Presentation to Moffett Restoration Advisory Board: FY 2011 Industrial Wastewater Utilization and Treatment Facility Refurbishment and Upgrade (Groundwater Reuse Project) Ken Kono, Project Manager, NASA Ames Research Center

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. PROJECT GOAL
UTILIZE AVAILABLE GROUNDWATER DISCHARGES TO
MEET ALL INDUSTRIAL WATER NEEDS OF
NASA AMES ARC JET COMPLEX AND UNITARY PLAN
WIND TUNNELS

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. 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. ACTIVE PUMP AND TREAT FACILITIES AT AMES

6. PRELIMINARY ENGINEERING PHASE
• ASSESS WATER QUALITY AND QUANTITY
• ASSESS EXISTING SOURCE INFRASTRUCTURE
• DEFINE NPDES REQUIREMENTS

7. IN SITU SDI (SILT DENSITY INDEX) TESTING AT
TREATMENT FACILITIES
