USE

Horizontal, underground, single-chamber, water storage reservoirs are used for drinking water storage, which allows to equalize periodical water deficits, caused most often by too small yield of well at the water intake in relation to the requirements. Horizontal, underground, water storage reservoirs are at the same time a kind of additional protection of water source used for fire-fighting purposes.

STORAGE RESERVOIR CONSTRUCTION

Undreground, horizontal, single-chamber, water storage reservoirs are made of low-carbon, certified steel. The reservoir's jacket is produced in the shape of horizontal roll, which is closed from both sides with flat, ribbed heads or heads of small convexity (depends on reservoir's diameter). There is a revisory manhole DN 700 in the jacket. It's construction is adapted for burring. The revisory manhole is closed with an external leakproof lid. Inside the manhole there is an additional lid, which protects it against the pollution getting inside when the external lid is unsealed. In the upper part of the reservoir there are 2 breathing connections with air-filtration system. The amount and size of the connectors is shown in the picture. Manufacturer allows changing the amount, size and placing of the connectors on the basis of Buyer's individual guidelines.

Internal reservoir's surfaces are protected against the corrosion with "BRANTHO-KORRUX" paint with PZH certification for contact with drinking water. Externally the reservoir is protected with an appropriate bituminous lacquer layer strengthened with a cloth.

TRANSPORT, FOUNDATION & ASSEMBLY OF WATER STORAGE RESERVOIR

Reservoirs are delivered at the destination place as complete ones. Their assembly means only putting them on prepared foundation and connecting the sockets to the system.

Reservoir foundation should be done acc. to a separate building design, which takes into account the place and conditions of its installing. But it should be placed on the concrete base enclosing the whole reservoir length and one-third of its perimeter or in earth bed made on stabilized soil enclosing one-second of its perimeter.

CONSTRUCTIONS OUT OF THE SERIES OF TYPES

Water storage reservoirs of volumes not defined in the series of types are produced on the basis of Buyer's individual guidelines. In case of preparing an order we need the following information:

1. reservoir nominal capacity,
2. reservoir diameter or length,
3. connecting sockets' size, amount and location,
4. revisory manholes' size and amount.
