Water Management

Lexmark is focused on efficiently managing water usage at our facilities and has established a 2020 goal to reduce water use by 8 percent from 2015. We saw a slight increase in water use, up 8 percent, in 2016. Increased use primarily resulted from changes in water reuse activities at our cartridge manufacturing locations.

Water Management Goals

Water Withdrawal

Water Management reductions

Water is used as part of Lexmark operations for three primary purposes: manufacturing and development, sanitation and heating, and ventilation and air-conditioning (HVAC) systems. Our water usage can vary due to the need to control temperature. As external temperatures rise, more water is needed to cool our facilities. While we cannot control the water usage related to external temperature, we can aggressively monitor, control and reduce water withdrawal where opportunities exist.

Lexmark has identified five of our reporting facilities to be overall medium to high risk water locations per the Aqueduct Water Risk Atlas. This information encourages us to focus on the regions highlighted as having the highest risk and work to reduce or maintain low consumption.

Water management program

Through the years, Lexmark has followed our corporate water plan which concentrates on multiple methods of saving water. As Lexmark assesses site water requirements and reporting boundaries, changes may occur on site; for example, designating new contacts for water management, utilizing fresh approaches to awareness of site water usage, and pursuing alternate water sourcing or conservation techniques.

Water history

Lexmark has a long history of water projects that have helped reduce water usage in our operations by over 50 percent when compared to 2005.

Water harvesting and reuse

Lexmark values water reuse and harvesting and has found ways to implement projects with this focus at multiple locations. Unfortunately, water reuse at our Boulder, Colorado, facility will cease in 2017 because the water quality needed for operations is not met by the current waste water treatment method. Water will be supplied by municipal sources going forward, providing the needed water quality as well as a cost savings.

The Lexmark campus in Juarez, Mexico, continues to utilize its robust on-site waste water treatment facility. In 2016, phase III of the project was completed. Shortly after implementation a filtration issue was discovered which affected reuse rates in 2016. The system was fully functioning by the end of the year, allowing water from chemically produced toner (CPT) production processes to be reused in the toner manufacturing process and cooling towers at a maximum rate. In spite of the setbacks, 30,194 m3 of water was reused in 2016, representing 18 percent of total water withdrawal on site.

In 2016, Lexmark broke ground on a bioretention and rainwater harvesting project in Lexington, Kentucky, in cooperation with Lexington Fayette Urban County Government (LFUCG), EcoGro, Ridgewater, Stantec and the University of Kentucky.

While larger in scale than a traditional rain garden, the rainwater harvesting system will act in much the same way. This depression in the ground will collect rainwater and filter it through a layer of sand. Water not needed for immediate use can be stored in one of two tanks—a three million gallon tank or a 500,000 gallon tank—for later use. The naturally soft water can be used in Lexmark’s cooling towers, boilers or chilled water system on site, reducing the need for chemically treated water in these processes.

Lexmark’s rainwater retention area will have some bioremediation value and will also act as a retention pond in slowing rainfall runoff in conditions when excess flow is discharged to the creek. In the vein of sustainable resource consumption, the pavement, rock and soil being removed for the project is being reused or recycled. Existing pipes and tanks already in place are being recommissioned for use in this project to gain further savings.

Water withdraws and discharges

Lexmark is concerned with the origin of our sourced water and where it ends up. We understand that access to clean, abundant and affordable water is a critical issue. We also understand that our commitment to responsible use of our water resources and protection of local watersheds helps to ensure that our local communities have access to these water resources. Most Lexmark facilities withdraw water exclusively from municipal water supplies and other water utilities.

* To the best of our knowledge, none of these bodies of water is recognized by professionals to be particularly sensitive due to their relative size, function or status as a rare, threatened, or endangered system. In addition, none supports a particular endangered species of plant or animal, or is considered a nationally or internationally proclaimed conservation area. None of these water sources is significantly affected by Lexmark water usage.

Planned discharges

Wastewater from Lexmark operations is primarily discharged to local utility systems for treatment. We discharge some water directly to nearby bodies of water in accordance with local laws and regulations. Lexmark’s discharge of environmentally neutral water to the Cane Run Creek that flows through Lexmark property in Lexington, Kentucky, has had positive impact. The wildlife that depends on the Cane Run Creek (an impaired surface stream that is particularly vulnerable in times of drought) benefits from the occasional addition of water so that fish, birds and other wildlife can survive during times when the water level in the creek is otherwise detrimentally low.

Water discharges are often assumed to be equivalent to total water consumption; however, in Lexington, discharge monitoring has shown that only half of our usage is discharged to the sanitary sewer system. The majority of the remaining water sourced is evaporated from our cooling towers, diverted to Cane Run Creek to benefit that ecosystem, or absorbed into the soil when weather demands require care for landscaping and athletic fields.

Unplanned discharges

In an effort to prevent negative impacts on the environment, Lexmark has established site-specific pollution prevention plans that encompass compliance with applicable environmental regulations; outline Lexmark’s proactive pollution prevention efforts; and address spill prevention, hazardous waste management, recycling, and water quality. These plans cover multiple pollution routes, including discharges to ground, air and water. Pollution prevention plans are in place at all Lexmark-owned manufacturing and research and development facilities worldwide.

Lexmark reported no significant spills in 2016. In an effort to continually improve our processes, we record and investigate all spills—regardless of size or impact—as directed by site ISO 14001 and OHSAS 18001 management systems and other corrective and preventive action programs. All water discharges (whether planned or unplanned) that are destined for the local utility or nearby bodies of water are closely monitored by site facilities and environmental teams that test for water quality.
