODECI: Geolocation and inventory of connections and delivery points in connection with subscriber management (Saphyr software)

For CIE: Interfacing with Alstom’s DMS and Infor’s CMMS
