The research project covers the area normally referred to as the Noubi Plain. However, the research is mainly concerned with the low-lying lands which comprise mostly of sedimentation deposits of alluvium soils of the Kiso, Nagara and Ibi rivers.The intrusion of residential and industrial activities into these low-lying areas have created water quality problems.The objection of this research is to study the effect of the introduction of a waste water treatment plant in the lower basin of this area in order to solve these water quality problems.For the purpose of this research the Takasu Polder was selected as the specific project area.Several data were colected from different locations within this area for study and analysis. The pollutant load around Hirata Town was found to be very high. However, four waste water treatment plants under construction in Hirata Town to tackle this problem are expected to take more than four years to complete.The studies showed that out of ever many treatment plants covered only a few performed to a reasonable level of standard. However, it is important to note that all these plants can produce high quality effluent if the management competence of the staffs and companies in charge of these plants are improved, and the plants are kept running continuously without stoppages.

该研究项目涵盖通常被称为努比平原的地区。然而，研究主要涉及主要由木曾冲积土沉积物组成的低洼地，住宅和工业活动侵入这些低-本研究的目的是研究在该地区的下游流域引入污水处理厂的效果，以解决这些问题。本研究以高须圩田为研究对象，收集了该地区不同地点的水质数据，并进行分析研究。平田町周围的污染物负荷被发现非常高。然而，为了解决这一问题，平田町正在建设的4座污水处理厂预计需要4年多的时间才能完工。研究表明，在众多的污水处理厂中，只有少数达到了合理的标准。然而，重要的是要注意，如果负责这些工厂的员工和公司的管理能力得到提高，并且工厂保持连续运行而不停机，所有这些工厂都可以产生高质量的污水。
