Published December 2016 | Updated August 2024
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 are targeting 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 City of Industry (COI), California is a key contributor to these goals. The COI plant primarily produces industrial cleaning and sanitizing chemicals. Located in Southern California, in the San Gabriel sub-basin, the COI plant relies on water distributed by water treatment plants that source water from Colorado River aqueduct and California aqueduct. Recycled water from COI is discharged from the site to the San Jose Creek Water Reclamation Plant then to a portion of the San Gabriel River and ultimately empties into the Pacific Ocean. Non-recycled wastewater discharged to the Joint Water Pollution Control Plant (JWPCP) in Carson, CA. The treated water from the JWPCP is sent to the Pacific Ocean off the Palos Verdes Peninsula.
After Ecolab’s 2014 water risk assessment, the COI plant was identified as 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:
- Installation of volumetric flow meters on the boiler feedwater tank, reverse osmosis unit, cooling tower and deionized water system to better track on-site water use.
- Installation of Water Flow Intelligence and Smart Water Valve to provide greater visibility and insight into water use and improvement opportunities.
- Upgrades to bottle washers to reduce water and optimise wash quality.
- Optimization of production scheduling to minimise washouts and reduce unnecessary washout cycles.
- Instillation and improvements in mixing sprayballs with timers reduce water.
- Implementation of an idea collection system to gather water-saving ideas from all plant employees. This encourages all associates to view water as a shared resource and drives collective action that feeds into water-savings discussions during monthly business reviews.
- Continuous improvement of the washout water programme to capture and reuse the first rinse for manufactured products.]Reduction of water used for landscaping.
- Review and relaunch of the on-site water safety plan.
- Enactment of a dry floor policy to reduce the amount of washdown that occurs during filling.
Outcomes
As a result of these actions, the COI plant achieved savings in water and energy use. The improvements made at the site have proved to be a helpful step forward for enhancing the site’s operations and advancing Ecolab’s sustainability goals.Featured Solutions
Leveraging Ecolab solutions and digital technologies help the COI manufacturing facility reduce, reuse and recycle water.

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, the company decided to implement the Alliance for Water Stewardship (AWS) International Water Standard at its Carson plant in 2016 and version 2.0 in 2020. The facility has continued to stay up to date on AWS requirements to uphold the core certification.
To identify shared water challenges in the San Gabriel sub-basin, a comprehensive risk assessment was performed leveraging insights from Ecolab’s Smart Water Navigator, and the World Resources Institute (WRI) Aqueduct Atlas to identify shared and site-level water challenges.
Ecolab’s water stewardship approach aims to make a positive impact within our operations and on the water challenges within the communities we operate in. Primary shared challenges between the plant and relevant, local stakeholders include water scarcity due to reduced snowpack from existing water sources, aging water infrastructure, urban water runoff, water quality, groundwater overdraft, saline intrusion into groundwater and loss of wetlands and species. Additional shared challenges include seismic risk and wildfires. To address the primary shared issues, Ecolab collaborates with other water users in the basin, two of which are Ecolab facilities, a site located in Placentia, California and AWS-certified plant in Carson California.
To effectively address these challenges, Ecolab’s water stewardship approach includes advancing progress toward the five outcomes outlined by the AWS standard. Ecolab strives for continuous improvement in the site’s water balance and water quality. Beyond our operations, our comprehensive strategy includes a focus on regional important water related areas (IWRA) and Water Sanitation and Hygiene (WASH). Continued progress across these key focus areas depends on robust water governance across the site and enterprise operations.
Using the Ecolab Smart Water Navigator to quantify the progress made against the five AWS outcomes, the COI site 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 incorporates 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
Net Positive Water
A sustainable water balance and smart water management approach within our own operations is a critical component in achieving a localized 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 COI plant assessed the facility 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 Approach
To maintain good water quality of both process water and wastewater, internal daily water testing is conducted in addition to third-party wastewater testing every three months. Water is treated, stored onsite and tested to ensure quality standards are met prior to entering the municipal wastewater stream.
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, a review by the leadership team, documentation in an internal reporting platform and communication of mitigation strategies during monthly site meetings. Additionally, learnings are used to create new control systems to prevent similar incidents from happening again. This approach ensures the maintenance of top-tier water quality and safety standards.
Water Governance
Water Governance Approach
At the plant level, the Safety, Health and Environmental (SHE) department is responsible for wastewater compliance. The site’s production supervisors are responsible for wastewater discharge and PH monitoring. Additionally, the SHE manager is ultimately responsible for pH monitoring, wastewater compliance and the plant manager is accountable for overarching wastewater compliance. The corporate environmental lead is available to consult on regulatory updates and wastewater compliance. Site water-related compliance information is available upon request, including necessary corrective action taken by the site to prevent future occurrences. Additionally, Ecolab's CDP Water Security report discloses any violations and associated corrective actions.
At a corporate level, the corporate sustainability team is guided and advised by the Sustainability Executive Advisory Team (SEAT), which is made up of the company’s most senior business and divisional leaders. In addition, Ecolab’s Sustainability, Water Stewardship and Safety, Health and Environment (SHE) positions are publicly available and serve as commitments to and guidance on water-related issues and compliance. Ecolab’s Sustainability Position formalizes Ecolab’s global commitment to sustainability within the company and its impact on customers. Ecolab’s Water Stewardship Position reinforces Ecolab’s global commitment to responsible water stewardship by identifying opportunities for the company and its customers to use water resources in a manner that benefits business, communities and nature. Ecolab’s SHE Position outlines the company’s commitment to excellence in safety, health and environmental practices and performance across global operations.

Collective Action
In addition to internal operational improvements, Ecolab’s COI plant’s external water stewardship activities are ongoing. To address these primary shared water challenges, Ecolab collaborates with other water users in the basin as well as the Rowland Water District.
Since 2005, the City of Industry Ecolab Foundation Nonprofit Grant Programme has supported local nonprofits aligned with the focus areas of the Ecolab Foundation: Youth & Education, Civic & Community Development (basic needs: food, housing, workforce development), Environment & Conservation and Arts & Culture.
In 2023, 18% of the funds granted supported Environment & Conservation nonprofits, including Orange County Coastkeeper and their WHALES programme that focuses on hands-on environmental education to underserved junior high and high school students in Orange County, as well as Nature for All, that partners with volunteers and other community entities to nurture greenways with native trees and plants to help protect the local environment. Both of these organizations are in the catchment that help maintain and better IWRA through volunteerism and education. Other grants included stakeholder groups like the Boys and Girls Clubs, Food Bank of Southern California and Project Scientist.
Additionally, through Ecolab’s Global Community Giving Programme, COI team members participated in multiple volunteer and outreach events including a watershed cleanup with the Huntington Beach Wetlands Conservancy, of which the Huntington Beach Wetlands are one of our identified IWRA, as well as packing food for those experiencing hunger and helping sort toys donations for families in need during the end of year holiday season.
Ecolab continues our work as a founding member of the Water Resilience Coalition (WRC). In 2023, Ecolab stepped forward as the Basin Champion for one of the WRC's priority basins: California – obviously containing our site's catchment. As Basin Champion, Ecolab convened corporations, nonprofits, and governmental bodies to launch the California Water Resilience Initiative (CWRI). In line with California's Water Supply Strategy, this initiative aims to shore up and advance efforts to close the projected water supply deficit in the state through public-private partnerships. Since its launch in October 2023, Ecolab and other leaders of the initiative have begun building a roadmap of high-impact projects in need of corporate investment and engagement to reduce, reuse, and replenish water in the region. The CWRI aims to serve as a leading example of how corporations can help California reach its water goals. Through this important initiative, Ecolab is partnering across sectors to promote resiliency for communities, the economy, and ecosystems.
In 2023, the Ecolab Foundation pledged $157,000 to a project of the Pacific Institute, in partnership with the Bonneville Environmental Foundation, Sensor Industries and other local southern California water agencies and housing providers, to tackle water waste using an innovative toilet leak detection system.
Multiple water replenishment projects were funded and executed between 2020-2024 across Ecolab that impact the Southwest United States. These replenishment projects, such as the Colorado River Indian Tribes (CRIT) System Conservation Project, allow Ecolab to collaborate with other stakeholders to reduce the impact and severity of water shortage declarations of our catchment's primary water sources.
Ecolab is involved in the California Water Action Collaborative (CWAC) and is also part of the South Coast working group (within CWAC). The Ecolab team participates in monthly meetings to keep pace on shared water challenges and efforts in California. Ecolab is actively seeking collective action projects in the region that align with corporate replenishment goals.
Ecolab is a member of a public policy water resources group in Washington D.C. that advocates for water resource policy with a heavy focus in California. Ecolab continues to engage with and support the Alliance for Water Stewardship’s global work by sharing the company’s water stewardship strategy through multiple speaking engagements, AWS webinars and encouraging other large multinational corporations to join AWS.
On top of local water stewardship efforts, Ecolab’s global giving programme, Solutions for Life, enhances the company’s mission to conserve and protect fresh water through partnership and additional projects with The Nature Conservancy and the Project WET Foundation.
