Tanzania faces significant water challenges, including unpredictable rainfall, droughts and limited water management resources, putting pressure on agriculture, food security and development. With the added impacts of climate change and a growing population, effective water management is becoming more critical than ever.

In a World Bank-funded project, DHI developed an Operational Decision Support System (ODSS) to support informed decision-making, integrated water resources management and knowledge exchange across Tanzania.

Key components include a water resources information system and prediction tools for flood forecasting, reservoir operations decision-support, and water use permitting and allocation. In 2024, DHI developed and implemented the Water Use Permitting Analysis Tool, which aids decision-making when granting and evaluating water use permits.

With the ODSS, Tanzania is set to improve flood preparedness, enhance water allocation decisions and streamline reservoir management, ultimately minimising water shortages and optimising flood control strategies.
