How to Calculate Your Water Footprint


How to Calculate Your Water Footprint

You should have in mind that water footprint includes the extent of water that we use in comparison to people's consumption of it.

Have in mind that water footprint of community, individual or business is a remarkable fact that will help you determine the overall volume of freshwater consumption that we use to produce services and products that are consumed by the society.

When it comes to measurements, have in mind that it measures in volume consumed per unit of time, and you will be able to calculate it for the precise group of consumers, such as province, state, village, nation or family, or producers that include private enterprises, public organizations, and industries that are affecting economic sector.

According to the historical perspective, you should have in mind that water use is vital for the production of everything that surrounds us. Therefore, you will be able to differentiate three perspectives of water usage: industrial, agricultural, and domestic.

By calculating the valuable data, you will have a complete approach to water usage in the world that surrounds us.

Have in mind that some industries are not based on the water from the country in which they operate, which also creates social havoc and perspective in which we have to preserve limited amounts of this essential resource.

You will be able to calculate water footprint with an idea to understand the consumption based on the overall usage, and this particular information will help you create both understanding and comprehensive plan that will reduce the intake and preserve it in the long run.

It is essential since water footprint depends on geographical location and indicator, which means that it will show you both volumes of water pollution and consumption as well as areas so that you can do something about it.

Finally, it will help you create an understanding of how the economy uses the available water resources so that you can determine the exact reality we live in nowadays.

Do We Have Enough Water?

According to worldwide consumption, four percent of the water has been used by agriculture, and have in mind that almost half of it can evaporate in forests and other natural landscapes.

When it comes to groundwater, you should have in mind that actual renewable freshwater resources are highly valuable, and it represents the water that you can use after withdrawing it from surface or groundwater.

Therefore, 69% of water goes for agriculture, while 19% goes for other industries. The main reason why we need water for agriculture is through irrigation processes, which uses 5.1% of entire renewable water resources.

Different Types of Water Footprints

Blue Water Footprint

When it comes to blue water footprint, you should remember that it represents the volume of water that we use from groundwater resources and surfaces such as aquifers, wetlands, rivers, and lakes and has been incorporated into the product or has evaporated through irrigating crops. As a result, water has returned and changed its shape into an entirely different perspective. Therefore, the main aspects of blue water footprint are understanding domestic, industry, and agricultural water usage.

Green Water Footprint

This particular footprint includes the amount of water from the moment of precipitation in the root zone of the soil that has been incorporated by plants or lost through evapotranspiration. It is highly important to measure it because it is relevant for forestry, horticultural, and agricultural products.

Grey Water Footprint

We are talking about the volume of water that we need to dilute numerous pollutants that are happening around us from seepage from making ponds at mining operations, industrial discharges, nonpoint source pollutions, and untreated municipal wastewater. It calculates everything to the extent that we have to use quality water, which is meeting standards.

How to Calculate Water Footprint?

We are expressing this particular process as the volumetric flow rate of water, which includes the entire sum of the methods as well as a complete supply chain that we have to divide by the number of product units created afterward.

On the other hand, for a geographical area, businesses, and consumers, water footprint is an essential indication of the volume of water-based on time:

You should calculate the sum of water footprint based on consumer products that we all use daily.

You can summarize the entire consumption based on the nation or community by checking out the inhabitants and their responsibilities.

You can measure water footprint based on the overall life cycle of produced goods and used water so that you can handle everything.

You can geographically limit one area so that you can create a footprint measurement that will help you create alternative ways of preserving. You can create a virtual balance of a city and define the purpose of the water-based on consumer needs.

Life Cycle Assessment of Water Usage

When it comes to life cycle assessment, you should have in mind that includes phased and systematic approach that will assess all the potential impacts and aspects that are wholly associated with a specific service, process or product.

Therefore, this particular method will help you determine the environmental impacts of freshwater consumption, and it includes explicitly three areas of protection: resources, ecosystem quality, and human health.

Therefore, the amount of water consumption is highly significant especially in areas where water is scarce or if the agricultural industry is taking too much of it.

Generally, life cycle assessment is vital because it will help you identify the water use in individual companies, consumers, products, nations, and many more.

The water footprint of a business, for instance, includes the overall volume of freshwater that they have used both indirectly and directly to support and run a business.

 It depends on outputs as well as inputs, and it depends on the amount used for manufacturing and dealing with supporting activities that will help you pass the supply chain.

On the other hand, individual water footprint depends on the amount of indirect and direct water use at household. Direct includes the usage inside the home, while indirect relates to the overall amount of fresh water that we need to produce services and products we regularly consume.
