Problems of Development of the Water Industry for Providing the Population of Russia with Pure Water
Summary
The water industry is the most important factor in modernization of the economy and development of not only large but also small cities and settlements. The development of housing and communal complex, oriented on the provision of the guaranteed access of the population to potable water of high quality is considered as a task of national significance. The decision of problems of the water industry requires highly qualified staff. Investing in training them is the most important and well paid back part of investments. Russia can and should become one of the world leaders in the sphere of rational water use, application of innovative technologies in practice, the complete provision of the population with pure potable water. For this it is necessary to unite the efforts of the professional community, state and local authorities.

Estimation of the possible use of wastewater thermal energy
for the auxiliaries of the treatment facilities
Summary
Through the example of the wastewater treatment facilities of Mayachnyi village in the urban district of Kumertau (Republic of Bashkortostan), the possibility of using the thermal energy of effluent to heat incoming wastewater in order to enhance the biological treatment process, as well as for heating buildings, is studied. A heat recovery scheme with the transfer of thermal energy for heating wastewater in a surge tank using a surface heater «jacket» mounted inside the tank of the pipe register or in a heat exchanger «pipe-in-pipe» installed downstream the tank is considered. The required heat output of the heat pump unit has been determined, and the design parameters of various heat exchange units have been calculated. The technical limitations that complicate using a «pipe-in-pipe» heat exchanger and pipe registers have been identified. The possibility of heating incoming wastewater to 18–25 °C has been demonstrated.

Management of Process of Construction and Reconstruction of Water Supply-Sewerage Services Objects
Summary
The article states basic principles of the EcopolymerGroup’s concept of management of the process of construction and reconstruction of water supply and water disposal objects and also features of designs of treatment facilities requiring the essentially new managerial approach. Examples of reconstruction and retechnologization of treatment facilities of Novocheboksarsk, Gorodets and Aznakaevo cities are presented. Mandatory requirements for the companies working in accordance with the Ecopolymer concept are expounded. The main thesis when working with a customer is a partnership based on trust. The EcopolymerCroup of Companies being a general designer, contractor, equipment manufacturer and supplier simultaneously assumes the responsibility for results of realization of construction and reconstruction.

Efficiency of Natural Water Disinfection in the Course of Coagulation Treatment
Summary
Results of experimental and theoretical studies of the coagulation treatment of the Don water and monitoring of the concomitant process of its disinfection are presented. The mechanism of separation of algae, bacteria and viruses from water due to their sorption on aluminium hydroxide generated in the course of coagulation is described. The best effect of water disinfection observed during electrocoagulation is 93,8%. The use of this method makes it possible to abandon the primary water disinfection with chlorine, exclude a large-size reagent services and improve the ecological situation in connection with reduction of the volume of the generated sludge (waste of coagulation process).
