US Water Infrastructure to be Upgraded

US EPA has announced a new national policy to deal with its aging water infrastructure.  The policy intends to upgrade systems using a range of sustainable options that will be able to deal with the potential storm water issues caused by climate change as well replacing aging systems. Link New York alone has  12,000 km of sewer most now fairly old and either overloaded or in need of replacement. Recently a plan was unveiled to spent $1.5 billion on upgrading their sewerage system to reduce CSOs dumping in excess of 110 billion litres of contaminated water each year into New York surface waters. This upgrade will include a range of sustainable urban drainage options from  green roofs to porous pavements to reduce the volume of surface water going to sewer.
