In the nearest future, water consumption rate is to be reduced to 160 litres per person per day in Moscow. Water consumption reduction can cause reduction of the water flow velocity, deterioration of organoleptic properties of the water and cause flavours, odours, turbidity and colourity. The solution may consist in the narrowing of the network diameter, especially in those sections that need urgent renovation, including trenchless renovation. It will accelerate the flow velocity and ensure pre-set sanitary and hygienic properties of the water. However, narrower diameters can affect fire water flows that constitute the subject matter of this research.The authors provide the research findings based on the automated hydraulic, technical and economic analysis of loop water supply systems performed through the employment of alternative renovation methods, modeling of a water supply network on the basis of existing diameters and on the basis of diameters reduced by grades 1 and 2. It is proven that water consumption reduction accompanied by the pipeline diameter reduction by one grade doesn’t cause deterioration of any hydraulic properties; rather, itaccelerates the water flow velocity and doesn’t cause any failure to comply with effective water supply norms applicable to fire extinguishing.The authors present their original method of identification of the optimal option for trenchless renovation of pipelines and their analysis of annual energy savings.

Operation of present-day water supply networks and management of hydraulic models of pipeline networks are labour intensive and ambiguous tasks requiring a sophisticated approach. Operation of water supply networks servicing major Russian cities is accompanied by processing of extensive amounts of information; moreover, some elements of the water supply infrastructure are hidden under the ground. Nowadays operators of water supply networks take advantage of the advanced software used to solve a wide range of tasks associated with data filing, overall evaluation, analysis and optimization of the most important parameters of urban water supply networks. The above software is an essential tool in the management of water networks in major cities. Their ability to collect and process all data on water supply networks and to conduct some research aimed at the improvement of various parameters of the system, including optimization of hydraulic characteristics of the pipeline is employed by researchers and water pipeline operators.The authors analyze and compare CAD software systems designated for water supply networks servicing big cities, capable of resolving multi-component problems and ensuring the reliability of water supply systems.
