As part of measures to conserve the water environment of Lake Biwa, installation of sewerage systems, rural community sewerage systems, combined septic tanks and other domestic wastewater treatment facilities have been advanced especially rapidly. Regarding sewerage systems, in particular, phosphorus content and nitrogen content, which cause eutrophication, are removed by advanced treatment at all sewage treatment plants in Shiga Prefecture, contributing significantly to reducing water pollution by domestic waste water.
At the four Shiga prefectural sewage treatment plants, particularly, world-class level sewage treatment is achieved by a mix of advanced treatment, sludge treatment, and energy-saving facilities introduced in cooperation with national and other research institutes, companies, and other organizations. Through sewage treatment plant operations up to now, advanced experience and technologies have been accumulated by the Shiga prefectural government and sewage-related companies in the prefecture.
Against the background of the accumulated experience and technologies, Ohmi Environmental Plaza was established in April 2013 with the aim of achieving further efficient sewage treatment, handing down the experience and technologies, helping overseas countries with water environment conservation, and revitalizing the local economy by providing support for private companies and others in their water environment business. The plaza provides support for new technology development by joint studies, etc., and offers information for spreading new technologies through various channels and tools.
We provide support for companies and other organizations in developing sewerage treatment-related technologies.
