Kathmandu Metropolitan City has started installing 'dry risers' in narrow roads and alleys where fire engines cannot go in case of fire. The disaster management department of the metropolis has rapidly advanced this work, while the wards are also installing this system from the budget of the wards where it is not included in the central plan.
City Police Superintendent Bishnu Prasad Joshi informed that ``Dry risers'' have been installed in 6, 7, 9, 13, 17, 18, 21, 25 and 27 of Kampa, while the installation of this technology is being done in other wards as per requirement. According to him, some of the inner streets of Kampa are inaccessible for fire brigade and ambulance. This technology has been installed because it is difficult to control when there is a fire or other disaster in the narrow street.
Joshi said, 'It is believed that it will help in fire control', according to him, dry riser pipes have been dug and taken to the inner streets, while 'outlets' have been placed to connect the water pipes of the fire brigade. Outlets are placed at a distance of about 30 meters. Dry riser is a dry pipe line that can be used to extinguish fire in narrow streets and alleys where fire cannot go. If water is flowing regularly in the pipe, it is called 'wet riser'.
On both sides of the dry riser, an 'inlet valve' is placed at the place where the fire engine reaches. After this, outlets are placed at a distance of 45 meters to 75 meters. After keeping the water of the fire engine in the 'inlet', depending on the need, whatever 'outlet' is opened in the middle of the 'pipeline', water is received. It is used to control fire.
When water is sent from the fire engine at a pressure of eight bar, the water reaches a pressure that can extinguish the fire in a seven-story high building.
How does a dry riser work ?
The structure that sends the water from the fire engine through the pipe to the inner lane is called 'dry riser'. In common parlance it is understood as 'pipeline'. But this pipe is thicker than other pipes because the water of Dakamal comes with a lot of force. The outlets are also strong.
In this way, the mouth of the fire engine pipe (hose) is connected to the pipe kept in readiness. Only then 'fire fighting' is done. Installing this type of pipeline is not very expensive, so it is effective in urban areas.
