                      this strategy will significantly reduce the mass and volume of
                      shipments, thus reducing transportation energy use.
                    • Reduce unnecessary flow-through of water by installing de -
                      vices, such as automatic shutoff valves, flow reducers, and
                      waterless urinals, and by shifting to low-water landscaping
                      methods.
                    • Utilize alternative, lower-quality sources of non-potable water
                      for industrial operations in order to reduce demand on munic-
                      ipal water supplies.
                    • Implement water treatment processes beyond compliance
                      requirements in order to enhance the quality of wastewater
                      discharges.
                    • Find beneficial secondary uses for process wastewater, such
                      as floor maintenance.
                    • Collect rainwater as an alternative source of fresh water.

                   Many companies have emphasized water management programs
               as part of their overall sustainability commitment (see the Coca-Cola
               case study in Chapter 15). Going beyond facility water usage, life-
               cycle assessment methods are increasingly being used to assess the
               overall water “footprint” of a company’s value chain from supplier to
               consumer (see Chapter 9).
                 Example: Intel Corporation uses ultra-pure water in its semiconductor fabrication
                 plants, some of which are located in water-stressed areas such as Arizona and
                 Israel. The Corporate Industrial Water Management Group supports the operating
                 sites in implementing local strategies for sustainable water use. For example,
                 at Intel’s Chandler, Arizona facility, treated process water is sent to an off-site
                 municipal treatment plant, brought up to drinking water standards, and reinjected
                 into the underground aquifer at a rate of about 1.5 million gallons per day.
               Ecosystem Integrity, Biodiversity, and Land Conservation
               Ecological resources, including biomass, water, and genetic diversity,
               are nurtured in the world’s ecosystems, which span a vast range of
               geographies and climates. Each ecosystem is unique, and contains a
               network of species that have adapted to the local or regional condi-
               tions. Instead of simply building facilities, occupying land, and ignor-
               ing the surrounding ecosystems, business entities can interact with
               them in several ways:
                    • Harvest resources, such as water, crops, or wood, without ex -
                      ceeding the capacity of the ecosystem to renew those resources.
                    • Protect resources by limiting vehicular traffic, creating buffer
                      zones for sensitive habitats, and avoiding pollution or waste
                      that would disturb the ecosystem.
                    • Restore damaged resources by reintroducing native plant and
                      animal species, removing artificial barriers such as dams,
                      and treating polluted water.
