Summary

One of the ways of enhancement of energy efficiency of pumping plants at water supply and wastewater disposal systems introduced successfully at the Municipal Unitary Enterprise Gorvodokanal of Novosibirsk is considered. The matter is the introduction of high-voltage stations of frequency control of pump units with power voltage of 6–10 kV. Variants of frequency regulation and experience in their introduction at pumping stations are presented.
