GWL Leverages Innovative Technology to Detect Leakages, Curb Water Losses.

Ghana: Ghana Water Limited (GWL) has taken a significant step forward in reducing water losses by launching a specialized Leak Detection Field (LDF) to train staff in modern leakage detection techniques. In partnership with Denmark's Aarhus Vand, the project aims to equip GWL's engineers and technicians with the necessary tools and skills to address Ghana's water loss challenges more effectively.According to Ghana News Agency, GWL currently loses approximately 48 percent of some 324 million cubic meters of water production annually, across the combined 90 urban water systems, due to leakages and system inefficiencies. This loss translates into a substantial financial impact, costing GWL around GH?1.89 billion Ghana cedis annually. The collaboration with Aarhus Vand, facilitated through the Danish Embassy, includes training and resource support to bolster GWL's capacity in leak detection and water loss management.The project marks the beginning of a rigorous practical training framework for GWL's technical staff and a renewed approach in using Danish technology to detect leakages on GWL networks. The Danish partners have shared expertise and best practices, focusing on modern asset management techniques and Geographic Information System (GIS) tools. The pilot project, implemented in Tema under Denmark's Strategic Sector Cooperation (SSC), serves as a proof of concept, demonstrating the efficacy of Danish water loss reduction strategies in Ghana's context.The newly established Leak Detection Field will serve as a practical training ground, allowing GWL staff to locate and repair both visible and hidden leaks in water pipelines. This venture builds upon GWL's existing modernization efforts as the company has recently introduced smart meters that enable remote readings, simplifying billing processes and enhancing accuracy. Additionally, GWL has digitized its commercial business operations, including payment systems, making it easier for customers to pay bills and report issues via their mobile devices.Dr. Clif ford Braimah, Managing Director of GWL, speaking at the launch of the new Leak Detection Field at the Ghana Water Institute, highlighted the critical need for proactive measures in combating water loss using appropriate industry technology for both operational efficiency and the long-term sustainability of the company's services. He explained that unreported leaks, which were often undetected and persisted for years, significantly reduced pressure within the network and hindered the utility company's ability to maintain a consistent water supply to households.Dr. Braimah stated that the initiative targets both visible issues and unseen losses impacting GWL's technical and financial performance. He emphasized that embracing innovative technology was essential to positioning GWL as a world-class utility, capable of meeting the increasing demands of Ghana's urban population. He remarked on the importance of technology and effective water management in making potable water accessible and affordable, urging furt her investments in water infrastructure.He expressed gratitude for the support received from the Danish government and other international partners, including the World Bank under the Greater Accra Metropolitan Area (GAMA) - a Sanitation and Water Project instrumental in advancing Non-Revenue Water (NRW) management. The MD commended the Water Worx Project for its contributions, specifically in providing essential tools to improve the efficiency of GWL's technicians.Mr. Tom Norring, Danish Ambassador to Ghana, who commissioned the Leak Detection Field, stated that reducing water loss improves water service to those without regular access. He noted that low water loss also meant reduced energy consumption, as most of the water traveled more than 50 kilometers before reaching consumers. The Ambassador observed that skilled expertise and technical knowledge were essential to ensure a 'safe journey' for water, adding that the Leakage Detection Field would bring the country closer to achieving Sustainable Devel opment Goal (SDG 6).Mr. Maxwell Akosah-Kusi, Manager of Non-Revenue Water at GWL, demonstrated the use of the detection device, which collects leaking sound signals through its sensor, processed and displayed by the host machine with an output on its earphones. He explained that the water leakage point could be easily identified by listening to different and abnormal sounds categorized for repair by GWL engineers.
