New  technologies  are  helping  cities  replace  failing  water  infrastructure.  Piping  systems  allow  polymer-based  materials  to  be  inserted  into  old  pipes  to  repair  faults  and    leaks  without  having  to  dig  up  and  lay  new  pipes.
When  it  comes  to  managing  waste  water,  new  systems  are  ,  such  as  Advanced  Immobilised  Cell  Reactor  technology,  which  uses  a  system  based  on  the  immobilisation  of  bacteria,  reducing  the  power  and  land  area  needed  for  conventional  wastewater  treatment  systems.
And  companies  have  realised  that  much  can  be  achieved  by  re-examining  their  products  at  the    stage.  By  designing  items  that  can  be  more  easily  picked  apart  and  that  use  fewer  different  materials  in  their  construction,  companies  can  increase  the  recyclable  content  of  what  they  produce,  cutting  waste  and  generating  cost-savings  by  being  able  to  re-use  parts  and  materials.
