Many local governments operate sewerage services under severe financial hardship. They need to develop, more efficiently, new facilities for regions left without sewerage and that supplement the capacity of existing equipment in urban areas. JIWET has been working on the effective development and maintenance of sewerage via joint research with the aim of realizing a more comfortable, vigorous life.
Joint research already conducted
「Cooperative research on monitoring system of manhole pump operation」、「Cooperative research on save area system of shield construction departure shaft lot」「Research on the shield tunnel lining with the FRPM Pipe」、「Research on the standardization of spiral guideway style drop shaft」、「Investigation research on steep gradient sewerage pipe」
etc.
Recent research
「Study on the Project for the Quick Elimination ofSewer Unavailability」
etc.
