Beijing is planning to pipe in desalinated water from the port of Caofeidian in Hebei province to meet increased demand.

Under the desalination project, 1 million metric tons of drinking water a day will be produced from nearby Bohai Bay.

Supplies will be piped to Beijing, and are expected to satisfy one-third of demand in 2019. Caofeidian is under the city of Tangshan's jurisdiction.
