Intelligent Water Leak Detection Technology and ICT-based Water Leak Management Systems in Uttarakhand and Rajasthan


Title : Intelligent Water Leak Detection Technology and ICT-based Water Leak Management Systems in Uttarakhand and Rajasthan

Period : 12 months (2022)



The Asian Development Bank’s Technical Assistance project introduced an intelligent water leak detection and ICT-based water management system in Uttarakhand and Rajasthan. Running for 12 months in 2022, the initiative targeted Jodhpur and Dehradun, aiming to modernize leak detection through IoT, AI, and cloud technologies.


Project Objectives

The objective of project was to conduct a comprehensive feasibility study on the implementation of an intelligent water loss management system across selected sites in Jodhpur and Dehradun by integrating modern technologies such as IoT, AI, and cloud services, the initiative sought to enhance the capacity of local water management teams through pilot projects. These efforts were aimed at significantly reducing water loss and carbon dioxide emissions, thereby improving the efficiency and sustainability of water resource management in the targeted cities.


Execution Highlights

  • Kick-off and on-site assessments commenced in April, laying the groundwork for successful project deployment.
  • The project provided advanced devices, including 8 sets of Sonic M1 and 13 i-Loggers, facilitating precise data collection.
  • A NELOW server was established, incorporating web and application servers for comprehensive data management and accessibility.
  • Over 30 individuals were trained, strengthening local expertise in using the new technology for water management.



  • Data collection included 275 leak sound data points, alongside water flow and pressure data, enabling the detection of 16 suspicious leak points.
  • The project achieved an estimated annual water loss reduction of 43,800 cubic meters and a carbon reduction of 20,940 kg.
  • Capacity building was conducted, involving 30 people across three official training programs, enhancing the community’s ability to manage water resources effectively.


Intelligent water loss management system pilot project in Binh Thuan, Vietnam


Title : Intelligent water leak management system pilot project

Period : May 2021 ~ Nov 2021



The Binh Thuan province in Vietnam has been facing significant challenges with water loss, leading to reduced availability of clean water for its residents. To address this issue, the pilot project was carried out to develop and implement an intelligent water loss management system in the province. The system aimed to detect and locate leaks in the water distribution network using advanced technology, ultimately reducing water loss and improving water resource management in the region.

The pilot project in Binh Thuan Province, Vietnam is an initiative aimed at developing and implementing an intelligent water loss management system. The system incorporates advanced technologies such as mobile acoustic IoT sensors, pressure data loggers, and ultrasonic flow meters to detect and analyze water leaks in the network. The project is designed to reduce water loss and improve the efficiency of water resource management in the province.


Pilot project execution

The project began with the construction of the NELOW server and implementation of the software, followed by the upload of GIS data to the system. The next phase of the project involved the inspection of water leaks at 3,330 points in the distribution network using mobile acoustic sensors. Unlike previous methods that required professional staff to conduct leak detection, the project used local non-professional individuals who were trained in the use of the mobile sensors. This approach not only increased the efficiency of the process but also provided employment opportunities for the local population.

As a result of the leak detection works, a total of 15 water leak points were detected in the distribution network. These leak points were then repaired, leading to a significant reduction in water loss and improvement in water supply for the local population. Furthermore, water flow measurements were conducted to validate the performance of the water loss reduction measures implemented.

Through the implementation of the NELOW system and various water management exercises, a total of 188,340 cubic meters of annual water loss was saved. This reduction in water loss led to improved water resource management, ensuring the provision of clean and safe water to the community.

The success of the project was largely attributed to the NELOW server construction and software implementation, which allowed for the efficient management of water resources and the detection of water leaks. In addition, GIS data was uploaded to NELOW, allowing for better visualization and analysis of water resource data.

One of the unique features of this project was the use of non-professional local people for water leak detection using mobile acoustic sensors. This approach not only provided employment opportunities for the local community but also helped reduce costs and improve efficiency in water resource management.
