National Water & Sewerage Corporation / Kampala (Uganda)


Deployment of the HpO® Artificial Intelligence system to improve the efficiency of the Kampala water supply network



National Water & Sewerage Corporation (NWSC) is the public entity responsible for water services in over 250 municipalities in Uganda. The project covers the capital city of Kampala, which is operated by a sub-entity of NWSC, Kampala Water.
The drinking water network under the study consists of several thousand kilometers of pipes. The ageing of the networks, which were first laid in 1930, is affecting the performance of the drinking water supply.
The rate of unbilled water (NRW) is 40%. The share due to leakage is estimated at over 20%, or 75,000 m³ lost per day. Kampala Water repairs 4000 leaks per month, with no significant improvement. These are only visible or easily identifiable leaks.
The rational and targeted renewal of the network is thus a major challenge for Kampala Water. Altereo has therefore proposed an expert approach to network asset management based on its patented and award-winning HpO® artificial intelligence technology.
The project is funded by the French Ministry of Economy & Finance through the FASEP scheme.


Project overview

The project lasts 18 months and is divided in 2 main missions:

  • Mission A : Understanding and data improvement
    An essential step with the deployment of the HpO Collect® mobile application for field agents.
  • Mission B : Optimised network renewal programme
    Valuation of network failure data by HpO® artificial intelligence to predict the future risk of failure and to target and optimise leakage detection and network replacement.


Description of the mission

Mission A : Understanding & Data improvement (1 year)

Phase 1 : Understanding the context and the organisation (6 months)

The project starts by understanding the context of NWSC/Kampala Water in terms of existing practices, processes, skills, IT tools and data:

  • Understanding focused on the asset management and leakage control team
  • Familiarity with the leak detection and repair unit
  • Analysis of existing software, in particular the Geographic Information System (GIS)
  • Audit of existing data and measurement of discrepancies with the prerequisites for the implementation of HpO® AI

Phase 2 : Improvement of data describing networks and anomalies (6 months)

Existing knowledge about the network and its failures needs to be strengthened before any analysis can be made. It is necessary to have complete knowledge on two aspects:

  • Pipes (diameter, length, materials, installation or laying date)
  • Failures (date, location, type of anomaly, reason)

Data improvement work is done in collaboration with Kampala Water at 3 levels:

1. Field surveys and investigations to recover missing information

2. Deployment of the mobile application HpO® Collect

HpO® Collect has been specially designed to ease the collection of relevant data at the time of leak repair.
In less than a minute, HpO® Collect enables the field agent to collect data about the failures of mains, service connections and fixtures: GPS location, material, diameter, type of leak, cause, photos, etc.
The data capitalised by HpO® Collect is stored in a secure database which will be used for visualisation and simplified analysis.
The richer the history of failures, the better the asset is known and the more it will be possible to optimise the replacement strategy. Once a sufficient amount of failures has been collected, Altereo will be able to implement the rest of the HpO® approach, including the use of artificial intelligence to predict the risk of failures in the future.

3. Deployment of the HpO® Citizen mobile application to the population

Altereo also plans to deploy a public application that will allow the population to instantly report to Kampala Water any leaks visible on the public domain.

4. Support for updating the missing networks in the GIS

The mapping of the pipes in the geographic information system is not exhaustive. Only 3,000 km of pipes have been digitalised to date. Altereo will identify the sectors where the networks are not digitised in the GIS. Altereo will then oversee Kampala Water’s teams to survey the networks in the field and complete the GIS. This process will be continued over time by Kampala Water.

Mission B : Change management and asset replacement programme

Phase 1 : Implementation of a renewal programme on the Kampala network

During the second year of the project, after having upgraded the descriptive data of the drinking water network and built up a exploitable stock of failures, Altereo will be able to implement the rest of the HpO® approach, including the use of artificial intelligence to calculate the risk of failure in the future.

The benefits of this innovative approach are:

  • Optimising leakage search and detection
  • Targeting the pipes to be replaced as a priority
  • Drastically increasing the efficiency of the renewal budget

Kampala Water will therefore be able to significantly optimise its operations and investment programmes based on the results provided by HpO®. These results will be able to be articulated with pipeline replacement projects for which financing has already been secured from the AFD (French Development Bank).

Phase 2 : Capacity building and sustainability of skills

In parallel with the renewal programme, Altereo, in partnership with Watura, will provide Kampala Water and NSWC with an e-learning platform that will enable them to follow the training sessions. The training & capacity building programme in English will include the principles of asset management and water system performance, the importance of the key phases of the project and the use of the HpO® module interfaces left at Kampala Water.

REGIDESO (Burundi)


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



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.


Agence Nationale de l’Eau et de l’Assainissement (Cape Verde)


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



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.

Detailed diagnosis of the civil engineering aspects and definition of technical specifications for the rehabilitation works of the SPRET

Diagnosis of the civil engineering

Effluent pre-treatment plant with a capacity of 2,500m³/h
H2S gases


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.


National Authority for Drinking Water and Sanitation (DINEPA)

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



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®

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.

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
