  1. HOW TO HELP YOUR LOCAL BUSINESSES AND INSTITUTIONS Judy Adler, P.E.

  2. ICI Definitions Industrial • manufacturers or processors of materials • e.g. textile, pulp and paper, metal finishing Commercial • provide or distribute a product or service • e.g. hotels, restaurants, office buildings Institutions • dedication to public service (regardless of public/private ownership) • e.g. schools, churches, hospitals, government facilities (including water and wastewater utilities)

  3. Characteristics of the ICI Sectors • Heterogeneous • Highly variable water use patterns • Wide variety of water uses • Factors that affect water use can be complex • Wide variety of water efficiency measures • Difficult to establish standard for water efficiency without a site-specific audit

  4. What is P2AD ? • A non-regulatory division of the Georgia Department of Natural Resources • P2AD provides confidential, free assistance to clients who want to reduce resource usage, waste, and emissions. • These services are available to all Georgia manufacturers, commercial businesses, and institutions

  5. Department of Biological and Agricultural Engineering (BAE), University of Georgia • Economic Development Institute (EDI), Georgia Tech Georgia Environmental Partnership • Pollution Prevention Assistance Division (P2AD)

  6. P2AD Water Efficiency Services • Water audits • On-site water efficiency assessments • Facilitation of water efficiency teams • Information center • Workshops and in-plant training • Recognition programs

  7. Water Management Hierarchy Don’t put all your efforts on the backend!

  8. Water Reuse Wastewater Treatment/Water Supply Water Management Hierarchy Water Efficiency (Source Reduction) Increasing Cost

  9. Benefits of Water Efficiency for ICI Customers • Reduced water demand • Water and sewer cost savings • Wastewater treatment savings • Energy cost savings • Improved product competitiveness • Easement of regulatory burdens • Reduced environmental impact • Enhanced company image $

  10. Steps for a Successful Water Efficiency Program • Step 1 – Establish commitment and goals • Step 2 – Line up support and resources • Step 3 – Conduct water audit • Step 4 – Identify and prioritize water management options • Step 5 – Prepare a plan and implementation schedule • Step 6 – Track results and publicize success

  11. Concentration vs. Mass Based Limits Actual Flow Flow Limit BOD Limit Actual BOD

  12. Water Audit • Objective: assess water uses and costs • Collect background information • Walk-through survey • Flow meter readings • Water balance • Determine true cost of water • Water and sewer bills • Energy for heating water and pumping • Wastewater treatment costs • Water treatment costs • Capital costs for equipment • Regulatory and liability costs

  13. Water Balance - Food Processor Example Misc. 1% Unknown Leaks 6% 2% Process Uses 13% Domestic 3% Cooling/ Heating 19% Once-through Washing/ Cooling Sanitation 14% 42%

  14. Common Water Efficiency Measures • Recycle process/cooling water • Plumbing fixture retrofits/replacements • Adjust cooling tower blowdown • Repair leaks • Landscaping conservation techniques • Install high pressure, low flow/automatic shut-off spray nozzles • Turn off equipment when not in use

  15. Simple behavioral modifications can have a huge impact!

  16. ICI Conservation Incentives • Free audits and technical assistance • Rebates • Pay for performance • Grants • Ordinances • Education and Training

  17. Austin, TX Rebates • Up to $40,000 for special projects • Toilets (up to $110), urinal flush valve ($30) • Rainwater harvesting (up to $40,000) Services • Water conservation audits and assessments • Landscape audits • Awards and recognition program Tax Incentives – sales and property taxes

  18. Albuquerque, NM • Large Users (>50,000 gpd) Water Conservation Ordinance adopted in 1998 • Existing users must convert to low-flow fixtures by 2004 • New and existing users must submit a water conservation plan for approval including baseline, goals, measures, etc. • Landscaping requirements of any new development (except single-family) • Option 1- 20% high water use plants; remaining 80% must be low or medium water use • Option 2- water budget based on landscaping square footage; usage over budget surcharged

  19. Albuquerque, NM • City-owned properties required to use drought tolerant plants. Water budgets set for public parks and public and private golf courses • Internal Water Conservation Campaign to reduce City government use by 30% • Reduce of unaccounted-for-water (UAW) from 12% to 7% by the year 2004

  20. Wellstar Health System LaundryMarietta, GA • Installed a water reuse system • Reduced water consumption by 85% = 34 million gallons per year • Reduced wastewater discharge by 95% • Reduced energy costs to heat water by 30% • Cost savings = $253,943 • Payback = 1 year • 2002 Governor’s Award Winner

  21. Unilever Home & Personal CareCartersville, Georgia • water conservation task force • reuse non-contact cooling water and collected rainwater in manufacturing processes • 77% reduction in effluent volume • $20,000/year in potable water savings • $85,000/year in savings for testing, maintenance, and labor fees • P3 Partner, 2000 P2AD Governor’s Award Winner, and 2000 & 2001 GW&PCA Award Winner

  22. Golden State Foods Conyers, GA • Set up waste reduction/water conservation team • Employee participation by connecting water conservation to individual employee evaluation process • Reduced flow to wastewater pretreatment plant by 2.7 million gallons in 1998 • Saved $19,000/year in purchased water costs • Saved $25,000/year in wastewater pretreatment costs • P3 Partner and 1999 Governor’s Award Winner

  24. Considerations for developing an ICI conservation program What is the percentage of ICI water demand for your system? Who are the top users in your customer base? Advantages • Fewer customers to target • Potential water savings are greater per customer compared to residential Disadvantages • More $ per customer compared to residential • Requires staff with technical expertise
