FEM 2023 Water and Waste Calculations
Water Data
Data about production and domestic water use is collected in the Water section of FEM separated by facility type.
Domestic water use is either reported as a part of production use, in the case that a facility cannot separate the water usage, or separately.
You can determine whether a facility is reporting water values split between domestic and production or combined by looking at the ref_id wattrackdomprodsep an answer of No means the facility is reporting combined (row 3 in the table below) and Yes means separated (rows 1 and 2 in the table below). Because a facility will never report using both methods they may safely be summed without risk of double counting.
Raw water use is reported in the follow ref_ids:
| Scope | Usage | Unit of Measure |
|---|---|---|
| Domestic | wattrackdom[1]quant | wattrackdom[1]unit |
| Production | wattrack[1]prod[2]quant | wattrack[1]prod[2]unit |
| Domestic & Production | wattrack[1]all[2]quant | wattrack[1]all[2]unit |
Where the wildcards [1] and [2] represent the water source and facility type which may be any of the following values:
| Index | Kind | Reference | Value |
|---|---|---|---|
| 1 | Water Source | watsourcesurface | Surface Water |
| 1 | Water Source | watsourceground | Groundwater |
| 1 | Water Source | watsourcemunicipalblue | Municipal Blue Water |
| 1 | Water Source | watsourcemunicipalunk | Municipal Water (Origin Unknown) |
| 1 | Water Source | watsourcesea | Brackish surface water/seawater |
| 1 | Water Source | watsourcecond | Condensate from External Steam Source |
| 1 | Water Source | watsourcerain | Rainwater |
| 1 | Water Source | watsourcemunicipalgrey | Municipal Grey Water |
| 1 | Water Source | watsourcerecycle | Recycled Water |
| 1 | Water Source | watsourcereuse | Reuse Water |
| 1 | Water Source | watsourcewaste | Treated Wastewater from External Source |
| 1 | Water Source | watsourcewasteinternal | Untreated Wastewater from External Sources (treated internally) |
| 1 | Water Source | watsourcesurface | Surface Water |
| 1 | Water Source | watsourceground | Groundwater |
| 1 | Water Source | watsourcemunicipalblue | Municipal Blue Water |
| 1 | Water Source | watsourcemunicipalunk | Municipal Water (Origin Unknown) |
| 1 | Water Source | watsourcesea | Brackish surface water/seawater |
| 1 | Water Source | watsourcecond | Condensate from External Steam Source |

| 1 | Water Source | watsourcemunicipalgrey | Municipal Grey Water |
| 1 | Water Source | watsourcerecycle | Recycled Water |
| 1 | Water Source | watsourcereuse | Reuse Water |
| 1 | Water Source | watsourcewaste | Treated Wastewater from External Source |
| 1 | Water Source | watsourcewasteinternal | Untreated Wastewater from External Sources (treated internally) |
| 2 | Facility Type | finalProductAssembly | Finished Product Assembler |
| 2 | Facility Type | printingProductDyeingAndLaundering | Finished Product Processing (Product Printing, Product Painting, Product Dyeing, Product Laundering and Product Finishing, Embroidery & Embellishments) |
| 2 | Facility Type | hardComponentTrimProduction | Component / Sub-Assembly Manufacturing (incl Packaging) (e.g. Label, Zipper, Snap, Button, Elastic Buggie, cardboard, etc) |
| 2 | Facility Type | materialProduction | Material Production (Raw and intermediate materials are transformed into their final state before assembly) (e.g. Fabric dye-house, Fabric manufacturer, Yarn Dyeing, PCB manufacturer, etc) |
| 2 | Facility Type | rawMaterialProcessing | Raw Material Processing (Raw Materials are processed into intermediate material products) (e.g. Yarn Spinning). |
| 2 | Facility Type | rawMaterialCollection | Raw Material Collection & Bulk Refining (Materials are collected/extracted/farmed and refined to bulk commodity state) (eg. Cotton Farming and Ginning, processing of bottles, fabric scrap, etc.. into new recycled material) |
So the raw value for usage of surface in Raw Material Collection & Bulk Refining for production would be found in either the ref_id wattrackwatsourcesurfaceprodrawMaterialCollectionquant or wattrackwatsourcesurfaceallrawMaterialCollectionquant the former if ensourcetracksepdomprod is Yes the latter if it is no and then combined with domestic water use but never both.
