Method for processing in-process monitoring results to improve drinking water quality and safety (experience of SUE «Vodokanal of St. Petersburg»)

Summary

The paper concentrates on the experience of SUE «Vodokanal of St. Petersburg» with regard to the development and introduction of the method of processing and storing the data of in-process monitoring drinking water quality and safety. In accordance with Russian Government Resolution No. 10 of January 6, 2015, water utility operators are responsible for conducting in-process quality control of drinking water at the source, after water treatment, and in the water distribution network. SUE «Vodokanal of St. Petersburg» provides for the in-process water quality control at 396 monitoring points. Considering the requirements of the Russian legislation, the amount of laboratory tests is approximately 16,000 per month. Processing and analyzing such a volume of information received monthly is a labor-intensive and resource-consuming process. Automating the process of processing laboratory test results provides for reducing the human factor effect in data transfer and processing; automatic checking deviations from acceptable limits, and minimizing errors in calculations and result interpretation.

Development of a national standard in the field of automatic water quality control for water supply and wastewater disposal systems

Summary

Lately a lot of attention has been paid to the aspects of the automation of analytical monitoring of the composition and properties of different water types, on the legislative level, in particular. Formation of risk-oriented approaches for drinking water supply; requirements to analytical wastewater monitoring systems as part of the transition to the best available technologies – all this makes actual the issues of developing and using automatic water quality monitoring systems. Such measuring systems provide for not only real-time control of the technological processes of water and wastewater treatment, but also for executing industrial environmental control of effluent discharges, monitoring of pollution of natural waters, and drinking water quality monitoring. The main tools that underlie the development of a state standard for analytical water quality monitoring systems are presented.
