The problem of resource saving is particularly relevant for household waste removal systems and sewage networks in modern residential houses. Some options for the shared use of sewage networks and natural organic waste removal systems in residential buildings are assessed by the author. Layouts, operation patterns and elements of the systems are provided. Strengths of shared operation of the systems and networks are analyzed with account for the present-day requirements applicable to the systems in question. The positive factor is that residents do not need to spend money for expensive food waste disposers for their homes. They will also use garbage chutes in their houses.Joint operation of food waste removal systems and domestic sewage networks will reduce the load on landfills which has been increasing in the recent years. It will increase the load on urban sewage networks and water treatment facilities, but it will not be a critical factor, because treatment facilities are capable of purifying water without much difficulty. Processed food waste may be applied to produce fertilizers and biogas to be used as fuel. Therefore, benefits of the limited use of landfills are obvious.Waste shredding is the most convenient, efficient and nature friendly way of processing the organic waste at the initial stage of its generation. It prevents rotting typical for the organic waste if disposed together with the municipal solid waste.The experience of the United States, where food waste is treated by in-sink food erators and removed into the sewage system is less expensive for city budgets than their disposal at landfills.Food wastes consist mainly of the water (70 %); therefore, water treatment facilities assure a more natural way of processing this type of waste than waste collection and disposal. Separation of organic waste from solid waste also reduces the number of disease vectors such as flies, rodents, and cockroaches.

Introduction. The subject of the study is the study of technologies to ensure the reliability of sewage pumping stations (SPS), exploited in the Far North. One of the most important problems is the freezing of water in the SPS tanks, associated with the incorrect selection of the insulation of the SPS of new TPPs, as well as the deterioration of the insulation of the SPS under the influence of aggressive media on the old TPPs. As a solution, the article considers two main methods of internal heating: liquid and electric. Both methods were analyzed using the example of the Yakutsk State District Power Plant-2, where the disruption of the drainage system may lead to a station shutdown. Materials and methods. The purpose of the study was a comparative analysis and selection on the basis of a feasibility study of the most reliable method of heating the pumping unit of the Yakutsk State District Power Plant-2, exposed to low temperatures and, as a consequence, the freezing of wastewater in tanks. On the basis of field surveys and the processing of their results using mathematical statistics, the causes of the problem of water freezing in the SPS units at Yakutsk State District Power Plant-2 were studied and analyzed. Technological characteristics of the installed SPS were also analyzed, heat engineering calculations were performed, economic indicators were calculated, and further solutions to the problem under consideration were determined. Results. Analysis of the technical parameters and configuration of the SPS showed that the installed insulation and the heating system do not correspond to the territorial conditions in which this equipment is installed. To bring the SPS into working condition, two solutions for internal heating of tanks were developed and their comparative analysis was performed. Selected heating option with heating cable. This system has been successfully implemented and is operating normally. Conclusions. The results of the work can be used to repair thermal insulation and install a heating system for industrial pumping stations without using earthworks in the conditions of the Far North and on the territory of permafrost soils.
