The water supply of Yekaterinburg is the process of ensuring the uninterrupted supply of benign water from the source to the consumer in the quantity necessary for the operation of the Yekaterinburg agglomeration .
Water supply in Yekaterinburg is a complex complex of engineering structures and processes, conventionally divided into three components:
- Raw water intake from water sources and transportation to water treatment plants;
- Water preparation in accordance with sanitary rules and regulations;
- Transportation of drinking water to consumers in residential buildings, to enterprises of the city and sources of heat supply and ensuring the needs of fire extinguishing the city

Sources of water supply and hydraulic structures
The main source of water supply in Yekaterinburg is the hydrotechnical cascade of the Upper Makarovsky and Volchikhinsky reservoirs on the Chusovaya River . Additional sources are the Revdinskoe, Novomariinskoe reservoirs on the Revda river and the Nyazepetrovsk reservoir on the Ufa river with a cascade of pumping pumping stations. A backup source in the event of an emergency is the Upper Iset reservoir on the Iset River .
Waterworks are designed to accumulate, regulate and supply the source water at the water treatment plant, as well as to combat the destructive actions of the water element. The structure of hydraulic structures, providing water supply in Yekaterinburg, includes:
- Dams on the reservoirs: Nyazepetrovskoe, Verkhne-Makarovskoe, Volchikhinskoe, Revdinskoe, Novomariinskoe;
- External water transfer paths: from the Nyazepetrovsky reservoir to the basin of the r. Chusovaya , from Revdinsky to the Volchikhinsky reservoir ;
- The water supply path from the Volchikhinsky reservoir to water treatment filtration stations (from fish protection structures along the gravity channel to gateway regulator No. 3, then along the water lines to feed the source water to the Western filtration station and the Headworks of the water supply system, as well as to the heat supply source of the city - Sredneuralskaya GRES ).
The water intake on the Volchikhinsky reservoir is located 30 km from Ekaterinburg on the right bank. The general structure of the water supply path from the Volchikhinsky reservoir to the filtration stations for water treatment is shown in the figure.

Water Treatment
Filtering stations perform a barrier role in the purification of raw water from natural and man-made pollution and are the main guarantor of the supply of safe drinking water in all respects with the relevant SanPiN biological, chemical and organoleptic indicators. Currently, there are 3 large filter stations and 2 small water treatment stations in the city:
- Western filtering station (current maximum capacity for clean water - 455 thousand m 3 / day.)
- Main water supply facilities (current maximum capacity for clean water - 120 thousand m 3 / day.)
- Filtering Sorting Station (current maximum capacity for clean water - 40 thousand m 3 / day.)
- Water treatment station in Severka with a capacity of 1.2 thousand m 3 / day.
- Water treatment station in Isoplit, with the productivity of 0.6 thousand m 3 / day.
As part of the implementation of the Investment Program “Development of Water Supply and Wastewater Systems of the Ekaterinburg Municipal Unitary Enterprise of Water and Sewage Facilities (MUE Vodokanal) for 2007–2020,” it is planned to upgrade existing filtering stations with the introduction of new technologies and increase in productivity.
Conveying water to the consumer
Yekaterinburg water supply networks are a complex engineering system, including: water lines - 31%, street networks - 42%; house entries - 27%. After filtering stations along main water lines, drinking water is distributed to districts of the city, where it is supplied to consumers through pumping stations III and IV lifts through quarterly and street pipelines. In the city of Yekaterinburg there are 2 types of water supply systems:
- Centralized water supply system (powered by filtering stations). Water from the Western Filtration Station and the Headworks of the water supply system first enters the lower zone of the water supply, from where analysis takes place in the upper zones of levels I and II using pumping stations of the third lift.
- Autonomous water supply systems (powered by underground water sources).
In total, the balance of MUE Vodokanal is 1,653.9 km (of which over 114 km are water supply routes) of water supply networks, of which about 70% are cast-iron pipes, 26% are steel, 3% are pipes from polymeric materials, 1% - Other materials. The city’s water supply networks have installed:
- chambers and wells - 23,000;
- valves - more than 60,000 (including pumping stations IV lift and water metering units);
- fire hydrants - 6,500 pcs. (including on the balance of MUP "Vodokanal" - 4 548 pcs.);
- water booths - over 600 pcs .;
- 3-4 lift stations - over 280;
- artesian wells - over 50 pcs .;
- water towers - over 15 pcs.
The economic management of MUE Vodokanal also has water supply networks and facilities located in remote suburban settlements. Water supply of settlements is carried out from underground water intakes (artesian wells). Basically, there are two schematic diagrams of water supply from the well to consumers: water from wells is pumped into submersible pipelines through which it is transported to a clean water tank (RFU) at a pumping station of the 2nd lift, then pumping units are supplied to the village, or water from wells pipelines enters the water tower (VNB) and flows by gravity directly to consumers. The exception is the residential area of Isoplit , the housing stock, enterprises and social facilities of which are supplied with water from the lake. Scratch pump filter station.
