Non-Revenue Water Management Training Workshop: WaterLinks Shares Asia’s Experience
On the occasion of the 6th GWOPA Congress in Bonn, Germany on 27 October 2025, WaterLinks participated in a Training Workshop on Non-Revenue Water (NRW) Strategies for Urban Water Service Providers Across Europe, Asia, and Africa. The workshop gathered utilities, water professionals, and development partners to exchange experiences and practical solutions for reducing NRW, a critical issue affecting the efficiency and sustainability of urban water systems worldwide.
Mai Flor presented case studies from Asia, that showed how utilities in the region are implementing effective technical and economic approaches to reduce and manage NRW. Her presentation highlighted the value of peer-to-peer learning and collaboration through WOPs in strengthening utility performance and promoting sustainable practices. The Asian case studies featured:
- WOP between Khulna Water Supply and Sewerage Authority, Bangladesh and PDAM Surya Sembada Kota Surabaya, Indonesia
- WOP between Danang Water Supply Joint Stock Company, Vietnam and Manila Water Company Inc., Philippines
The workshop featured regional case studies from Europe, Asia, and Africa, with each utility sharing its strategies, success factors, and challenges in tackling NRW. Participants then engaged in small group discussions, reflecting on their utilities’ current NRW management practices, challenges, and the potential applicability of the strategies presented. The session also featured the following case studies:
- SMAT, Italy – Non-Revenue Water Strategies for Urban Areas: Technical and Economic Elements
- Ethiopia – NRW Reduction Strategy in Gambella, Assosa, and Semera–Logia
