Ecolab’s Santiago, Chile, Plant
Alliance for Water Stewardship (AWS) Case Study
Insights
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 the Lampa district of Santiago, Chile, is a key contributor to these goals. The Santiago facility is a blend plant dedicated to manufacturing disinfectant and detergent products, along with specialized solutions for heavy industry applications. The Santiago facility primarily utilizes water sourced directly from the Maipo-Mapocho Aquifer, an essential part of the Maipo River Basin. Ecolab holds rights for groundwater extraction and operates its own system to draw water from a well located on the property. The Santiago facility has an on-site wastewater treatment plant dedicated to treating domestic effluents using a sequential batch reactor (SBR) with activated sludge to reduce organic matter. The treated, clarified water is disinfected through chlorination and dichlorination, to meet regulatory standards. This treated water is then recovered in the fire protection system for reuse. Industrial liquid waste is managed externally by Bravo Energy, which handles and treats these specific residuals.
The Santiago facility was identified as a priority location to pursue AWS certification, enhance the site’s smart water management approach and implement innovative technologies to advance enterprise water goals.
Actions
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 improve the facility’s water balance and have been implemented to reduce overall water use:
- Optimization of the industrial reverse osmosis pretreatment system.
- Enhancements to water usage monitoring, which led to the identification and completion of a leak repair project.
- Improved batch production planning, which led to a reduction of mixer washes.
Outcomes
The improvements made at the Santiago site have proved to be an impactful step forward for enhancing the site’s operations and advancing Ecolab’s sustainability goals.
To improve the overall health of local watersheds, and as part of Ecolab’s efforts to create 2030 Positive Impact, we have prioritized AWS certification in high-risk watersheds in which we operate.

Water Stewardship Journey
Ecolab is committed to sustainable water use in our facilities and collaboration with other businesses at the local level. In alignment with Ecolab’s commitment to a holistic approach to water management across its manufacturing facilities, in 2024, the company achieved the Core Certification for Alliance for Water Stewardship (AWS) Version 2.0 International Water Standard at its Santiago, Chile, site. The Santiago site has continued to stay up to date on AWS requirements to uphold the core certification.
To identify shared water challenges in the Maipo River Basin, a comprehensive risk assessment was performed leveraging insights from Ecolab® Water Navigator IQ™ and the World Resources Institute (WRI) Aqueduct Atlas. Implementation of water withdrawal reduction projects were prioritized based on risk probability and impact to site-level and community stakeholders.
Ecolab’s water stewardship approach aims to make a positive impact within our operations and on the water challenges within the communities in which we operate. For the Santiago facility and local stakeholders, the top water-related challenges include water stress and scarcity in aquifers, water quality (including contamination of aquifers), areas without access to sanitation infrastructure, damage to protected ecological areas in the basin and flooding.
To effectively address these challenges, Ecolab’s strong water stewardship approach strives for continuous improvement in sustainable site water balance and water quality. Our holistic approach includes a focus on important water related areas (IWRA) and Water Sanitation and Hygiene (WASH), and our continued progress across all these critical areas depends on our strong water governance.
Using Ecolab® Water Navigator IQ™ to quantify the progress made against the five AWS outcomes, the Santiago facility is considered Water-Smart on the Water Maturity Curve. The Water Maturity Curve illustrates the quantified state of a site’s water strategy and management plan. A facility’s place on the curve is determined by a set of criteria that includes governance and strategy, target setting, water management practices and water stewardship. The criteria incorporate principles consistent with the five outcomes of the AWS framework, both emphasizing that strong water management includes continuous improvement and collaboration inside and outside the facility’s operations.
sustainable water balance
Sustainable Water Balance
Net Positive Water
A sustainable water balance and smart water management approach within our own operations is a critical component in achieving enterprise-wide net positive water impact. Aligned with the enterprise goals, the local team’s objective is to reduce the site’s annual water use per ton of product by 40% from 2018 to 2030. The team at Ecolab’s Santiago facility assessed the site for opportunities to decrease water use across operations to meet Ecolab's targets to create 2030 Positive Impact. Implementation of water reduction projects are prioritized based on risk probability and impact to site-level and community stakeholders.
water Quality
Water Quality
Water Quality Approach
To maintain high water quality at the Santiago site, reverse osmosis water quality is monitored continuously with sensors measuring essential parameters. For the site’s potable water, the site requires daily testing of free residual chlorine at key distribution points. Additionally, an annual physical-chemical and bacteriological analysis of the water source is conducted by an authorized laboratory.
Prior to draining stormwater and discharging wastewater, facilities must visually inspect and test the effluent to confirm that it meets the local environmental requirements, permit limits or company standards. If there are no local environmental requirements or permit limits, company standards must be met for stormwater discharge into an adjacent waterway or wastewater effluent into a city sewer system. If a spill or water-related issue were to occur, the site has a robust incident response plan that includes a root cause analysis of the original incident, documentation in an internal reporting platform and communication of mitigation strategies. Site water-related compliance information is available upon request.
Water Governance

Collective Action
In addition to internal operational improvements, Ecolab’s Santiago facility’s external water stewardship activities are ongoing. Shared challenges between the plant and relevant local stakeholders include water stress and scarcity in aquifers, water quality (including contamination of aquifers), areas without access to sanitation infrastructure, damage to protected ecological areas in the basin and flooding. To address these shared issues, Ecolab collaborates with other water users in the basin.
In 2024, Ecolab partnered with the Bonneville Environmental Foundation to implement a water use reduction project in the Maipo Basin. This multi-year project will help facilitate the conversion of irrigation systems on agricultural land from standard irrigation to drip or pivot irrigation. The project helps preserve the limited water supply for urban and agricultural use in the basin. Efficient water use is critical for helping maintain the balance of the local ecosystem. It also helps ensure that water remains available for other essential uses, including drinking and sanitation.
In 2025, as part of our recent volunteering efforts for World Environment Day, the facility participated in an educational visit to the Batuco Wetland (Humedal de Batuco), one of the IWRAs identified in the catchment. During the visit, participants contributed funds to support improvements to the greenhouse at the Batuco Wetland Ecological Center.
On top of local water stewardship efforts, Ecolab’s global giving program, Solutions for Life, enhances the company’s mission to conserve and protect freshwater through partnerships and additional projects with The Nature Conservancy (TNC) and the Project WET Foundation.
