Hello!
Corporate Water
Footprint Services
Water Footprint Validation and Certifications
Fresh water is the most precious resource on Earth. Despite covering more than 70% of our planet's surface, less than 3% of that water is fresh — and most of that is locked in glaciers and ice caps. The availability of accessible, clean freshwater is under increasing pressure from population growth, climate change, and industrial demand.
Rexizon Global Solutions offers comprehensive Corporate Water Footprint services: measurement, validation, and certification of your organisation's water consumption across the full product and process lifecycle. We help companies understand the true extent of their water impact and develop credible reduction strategies.
Our methodology follows internationally recognised standards, enabling your organisation to benchmark performance, set science-based targets, and communicate water stewardship to investors, regulators, and customers with confidence.
Understanding
Water Scarcity
Population Growth
The global population is projected to reach nearly 10 billion by 2050. Agricultural, municipal, and industrial water demand will rise in tandem, placing severe strain on already limited freshwater reserves. By 2025, two-thirds of the world's population may face water shortages.
Climate Change
Rising temperatures are disrupting precipitation patterns, accelerating glacial melt, and intensifying droughts. Many regions that rely on seasonal snowpack or rainfall for freshwater supply now face unpredictable hydrological cycles, reducing the reliability and volume of water available for human use and ecosystems.
Pollution
Industrial discharge, agricultural runoff, and inadequate wastewater treatment degrade water quality on a vast scale. Contaminated water bodies cannot be used for drinking, irrigation, or manufacturing without costly treatment, effectively removing enormous volumes from the usable freshwater supply.
What is a
Water Footprint?
The concept of the Water Footprint was introduced by Prof. Arjen Hoekstra at UNESCO-IHE in 2002. It is an indicator of freshwater use that looks not just at direct water use by a consumer or producer, but also at the indirect water use across the entire supply chain.
A Water Footprint is expressed in volume of water consumed and/or polluted per unit of product or time. It is composed of three distinct components:
Green Water
Rainwater stored in the soil as moisture. It is the water evaporated, transpired, or incorporated into the product during the production process. Particularly relevant for agricultural and forestry products.
Blue Water
Surface water and groundwater — rivers, lakes, and aquifers — consumed during production. This is the water that is drawn from the natural environment and not returned to the same catchment in the same period.
Grey Water
The volume of freshwater required to assimilate pollutants to meet ambient water quality standards. It reflects the degree of freshwater pollution associated with a production process or product.
Why Water Footprint
Matters
Water is the hidden ingredient in virtually every product we make, buy, and consume. The vast majority of a product's water impact occurs far upstream in the supply chain — in agriculture, raw material extraction, and manufacturing — and is entirely invisible to end users and even to many businesses.
Invisible Consumption
It takes approximately 15,000 litres of water to produce 1 kg of beef, 1,500 litres for 1 kg of wheat, and 140 litres for a single cup of coffee. Understanding these embedded water flows is essential for organisations that want to manage their resource impact responsibly.
By measuring and certifying your Water Footprint with Rexizon, you gain the evidence base needed to make meaningful reductions — and to communicate those reductions credibly to the world.
The Aqua Blue Certification is awarded to organisations that achieve measurable, independently verified reductions in water consumption — demonstrating genuine commitment to water stewardship.
Why a Water
Footprint Label?
Who We Serve
Organizations 01
To measure, reduce, and communicate the water footprint of their products, sites, and services — and to embed water efficiency into operational and strategic planning across the full lifecycle.
In-Process & Circular Water Management 02
Manufacturers and processors seeking to integrate water recirculation, closed-loop treatment, and zero-liquid-discharge approaches into their production lines — reducing freshwater intake and wastewater discharge simultaneously.
Product Differentiation 03
Brands that want to distinguish their products with a credible, independently verified water label — signalling responsible sourcing and production to retailers, procurement teams, and end consumers who increasingly prioritise sustainability credentials.
Customers 04
Corporate buyers and procurement departments that want to assess and reduce the embedded water footprint of their supply chains, and to make informed sourcing decisions that align with their own water stewardship commitments.
Individuals 05
Consumers and professionals who want to understand the water impact of their personal choices — from diet and clothing to everyday household consumption — and to make meaningful lifestyle adjustments that support global water security.
Rexizon Water
Footprint Services
Rexizon Global Solutions provides end-to-end Water Footprint services tailored to your organisation's sector, scale, and ambition. Our multidisciplinary team combines hydrological expertise, lifecycle assessment methodology, and ESG reporting knowledge to deliver actionable results.
Our Methodology
We follow the Water Footprint Assessment methodology established by the Water Footprint Network (WFN), grounded in the original framework developed at UNESCO-IHE in 2002. Our approach is fully compatible with ISO 14046 (Water Footprint — Principles, Requirements and Guidelines) and integrates with leading ESG disclosure frameworks.
Every assessment is conducted by certified specialists and subject to independent verification before certification is awarded — ensuring that your Water Footprint Label carries genuine credibility.
Towards Sustainable
Water Management
Water is not an infinite resource. The decisions organisations make today about how they source, use, and discharge water will determine whether future generations have access to the clean freshwater they need to thrive. Sustainable water management is no longer simply a matter of regulatory compliance — it is a business imperative, a social responsibility, and an investment in long-term operational resilience.
At Rexizon Global Solutions, we believe that measurement is the first step towards genuine improvement. By quantifying your Water Footprint with scientific rigour, we provide the foundation you need to set credible targets, drive real efficiency gains, and communicate your commitment to water stewardship with confidence.
Together, we can build organisations that use water wisely, protect the watersheds on which communities depend, and contribute to a world where clean water remains accessible for all.
