Scenarios
- How your work is kept: (1) Toolbar Restore Autosave — one browser recovery slot for the current worksheet (not a named scenario row). (2) Save / Load Scenario — named snapshots in the dropdown. (3) Export / Import — files on disk; export does not add a scenario until you Import JSON or Save.
- The toolbar Autosaved: line shows when the recovery slot was last updated (format Autosaved: M/D h:mm AM/PM).
- Save Scenario stores your current inputs, unit, and modes in this browser.
- Use a clear scenario name and notes so others can quickly understand assumptions.
- Load restores a saved setup, Delete removes one scenario, and Clear all removes all saved scenarios.
- Export downloads JSON (backup/re-import) or CSV (report); Import applies a JSON file — it is separate from the toolbar recovery slot.
- The line under scenario name is for the named scenario list only — different from worksheet autosave.
Deployment Parameters
- Length of operation and bed count drive total water demand.
- Typical: 30–90 days, 10–50 beds.
- Buffer adds a safety margin (e.g. 10% = 10 extra percent on all quantities).
Add percentage buffer to water quantities (e.g. 10 for 10%)
Water Use (per bed per day)
- Rates are per bed per day in the unit you select (L or Gal).
- Typical potable: 22–27 Gal (80–100 L)/bed/day.
- Typical wastewater: ~18 Gal (~65 L)/bed/day (gray + black).
Estimate potable demand and wastewater output per bed per day using field-planning references (MSF/WHO/Sphere).
Storage Configuration
- Number of containers and capacity per container (in L or Gal, same as above).
- Used to estimate how often water deliveries and waste pickups are needed.

Supply & Disposal Mode
- Self-supplied: Water delivered to on-site storage; wastewater collected and removed.
- Mains water: Connected to municipal or base water supply.
- Mains sewer: Connected to municipal or base sewage. No wastewater pickups required.
Estimated Totals & Schedule
- Totals use your deployment days, beds, rates, and buffer.
- Delivery and pickup intervals are based on container capacity and daily demand.
