Khorenzhaia I. Justification of environmentally sound waste water disposal from residential areas

There was offered a new scientific approach to the development of existing technologies and control of both waste water and drainage water disposal from residential areas (RA) to ensure the environmental safety of groundwater, according to which: there was justified the common procedure for removal of drainage water and waste water according to different schemes of their disposal; the existing schemes of disposal systems of RA are supplied with a control module for managing of waste water and drainage water supply to the treatment plants located in RA in both ordinary and emergency situations, and there was also developed a mathematical model for choosing of operational parameters of this module; the expediency of cleaning of drainage water as well as surface waste water mainly at bioengineering treatment plants is grounded; it was proposed to eliminate the existing organizational inconsistency concerning the operation of different drainage networks; there was developed a method of assessment of the ecological and social impact as a result of implementation of proposals as for creation of an ecologically safe system of waste water and drainage water disposal from the territory of coastal RA. Key words: wastewater, domestic and industrial waste water, surface waste water, drainage water, accidents at water disposal systems, bioengineering treatment plants, environmental safety of surface water bodies.
