The Federal Energy Management Program (FEMP) has developed a variety of technical resources and tools focused on alternative water.
These resources aim to provide federal agencies with crucial technical information on alternative water systems, facilitating strategic planning for their implementation. Alternative water refers to water sourced from sustainable supplies, serving to mitigate the reliance on fresh surface water and groundwater.
There are a variety of alternative water sources, including:
- Harvested rainwater
- Captured condensate from air handling units
- Reclaimed wastewater
- Process reuse
- Desalinated water
The applications of alternative water range from irrigation to vehicle wash and cooling tower makeup.
