FY 2011 Industrial Wastewater Utilization and Treatment Facility Refurbishment and Upgrade

(Groundwater Reuse Project)

Ken Kono, Project ManagerNASA Ames Research CenterMarch 11, 2010

UTILIZE AVAILABLE GROUNDWATER DISCHARGES TO MEET ALL INDUSTRIAL WATER NEEDS OF

NASA AMES ARC JET COMPLEX AND UNITARY PLAN WIND TUNNELS

PROJECT GOAL

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

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

PRELIMINARY ENGINEERING PHASE

• ASSESS WATER QUALITY AND QUANTITY

• ASSESS EXISTING SOURCE INFRASTRUCTURE

• DEFINE NPDES REQUIREMENTS
