Making an Impact: Water Withdrawal Reduction

Making an Impact: Water Withdrawal Reduction

Water Stewardship in Mexico

In 2023, we executed multiple water conservation projects at our sites in Monterrey and Reynosa, Mexico, both of which are in high water-stress locations as identified by the World Resources Institute Aqueduct. At our Monterrey site, we reduced water withdrawal by approximately 64 percent in 2023 from the 2022 level by upgrading our water reuse system, increasing the recovery of water in our RO system to reduce waste, and optimizing operations to decrease water required for ice machine testing. At our Reynosa site, we integrated multiple Pentair solutions to reduce water withdrawal such as the Pentair X-Flow ultrafiltration ("UF") membrane, Pentair water softeners, and Pentair Hydrocarbon Recovery Technology ("HRT"). The projects resulted in a water withdrawal reduction at the site of approximately 23 percent in 2023 from the 2022 level.

Water Conservation in the Netherlands

In 2023, we implemented several water conservation projects at our Enschede, Netherlands site. These included upgrading the RO system to increase recovery, reusing water in the membrane post-treatment process, and reusing condensate from the evaporator. With these projects, the site reduced its water withdrawal by approximately 29 percent in 2023 from the 2022 level.

Water Reduction in Wisconsin

At Pentair's Bishop Woods site in Brookfield, Wisconsin, we conduct performance testing on a wide range of water filtration systems and components. Many of the tests require specific water chemistries to comply with third-party certification standards. In 2023, we adopted new ways we could conserve water, without compromising the integrity of the tests. This included creating and implementing a closed-loop system for select types of product testing, which allows for a reduction in water usage.

Additionally, in our mechanical lab, we completed a project that now allows us to utilize the concentrate from our laboratory RO system for all mechanical lab testing. Lastly, we increased water efficiency in the mechanical lab by precisely monitoring and controlling water temperature for testing. These water conservation projects enabled the site to reduce water usage by approximately 22 percent in 2023 from the 2022 level.

We look forward to continuing and improving upon these dedicated efforts to conserve and reduce water usage across the organization as we help the world sustainably move, improve and enjoy water, life's most essential resource.

Making Better Essential

At Pentair, our sustainability efforts are guided by Making Better Essential. The decisions we make, the products we create, the solutions we offer, and the partnerships we form, are opportunities to make the world better. Central to our purpose, we take this responsibility seriously as we believe that making life better for people and our planet is essential.
