2. Consultant Needs California CII water use volumes by NAICS or sector California Case studies California CII contacts (trade organizations, industrial experts, etc.) TF input and information Data from California DWR EPA, etc. and other sources (consultants will need to make in contacts) 2

3. 2009 State Water Plan February 2008, Governor calls for 20% reduction in per-capita urban water use by 2020 To reach this target, all water users, including the CII sector will need to do their part CII water use in California estimated to be approximately one-third of total water use in the State’s urban areas 3

10. BMP Development Commercial – Institutional Matrix or Technologies Approach Similar format to EBMUD Guide Industrial – Manufacturing More descriptive format for specific industries, but would contain a technologies section for commonly found processes such as cooling towers, boilers etc. 10

11. Similar BMP Efforts – Past & Present Texas (2004) New Mexico (1999) North Carolina (2009) U.S. EPA – WaterSense Program (2011) 11

12. U.S. EPA WaterSense Program Development of Comm’l-Institutional BMPs No industrial Work now underway 32 categories Commercial food service equipment (10) Plumbing (4) Building systems (3) Landscape & irrigation (2) Education & management (2) Medical & laboratory (2) Alternate water sources Other (8) 12

13. Example BMP from WaterSense Best Management Practices for Boiler/Steam Systems Operations and Maintenance Options Obtain the services of a water treatment specialist to prevent system scale and corrosion and to optimize cycles of concentration. Treatment programs should include periodic checks of boiler water chemistry.

14. Outline for Report Commercial & Institutional Brief description of water using sector in California Estimate of water use by sector (where available from existing sources) Description of how water is used by use technology 14

15. Outline for Report (cont’d) Commercial & Institutional Matrix of technologies associated with CI sector Technology BMPs Technology description Technology best practices to save water Discussion of potential water savings per operation Potential cost differences Recommended BMP’s 15

16. Outline for Report Industrial Overall discussion of industrial sector Major water industries addressed Industry-specific information How water is used by sector Description of industry specific BMP’s Reference to technology section for common water using technologies (boilers, cooling tower, water treatment, etc.) Summary of BMP’s and recommendations 16

17. A Look At Alternate Sources There is significant opportunity to use both recycled water and water collected from on-site sources. Within the context of a BMP for CII, the focus should be on how can the CII water user evaluate the viability of these sources. This will be covered in a chapter on Alternate Sources of Water. It will include information on both recycled municipal wastewater and on-site sources ranging from rainwater harvesting, to use of air conditioning condensate, to complete on-site recycling. 17

18. Specific Legislative Points Evaluation of public infrastructure necessary for delivery of recycled water to the CII sectors. Evaluation of institutional and economic barriers to increased recycled water use within the commercial, industrial, and institutional sectors. 18

19. Difficulties Evaluating Recycled Water Lack of a central repository of information about recycled water infrastructure No one set of economic values for a state with such a variation in water costs TF members input critical for input regarding case studies and other background data to assist in answering that section of the Legislation. 19

20. A Look At Alternate Sources Outline Description of Possible Sources Information on Water Quantity & Quality Considerations What the CII user should know to evaluate the potential Sources of Information and Assistance 20
