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.
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.

The objective of these training sessions was to give Reunion Island water utility managers a complete vision of the issues and technical solutions within their reach to improve performances and implement real asset management strategies.
Above all, it was a question of giving them the keys to engage in a process of continuous improvement to master asset knowledge up to the optimisation of its replacement in order to achieve high levels of technical and economic performance of their drinking water services.
Communauté de Communes de Zou (Benin)
Study for the Preparation of a Global Strategy for Water Sector Management and Climate Change Adaption in the Department of Zou
The department of Zou was settled following the drainage of the Ouémé River and one of its tributaries and is therefore regularly impacted due to flooding and water runoff. The outcome of this has been:
- Damage to public and private infrastructure to varying degrees
- Material losses as well as the loss of human lives
Altereo was selected to carry out a study at the scale of the 9 communes making up the departmental territory of the Communauté de Communues du Zou (CCZ) with the objective of addressing the issues of stormwater and river flooding and other related consequences in the context of changing climate patterns for an overall management strategy.
The human component was a priority for this project having the goal of protecting all concerned individuals against the risks of runoff and floods while at the same time protecting their economic activities and the structures.
Given the scale and complexity of the project, an iterative approach was required bringing together:
- The elected officials of Zou (CCZ)
- Representatives of the State
- General Directorate for Sanitation
- General Directorate for Water (DG Eau)
- Delegation for Territorial Development (DAT)

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
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.
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.

SEURECA VEOLIA Marocco
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
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.
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.

Technical and methodological audit of the NRW managment service
Recommendations and investment plan
4 180 km water networks
The Kingdom of Bahrain is a country where potable water mainly comes from desalination and is hence costly to produce. Water distribution over the whole country is ensured by the same network which comprises about 3,700 km of mains in 2006 and grows to 4,180 km in 2020. The network is characterised by low pressures which rarely exceed 2 bars.
Altereo assists the Electricity and Water Authority to evaluate its performances in terms of Non-Revenue Water (NRW) management.
Altereo’s is distinguished in two distinct projects:
- the first project carried out in 2006
- the second project carried out in 2019-2020
The first project consists of the following phases:
- Technical and methodological audit of the waste control unit
- Feasibility study for remote network monitoring
- Benchmarking of different leak detection technologies including gas
This project produces a series of strategic recommendations for EWA.
The second project consists of evaluating the actions undertaken by EWA and the stages reached in order to continue to improve performances.. It consists of the following phases:
- Preliminary audit of EWA’s achievements and performance since 2006
- Non-Revenue Water deeper audit to investigate the previous findings
2009 + continuous improvement

Developing a “Full Web” system
Data migration without service interruption
3 646 km drinking water networks
4 157 km waste water networks
7 697 km electricity networks
The project is the deployment of a large-scale IT and GIS solution with expectations matching the stakes of the missions entrusted onto LYDEC.
Since the 1st of August 1997, LYDEC is awarded a 30-year contract for the management of electricity, drinking water and sanitation service distribution for 4 million inhabitants of the Greater Casablanca.
LYDEC has 3,250 employees with an annual turnover of 375 million Euros.
In 2007, LYDEC chose Altereo to supply and implement business SIG applications for Water Supply, Sanitation, Electricity and Street Lighting in fullweb mode.
LYDEC’s is the largest sector-specific GIS deployed on the African continent with 600 end-users.
The LYDEC GIS project is based on a server technology allowing every end-user to benefit from the geographic perspective according to the requirements of his tasks. In this regard and in order to create interaction between the future GIS and the other applications within it’s IT environment, LYDEC chose to manage its technical data in an uniform standardised environment, open and matching the state of the art of geographic information systems.
Beyond the technical challenges is the question of offering a necessary day-to-day tool for a water and electricity utility of this scale to allow it to properly supply vital services to the population and preserve natural resources with maximum performance.
Phnom Penh (Cambodia)
Setting up a Water sector GIS for PPWSA
Phnom Penh Water Supply Authority
Defining a GIS data model + data integration
Reorganising service process
Training staff and users
2 450 km of water supply networks
+ 140 km of additional network per year
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.
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.

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
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.
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.
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
