Case Studies: Ecologically-Based Water Treatment Solutions

“Living  Machine  came  to  our  aGen&on  for  its  ability  to  provide  onsite  wastewater  treatment    and  allow  the  project  to  pursue  a  reduced  water  footprint  –  mee&ng  the  Port’s  water  and  LEED  goals.”  

“located  the  Living  Machine  in  the  entry  lobby  crea&ng  a  welcoming  feature  to  the  new  offices  and  showcasing  the  Port’s  commitment  to  the  community.  For  visitors  it  is  a  surprise  to  learn  that  they  are  walking  past  a  wastewater  treatment  system.”  

“Port’s  new  headquarters  office  building  has    been  selected  by  several  organiza&ons  including  being  named  one  of  the  10    Greenest  Buildings  by  Forbes  Magazine”
