Water Demand Calculator: calculate daily demand (l) using defined numerical inputs.
Formula
- Model: population × demand per person per day. Illustrative user-input planning arithmetic, not a regulatory design standard. Inputs must be nonnegative. This tool performs the stated calculation on user-provided inputs; it is not an official certification.
- The main inputs are Population, Demand per person per day. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Water Demand
- Population: 100
- Demand per person per day: 150 L
Using Population = 100, Demand per person per day (L) = 150, the calculated result is Daily demand (L): 15000.
