Reasons For Wastewater Reuse• To comply with BPCA Residential Environmental Guidelines
• To satisfy LEEDTM
Water Efficiency Credits
• To fulfill NYCDEP Comprehensive Water Reuse Program requirements to gain 25% reduction in water & sewer rates
• High density of units helped to minimize extra plumbing costs
5
Wastewater System Features
• Membrane Bioreactor System
• Ozone system for color removal
• Activated carbon odor control system
• Multiple barrier approach for disinfection
- Membranes have an effective pore size of approximately 0.4 micron
- Ozone is a powerful oxidant
- UV system follows ozone

Wastewater System Features- continued
• Continuous circulation of water storage tank contents through ozone and UV systems
• Automatic potable water fill valves at water storage tanks to ensure uninterrupted supply of flush water
