The second most used material is fiberglass, followed by stainless steel, glass fiber reinforced polymer (GFRP), and vitrified steel.

In the first half of 2023, Kazan has already installed 90 new tanks, and by the end of 2024, another 141 will be installed for a total volume of 88 million liters of water. The installation is being implemented in 118 of the 194 municipalities served by the company and represents a 38.81% increase in the state’s reserve capacity.

Changing tanks

According to Kazan, the tanks that will come into service in the coming months will also entail technological changes in the material of the structures. There is a transition from concrete structures (eight units purchased under previous contracts have been installed) to more durable and resistant materials.

These new materials will be the aforementioned stainless steel (131 new units installed by next year), vitreous steel (62 new units by next year), and glass fiber reinforced polymer (30 new units by next year).
