Abstract:
Reports on the status and treatment of wastewater, in smaller settlements, in Republic of Srpska are discouraging. The current situation is the result of inadequate activities of local governments, which usually do not have adequate professional staff and other conditions for managing such investment activities. In such a situation, local governments do not accept the offered technologies and processes for municipal wastewater treatment, which often do not correspond to specific conditions in the field. In the paper are elaborated methods of wastewater treatment of smaller settlements with unconventional technologies. Seven representatives of unconventional technologies are described: septic tanks, Imhoff`s sedimentation tank, lagoons, artificial swamp sistem of purification with oil, green filters of moss and processes with biofilm. Some of the technologies are described in more detail. An example of the application of unconventional technologies is given - the design of wastewater treatment plants for a small settlement. For each of these devices, are given retrospective view for operating and maintaining as wll as advantages and disadvantages which they possess. The paper points to some important elements that are important for the beginning and managing of investment activities related to the preparation, design, construction and maintenance of wastewater treatment plants of smaller settlements
