Water Risk in ESG: Why It Matters for Industries
Introduction
Businesses have focused on reducing their carbon footprint, improving energy efficiency and setting net-zero targets.
However, Water Risk in ESG is emerging as another critical priority for businesses worldwide. From manufacturing plants and power stations to chemical industries and commercial facilities, businesses depend on reliable water supplies to keep their operations running. Water scarcity, rising consumption, pollution and stricter environmental expectations are making responsible water management an essential part of long-term business sustainability.
Why Is Water Becoming a Major ESG Concern?
Water is essential to almost every industrial process. It is used for cooling, cleaning, manufacturing, processing, heating and equipment operation.
However, freshwater availability is not unlimited. Growing industrial demand, urbanisation, changing rainfall patterns and groundwater depletion are increasing pressure on water resources.
For industries operating in water-stressed regions, unreliable water availability can lead to production interruptions, higher operating costs and supply chain challenges.
According to CDP, water security is a significant financial risk for businesses. Its corporate disclosure framework encourages companies to measure water-related impacts, assess exposure and report their progress towards better water management.
This makes water management an important part of long-term business resilience.
How Does Water Risk Compare with Carbon Risk in ESG?
Carbon risk and water risk are different, but both can influence business performance and environmental sustainability.
Carbon risk is generally associated with greenhouse gas emissions, climate regulations, energy transitions and changing environmental expectations.
Water risk involves the availability, quality and accessibility of water required for business operations.
Consider these examples:
Carbon Risk
- Greenhouse gas emissions from industrial operations.
- High energy consumption.
- Dependence on fossil fuels.
- Climate-related regulatory requirements.
Water Risk
- Water scarcity and groundwater depletion.
- High freshwater consumption.
- Industrial wastewater discharge.
- Water pollution and treatment challenges.
- Dependence on water-stressed locations.
The two risks are also connected. Climate change can influence rainfall patterns, drought frequency and water availability, making water management an important part of climate resilience.
Which Industries Face the Highest Water-Related Risks?
Water-intensive industries are particularly exposed to water-related challenges because their operations depend on consistent water availability and quality.
Some important examples include:
1. Power Generation
Power plants use significant quantities of water for cooling and other operational processes. Water shortages can affect cooling capacity and operational continuity.
2. Textile and Manufacturing
Textile manufacturing uses water for dyeing, washing and processing. Without effective treatment and recycling, these activities can contribute to high freshwater consumption and wastewater generation.
3. Chemical and Pharmaceutical Industries
These industries require water for manufacturing, cleaning, cooling and other processes. Maintaining water quality and managing wastewater are essential operational requirements.
4. Food and Beverage Processing
Water is used for washing raw materials, processing, cleaning and sanitation. Efficient water management is important for maintaining production standards and reducing resource consumption.
5. Steel and Heavy Industries
Steel production and other heavy industrial processes depend on water for cooling and equipment operations. Managing scale formation, cooling systems and water reuse can support operational efficiency.
What Should Industries Include in Their Water Sustainability Strategy?
Managing water risk requires more than reducing consumption. Businesses need to understand where water comes from, how it is used and where it goes after use.
Here are five important areas industries should focus on.
- Conduct Regular Water Audits
Measure water withdrawal, consumption and discharge across different operations. Identifying high-consumption areas helps businesses recognise opportunities to improve efficiency.
- Invest in Water Recycling and Reuse
Treated wastewater can be reused for suitable applications such as cooling, cleaning and landscaping, depending on its quality and applicable requirements. This can reduce dependence on freshwater sources.
- Improve Cooling Tower Efficiency
Cooling towers are important in many industrial facilities. Regular monitoring, blowdown management and effective scale prevention can support efficient cooling system operation.
- Prevent Scale Formation in Industrial Equipment
Mineral scale can accumulate in boilers, cooling towers, heat exchangers and pipelines. Managing scale formation helps maintain heat transfer performance and reduces scale-related maintenance requirements.
- Monitor Wastewater Quality
Industries should implement suitable wastewater treatment processes and monitor discharge quality to meet applicable environmental requirements.
Why Is Water Disclosure Becoming Important in ESG Reporting?
Corporate sustainability reporting is gradually placing greater attention on water-related impacts, dependencies and risks.
For example, the European Sustainability Reporting Standards include ESRS E3, which addresses water and marine resources. It covers water-related policies, actions, targets and water metrics where the topic is material.
Similarly, IFRS S1 requires companies to disclose material sustainability-related risks and opportunities that could affect their business prospects. Water dependencies can fall within this broader assessment.
These developments demonstrate why companies should integrate water management into their sustainability strategies rather than treating it as a separate operational concern.
How Can Better Water Management Support a Sustainable Industrial Future?
Sustainable water management is not only about using less water. It is about using water more responsibly throughout the operational lifecycle.
Industries can take practical steps such as:
- Implementing water-efficient equipment and processes.
- Improving wastewater treatment and recycling.
- Monitoring water consumption through regular audits.
- Optimising cooling towers and boiler operations.
- Preventing unnecessary water losses.
- Adopting suitable water treatment and scale prevention technologies.
Solutions that improve water efficiency and help manage scale formation can contribute to better industrial water management.
At SOFTFLOW®, our focus is on helping residential, commercial and industrial facilities manage hard water scale through salt-free scale prevention technology. Addressing scale-related challenges is one part of a broader approach to responsible water management.
Conclusion: Water Deserves a Place Alongside Carbon in ESG
Carbon reduction remains essential, but businesses cannot overlook the growing importance of water security.
Water scarcity, industrial consumption, wastewater management and water-related operational risks are becoming important considerations for companies working towards long-term sustainability.
The next step for industries is to move beyond simply reporting environmental commitments and start implementing measurable water management practices.
Because a sustainable industrial future depends not only on reducing carbon emissions but also on protecting the water resources that keep businesses running.
Effective water treatment also plays an important role in reducing environmental impact. Read more about how water treatment impacts your carbon footprint
Frequently Asked Questions (FAQs)
How do you remove hard water spots quickly?
Fresh hard water spots can often be removed using a suitable surface cleaner. A diluted vinegar solution may help on compatible glass and fixtures. Always rinse thoroughly and check the manufacturer’s cleaning instructions.
What is the best way to remove hard water spots from glass?
For compatible glass surfaces, a diluted white vinegar solution can help loosen mineral deposits. Wipe with a microfiber cloth, rinse thoroughly and dry the surface.
Why do hard water spots keep coming back?
Hard water spots return because the water continues to contain dissolved minerals. When water evaporates, these minerals can remain on the surface and form new deposits.
Can a water softener prevent hard water stains?
Conventional water softeners reduce hardness by removing calcium and magnesium ions. Salt-free scale prevention systems help manage scale formation without necessarily removing these minerals.
