Operational optimisation program


The fundamental objectives of the Operational Development Program (ODP) were:

  • Increasing invoicing and debt recovery
  • Reducing the operational costs in the short and long-term

The ODP was put in place in Campo Grande (660,000 inhabitants), Dourados (150,000 inhabitants), Corumba/Ladario (115,000 inhabitants), Ponta Porã (50,000 inhabitants) and Três Lagoas (80,000 inhabitants).


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
