Saving water

Published on Friday, 20 March 2020

According to the UN, 663 million people around the globe have no access to clean potable water and 80% of them live in rural areas.

Russia has second largest water resources in the world, however lots of regions still experience water shortages given its uneven distribution.

Water gives life to everything living on the planet. We all know that water is a renewable source, just like sun and wind. Then why do we experience shortages? Because people need clean water, poison-free and ready-to-be-consumed. The amount of such water constantly decreases.

Here are few interesting facts:

1.       Global fresh water resources are indeed in decline.  Rivers are becoming shallow, while water demand is growing.

2.       For the most part of used water in the world there is no treatment plan, it returns to lakes and rivers unprocessed, hence makes them even dirtier.

3.       One third of the world water resources is retained in glaciers and is hard to reach.

We adhere to water conservation principles and equip our power plants with technologies which help us to reduce environmental impact.  For instance, at Sredneuralsksaya GRES we are constructing waste water treatment plant which will help to reduce balance of plant water intake from Iset water reservoir due to reuse of water in technological processes. The system was commissioned in 2019 and industrial waste water and rain water discharge into the Iset water reservoir has been completely stopped. All six waste water discharge points of Sredneuralskaya GRES have been closed and sealed. But it is just one part of the project and very soon we will update you with the news on its second phase which will improve quality of demineralized boiler make-up water at Sredneuralskaya GRES, while clarified water will return to the power plant production cycle.

And there is more! In 2019, we continued to renovate the water duct which supplies water from Volchikhino water reservoir to Sredneuralsksaya GRES, where it becomes makeup water for the power plant and district heating water for Ekaterinburg, Verhnyaya Pushma, Berezovsky and the entire town of Sredneuralsk. Within the period from 2011 to 2018 we have completed reconstruction of 2730 m of the water duct. The works were thanchless, a fiberglass pipe was installed inside the existing steel pipe.

It allowed to increase reliability of heat and potable water supply in the Sverdlovsk region.

At the same time, Nevinnomysskaya GRES Unit No.9 launched pilot projects aimed to reuse condenser discharge water for cooling of auxiliary mechanisms and for unit operation in conditions of optimum vacuum. A large-scale program on technical and potable water conservation was launched in order to improve operational culture.

We can’t imagine a day without water: we use it both for industry and households. Our power plants have been working on water conservation and minimization of losses for several year. In 2018, the Company launched water consumption and water discharge optimization project which envisages creation of cross-functional working groups at the power plants.

The project targets better health and safety culture, lower environmental impact due to reduced balance of plant fresh water consumption and, therefore, smaller volume of polluted waste water.

Potential savings allowed by the water consumption optimization measures are currently under evaluation.  But even today we can declare that projects deliver their first optimistic results. The technical solutions are proposed to be introduced at Nevinnomysskaya GRES Unit 6-10 and Konakovskaya GRES Units.

Enel Russia has already joined the global movement for the UN Sustainable Development Goals. Thanks to the water conservation program we are gradually moving towards the UN Sustainable Development Goal No. 6 (SDG No. 6) “Ensure availability and sustainable management of water and sanitation for all”.
