Water is an essential part of the Company’s operations and our water is from public sources. We treat a significant portion of that water to produce the high purity deionized (DI) water necessary for our manufacturing operations. We carefully monitor our water usage at each of our operating facilities and have set a water use reduction goal of 2.5% by 2020, relative to the 2015 baseline year. Due to production growth, our 2017 total water withdrawal increased by 7% from 2015. We also monitor our water use intensity by normalizing our fabrication site’s water withdrawal to our production output. In 2016, our water use intensity increased by 13% from 2015, driven by site expansion construction activities. Our 2017 water use intensity was virtually unchanged compared to 2015, but compared to 2016, it went down by 12%.
|We have water use reduction programs, including water recycling and reuse, implemented at our manufacturing facilities in support of our 2020 goals. On an average, 30% of our annual water withdrawal from 2015 to 2017 was reused or recycled. Collectively, we have recycled over 110 million gallons of water in 2017.|
The chart below show the company’s water withdrawal, both absolute and normalized, from 2015 up to 2017.
In our Ireland ERDC Building, there are ongoing projects to reduce water consumption and reuse water streams where possible, e.g., recycling of RO (Reverse Osmosis) and UF (Ultra-Filtration) concentrate within the site water plant. As part of the ERDC Building a rainwater harvesting system was introduced as a source of water for certain facilities within the building to reduce the burden on the main water supply. Numerous water meters have also been installed around the campus to track and trend water usage to allow for early intervention should leaks arise.
Wastewater discharge by quality and destination is monitored at the site-level but not rolled up at the corporate-level. Wastewater discharged from our manufacturing facilities is generally sent to the municipal treatment plant, in accordance with local legal requirements. For the past two years, we’ve seen an increasing trend in the amount of water used in our operations driven by an increase in production volume requirements.
