The Public Utilities Regulatory Commission (PURC) has raised concerns over escalating levels of non-revenue water (NRW) within Ghana's urban water sector, with the Western Region, Accra West, and Tema identified as the areas of most significant concern. According to the Commission's report for the first quarter of 2026, the Western Region recorded a staggering 66.1% loss, followed by Accra West at 57.2% and Tema at 56.8%. These figures contributed to an overall national non-revenue water level of 49.2% for Ghana Water Limited (GWL), significantly exceeding the regulatory benchmark of 43%.
The report highlights a systemic challenge for Ghana Water Limited, as only three out of its 13 operational regions managed to meet the 43% benchmark during the period under review. While the Western Region faces the most critical situation, other regions including Ashanti North, Upper East, and Volta recorded levels closer to the threshold, suggesting that targeted corrective measures could bring them into compliance relatively quickly. The PURC has emphasized that the high levels of water produced but not billed—due to physical leakages, commercial losses, or metering inaccuracies—pose a threat to the financial and operational sustainability of the national utility provider.
Despite the high loss percentages, there were positive indicators regarding production and revenue collection efficiency. National water production saw a marginal increase of 1% in Q1 2026, while water sales grew by 3.7% in the same period. This discrepancy suggests an improvement in the conversion of produced water into billed sales, particularly within the Accra-Tema Metropolitan Area, which remains the country's largest and most critical water-producing system. However, the Commission noted that these efficiency gains are currently being offset by the sheer volume of physical and commercial losses in high-pressure urban zones.
To address these inefficiencies, the PURC has recommended the immediate implementation of comprehensive loss-reduction programs. These interventions include intensified leakage detection exercises, the replacement of faulty meters, and improved billing management systems. For the Western Region specifically, the Commission is calling for a prioritized intervention strategy to stabilize the network. As the regulator, PURC maintains that reducing non-revenue water is imperative for enhancing the overall performance of GWL and ensuring that the utility can reinvest in infrastructure to meet the growing demand for clean water across Ghana.
