Utility operators

How much time do essential reserves buy at reference demand?

The reference reserve covers 7d at essential demand. Actual usable stock and replenishment must be verified.

Citywide reference · not an observed reading or a local allocation

Evidence needed before a decision

Water quality, actual stock, firm supply and accepted demand readings are needed to verify resilience.

Resource planners

What supply remains necessary after the recovery assumption?

The recovery assumption still leaves 23.8 ML/day to replace. Reuse does not remove the need for an external supply.

Emergency planners

Which demand must be protected when supply is interrupted?

Essential water demand: 30 ML/day in the source reference. Water quality, actual stock, firm supply and accepted demand readings are needed to verify resilience.

Read the evidence with the insight

These are the existing citywide reference calculations. They are not observed outcomes or allocations to a district, neighbourhood or facility. The interactive dashboard exposes each measure’s source, units and calculation. Scenario changes remain modelled outputs.
