The problems connected to propagation of a gravitational field are considered. The law of electromagnetic radiation frequency change in gravitational field is shown. The problem of a gravitational field quantization is investigated. Energy of a graviton is found by two ways. First, on the basis of use quantum gravitational eikonal and Lagrangian of a gravitational field the energy of a solitary graviton is found. It is shown that graviton has the mass proportional to its frequency. Second, due to refusal from symmetric stresses tensor in structure of an energy-impulse tensor the quantum form of the energy-impulse tensor in Einstein's equation is found. It has allowed found the energy of a solitary graviton. Both ways of an energy graviton finding has given the identical result. It is shown that the solution of the Einsteins equation with use of the quantum form of an energy-impulse tensor for the certain direction represents the sum of a gravitational wave and a graviton. It is found out that at approach of a graviton to the massive bodies (double stars) radiating gravitational waves there is a resonant pumping of the gravitational field energy of these bodies to the gravitons with increase in their mass and frequency. It enables registration of the gravitons with the help of the detector located near to massive bodies. The assumption is made that dark energy of a gravitational field is all set of the graviton energies of a space.

The activity of housing services and utilities results in great amounts of waste: sludge of water and wastewater utilities, waste waters of TPPs and recycling water supply. The known ways of such waste utilization are related to production of construction materials and secondary reactants for wastewater treatment. Though the volumes of sludge most often exceed the regional demand in raw materials for local construction materials or coagulants. Moreover sludge as man-made raw material cannot compete with their natural analogues in terms of quality.The basic characteristics of housing and communal services sludge storages were considered from the perspective of their target development. The system of state assessment of sludge storages was represented by the multidimensional data analysis. The waste disposal facilities considered in this study were classified into three groups from the perspective of the feasibility and practicability of their abandoning. An example of the digital matrix of waste disposal facilities’ condition was given. The constructive and technological design of the system of recultivating materials production was given.
