The study is focused on reviewing about suitability evaluation of collection of small scale sewage treatment, and solve their problem. It is that as collection method, collect tank of gathering sewage is conducted and sewage is carried to around sewage treatment facility or collect pipe using collect carts periodically. Collect treatment project has application to some areas as like park, an amusement park and playground which produces sewage occasionally. The object of primary collect study is the upper stream of water resource, national park and purity region urgently. But, as a result of a spot inspection, we were selected 4 sites, Ju-Cheon, Bu-Gi, Bu-Nam and Sung-Su region that these places are unable to establish small sewage facilities. Evaluation was conducted with construction cost of facilities and collect pipe, maintenance cost. Comparison with sewage treatment facility, collect treatment project proper small sewage. It is suggested that its capacity of small sewage facility is under 100ton/day, collect distance is under 25~30km. It is suggested that collection for small scale sewage treatment has an adapt possibility not only Yong-Dam dam region but also other regions. Also, in order to carry out collection for small scale sewage, it is need that a legal basis.

According to the more the sewage facility is getting enlarged the more the demand for sewage improvement is increased to get ready improved the method after recognizing the problems and operating states of sewage facility in progress in ChonBuk Province. Therefore this study focused on surveying current status of systems and proposing proper guidelines with alternatives for the improvement of existing systems. The results and alternatives to improve the current conditions and problems of small scale sewage treatment facilities operating now are summarized as follows: The current installation status of the small sacle sewage treatment system showed that 207 treatment plant have been built before May.2003. The high efficiency sewage combination purification tank (KDHSTprocess) is applied to the largest number of treatment plant, which is the 27% among total plant, and the soil trench, nightsoil and high organic concentration treatment methods, activated sludge are surveyed to be 19%, 16%, 13%, respectively. Among these processes, application rate of the contact aeration rate of the contact aeration process is being increased but the soil trench process is not being applied any more due to various problems. The bio-membrane methode apply to enlarge the efficient treatment after improving the fixation of sticking microorganism and accumulation technique by using the media. It`s expected to utilize the manless automatical operation and remote control technique even if sewerage facility in the village give them disgusted. From now on, It will be good to change to the environmental friendly facility. High-tech technique is needed with removing the nitrogen, phosphorus in order to satisfy the standard for the treatment rate and the quality of water.
