World Usability Day - Graywater Recycling
SD-HFES participated in World Usability Day by promoting the recycling of graywater, which was profiled on the HFES website. SD-HFES also participated in San Diego EarthFair 2010 at Balboa Park. We had great success in educating and spreading awareness of conserving and recycling our water resources.
Graywater is wastewater generated from laundry and bathing/showering, but NOT from the toilet. Comprising of 50-80% of residential wastewater, graywater gets its name from its cloudy appearance and is neither fresh (white, or potable, water) nor heavily polluted (black, or sewage, water). Water recycling is accomplished by harvesting the graywater from your home and then using the water on your lawn or in your garden - see image below.
Graywater - How It Works
The use of graywater has considerable financial savings and many environmental benefits as well. An overview of graywater and why it is attractive can be found in this printable Graywater Recycling brochure (PowerPoint). Click here for a free PowerPoint viewer.
