How to Use This Calculator
  1. Enter the species and number of animals requiring water.
  2. Set the season and ambient temperature to apply the correct consumption multiplier.
  3. Review the daily water requirement in gallons for the entire herd or flock.
  4. Size waterers and storage tanks to provide at least 1.5× the daily requirement.
  5. Inspect water system capacity during peak summer demand when intake increases 50-100%.

What each input means

Head Count
Total number of animals in the herd or flock.
Average Weight
Average live weight per animal in pounds.
Species
1 = Cattle, 2 = Horse, 3 = Sheep, 4 = Goat, 5 = Hog.
Ambient Temperature
Average daytime temperature in degrees Fahrenheit. Water needs increase in heat.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Head Count = 50, Average Weight = 1000, Species = 1, Ambient Temperature = 75 = 4 input(s) provided
  2. Calculate Gallons per Head/Day
    Gallons per Head/Day
    12 = 12
  3. Calculate Daily Total
    Daily Total
    600 = 600
  4. Calculate Weekly Total
    Weekly Total
    4200 = 4200
