  • Sanitary Safety Plans
  • Challenges in Drinking Water Regulations
  • Emergency and Incident Management
  • Innovations in Water and Sanitation Systems

The conference aims to foster dialogue and collaboration among stakeholders committed to delivering safe and sustainable drinking water.

Since the formation of the IWA Water Safety Planning Specialist Group (SG), one of our core missions has been to sustain and grow this important series of conferences. We are honored to be part of the organization and promotion of this global event.

We warmly welcome your participation and encourage you to join us in Ratmalana for vibrant discussions, networking, and knowledge exchange with professionals from around the world.

As the globally recognized best practice for ensuring the safety and reliability of drinking water supplies, Water Safety Plans (WSPs) play a vital role in protecting public health. In these uncertain times, sharing experiences and lessons learned is more crucial than ever. The 2026 IWA–WSCE will place special emphasis on recent advancements and innovations in water safety planning.

We look forward to your presence at this landmark event
