Ecolab’s Cuautitlán Izcalli, Mexico, Plant

As a global leader in water solutions and services, Ecolab remains dedicated to creating a more water secure future through smart water management, conservation and stewardship. By 2030 we plan to continue to achieve a Net Positive Water Impact through:

• Reducing, recycling and replenishing water at operational sites. We aim to reduce water impact by 40% per unit production across our enterprise from a 2018 base year.
• Protecting local watersheds by working to restore greater than 50% of our absolute water withdrawal volume at high-risk sites.
• Delivering outcomes through the Alliance for Water Stewardship (AWS) Standard by achieving AWS certification for Ecolab manufacturing sites located in high-risk watersheds.

Ecolab's manufacturing facility located in Cuautitlán Izcalli, Mexico, is a key contributor to these goals. The Cuautitlán Izcalli facility primarily produces industrial cleaning and sanitizing chemicals.

Its primary source of water is the Cuautitlán-Pachuca Aquifer. Domestic and industrial effluents are discharged into municipal drains that feed into the RÃo Cuautitlán after treatment.

The Cuautitlán Izalli facility was identified as a priority location to pursue AWS certification as well as to enhance the site's smart water management approach and implement innovative technologies to advance enterprise water goals.

To contribute to Ecolab's enterprise water goals, the local team's objective is to reduce annual water use per ton of product by 40% from 2018 to 2030.

The following projects help to improve the facility's water balance and have been implemented to reduce overall water use:

• Installation of a rainwater collection and purification system for use throughout operations
• Replacement of spray balls for optimized washout efficiency and to reduce wash water consumption
• Optimization of process equipment washout processes
• Reduction in water use for reverse osmosis and deionization system regeneration
• Improvements made to the hold tank washing system
• Installation of high-efficiency bathroom and locker room fixtures and valves

As a result of these actions, the Cuautitlán Izcalli site achieved savings in water and energy use. The improvements have proved to be a helpful step forward in enhancing the efficiency of the site's operations and advancing Ecolab's sustainability goals.
