The water tank is a two-chamber tank that is used exclusively for the storage of water. The first chamber is used for storage of water and the other one as an anteroom for the supervision and maintenance of the tank. The first chamber is equipped with pipe connections for water supply and drain as well as the fuel tank drain, overflow, vent and inlet openings.

Water drain can be gravitational or executed with electric pumps located in the anteroom. Access to anteroom is possible through vertical shaft or through horizontally placed pipe.


Water reservoir is usually container buried in the ground with enabled access to the anteroom through a vertical shaft or horizontal pipe. Non-transit shaft is equipped with a vent hole and safety lock.

Access through the water pipes is used when the water reservoir is built on a slope. The entrance to the pipe is secured with steel doors.
