SMART VALVES
system design incorporates two circuits with fully automated , smart control of the valves : 1 . Main line : Open for high demand / consumption periods 2 . Bypass line : Open for low demand / consumption periods
This smart system self-adjusts within given pressure parameters , continuously optimising the network ’ s performance regardless of demand quantity or time of day . The result is a water supply system that maintains the required pressure while minimising leakage around the clock . Figure 1 illustrates the concept of flow-modulated outlet pressure control with smart device integration . This sophisticated setup allows for real-time adjustment of pressure based on flow demands , ensuring optimal pressure management throughout the system . To validate the effectiveness of this smart valve control system , we designed a comprehensive test bench setup that simulates various scenarios typical in municipal water supply networks . This experimental arrangement allowed us to measure and analyse the system ’ s performance under different demand conditions , providing valuable insights into its leakage reduction capabilities . Figures 2 and 3 provide an overview of the test bench layout and equipment used in our simulation . The setup includes smart valves , flow metres , pressure sensors and control systems that mimic real-world conditions . This configuration enables us to accurately assess the performance of the smart valve control system in managing pressure and reducing leakage . Figures 4 and 5 demonstrate the system ’ s ability to adapt to varying demand scenarios . During high demand periods , the main line remains

open to ensure adequate flow and pressure ( Figure 4 ). Conversely , during low demand periods , the system automatically switches to the bypass line ( Figure 5 ), which allows for finer pressure control and maximises leakage reduction . This adaptive approach ensures that the water supply system maintains optimal pressure levels at all times , effectively reducing leakage without compromising service quality or system responsiveness to changing demands .
Quantifiable benefits and savings
The implementation of smart valve control systems for leakage reduction offers significant benefits in terms of water conservation and cost savings . While specific calculations depend on factors such as system characteristics and local water prices , our experience shows that the return on investment ( ROI ) is typically achieved within months . To assist water utilities in evaluating the potential impact of smart valve control systems , we have developed calculation data sheets in collaboration with the engineering department of SAMSUN Makina Sanayi . These tools allow for precise estimations of water savings , cost reductions and ROI for specific areas .
Conclusion
Smart valve control systems represent a significant advancement in pressure management for municipal water supply networks . By combining flow-modulated pressure control with real-time data and automated valve operation , these systems offer unparalleled flexibility and efficiency in reducing water leakage . As water scarcity becomes an increasingly pressing global issue , the adoption of such innovative technologies will play a crucial role in conserving this vital resource . Water utilities looking to optimize their networks and reduce losses should consider implementing smart valve control systems as part of their comprehensive water management strategy . For those interested in exploring this solution further , we have developed a pre-fabricated stack system , designed to fit within a standard 40-foot container . This turnkey solution allows for easy transportation and implementation , making advanced pressure management accessible to water utilities worldwide .
