GWF BALANCE
Our Unique Approach to Measure and Effectively Reduce Non-Revenue Water.
Reduce Water Network Leakage by 35%*
Water network leakage is one of the most pressing challenges for water utilities. In many regions of the world, 30, 40, even over 50% of the water pumped into water networks is lost through leakage. Growing population, climate change and aging infrastructure are adding to the losses. These are costly losses – and often times costly interventions such as infrastructure replacements are seen as the only way out. BUT: we have shown that it is beneficial to first gain an in-depth understanding of the network quality and leakage levels through data. AND: based on our generated data, we have shown that we can reduce network leakage by 35% – without costly infrastructure investments.
GWF BALANCE Delivers Holistic Insights and Immediate Impact
Only Three Sensors per District Metered Area
GWF BALANCE creates a holistic dataset for a District Metered Area (DMA) with one highly accurate flow meter and two pressure sensors. We are happy to use existing sensors if feasible. No further infrastructure work is required, and no interruptions in service occur.
Significant Savings of Water and Energy
On average, GWF BALANCE reduces current leakage levels by 35%. The economic effect of this reduction is significant: utilities lower their OPEX for water transport and treatment. Associated CO2 reductions can add up to bankable assets.
Optimized Asset Lifetime and Less Friction
GWF BALANCE optimizes network pressure, resulting in fewer mains breaks and less wear on infrastructure components such as pipes, valves, and meters. Utilities can expect an overall optimized asset lifetime, leading to lower maintenance work and expenses.
Sustainable Impact Within 8 Weeks
We have a proven implementation process for GWF BALANCE that provides first insights within a few weeks. After eight weeks, leakage reduction takes effect, and volumetric benefits can be realized. A highly collaborative project delivery ensures lasting impact.
Select and Prioritize Investments Based on Data
Based on the data gathered with GWF BALANCE, you can model different interventions and decide on the right improvement measures per zone and the right priorities for the network. Your capital spend will be more effective, efficient, and sustainable.
Independently Verified Results
The results of GWF BALANCE are independently audited by reputable firms, providing an additional layer of credibility and assurance. This independent verification underscores the reliability of the methodology and the tangible benefits it delivers to water utilities.
GWF BALANCE Follows a Proven 8-Week Implementation Process
Project Kick-Off, Stakeholder Engagement and Platform Setup
Together with you, we organize a full-day workshop to review data, select zones, define measurement points, and agree on the overall project implementation. Based on the project plan, we engage with relevant stakeholders (e.g., fire department) and prepare the platform for the project.
Sensor Installation for Flow and Pressure Data Collection
Our field engineers install the necessary sensors and connectivity for data collection. Over a period of 7–14 days, we collect flow and pressure data from our sensors with high granularity. This data provides all necessary flow and pressure information for input into the GWF BALANCE digital tool.
Determination of the Pressure/ Leakage Relationship (N1 Index)
We monitor the normalized flow and pressure profiles through system-generated data. This allows us to evaluate the pressure-to-leakage relationship, represented by the N1 index. The data provides insights to assess the system performance and determine whether an N1 test is required.
Implementation of Recommended Pressure Settings
Adjustments to the network pressure are recommended and implemented. Existing or new PRVs are set to optimal pressure points accordingly. The GWF BALANCE platform tracks the impact and revalidates recommendations for accuracy and effectiveness.

«The LimnoTech team has evaluated BALANCE and quantified the anticipated volumetric benefits. This solution presents a promising opportunity for water stewardship leaders to collaborate with municipal water agencies to help address the challenge of pressure-related water leakage in distribution systems.»
«BALANCE closes the gap on accessing quick and efficient DMA performance analysis, effectively characterising DMA-level leakage and enabling prioritized and focused leakage reduction strategies with efficient application of leak management resources.»
«By leveraging the power of granular water data, BALANCE empowers utilities to proactively optimize water distribution, significantly reduce losses, and enhance water availability for communities and the environment.»
«GWF BALANCE has helped our customers to identify leakage levels and create significant water savings through optimized pressure management.»
«We are excited to partner with GWF to leverage AI to minimize water loss and
increase water availability in water stressed regions.»
«At SES Water, we carried out a trial of the BALANCE software and approach. I was deeply impressed with the amount of insight that the BALANCE solution was able to give into the trial areas. The BALANCE solution highlighted issues in one DMA with minimum night flows and some interesting and unusual afternoon profiles. The analysis also gave us a far deeper understanding of the unavoidable annual background bursts with the DMAs and the relative infrastructure condition factor.»
