What is this?
Implement restrictions, campaigns, and pricing measures to cut water consumption when supply is running low.
When does it happen?
When reservoir levels or aquifer levels fall below trigger thresholds, typically during drought. Escalating stages of restriction may apply.
What data is used?
Reservoir levels, per-capita consumption data, weather forecasts, leak rates, compliance monitoring.
What decision is made?
“What level of restriction is needed? Voluntary or mandatory? For how long?”
What action follows?
Impose hosepipe bans or usage limits; launch public awareness campaigns; increase tariffs; deploy enforcement; accelerate leak repairs.

Demand reduction programmes
Building new supply infrastructure is expensive and slow. In many cases, reducing how much water people use is faster, cheaper, and more sustainable.
