← Use Cases Forecast
What is this?
Assess whether current water sources will meet future demand given population growth, climate change, and infrastructure ageing — and identify what new investment is needed.
When does it happen?
Strategic planning cycle, typically every 5–25 years. Triggered by drought events, population projections, or policy changes.
What data is used?
Population and demand forecasts, climate projections, infrastructure condition assessments, cost models.
What decision is made?
“Is supply sufficient for the next 25–50 years? If not, what combination of new sources, efficiency, and demand management is optimal?”
What action follows?
Develop a water resources management plan; secure funding; commission new infrastructure or programmes.

Proven strategies for handling this scenario:
National water strategies
Water challenges cross boundaries between cities, regions, and agencies. Without a national plan, investments are uncoordinated and gaps emerge.
