Water Autonomy Calculator

Estimate daily water consumption and determine how long your stored water can support the people living in an Oasis.

This provides a planning baseline that can later be compared with actual water-meter and tank measurements.

INPUTS

Describe the water system.

litres
Enter the total usable water stored across tanks, cisterns or reservoirs.
people
Number of people supported by the stored water.
L/day
Include the uses you want this storage system to support: drinking, cooking, washing, sanitation or other selected loads.
Formula: Stored Water ÷ ( People × Litres per Person per Day ) = Days of Autonomy
WATER RESILIENCE Autonomy Forecast
ESTIMATED
Daily Use — litres / day
Autonomy — days
Equivalent — weeks
Water Metric Value Unit Status
Stored Water Available usable volume

INPUT supplied
Daily Consumption Total for all people
— L/day
— L/30 days
— L/year
Storage Autonomy At the selected consumption rate

Data status: ESTIMATED

Compare later with measured household consumption.

CONTROL ROOM

Send water data to the Control Room

This calculator can update two estimated Control Room values:

water.consumedLitres — estimated daily consumption

storage.waterStoredLitres — current stored water

WATER INTELLIGENCE

Storage means little without knowing consumption.

A resilient water system connects collection, filtration, storage, consumption and reuse into one measurable loop.

01

Collect

Measure incoming water from rainfall, wells and other sources.

02

Store

Track how much usable water is available at any moment.

03

Consume

Understand daily demand instead of relying only on tank size.

04

Recover

Reuse suitable greywater and recovered water to reduce demand.
