Summary Though wastewater treated population rate in Japan has reached about 87% (at the end of fiscal year 2010), construction of sewage facilities is considered still important. For efficient construction of wastewater treatment facilities, we researched an estimate method for water qualities of sewage treatment facilities of municipalities and actual states of connection to sewers of municipalities.
