GREYWATER AND STORMWATER REUSE

eDesign Dynamics collaborated with Nastasi Architects to design a greywater recycling system that would reduce the wastewater stream "footprint" significantly when compared with standard building designs.

Our preliminary design for a rainwater harvesting system called for collection of rain from the roof to be stored in a retention/detention tank located in the basement of the building. Greywater from showers, bathroom sinks, clothes washing machines, and dishwashers would be captured through a separate waste line network and combined with the stored rainwater. Treatment of this water would be accomplished using a physical filtration and a disinfection unit that complies with state and local regulatory requirements.

Water conservation and reduction of the waste stream through re-use on the building scale is a crucial step in easing the burden on sewers and treatment plants. Through these measures Combined Sewer Overflow events (CSOs) can be reduced in frequency and volume. The risk from flooding of municipal and personal property during storm events can be decreased. Benefits of wastewater reduction designs eliminate the need for costly end-of-the-pipe solutions such as underground storage tanks and wastewater plant re-designs.
