Introducing innovative materials and technologies in the water distribution network

Summary

A review of the advanced innovative materials and technologies used in reconstruction and operation of the water distribution network is presented. The basic causes of pipeline failure are considered, the advanced technologies and equipment that contribute to extending the pipeline operational life are described. A comprehensive analysis of the newly developed corrosion-resistive coatings, socket joints is given alongside with the results of retrofitting energy-independent systems of monitoring water distribution network parameters based on multiparameter sensors and remote control of the shutoff and control valves. The experience of MPUE Mosvodokanal in using innovative trenchless technologies of pipeline repair and rehabilitation is systemized.

The causes of odor in drinking water during the summer period in Ekaterinburg

Summary

The results of studies carried out to determine the causes of odor of biological origin in public water supply of Ekaterinburg during the summer period are presented. The analysis was performed with water samples taken in accordance with the operating programs of in-process water quality monitoring in the public water supply systems during the 2001–2013 vegetative periods. The algae species directly inducing the odor in water were determined. The markers that provide for well-timed responding to the water quality changes were determined. Based on the results of the studies the order of actions during the summer period was introduced at the enterprise that provided for measuring the amount of Planktothrix agardhii with the standard procedure of raw water monitoring and reducing the sampling intervals in case of spotting the trends of the algae amount growing. In case the set marker value is reached the process flow pattern at the treatment facilities is changed to ensure guaranteed elimination of water odor.
