Fire extinguishing water supply for the Ovčiarsko and Žilina tunnels
In order to ensure a supply of fire extinguishing water to both tunnels, fire extinguishing water systems are being installed according to national regulations. Both fire extinguishing water systems include fire extinguishing water tanks, pressure boosting units and controllers, as well as fire extinguishing water pipelines with portal and tunnel hydrants. The fire extinguishing water pipeline in the Žilina tunnel is designed as a DN 125 ductile cast iron “dry pipeline” with thermal insulation. The fire extinguishing water pipeline in the Ovčiarsko tunnel is designed as a DN 150 ductile cast iron “wet pipeline” with trace heating and thermal insulation.
