Sewage Systems in Small Settlements

The systems of small settlements include networks and facilities designed for drainage and treatment of domestic and close to it industrial wastewater in an amount up to 1400 m³/day. A small settlement is a place with a population of up to 5000 people. At present, attempts are made to stop the process of degradation of sewage treatment plants in small settlements, which have exhausted their resources and require modernization. Sewerage of small settlements is provided for by an incomplete separate system. It is recommended to use a centralized sewerage scheme for one or more settlements, separate groups of buildings and industrial zones. The choice of a method for treating small amounts of wastewater, a complex of treatment facilities, their types and designs largely depends on local conditions: the possibility of allocating land for treatment facilities, the distance of this area from housing, the topography of the area, soil, hydrological and climatic conditions, the nature and the location of the reservoir into which purified water can be discharged.
