Greywater–Wastewater produced by bathtubs,
sinks, and washing machines –Low levels of suspended solids and
turbidity–75% of household wastewater is grey–Possible uses
• Car washing• Ornamental fountains/ponds• Irrigation
Examples of Greywater Systems
• Simple– Sink to toilet
• Advanced
Our Design• Residential apartment building• Collect water from
–Washing machines–Rain gutters–Air-conditioning units
• Storage• Irrigation
–Demonstration garden

Rainfall Calculation
• Area of roof * (Avg rainfall in inches / 12 inches per foot)– 6000 sq ft * (52.34 in/yr / 12) = 26,170 ft of
rain/yr
• Rainfall in feet * 7.48 gallons per cubic foot – 26,170 ft * 7.48 = 195,751.6 gallons per year
• Yearly rainfall / 365 days per year– 195,751.6 gallons / 365 = 536.3058 gallons
per day
