Summary Though wastewater treated population rate in Japan has reached 85.7% (at the end of fiscal year 2009), construction of sewage facilities is considered still important. For efficient construction of wastewater treatment facilities, we researched characteristics of some kinds of wastewater treatment facilities such as effluent quality, maintenance cost, and so on. And we extracted indicators for assessment and analysis about wastewater treatment facilities.
