Water management across geographical regions North America
East Asia
EMC: identifying water-related opportunities. In its owned and operated facilities, EMC looks at energy, water and carbon emissions holistically. By driving efficiencies in its products and in its data center operations, EMC aims to reduce both electricity and water. Application of free air cooling technology in EMC’s data centers and labs has allowed the company to reduce both power and water consumption. EMC has a plan to conduct a corporate water footprint analysis to understand quantitatively the linkages and trade-offs between water and carbon emissions, and to pursue strategies to minimize the company’s overall impact on the environment.
Europe
Danone: building water management into site selection and operation. At Danone, choosing a new production site is subject to an assessment of the sustainability of water resources. Danone’s assessment includes examination of water availability for quantitative/ qualitative aspects; tap water access in quantity and quality; governmental programs for provision and development of sanitation; the local regulatory framework; the extent of water stress; and community and public relations issues related to water access. Continuous monitoring and free drinking water access for locals are part of continuous site operation policies. Other Danone divisions have begun mapping local water stress, a process that should be completed by 2012.
Sony: groundwater recharge. Since 2003, Sony Semiconductor Kyushu Corporation Kumamoto Technology Center (Kumamoto TEC) has been working with the local community, environmental NGOs, farmers, and agricultural cooperatives to improve groundwater recharge, where water penetrates into the soil and ultimately returns to the aquifer. In fiscal year 2010, Kumamoto TEC recharged more than 2.04 million cubic meters of water, which is more than its annual consumption of water.
Southeast Asia & Oceania
Woolworths Limited and rainwater harvesting. Woolworths Limited implemented rainwater harvesting at two distribution centers that use water based cooling towers, saving 16.4 million liters of water in 2010. Suitability of cooling systems is assessed and designed to meet climatic regions where they will be most effective. Extensive work and investment has occurred in refrigeration and air conditioning, maximizing energy efficiency and low carbon technology and reducing any carbon cost of not using water- based systems. These investments have reduced carbon emissions by 500,000 metric tons in addition to water savings.
Latin America
VALE: water efficiency and recycling/reuse. VALE has intensified its efforts to increase process efficiency and to reuse water. As a result, in 2010, the water reuse and recirculation rate throughout VALE ‘s operations
was approximately 79% of the water volume used in the processes. In 2010, VALE carried out water efficiency surveys in five areas which represent approximately 40% of the total water withdrawal volume in Brazil, and these studies will be extended to other units in 2011. The studies have identified process improvement opportunities to increase water efficiency.
Africa
Anglo Platinum: reducing water withdrawals and engaging communities. Anglo Platinum’s water strategy aims to have “zero-potable water” use in their process operations (excluding domestic use demand). Through various initiatives including site process water recycling and recycling of sewage water from nearby communities, the company’s potable water usage decreased by 12% in 2010 from 2008 levels. Anglo Platinum has also invested in upgrading municipal wastewater treatment facilities and supplying drinking water to certain schools and neighboring communities.
South & West Asia
ITC: protecting soil moisture in India. ITC participates in a soil and moisture conservation program by investing in water harvesting systems, efficient irrigation practices, agricultural science research, and by strengthening institutional structures and local watershed management groups. The program provides soil and soil moisture conservation to nearly 65,000 hectares in some of India’s moisture-stressed areas.
