My Service Offering:

It all starts with an initial diagnosis of your losses...

I intervene throughout the entire process and key actions presented above, from identifying losses to implementing concrete solutions to improve your network's performance.

Performance Diagnosis & Audit

A high-performing distribution network ensures efficient resource management and controlled operation. Water is a precious resource, and its transport to users relies on a network subject to losses. Invisible leaks and overflows, intervention delays, under-metering, consumption anomalies, or pipe aging—all these factors impact your network’s performance and generate significant costs.

Diagnosing your network’s performance means better understanding your losses!

A performance diagnosis allows you to:

✔ Locate, characterize & quantify losses
✔ Identify the performance levers specific to your network
✔ Deploy a targeted & optimized strategy

And thus:

✔ Preserve your water resources!
✔ Reduce losses: identify and correct physical and commercial leaks where it matters most.
✔ Optimize costs: cut unnecessary expenses related to lost water volumes, excess energy consumption, and avoidable corrective interventions.
✔ Protect your infrastructure: anticipate network degradation by prioritizing targeted renewal investments.

A thorough diagnosis is essential to determine where and how to intervene effectively.

MY APPROACH

I rely on a proven methodology, aligned with IWA standards, to provide a clear and structured assessment:

Data collection and validation: volumes distributed, pressures, metering, and consumption.
Assessment of physical and commercial losses: identifying leak volumes and recovery potential, analyzing metering errors, billing inconsistencies, etc.
Asset condition assessment: network diagnostics, classification, and buried infrastructure assessment based on key indicators.
Operational practices: reviewing operating procedures and processes to identify performance levers.

Each diagnosis provides a clear view of improvement areas and priority actions to optimize network management.

I support the implementation of key performance levers, including pressure management, network sectorization, leak detection strategy, asset management, and pipe structure diagnostics.

Network Pressure Optimization

Efficient pressure management in water networks is essential to limit losses, extend infrastructure lifespan, and ensure optimal service. Excessive pressure or sudden variations accelerate pipe degradation, cause leaks, and increase breakage rates.

The first step is considering a simple pressure reduction, particularly suitable for small-scale networks. This solution offers several advantages:

Simplified maintenance and lower training requirements
Reduced installation and operational costs
Quick return on investment (ROI)

Although straightforward, this approach enables:

Pressure reduction
Lower leakage rates and nighttime flow rates
Decreased breakage frequency

For larger network areas, pressure modulation may be more appropriate. This approach involves electronic equipment, sensors, and communication systems to optimize pressure reduction while considering daily network variations.

Although more expensive, it offers:

Greater leak reduction through precise pressure adjustments
Pressure stabilization over 24 hours, further reducing leaks and breakages

MY EXPERTISE

I assist you at every stage of your project:

Preliminary study (APS): network analysis and identification of opportunities
Detailed design (APD): sizing, budgeting, equipment selection, fire protection validation, performance impact estimation, and ROI calculation
Technology selection support: guidance in choosing the right solutions
Construction oversight & commissioning: coordination, control, and optimization
Mid-term impact study: evaluation of achieved benefits (leak reduction, infrastructure lifespan extension)

Investing in pressure management ensures a quick return on investment (1 to 3 years) while safeguarding your infrastructure. Let's optimize your networks for a sustainable and high-performing service.

Network Management & Performance Monitoring

Effective network management helps detect leaks quickly and optimize overall performance. The most effective method relies on network sectorization, which divides the system into smaller zones for precise minimum night flow (MNF) monitoring.

MNF is a key indicator of network performance. A sudden and persistent increase usually signals a leak, enabling rapid intervention to limit losses. However, interpreting MNF changes depends on the sectorization level. For example, if the MNF fluctuates between 70 and 85 m³/h, detecting a 1 m³/h leak is nearly impossible. Conversely, if the MNF is stable around 10 or 20 m³/h, such a leak becomes noticeable. Proper sectorization design is therefore crucial.

MY EXPERTISE

A well-designed sectorization requires careful planning and precise calibration of equipment (flow meters, telemetry transmitters, information systems). It is also essential that the entire chain—sector, MNF, flow meter, IT platform, leak detection, and repair—remains consistent and well-integrated. Only when all these components function properly can the full benefits of the investment in network sectorization be realized.

I offer tailored support to ensure optimized network management and effective loss reduction:

Sectorization & macro-metering diagnosis
Network division studies and implementation: designing optimal sector boundaries for improved precision
Step-tests: sector tightness verification, identification of leak-prone sub-sectors, and prioritization of leak searches
Continuous optimization: monitoring leak detection efforts, adjusting parameters, and implementing adapted operational processes

By ensuring consistency between sectorization, measurement, and interventions, I help you maximize network performance, improve ROI, and sustainably reduce water losses.

Network Asset Management

Today, we inherit a water infrastructure resulting from massive investments made over more than a century, in France and worldwide. Managing this infrastructure is a true responsibility, requiring special attention to ensure its longevity, maintain service quality, and preserve resources while preventing costly failures.

The asset management of water networks is essential to maintaining a sustainable and efficient infrastructure. It relies on a thorough analysis of existing systems and enables the planning of necessary renewals to prevent future failures and optimize maintenance costs. Effective management ensures proactive investment planning and maximizes the use of available resources.

Multi-Criteria Analysis for Planning Your Network Renewal:

My approach begins with a multi-criteria analysis of your network's pipelines based on GIS data. This analysis considers factors such as infrastructure age, pipe material, leakage rates, and other key criteria to establish renewal priorities. This method helps identify the most critical elements and address them first to prevent costly failures and minimize service disruptions.

Tailored Renewal Plan:

Once the analysis is complete, a renewal plan is developed, taking into account priorities as well as budget constraints, which involves a precise cost estimation of the renewal work. Network adaptations may be implemented to maintain water supply during the works, such as the installation of temporary above-ground networks. Specific measures are also planned to preserve water quality, particularly by mitigating the effects of flow reversals through a flushing program. This approach helps minimize the impact of the works on users while ensuring service continuity.

Correction of Erroneous Data:

GIS data can sometimes be inaccurate or outdated, leading to errors in renewal planning. In such cases, two options are available:

Minor corrections and removal of erroneous data from the analysis – A quick approach, but the study will not cover the entire infrastructure, which may require a separate analysis.
In-depth data corrections to improve the accuracy of the analysis and planning – More time-consuming but provides greater precision and enhances your asset management efficiency.

MY EXPERTISE

I support you in the optimized management of your buried assets by offering tailor-made services to ensure the long-term sustainability of your infrastructure:

Existing Asset Diagnosis: Assessment of network condition based on GIS data, including correction of erroneous information.
Development of Renewal Plans: Creation of plans based on multi-criteria analysis to establish renewal priorities.

Water for All

Improving access to safe drinking water for the most vulnerable populations has always been one of my primary motivations. I had the opportunity to lead a World Bank-funded project in Jakarta, which connected over 5,000 underprivileged households to the water supply network. This project marked a major milestone with the first official connections in the informal settlement of Muara Baru, a neighborhood that had existed for decades without legal access to water due to land and regulatory constraints.

MY EXPERTISE

I offer my expertise to support this type of project, from design to implementation:

Project Development: Defining objectives, structuring, and assisting in securing funding.
