Water Balance Study Water Treatment, Management and Conservation Solutions
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
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.
Resources Significant Information and Data are required to execute study • Introduction, Site Overview, Site Specific Details • Purchased & Discharge Water Data
Resources Departmental Interviews • HDM – • LDD – • HVAC – • Sytech – • Wastewater Treatment – • LDD Tech Center – • Emissions Solutions –
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
Water Supply & Discharge • An Overview Of Water Sources and Discharge Points.
Water Sources • There are nine (9) water meters being monitored by the city. They are designated as follows:
Discharge Locations • There are seven (8) discharge points. They are designated as follows:
Water Usage History The following graph depicts the increasing volumes of incoming water and discharge water since 2005
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.
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.
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
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.
