How management & conservation of water resources can be done?

Answer 1

here is an example for management & conservation of water resources done by Intel's.

A sustainable water resource is essential for a healthy community, balanced growth, a high quality of life and Intel’s business. With some of our key manufacturing sites in arid locations, we recognize that prudent water management is an essential component of our overall business success.

Water Management and Conservation

Our approach to water management starts at the top with the commitment of our senior executives to lead the way in environmental management. We view water management from a holistic, life-cycle perspective. Early in our site selection processes, we look at the water supply necessary to run our operations. We then examine how we use water in our operations. We have a team of dedicated water engineers who work to increase the water efficiency of our operations and look for opportunities to save water in everything from making ultra-pure water for our manufacturing processes to how we use water in our landscaping and restrooms.

Using the input of our hands-on water engineers, our strategic management council drives capital improvement projects for new manufacturing process technologies and sets water conservation priorities as part of factory planning. Because our business demands continuous process improvements, we have frequent opportunities for new water-efficiency projects. In addition, our new 300mm process uses 40% less water for each square centimeter of wafer surface area than the previous 200mm wafer technology.

Intel has made a long-term commitment to maximize the reuse of wastewater in our operations and drive further efficiency from our ultra-pure water plants. As a result, we have reduced our operational requirements for fresh water by approximately 35%. While our ultimate vision is to some day see the continuous reuse of water in semiconductor manufacturing, we currently discharge water from our operations according to local permits. Those discharge methods vary from site to site based on the needs of the local community. We partner with the local water management agencies to determine the best solutions for each location.

In 2005, Intel adopted a new water conservation strategy that focuses not only on our internal efforts but also on how we can:
Share our expertise and learning with other businesses.
Promote water conservation education and awareness in our local communities.

Collaborate with universities, water suppliers, governments and water users to solve the most pressing regional water challenges.
