Kanagawa Wastewater Treatment Plant

　Kanagawa Wastewater Treatment Plant started operation in March 1978 as the seventh water reclamation center in Yokohama.
　Most of the Kanagawa Ward, Nishi Ward and Hodogaya Ward, as well as part of Tsurumi Ward, Asahi Ward and Kohoku Ward, treats about one-seventh of the population of Yokohama.
　Advanced treatment (removal of nitrogen and phosphorus) began in March 1999, and advanced treatment of 80% of fine weather currents.
　In addition, as a countermeasure against pollution runoff in rainy weather, a rainwater reservoir that stores early rainwater has been installed.
