Engagés pour l'eau et l'assainissement urbains

The specific objectives of the ODP

• Determining and quantifying the unaccounted for water and making proposals for reducing it by means of a strategy based on a cost/benefit analysis
• Assessing the organisational structure of SANESUL and making proposals for corrective measures where necessary.
• Defining of a management control system for the supervision and monitoring of water distribution systems.
• Proposing standards and recommendations for management in the operational and commercial sectors in order to improve customer service.
• Implementing a training program for the technical managers of SANESUL for effective and rapid transfer of technology.

The 5 phases of the project

Phase 1: Diagnosis

1A: "Non-Revenue Water" diagnosis

1B: Structural and organisational diagnosis

Phase 2: Development of an Action Plan for the reduction of losses in pilot zones

• Appropriateness of macro-metering
• Analysis of customers with meters
• Survey of users and connections
• Leak detection campaign
• Field survey on the influence of the metering index
• Survey on the variation in the number of meters installed
• Survey on the zones that have no water and on the repercussions for the loss index
• Survey on large consumers
• Survey on connections considered as inactive or disconnected for non-payment
• Additional survey on large consumers

Phase 3: Implementation of the Action Plan in pilot sites

• Developpement and management of a database relating to loss monitoring
• Appropriateness of macro metering and analysis of the pilot sites
• Visible and invisible leak detection and repair campaign
• Updating of the subscriber database
• Preliminary action to improve operational management
• Optimisation of customer management
• Cost/benefit studies of the actions that have been implemented
• Operation and maintenance manual for the pilot sites
• Assessment of results

Phase 4: Two years Action Plan, based on the results of pilot actions

• Metering improvement plan
• Preliminary sectorisation and operational improvement tasks
• Setting up of a telemetry system
• Field survey on connections and users
• Survey and visible and invisible leak repair
• Additional analyses and final definition of corrective actions
• Organisation of SANESUL
• Structuring of the company's databases and information system for the monitoring and production of non-revenue water
• Definition of an action plan for 2 years

Phase 5: Implementation of a two-year Action Plan

• Training and assessment for the setting up of the macro metering system
• Training and assessment for the setting up of the telemetry system
• Training and assessment for the operation of the information system
• Development of procedure manuals for the five systems in the project
• Technical assistance for the implementation and monitoring of the Action Plan
