PRESSURE AND WITHOUT PRESSURE MOTION OF FLOWS IN SEWAGE SYSTEM WITH CIRCULAR STRUCTURE Summary. In the article the questions design of motion of flows are considered in the systems of the sewage system with a circular structure. Such systems take place at a reconstruction and development of the sewage system. Sizes of charges of flows which are distributed on separate girdling collectors, it is suggested to determine on the basis of decision of equalizations of maintenance of mass and energy. In the article resulted equalization for the different cases of flows motion in the sewage system. The examples of calculations of all these cases are also given. The method of determination of calculation charges is presented in the circular systems of the sewage system. The examples of calculations are resulted on this method. Key words: sewage system, collector, flows, pressure and without pressure mode, ring network, calculation pressure.
