What is Water Quantity Estimation?

Water Quantity Estimation is the process of calculating the total amount of water required to meet the needs of a population. It is based on the per capita demand (water consumption rate per person) and the total population to be served.

The calculator helps users estimate the total municipal water demand based on population size and per capita water consumption

Why is Water Quantity Estimation Important?

Estimating water quantity is essential for:

• Urban Planning: Designing water supply systems for cities and communities.
• Resource Management: Ensuring adequate water supply for daily needs.
• Emergency Preparedness: Planning for water requirements during emergencies or disasters.

How to Use the Calculator

The quantity of water required for municipal uses for which the water supply scheme has to be designed requires following data:

1. Enter Water consumption rate (Per Capita Demand in litres per day per head) : Input the water consumption rate per person in liters/day.
2. Enter Population: Input the total number of people to be served.
3. Calculate: Click "Calculate Water Quantity" to see the total water required.

Water Consumption Rate

It is very difficult to precisely assess the quantity of water demanded by the public, since there are many variable factors affecting water consumption. The various types of water demands, which a city may have, may be broken into following classes:
