FGC Water Goals

Relative to your baseline, reduce the following by 5% or more annually:

  • Amount of water consumed
  • Amount of stormwater runoff from existing sites

Protecting Resources

Agriculture

Landscaping

  • Use native plants to reduce water and pesticide usage
  • Adjust sprinkler heads to ensure that plants are being watered, not pavement
  • Use drip irrigation instead of conventional watering
  • Water during the early hours or evening to reduce evaporation
  • Install rain or moisture sensors to turn the irrigation systems off when rainfall occurs

Recycled Water

Restrooms/Bathrooms

Stormwater Runoff

  • Meet the Energy Independence and Security Act (EISA) Section 438 requirements for sites undergoing development
  • Reduce existing impervious surfaces and replace with natural landscaping
  • Replace existing impervious surfaces with permeable materials
  • Increase the footprint of on-site green infrastructure systems
  • Capture and use stormwater for non-potable uses
  • Plant trees and other natural vegetation to improve natural hydrologic function of site
  • Use soil amendments to improve infiltration rates of vegetated areas
  • Best practices and case studies can be found at EPA's Green Infrastructure site

Other

  • Sweep parking areas rather than hosing them
  • Install submeters to measure water use by subprocess or specific pieces of equipment
  • Switch from potable to nonpotable water for applications that do not require potable water

Measurement

Recognition

Case Studies (Success Stories)

  • GSA in Chicago saves more than 150,000 gallons of water in one year
  • The U.S. Railroad Retirement Board headquarters in Chicago reduced potable water use nearly 18 percent in one year
  • NASA partners with the City of Sunnyvale, CA to reduce potable water consumption and reuse more water

More case studies are available at the U.S. Department of Energy's Federal Energy Management Program
