DELTA-SIERRA TOOL — MARS

Mars settlement water make-up calculator

How much fresh make-up water is required when the recovery loop is not perfect?

Essential answer

A 98% recovery rate means 2% of the flow inside the defined calculation boundary is not recovered. This tool converts that statement into daily and cumulative make-up demand.

Every value below can be changed. Prefilled values are educational examples, not an official NASA architecture.

Calculator

Q_makeup = Population × daily use × (1 − recovery efficiency)
Edit the values and run the calculation.

Method and limits

The calculator deliberately shows intermediate operations. Keep units visible, state the calculation boundary and distinguish a chosen assumption from measured performance.

A numerical result does not prove an architecture is feasible: availability, maintenance, contaminants, storage, redundancy and failure cases still require separate sizing.
