Novosibirsk MUP GORVODOKANAL

Gorvodokanal (waterworks of Novosibirsk) is the third-largest water utility in Russia (after Moscow’s and St. Petersburg’s). The company supplies drinking water to Novosibirsk and its satellite cities, including Ob, the science city of Koltsovo, Krasnoobsk, and other nearby settlements within the Novosibirsk agglomeration, serving a total population of approximately 2 million people.

The Ob River is classified as a second-class hazard in terms of microbiological indicators. To ensure the quality and safety of drinking water, a multi-barrier system design was chosen. In this system, ultraviolet disinfection serves as the primary barrier, while chlorination provides prolonged protection within the pipeline. The UV disinfection stage was to be applied at different stages of water treatment depending on the technological schemes of Pumping-Filtration Stations (PFS-1 and PFS-5).

At PFS-1, the UV disinfection block was launched in 2010. It consists of four operational and one backup packaged units from the VOLTA group. These UV units are located after clean water reservoirs at the water treatment facilities. Water that has undergone mixing, sedimentation in horizontal clarifiers, and rapid filtration is fed into these reservoirs and then pumped into the city through a second-stage pumping station.

The UV disinfection complex at PFS-5 was commissioned in 2013. Here, the UV station, consisting of four operational VOLTA units, is located at the head of the facilities on the pressure pipeline of the first-stage pumping station before the mixers.

The UV installations ensure reliable disinfection in compliance with SanPiN 1.2.3685-21 requirements. The total design capacity of both stations is 950,000 m³/day.
