High processing

We remodel 1 system into high processing facility among serieses of 3 in April, 2004, and we perform altitude processing (the AO method) for the purpose of the phosphorus removal, and our center discharges about half of processing quantity of water into weasel river.

Use of upper part of facility

Because our center is next to residential area and station, it is designed so that the noise and odor do not go out by installing processing facility underground. We establish use of citizen facility (park, open space) who the upper part considers harmony with surrounding environment, and gave tree planting.

We use limited land effectively

Large land is necessary, but we install management ridge or electricity, machine room on the processing facility and deepen deposition place and the depth of the water of reaction tank first and use limited land effectively to process drainage.
