  1. Water Balance Study Water Treatment, Management and Conservation Solutions

  2. Project Overview • Two Primary Objectives • Balance the Internal Water Usage with Purchased and Discharge Water Volumes. • Look for Opportunities To Reduce Water Usage and Conserve Utilities

  3. Methodology • Introduction and Site Survey • Compile Existing Information; Meter Readings, Site Drawings, Usage Estimates, Etc. • Generate List of Water Users by Department • Gather Purchased Water Usage Data • Preliminary Balance, Data Verification and Revisions • Final Water Balance • Provide Recommendations For Water and Energy Conservation.

  4. Resources Significant Information and Data are required to execute study • Introduction, Site Overview, Site Specific Details • Purchased & Discharge Water Data

  5. Resources Departmental Interviews • HDM – • LDD – • HVAC – • Sytech – • Wastewater Treatment – • LDD Tech Center – • Emissions Solutions –

  6. Resources • Drawings; • RB-28 – Water Meters & Mains • RB-28 (TIFFY) – Combined Sewer • RB-30 – Plant 1 Storm Sewers • RB-31 – Sewers Surrounding Facility • RB-65 – Parking Plan with Gate #’s

  7. Water Supply & Discharge • An Overview Of Water Sources and Discharge Points.

  8. Water Sources • There are nine (9) water meters being monitored by the city. They are designated as follows:

  9. Discharge Locations • There are seven (8) discharge points. They are designated as follows:

  10. Water Usage History The following graph depicts the increasing volumes of incoming water and discharge water since 2005

  11. Water & Sewer Cost Calculator

  12. Water & Sewer Cost History

  13. Water Usage Estimate • Interviewed Department Heads • Traced Water and Discharge Piping Lines. • Recorded and Verified Existing Meter Readings • Reviewed Historical Meter Readings. • Monitored and Verified Flow Rates with Portable Ultrasonic Flow Meter.

  14. HDM Usage Worksheet

  15. HDM Usage Chart

  16. LDD Usage Chart

  17. HVAC Usage Chart

  18. Wastewater Usage Chart

  19. LDTC Usage Chart

  20. Employee & Related Usage Chart

  21. Departmental Usage Summary

  22. 2009 Departmental Usage Chart

  23. Where Is The Water Coming From?

  24. Where Is The Water Going?

  25. 2009 Water Balance

  26. Maintaining Water Balance- • There Is Significant Value In Ongoing Monitoring of Purchased Water Volume, Internal Usage and Discharge Water Volume. • Meter Data Can Be Integrated Into The Building Management System • A Comprehensive Plan For Meter Locations, Data Acquisition and Analysis Can Be Implemented by Danco/GWS.

  27. Potential Water Conservation and Cost Reduction Projects

  28. Operational Improvements - • Resolve issues with RO Pretreatment – Softeners and Carbon Filters • Improve RO System Operation • Segregate Soft Water System from RO • Reclaim Regeneration Water From Water Softener and Carbon Filters

  29. More Operational Improvements • Additional RO Water Available for HDM • Heat RO Feedwater • Add Controls to Cooling Water Processes (Air Compressors) • Modify Water Main Configuration to Improve Flow & Pressure.
