Fire Water Storage DIN 14230
One of the most important measures of preventive fire protection is the provision of sufficient quantities of extinguishing agents. Water is the most suitable extinguishing agent for the vast majority of fires. If the supply from the drinking water network is possible, this solution is implemented.
In many cases, however, an independent supply of extinguishing water is necessary. Open water bodies, fire water wells, fire water ponds and underground fire water tanks can provide a solution here. The calculation of the extinguishing water demand when drawing from tanks depends on the type of development. For new developments, a decentralized fire water tank allows for reduced cross-sections of potable water supply. In this context, an underground fire water tank is an artificially constructed, covered fire water storage area.
We offer DIN 14230-compliant systems for firefighting water systems. Depending on the required size, space requirements, delivery time and desired design, our fiberglass-reinforced plastic tanks or the DRAINMAX tunnel system with waterproof foil jacket are available.
Our fire suppression systems have a suction connection according to DIN 14244. The water intake point must be located outside the debris shadow of buildings. The number of suction pipes depends on the total volume of the storage tank. For small volumes (75 m³ - 150 m³), at least one suction pipe is required; for medium volumes (over 150 m³ - 300 m³), at least two suction pipes are required; and for large volumes (over 300 m³), at least three suction pipes are required.
Glass fiber reinforced fire water tank
In recent years, fiberglass-reinforced plastic storage tanks GRP tanks, have proven particularly useful for fire water storage. Today, these are produced on a project-specific basis and at low cost up to 100 m³ capacity from a single piece on an automated production line. A heavy load capacity of up to 60 t (SLW60) and a low space requirement during installation are possible in this way.
DRAINMAX tunnel fire water system
Another low cost variant for fire water storage can be realized with the DRAINMAX tunnel. By laying the system in a foil jacket, almost any system size can be realized with a very flat structure. This saves costs for civil engineering. This special foil is an absolutely watertight, high-strength, elastic EPDM foil without any connecting seams made of one piece.
Stainless steel piping according to DIN 14244 for the fire extinguishing water system
Each fire water tank must be equipped with at least one vent pipe with a diameter of at least DN100. The vent pipe must be protected against contamination. It may be installed in the manhole cover or in the immediate vicinity of the suction pipe. For multiple tanks, at least one vent pipe must be installed for each individual tank.
Fire water tanks must be equipped with a fire water suction connection according to DIN 14244. The extraction point must be located outside the debris shadow of buildings. The number of suction pipes depends on the size of the tank. Small tanks (75 m³ - 150 m³) require at least one suction pipe, medium tanks (over 150 m³ - 300 m³) require at least two suction pipes, and large tanks (over 300 m³) require at least three suction pipes. The suction pipes must have an inner diameter of 125 mm and must not exceed a length of 10 m.
Remote monitoring and multiple use of fire water tanks
INTEWA CONNECT uses the symbiosis of the control unit, the buried system and an I-CONNECT web application which is clearly displayed via an interface on a PC, tablet or smartphone or offline via a USB connection. With the innovative I-CONNECT technology, extinguishing water storage tanks can now be monitored remotely from anywhere in the world and can even be used for multiple purposes.
