Water 2025
General Introduction
There is a finite amount of water on Earth. The increase in global demand for water not only creates a risk for your business but creates a risk for your community and planet on a broader scale. The operational, environmental, and financial impacts of water use are key issues for facility operations. Driving efficient water use and reductions throughout facility operations is an important area of focus for all factories.
In general, the Higg FEM Water section encourages you to:
- Identify and understand all water sources and uses at the facility.
- Understand what operations and processes at your facility use the most water.
- Track and report the quantity of water consumption at your facility.
- Evaluate, plan for, and adopt solutions to reduce water use through better manufacturing practices and water reuse/recycling.
- Implement leading practices to reduce water use at your facility.
- Contribute to sustainable water management and water stewardship activities in your community.
Additional details on the intent and criteria for each Higg FEM Water question is provided in the guidance below along with useful technical guidance and resources to support your facility in the management and reduction of water usage.
Water Use at Your Facility
In the Higg FEM, water use is categorized as either used for production or domestic purposes as defined below:
- Water used for Production: Water used in manufacturing processes or operations used to make goods (e.g., dyeing or rinse water, steam generation, water used in mixtures applied to the product, cleaning of equipment components or tools that contact the product during the manufacturing process, etc.)
- Water used for Domestic Purposes: Water used for washrooms, sanitation, drinking, food preparation, landscape irrigation, non-contact cooling etc.
The Higg FEM requires facilities to select the sources of water used at their facility. The FEM includes a list of predefined sources that can be selected. The table below provides a description of the available water source options in the FEM. These are categorized blue and grey water sources.
Blue Water Sources
Blue water is fresh surface and groundwater, in other words, the water in freshwater lakes, rivers and aquifers
| Water Source | Description |
| Surface Water | Water that is naturally occurring on the Earth’s surface (ice sheets, ice caps, glaciers, icebergs, ponds, lakes, rivers / streams, wetlands, bogs, etc.) Surface water has a low concentration of dissolved solids, is of an acceptable quality, and/or requires minimal treatment to be used for domestic, municipal, or agricultural applications. |
| Groundwater | Water in soil beneath the soil surface, usually under conditions where the pressure in the water is greater than the atmospheric pressure, and the soil voids are substantially filled with the water. Non-renewable groundwater is generally located at deeper depths and cannot be replenished easily or is replenished over very long periods of time. They are sometimes referred to as “fossil” groundwater sources. |
| Municipal Blue Water | Water provided by a municipality or other public provider that is generated by blue water. |
| Municipal Water (Origin Unknown) | Water provided by a municipality or other public provider with unknown origin (e.g., blue, or grey water) |
| Brackish surface water/seawater | Water in which the concentration of salts is relatively high (over 10,000 mg/l). For comparison, seawater has a typical concentration of salts above 35,000 mg/l. Brackish water is saltier than fresh water, but not as salty as seawater. It may result from mixing of seawater with freshwater, as in estuaries, but also certain human activities can produce brackish water. Brackish water is hostile to the growth of most terrestrial plant species. |
| Condensate from External Steam Source | Water that is generated from the condensate of steam sources that are not located at the facility. |
| Rainwater | Water in the form of precipitation (e.g., rain, snow) that is harvested within the facility either from the roof or other surfaces and stored for use. |
Grey Water Sources
Grey water is water that has been polluted by human activity (e.g., industrial, or domestic sources)
| Water Source | Description |
| Municipal Grey Water | Water provided by a municipality or other public provider that is generated by grey water. |
| Recycled Water | Wastewater that has been treated using physical, chemical, and/or any additional treatment processes to meet a quality which allows the water to be used again in a process or for domestic purposes. For example, wastewater that has gone through a membrane filtration process and used back in the industrial operation is considered recycled water. This does not include water cycled in operations such as cooling towers and non-contact heat exchange operations. |
| Reuse Water | Wastewater discharged from one process that is used directly in another process without treatment. This does not include water cycled in operations such as cooling towers and non-contact heat exchange operations. |
| Treated Wastewater from External Source | Wastewater that has been discharged and treated by an external source (e.g., other manufacturing facility) using physical, chemical, and/or any additional treatment processes to meet a quality which allows the water to be used again in a process. |
| Untreated Wastewater from External Sources (treated internally) | Wastewater that has been discharged by an external source (e.g., other manufacturing facility) and treated at your facility using physical, chemical, and/or any additional treatment processes to meet a quality which allows the water to be used again in a process. |
Water Data Quality
Accurately tracking and reporting water use data overtime provides facilities and stakeholders with detailed insight into opportunities for improvement. If data is not accurate, this limits the ability to understand a facility’s water use footprint and identify the specific actions that will help reduce environmental impacts and drive efficiencies. When establishing a water tracking and reporting program, the following principles should be applied:
- Completeness – The tracking and reporting program should include all relevant sources (as listed in the FEM). Sources should not be excluded from data tracking and reporting should be based on materiality (e.g., small quantity exceptions).
- Accuracy – Ensure that the data input into the water tracking program is accurate and is derived from credible sources (e.g., calibrated meters, established scientific measurement principles or engineering estimates, etc.)
- Consistency – Use consistent methodologies to track water data that allows for comparisons of water use over time. If there are any changes in the tracking methods, water sources, or other operations that impact water use data, this should be documented.
- Transparency – All data sources (e.g., water bills, meter readings, etc.), assumptions used (e.g., estimation techniques), and calculation methodologies should be disclosed in data inventories and be readily verifiable via documented records and supporting evidence.
- Data Quality Management – Quality assurance activities (internal or external data quality checks) should be defined and performed on water data as well as the processes used to collect and track data to ensure reported data is accurate.
Applicability Questions
To determine which questions you will need to complete in the Water section, you will need to complete the applicability questions listed below.
Based on the response to the applicability questions, facilities will be classified as a high or low water user, and a facility in an area of high or low water risk as follows:
- Facilities with low water use (defined as using less than 35m3 per operating day)
- Facilities with high water use (defined as using equal to or greater than 35m3 per operating day)
- Facility located in an area of low water risk (as defined by the WRI Aqueduct Tool or the WWF Water Risk Filter).
- Facility located in an area of high water risk (as defined by the WRI Aqueduct Tool or the WWF Water Risk Filter).
Facilities that are classified as either high water users or located in an area of high water risk (or both) will be asked to complete all FEM questions in the water section. Facilities classified as low water users that are located in areas of low water risk will only answer Level 1 questions.
1. How many days did your facility operate during this reporting year?
- List the number of days the facility operated in the reporting year.
- Note: Refer to the Site Information & Permits Section of the Higg FEM guidance on how to determine the number of operating days.
2. Select the tool used to assess your facility’s water risk.
- WWF
- WRI
Facilities will be asked to evaluate their water risk using both the WRI Aqueduct Tool and the WWF Water Risk Filter.
Notes:
- Facilities must report their water risk based on the highest water risk ratings from the two tools (e.g., if the WRI tool shows low risk and the WWF tool shows high risk, the high risk must be reported).
- Facilities should capture screenshots and/or downloads of the risk assessment outcome and upload as evidence to show that the risk assessment was done within the FEM reporting year.
The WRI Aqueduct Tool and the WWF Water Risk Filter are simple and similar tools to assess water scarcity risks.
When using the WRI Aqueduct Tool go to the home page and select explore global water risk maps and select Enter Address at the bottom of the screen to search using your facility address. Facility should select the default Overall Water Risk weighing scheme.
When using WWF Water Risk Filter, click on the maps feature under the Water Risk menu option and search for your country and location. Look at the color-coding of the map to determine the Basin Physical risk for the area your facility is located . This link provides information on the data and methodology and scoring matrix used in the Risk Filter.
Note: “Low risk”, “Low to medium risk” and “Medium to high risk” are defined as “Low risk” in FEM. “High risk” and “Extremely/Very high risk” are defined as “High risk” in FEM.
3. Is your facility location rated as high/very high for overall water risk using this tool?
- Yes
- No
4. Is your facility using water for production use?
- Yes
- No
5. Is your facility able to separately report water consumption by each facility type?
- Yes
- No
Answer Yes If: Your facility tracks water consumption separately for the different facility types selected in the Site Info Section of the FEM.
Note: This applicability question will only apply to facilities that have selected “Finished Product Assembler” AND “Finished Product Processing” as the only two facility types in the Site Info Section of the FEM.
