Modular fire water tank: a hygienic, rust-free fire water reserve built from galvanized, GRP composite or stainless steel panels in project-specific dimensions.

In short: A modular fire water tank is a water reserve built by joining galvanized, GRP composite, specially coated or stainless steel panels in 1075 mm modules, in a project-specific size and shape. Its cornerless structure prevents sediment and bacteria build-up. Özaydın Yangın sizes the volume by hydraulic calculation and designs it with the pump room.

Contents

Modular fire water tanks are reservoirs that supply water to fire suppression systems, built by joining galvanized, GRP composite, specially coated or stainless steel panels on a plastic base. Because panel dimensions are produced in multiples of 1075 mm, a tank can be enlarged to the volume required by adding modules, and it is easier to transport to site and install than a single-piece reinforced concrete or sheet-steel tank. Together with the pump room, this structure forms the water source for sprinkler, fire hydrant and fire hose cabinet lines, and it is designed in integration with the fire pump set and fire water tank sections on the Mechanical Systems page.

Modular tanks do not have to be squeezed into a single rectangular volume; they can be designed in L, H, U or triangular forms to fit project-specific and irregular spaces such as under stairs, under garage ramps, between columns and under beams. The capacity range extends from 1,250 liters (1075×1075×1075 mm) to 200,000 liters (9675×9675×2150 mm), and intermediate capacities are achieved by adding or removing modules; for sites with limited space, 5,000, 7,500 and 12,500 liter "Eco" variants are offered with a lower profile. The same product family can therefore meet the water reserve needs of both large facilities and existing buildings with tight space.

The volume required for the fire reserve is determined by hydraulic calculation based on the flow and duration requirements of TS EN 12845 and BYKHY (Turkish Fire Protection Regulation); the modular tank provides this calculated volume in a form and capacity that fits the site's existing layout. In conventional black sheet-steel tanks the paint usually flakes off quickly and rusting begins, concrete tanks without ceramic lining can harbor bacteria, and plastic tanks can grow algae in sunlight. The modular panel construction, with no sharp corners, prevents sediment and bacteria buildup; this hygiene advantage is also valuable in potable and utility water tanks beyond fire reserves, and the tank is operated within the same maintenance and inspection cycle as the fire pump.

4 solutions, each for a specific need

Engineered system options selected by occupancy, hazard class and building architecture, backed by design calculations.

Galvanized Modular Tank

An economical, widely used modular fire water tank made of galvanized-coated panels.

The galvanized modular tank is built by joining zinc-coated steel panels on a plastic base. Thanks to the panel construction, the tank can be enlarged or reduced to the space allocated in the project, which is especially useful when fire reserve needs are added later to existing facilities.

Galvanized coating resists corrosion longer than conventional painted sheet-steel tanks; however, in environments with constant moisture or chemical vapors, GRP composite or stainless steel options can be considered.

GRP / Stainless Steel Tank

GRP composite or stainless steel panel tank options that offer the highest corrosion resistance.

GRP composite panels are made of glass fiber-reinforced polyester and carry no rust risk; specially coated or stainless steel panel options serve the same purpose and are preferred at sites with high humidity, salty air or chemical exposure.

These materials offer a structure that needs no paint maintenance over the long term and leaves less room for bacteria or sediment to build up on the inner surface; they are the choice especially in facilities where water quality matters.

Project-Specific Form Tank

Tanks designed in L, H, U or triangular forms to fit under stairs, under ramps and between columns.

Not every facility has room set aside for a standard rectangular tank. The modular panel system makes it possible to design L, H, U or triangular tanks for constrained spaces such as under stairs and garage ramps, between columns and under beams.

Form selection is made according to the void measured in the site survey and the total volume required; having module dimensions as multiples of 1075 mm ensures volume is calculated correctly in different geometries as well.

Modular Fire Water Tanks

Capacity and Layout

A modular capacity range from 1,250 liters to 200,000 liters, designed together with the pump room.

Modular water tanks are sized between 1,250 liters (1075×1075×1075 mm) and 200,000 liters (9675×9675×2150 mm) in multiples of 1075 mm modules. For sites with limited space, lower-profile "Eco" variants of 5,000, 7,500 and 12,500 liters are available.

The required tank volume is determined by hydraulic calculation based on the flow of the system to be protected and the duration requirements of TS EN 12845/BYKHY; the tank is designed with the fire pump and pump room as a single water supply system.

Frequently Asked Questions

Modular Fire Water Tanks: frequently asked questions

What determines the cost of a modular water tank?

Cost depends on the calculated total volume, the panel material (galvanized, GRP composite, specially coated or stainless steel), whether a standard rectangular or a project-specific L-H-U/triangular form is needed, and site conditions at the installation location. Larger or custom-shaped tanks can cost more than standard ones in module count and labor.

How many tons should a fire water tank hold?

The required tank volume is not given as a fixed figure; it is set by hydraulic calculation from the building's occupancy class, the flow of the protected system, and the duration requirements in TS EN 12845 or BYKHY (Turkish Fire Protection Regulation). Because the modular structure scales from 1,250 liters to 200,000 liters in 1075 mm modules, any calculated volume can be met to suit the site.

What is the difference between a modular tank and a conventional sheet-steel tank?

In conventional black sheet-steel tanks, paint soon flakes and corrosion begins; concrete tanks can become a bacteria habitat unless ceramic-lined, and plastic tanks can grow algae under sunlight. Modular tanks have no sharp corners, so less sediment and bacteria accumulate, and galvanized, GRP composite or stainless steel options give a longer-lasting solution against corrosion.

When is a project-specific tank shape needed?

When space cannot be set aside for a standard rectangular tank, such as under stairs, under a garage ramp, between columns or under beams, an L, H, U or triangular modular tank is designed. The shape is determined at the design stage from the void measured in the site survey and the calculated total volume.

What materials are modular water tanks made of?

Panels are produced from galvanized, GRP composite, specially coated or stainless steel and mounted on a plastic base. Material is chosen according to the environment's humidity, chemical vapors or salty air, budget and expected service life; GRP and stainless steel give the highest corrosion resistance.
