How to Use This Calculator
  1. Enter the total personnel count at the field site.
  2. Set the operation duration (days) for cumulative supply calculations.
  3. Select climate zone: 0=Cold, 1=Temperate, 2=Hot/Arid — hot climates require more water and more frequent waste disposal.
  4. Review Latrine units (1 per 8 personnel), Handwash stations, and Soakage pits needed for the site.
  5. Use JP-8 for latrines (gal) and Disinfectant (gal) to pre-stage sanitation supplies.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Personnel = 200, Duration (days) = 30, Climate (0=cold, 1=temp, 2=hot) = 1 = 3 input(s) provided
  2. Calculate Latrine units
    Latrine units = ceil(latrineSeats / 4)
    7 = 7
  3. Calculate Handwash stations
    Handwash stations = ceil(latrineUnits / 2)
    4 = 4
  4. Calculate Soakage pits
    Soakage pits = ceil(grayWaterGalPerDay / 200)
    5 = 5
