Assessment of the hydraulic efficiency of pipeline operation -a new scientific direction in the field of water supply and sanitation

The paper aims to develop and justify a new scientific approach to assessing the hydraulic efficiency of the operation of water supply and sanitation networks with internal deposits. The hydraulic evaluation principle is used as a method for evaluating the hydraulic efficiency of pipeline operation. It is a new scientific direction in terms of the values of the characteristics of the hydraulic potential of pipes which vary depending on the thickness of the layer of internal deposits in comparison with new pipes. The paper proposes a new scientific direction in the field of operation of water supply and sanitation networks with internal deposits - the assessment of the hydraulic efficiency of pipeline operation by the value of the calculated coefficient of efficiency of their operation, determined by special tables that allow setting the period of residual operation of water supply and sanitation pipelines. The values of the coefficient of hydraulic efficiency of operation of water supply and sanitation pipelines with different thickness of the sediment layer have been developed in tabular form. As a result, the paper makes a forecast about the continuation of further operation, or the need for hydrodynamic cleaning of the network from internal deposits.
