An approach to complex accounting of hydraulic and aerodynamic parameters of a gravity sewage pipeline for the purpose of solution of its designing and effective operation problems has been presented herein. Consideration has been made of the variants which provide the subsurface space ventilation of a gravity pipeline in presence of aggressive and fetidly smelling gases by a mechanical air exchange system. Taking into account the complexity of manual processing of mathematical dependencies that describe the operation of a gravity pipeline and the processes that take place in it, the implementation of the problem has been achieved by developing and applying a special automated calculation program. At the corresponding values of air exchange, the dynamics of harmful gaseous substances released into the subsurface space of the gravity pipeline per unit of time, as well as the duration of their removal to the maximum permissible concentrations in the surrounding air space of populated areas, have been revealed.
