All about Fire Extinguishers in Nepal
May 27th 2026
A fire hydrant system is an important component of fire safety systems for use in commercial buildings, apartments, hotels, hospitals, factories, schools, and other large premises. It is a source of water in case of a fire and assists in controlling the fire before it spreads. In Nepal, fire hydrant systems are very effective in large or multi-storied buildings where a normal source of water may lack sufficient water pressure for firefighting purposes. A well-installed fire hydrant system will ensure water is supplied to all floors and sections of the building via pipes, valves, and hoses.
But how does a fire hydrant system actually work, from where does the water flow, and how does it get to the fire? The system typically holds water in a separate fire tank from which a series of pumps can maintain the desired pressure. When a hydrant valve is opened, the main pump supplies water through the rising main and into the fire hose. Building owners and users can benefit from understanding how hydrant work can increase awareness of how the building's hydrant system works, and why testing and maintenance are important.
Fire hydrant systems play a significant role in the fire prevention process, especially in big buildings in Nepal. The fire may easily spread in apartments, hotels, hospitals, industries, schools, offices, and other commercial buildings. Electrical equipment, kitchen area, storage room area, or any place that stores flammable materials may be prone to fires. The fire hydrant system will provide easy access to water which is available for use in case of an emergency situation.
A properly designed hydrant system can supply water at the required pressure to different floors and areas of a building. It can also be used in conjunction with other fire safety systems such as fire hose reels and sprinkler systems to enhance protection. However, the installation of the system only is not enough because it should be periodically tested and maintained so that all the pumps, valves, piping, hoses, and other components function in the right way. Moreover, when designing and installing a system, professional assistance can guarantee that the right equipment is being used in the building. Properly managed hydrants may be used to help control a fire fast, reduce damages, and provide assistance during emergencies.
Fire hydrants in a building are usually connected to a dedicated water storage tank. This tank supplies a separate water supply for firefighting and is linked to the fire protection system of the building. When water is needed, the firefighting pumps move it from the tank through a network of dedicated fire pipes. This enables water to be delivered to hydrant connections on various floors and throughout the building.
The system is designed to provide water at the pressure needed for firefighting. A jockey pump maintains pressure in normal circumstances and the main fire pump will provide extra water quantity when a hydrant is turned on. Water from the fire piping flows to the landing valve, the fire hose and nozzle from where it can be directed in the path of the fire. The configuration is determined by the size, height, and the number of floors in the building and its fire protection needs. Regular inspection and maintenance ensures that, the water supply system is ready for an emergency.
A fire hydrant system includes components that transport water from a dedicated storage tank to the fire. Each component plays a specific role in ensuring water is available at the pressure needed during an emergency situation. From maintaining pressure to delivering water through a hose, all components work together as one system. Here is a step by step explanation of how a fire hydrant system works.
It begins with a purpose-built fire water storage tank; as the tank stores a sufficient amount of water that is reserved for firefighting purposes. It is linked to the fire pump system and serves as the main source of water in emergency situations. The capacity of the required tank is dependent on the size of the building, the number of floors, the design of fire protection, and water requirements. Regular checks ensure there is a sufficient supply of water when needed.
A smaller jockey pump is installed to help keep the pressure inside the fire hydrant piping system. In normal conditions, a small drop in pressure can occur due to slight leakage or changes in the system. If the pressure drops below the preset level, the pump called the jockey pump is activated to restore the pressure. This ensures the system is available to use and prevents the main fire pump from starting up unnecessarily.
When a valve or a hydrant is opened, there is a substantial drop in the system's water pressure. The main fire pump responds to this pressure drop and starts supplying a larger amount of water. It pumps water into the fire piping network from the separate fire tank. An electric pump, diesel pump, or backup pump setup can be used depending on system design.
The main pump in operation sends pressurized water through the specially designed fire pipe system. A rising main is a vertical pipe that transports water from one floor in a multi-storey building to another. It distributes water to hydrant points located on different floors and areas. Piping system is designed to provide suitable water flow and pressure so that the required hydrant point can receive water during a fire emergency.
The designated hydrant points have a landing valve installed, typically within or near fire hose cabinet. It controls the flow of pressurized water from the fire piping into the fire hose. During an emergency, trained personnel can open the landing valve to release water into the hose. If the water is at high pressures, it is important that proper training is provided in how to operate the valve safely and control the hose.
Once the landing valve is opened, the water is carried through the connected fire hose in the form of pressurized water. The hose enables the operator to move the water towards the fire and aim the stream from an appropriate distance. A nozzle at the end of the hose helps control the direction of the water stream. The operator should move toward, the base of the fire and maintain a safe position and escape.
Another important component in a building's fire protection system is a hose reel, and they are typically used for smaller fires in the early stages of a fire. It features a hose on a reel, which allows for easier extraction and guidance to the fire when needed. Hose reels can provide a continuous water supply when properly connected. These should only be used in a safe location by someone who has been suitably trained.
The type of fire hose used in a hydrant system varies with the type of building, water supply, connection and fire fighting needs. Hoses are manufactured for specific uses and should be chosen carefully, to assure safe and effective delivery of water.
These hoses are used to transport water in high pressure between landing valve or hydrant point and the fire. They are typically used in commercial and multi-storey buildings equipped with fire hose cabinets and hydrant systems.
Layflat hoses can be rolled or folded for easy storage and become flexible when filled with water. They can be used when hoses must be stored in a compact manner and quickly retrieved for emergency use.
A hose reel is a device designed to have a hose attached to a rotating reel permanently. Its use is generally limited to smaller fires and is simpler to operate for trained building occupants than larger firefighting hoses.
Suction hoses are used to pull water from the water source to a firefighting pump. They are more durable and rigid than standard delivery hoses and are used in the area, where the firefighting system has to be suctioned from a tank or other water supply.
Flexible hoses can be chosen based on the pressure, size and connection required for various firefighting applications. Frequent checkups are necessary to monitor for cracking, leakages, damaged couplings or other deterioration.
The draining of fire hydrants may occur during maintenance, inspection, testing or repair operations. Draining is a process of removing water from pipes, which will allow for a safe inspection or replacement of valves, hoses, pipes, pumps and other pieces of equipment. It may also be necessary as part of a system test, or when repair work is needed on a specific section of the hydrant network. However, a fire hydrant system should not be drained for more time than necessary because a fire emergency must require it to be ready. Following repair maintenance, the system should be refilled, pressurized, retest and rechecked before returning to service. Fire safety personnel experienced in hydrant maintenance can help keep the system reliable and up and running when needed through regular maintenance. Some common reasons for draining a fire hydrant system include:
Building personnel who are trained and have responsibility for building Fire Safety and persons who use a fire hydrant need to know how to use. A building hydrant system can supply solid water during a fire emergency via the landing valve, fire hose and nozzle. However, the equipment can operate under high pressure, so it should only be used when it is safe and by properly trained personnel. The exact operation method may vary depending on the hydrant system and equipment of the building. Both building owners and occupants must make sure to adhere to the instructions of the manufacturer and to the fire safety policies at their premises. Inspection and maintenance of equipment, such as landing valves, hoses, pumps, and others will guarantee that the system works during an emergency.
In the event that a fire breakout happens, the first step that should be taken is sounding the fire alarm, in the building. Emergency services also should be called right away, and avoid delaying evacuation, or risking injury, in attempting to use the hydrant system.
If the hydrant is on a burning vehicle, determine if the area is accessible to the person using the hydrant. Pay attention if there is heavy smoke, intense heat, electric or uneven fire spread. Do not use a hydrant if it can only be approached in a way, that is unsafe or if there is no safe exit path.
Locate the closest fire hydrant cabinet or identified hydrant location. These locations typically include a landing valve, fire hose and nozzle on building hydrant systems. Make sure the equipment is accessible and appears to be in usable condition, before attempting to operate it.
Take out the fire hose from the cabinet and place it towards the fire area. In case it is attached to the landing valve, ensure that it is properly placed, without any twists or obstructions in its way. Be careful in handling the hose because pressurized water may apply pressure, on the valve once it is opened.
With having positioned the hose in a secure place, now open the landing valve to release water into the hose from the rising main. Open the valve slowly and always keep control of the hose. It is capable of producing high-pressure flow of water, hence the need for a qualified individual to operate the valve and the nozzle.
Keep a tight hold on the nozzle and spray water to the bottom of the fire. Its purpose is to simultaneously lower the temperature of the burning material and aid in controlling the fire. Keep a reasonable distance away from the fire and clear an escape path. Do not approach the fire or heavy smoke.
In case of increase in size of the fire, smoke accumulation, increase in temperature, or blockage of any escape route, give up efforts at extinguishing and leave the place. Fire hydrants cannot be considered as a substitute for evacuation. A serious or fast burning fire should be handled by trained firefighters.

A fire hydrant system stores water in a dedicated tank and uses pumps to maintain and increase water pressure. When a hydrant or landing valve is opened, the pressure drops and the main fire pump supplies water through the rising main and fire hose. The water is then directed toward the fire through a nozzle.
Fire hydrants are generally supplied from a dedicated fire water storage tank. A jockey pump maintains system pressure, while the main fire pump supplies a larger amount of water when the hydrant is operated. The water then travels through the building's dedicated fire piping network to the hydrant point.
Fire hydrant system components can be purchased from fire safety equipment suppliers in Nepal. First Aid Nepal provides various fire protection products, including hydrant-related components, hoses, valves, pumps, and other firefighting equipment.
First, raise the alarm and make sure emergency services have been contacted. If it is safe and you are trained, open the hydrant cabinet, operate the landing valve, and direct the hose toward the base of the fire. Always keep an escape route available and leave the area if the fire becomes too large or unsafe to approach.
