Corporate Water Footprint of an industrial maintenance services company
Climate change is a global issue, reason why various countries have focused their policies into the protection and prevention of their impacts, reducing their emissions. However, this environmental impact is not the only threat to our planet. Numerous river basins all over the world face water scarcity, contamination and depletion of surface and groundwater reserves. This water crisis has thus mobilized researchers to create indicators and certifications to convey the impacts of human water usage.
To correctly execute water management, it's key to know how much water is needed to produce an item or service. Water Footprint measures the consumption of fresh water that includes water consumption from surface and groundwater sources, rain water (for harvest) and consumption required to dilute liquid emissions. This indicator can consider direct usage as well as indirect usage of a consumer or product.
The direct operational water footprint of an industrial maintenance services company was estimated for the 2021-2022 period, to evaluate the direct usage of the water resource of the company, and communicate the results to clients and stakeholders. The Water Footprint Network methodology was used, which divide the results in green, blue and gray water footprint.
Data of water consumption of manufacturing activities were used, such as support of maintenance site areas, administration, staff training, laboratory, sanitary facilities and canteens; as well as the management of wastewater from modular toilets and the site's septic tank.
Generally, it was observed in the results that a considerable part of blue water footprint emerged from the water consumption of the staff's shower facilities, followed by pumps tests. While for the gray water footprint, the greatest intake was from septic tank emissions. In both instances, the best opportunities for improvement in resource management were identified, such as maintenance procedures.
In the water footprint report, the conclusion and recommendations were included based on the analysis' findings.
