Energy efficiency and renewable energy sources have drawn a greater attention by EU, in particular for climate change policies as it can substantially cut down CO2 emissions to meet EU environmental obligations. It is well established that in drinking pipe systems Pressure Reducing Valves (PRV) are used as a mean for excess energy dissipation for the purpose of pressure control. This type of solution can be adopted, as a mitigation method to control the system losses, in particular, the available overload, which must have to be dissipated to avoid leakage or rupture occurrence in the pipe system. The use of micro-hydro systems seems to provide a better approach as a sustainable solution in terms of controlling the system pressure as well as to provide a non-negligible income by producing clean energy. Computational simulations, experimental research and engineering project development are carried out to analyse and compare the hydraulic system behaviour between a PRV and a pump working as a turbine (PT). This research creates an important challenge for seasonal stabilization of the energy supply by using water supply systems, due to the stochastic nature of river-hydro resources.

The energy saving ecological water supply system is proposed. The system can be implemented both in heat power engineering, in particular in circulating water supply systems for industrial enterprises, and in construction industry where there are heat evolutions produced by equipment and due to technological processes. According to the forecasts of Russia's energy strategy, the production of thermal energy will increase by 22-34 % in 2020. At the same time, it is planned to increase the real heat consumption by 1.4-1.5 times due to reduction of losses in the conditions of high energy saving potential in all energy sectors beginning with production to transportation and rational use of energy sources. The system of housing and utilities is extremely energy intensive, since utility infrastructure is worn out up to 80-90 %. The practical lack of biosphere-compatible technologies for engineering systems design and operation in Russia does not allow providing resource-saving at all stages of full life cycle of a building or a structure. Known studies and proposals based on the research and development decisions of RAASN Research Institute of Building Physics mainly relate to the thermal protection of the shell of a building and are not represented by engineering interconnected systems. Therefore, the development and implementation of measures for the integrated development of utility infrastructure becomes topical. The solution of this problem is related to complex of engineering and technical activities, including thermal protection by increasing thermal resistance of enclosing structures of buildings, upgrading heat and water supply systems, using non-traditional energy sources.
