Team and workplace logistics
Team hydration supply calculator
Plan water, bottles or coolers, reserve, and break-by-break staging for a crew, team, class, tournament, or outdoor event.
Quick answer
Multiply a clearly chosen per-person planning allowance by group size and active time, then add reserve and convert the total into containers. Treat the result as supply logistics, not a forced drinking target, and pair it with cooling, rest, access, acclimatization, and emergency procedures.
Supply plan
About 9.5 US gallons, including 6 L of reserve. This is aggregate supply to stage, not an instruction that every person must drink the full allowance.
- Containers
- 72
- bottles at 500 ml
- Cases
- 3
- 24 containers each
- Distribution points
- 6
- about every 20 minutes
- Stage per break
- 5 L
- aggregate across the group
Print checklist
- Stage 36 L total (72 containers / 3 cases).
- Keep water accessible and plan roughly 6 distribution or check-in points.
- Pair the plan with rest, shade or cooling, acclimatization, workload changes, and an emergency response process.
- Do not wait for severe symptoms or treat confusion, fainting, seizures, or worsening heat illness with hydration math alone.
Planning boundary
CDC/NIOSH provides workplace examples for moderate work in heat, but real needs vary. Never force drinking, exceed clinician restrictions, or use this result as proof that a worksite or event is safe.
Supply by period or location
Split a chosen allowance across delivery points. Each row is a separate allocation; people appearing in two periods are counted in each period. Delivery times are minutes from event start. Confirm storage, access and responsibility locally.

Point / period 1
Procurement and handoff
3 pooled cases · 72 containers to stage
Base 30.00 L + reserve 6.00 L. Purchase 36.00 L in whole cases. Separate deliveries require 3 cases if cases cannot be split.
- Point 1 · minute 0: stage 72 containers (36.00 L including reserve) · 3 separate cases
These are supply logistics for the allowances you chose. They do not set a personal drinking dose, heat-safety compliance or a safe maximum. Clinical restrictions override the plan.

Team supply handoff
Your chosen plan - amounts are not a prescription
Container: 0.50 L
Reserve: 6.00 L (20%)
Pooled cases to buy: 3 × 24
Purchased volume: 36.00 L
| Time / point | People / hours | Amount | Containers to stage | Notes / check |
|---|---|---|---|---|
| 1 / 0 min | 20 / 2 h | 36.00 L | 72 |
Each point is rounded up to whole containers. Cases are pooled across points; separate deliveries may need more cases. Confirm access, timing and storage locally. Handoff: responsible person __________; checked at __________; next delivery __________.
Adult planning tool. Clinical fluid limits and clinician instructions override this sheet. Do not force drinking to complete a target.
Daily estimates use site assumptions, not a measured need. Team and race amounts are chosen by you; no medical dose or sodium requirement is calculated.

Worked supply example: a 20-person crew
Choose 750 ml per person per hour for a two-hour logistics example: 20 × 2 × 0.75 = 30 L. A chosen 20% reserve adds 6 L, so stage 36 L: two 19 L containers provide 38 L of capacity. These inputs are editable purchasing assumptions, not a dose each worker must finish.
At six 20-minute access checks, the base supply averages 5 L per check for the group; the 6 L reserve remains separate. Confirm refill access, cup availability, shade, cooling, workload and emergency arrangements with the responsible supervisor.
Official heat-safety context
The calculator handles procurement math only. Use official guidance to design the wider heat plan and local emergency process.
Frequently asked
Is this a required drinking amount for every person?
No. The result is an aggregate supply-planning allowance, not a prescription or a requirement that each person drink the full amount. Individual needs, clinician restrictions, work intensity, heat, clothing, and access vary.
Which planning allowance should I use?
Choose a transparent scenario and keep reserve available. CDC/NIOSH gives workplace examples for moderate work in heat, but the calculator deliberately lets the planner choose instead of silently presenting one universal formula.
Does enough water make hot work safe?
No. Heat plans also need rest, shade or cooling, acclimatization, workload controls, symptom monitoring, and emergency response. Severe or worsening symptoms require cooling and escalation, not only more fluids.
