FIELD: water supply.
SUBSTANCE: invention relates to water supply. Reservoir (1) comprises wall including bottom, sidewall (3) and cover (4). Device for aerodynamic interaction of inner cavity (6) of reservoir with surrounding atmosphere is installed in wall of reservoir (1). Facility is made in the form of box (5) mounted either into cover (4) of the reservoir, or into the side wall of the reservoir above the maximum possible level of water in reservoir (1). Box (5) is filled with filtering material (8) and is provided with working surfaces (9 and 10) containing holes designed to provide bidirectional filtration of air participating in said aerodynamic interaction.
EFFECT: excluding penetration into the drinking water of the reservoir from ambient atmosphere pollutants.
