Every summer, the same question lands on a safety or operations manager's desk: how much hydration do we actually need? Most teams answer it one reorder at a time, and that is how crews end up with a stockroom that's overflowing in May and empty by July.
There's a better way. Planning a full season of crew hydration comes down to four numbers: crew size, how much each worker drinks per shift, how many working days your hot season runs, and how much of that should be an electrolyte drink versus plain water.
Here is how to work through each one, a worked example for a 10-person crew, and how to turn the result into a supply plan you can set once and stop thinking about.
The most widely used workplace benchmark comes from NIOSH: about one cup (8 oz) of fluid every 15 to 20 minutes for moderate work in warm conditions, and no more than 48 oz per hour. Over an eight-hour shift, that works out to roughly 1.5 to 2 gallons per worker per day.
That total covers all fluids, not just sports drinks. Most crews split it between water and an electrolyte drink, especially on long shifts and physical work, where workers lose electrolytes along with fluid. Decide your split up front. Many teams plan for about half of daily intake as an electrolyte drink and the rest as water.
Once you know the daily number per worker, the season is simple multiplication. Here is the formula:
Worked example for a 10-person crew:
Swap in your own crew size and season length, and the same three steps give you your number.
The right format depends on where and how your team drinks during the day. Most crews end up with a mix:
If you would rather start from a ready-made mix, hydration program bundles package the most common combinations for crews in one order.
A season plan turns hydration from a recurring scramble into one decision. You know what you need, how it's packed, and when it shows up, and every brand your crew drinks can ride on a single order.
