Assessment of Water Saving When Using the Regulated Electric Drive in Pumping Plants of Water Supply Systems


Methods of the assessment of water saving developed by specialists of the Yagorba Ltd. and the automation laboratory of the NII VODGEO PC are described. The assessment of water saving when using a regulated drive for various variants of pumping plants operation in the water supply systems can be made with the help of these methods. Results of the calculation are close sufficiently to the results of operational supervision on real objects. This procedure can be used for estimation of reduction of wastewater disposal into the sewerage owing to the reduction of non-productive discharges in a water delivery system. The example of calculation of predicted water saving for a pump installation with one and several units is presented.
