FY 2011 Industrial Wastewater Utilization and Treatment Facility Refurbishment and Upgrade

  1. 1. FY 2011 Industrial Wastewater Utilization and Treatment Facility Refurbishment and Upgrade (Groundwater Reuse Project) Ken Kono, Project Manager NASA Ames Research Center March 11, 2010
  2. 2. PROJECT GOAL UTILIZE AVAILABLE GROUNDWATER DISCHARGES TO MEET ALL INDUSTRIAL WATER NEEDS OF NASA AMES ARC JET COMPLEX AND UNITARY PLAN WIND TUNNELS
  3. 3. ARC JET COMPLEX UTILIZES 110,000 GALLONS PER DAY* OF POTABLE WATER TO OPERATE THE STEAM VACUUM SYSTEM *OPERATING DAY, APPROX. 170 OPERATING DAYS/YEAR
  4. 4. UNITARY PLAN WIND TUNNELS UTILIZES 60,000 GALLONS PER DAY* OF POTABLE WATER TO MEET FACILITY COOLING REQUIREMENTS *OPERATING DAY, APPROX. 170 OPERATING DAYS/YEAR
  5. 5. ACTIVE PUMP AND TREAT FACILITIES AT AMES NASA RGRP Sept. 2001 WATS Nov. 1998 MEW N.101 Oct. 1998
  6. 6. PRELIMINARY ENGINEERING PHASE • ASSESS WATER QUALITY AND QUANTITY • ASSESS EXISTING SOURCE INFRASTRUCTURE • DEFINE NPDES REQUIREMENTS
  7. 7. IN SITU SDI (SILT DENSITY INDEX) TESTING AT TREATMENT FACILITIES
  8. 8. CURRENT DISCHARGE RATE FACILITY AVERAGE FLOW DESTINATION REMARKS (gallons per day) N 101 (MEW) 179,000 STEVENS CREEK VIA 6” DIA. PIPE, PARTIAL RE-USE AT N271 NASA RGRP 22,000 STEVENS CREEK JOINS N 101 PIPE WATS 95,000 STORM WATER VIA STORM WATER RETENTION BASIN CONVEYANCE SYSTEM TOTAL FLOW = 296,000 GALLONS PER DAY OR OVER 108 MILLION GALLONS PER YEAR IS AVAILABLE FOR RE-USE CURRENTLY, LESS THAN 10% IS RE-USED
  9. 9. DAILY PEAK DEMAND WATER FLOW DIAGRAM 53,000 GAL 296,000 GAL UNUSED GROUNDWATER 126,000 GAL CONSOLIDATED COMBINED DISCHARGE TO GROUNDWATER STEVENS CREEK 243,000 GAL R.O. FACILITY 73,000 GAL 170,000 GAL CONCENTRATE PERMEATE 0.85 MG PERMEATE STORAGE 110,000 GAL 60,000 GAL ARC JET UNITARY PLAN COMPLEX WIND TUNNELS
  10. 10. ANNUAL WATER FLOW DIAGRAM (MG = MILLION GALLONS) 66 MG 108 MG UNUSED GROUNDWATER 79 MG CONSOLIDATED COMBINED DISCHARGE TO GROUNDWATER STEVENS CREEK 42 MG R.O. FACILITY 13 MG 29 MG CONCENTRATE PERMEATE 0.85 MG PERMEATE STORAGE 10 MG 19 MG ARC JET UNITARY PLAN COMPLEX WIND TUNNELS
  11. 11. EXISTING DISCHARGE AND DISTRIBUTION FLOW DIRECTION
  12. 12. ASSESS EXISTING TREATMENT FACILITY 2002 - 2006 EXISTING REVERSE OSMOSIS VESSELS CONSERVED APPROXIMATELY 7 MGAL/YEAR OF POTABLE WATER
  13. 13. MODEL EXISTING AND PROPOSED PIPING SYSTEM
  14. 14. WORK WITH THE STATE WATERBOARD • NOTIFY THE BOARD OF NASA’S INTENT • SUBMIT APPLICATION FOR NPDES PERMIT
  15. 15. PROJECT SCHEDULE •PRELIMINARY ENGINEERING SEPT 2009 – MAR 2010 •FINAL DESIGN APRIL 2010 – OCT 2010 •CONSTRUCTION FEB 2011 – OCT 2011
  16. 16. QUESTIONS?
