4 INTRODUCTION Water is an integral part of manufacturing facility operations and management. Primary uses for water in the U.S. manufacturing sector include: Processing Cleaning Cooling Diluting Transportation Energy PPC Developing a Corporate Water Management Strategy 4

5 INTRODUCTION Demand for reliable water sources will grow as supply diminishes over the next 15 years, highlighting the need for improved water management strategies. PPC Developing a Corporate Water Management Strategy 5

6 BARRIERS TO WATER MANAGEMENT Water flows below the radar of many corporate managers and corporate boards. The primary barriers to prioritizing improved water use efficiency are: Low cost of water Lack of awareness of risks posed by water scarcity and impaired water quality Poor understanding of the actions required to improve efficiency PPC Developing a Corporate Water Management Strategy 6

7 DRIVERS FOR WATER MANAGEMENT The business case for corporate water management for most organizations can include: Water cost savings Corollary benefits (i.e., energy savings) Risk management Financial Operational Product Reputational Regulatory PPC Developing a Corporate Water Management Strategy 7

8 WATER USES IN MANUFACTURING Cooling Cooling tower use & losses Evaporation Cooling process Blowdown Drift Leaks Removing impurities Water entrained in the airstream PPC Developing a Corporate Water Management Strategy 8

9 WATER USES IN MANUFACTURING Boiler make-up Steam Water losses Boiler blowdown Make-up Boiler Condensate Dependent on water quality» PH» TDS Blow down» Etc. Leakage Steam & water PPC Developing a Corporate Water Management Strategy 9

10 WATER USES IN MANUFACTURING Food & Beverage 1kg = 15,500 Gallons Manufacturing processes Consumption is highly sector specific Textile 1 pint 1 t-shirt Automotive = 20 Gallons = 6,600 Gallons Opportunities exist: - Process change (e.g. dry machining) - User behavior (training + awareness) - Reuse process water - Submeter end-uses 1 car = 39,000 Gallons PPC Developing a Corporate Water Management Strategy 10

17 TYPICAL SOLUTIONS Cooling Water Optimizing drift, blowdown, and leaks Consider a/c and refrigeration condensate water for make-up water New technologies Boilers/Steam Systems Minimize losses through steam traps and leaks Optimize blowdown through continual monitoring use of feedwater, condensate and steam Processes Measuring water use by process or product helps identify opportunities Recycled water Use of gray water for irrigation Biological treatment of water for re-use PPC Developing a Corporate Water Management Strategy 17

18 OWENS CORNING EXAMPLE Goal setting 35% water intensity improvement between Improved 27% through 2013 Voluntary reporting and disclosure CDP water program Global Reporting Initiative Use of Aqueduct software tool Learned that 32% of its facilities are in water-stressed locations Another 21% in future projected stressed locations Working with stakeholders in affected communities 50% reduction seen as Kansas City facility Targeting cooling tower blowdown and drift Replacing old boilers with steam generators Lots of little things PPC Developing a Corporate Water Management Strategy 18

19 SABMILLER EXAMPLE CORPORATE LEVEL Comprehensive look at water use across South Africa Found that 85% is for key crop production (barley, hops, maize) Risks identified Increasing temperatures/droughts leading to less available water Spread of invasive species in key watersheds & water catchments Urbanization water needs Opportunities & Solutions Improved monitoring of water use throughout supply chain Better Barley, Better Beer initiative (best practices) Removing invasive species in water catchment areas Identifying water efficiency opportunities Leak detection Drip irrigation Schedule optimization Partnering with World Wildlife Fund South Africa office PPC Developing a Corporate Water Management Strategy 19

20 SABMILLER EXAMPLE PLANT LEVEL SABMiller Brewery - Newlands, South Africa Actions taken Optimized water used for cleaning protocols established Filtered and sent to condensers for cooling water Measuring water use (now 120 meters in facility) Monitoring water use for pump seal cooling Results From 4.5 liters of water / liter of beer to 3.0 liters of water / liter of beer (facility only) in past three years Blue Drop certified Keys to Success Employee engagement awareness, recognition, $$ Daily meetings on water Weekly forum of engineers on water Monthly teleconferences with corporate and other 6 facilities in SA PPC Developing a Corporate Water Management Strategy 20
