Fire Hydrant and Sprinkler Drawing


In Commercial or Residential building, a fire hydrant system is a safety measure or emergency equipment required in some buildings that comprises a series of components that when assembled together provide a source of water to assist fire authorities in a fire. In some circumstances, water from a reticulated fire hydrant system can also be shared with other safety measures such as automatic fire sprinkler systems or fire hose reels.

We must follow NFPA & BNBC for made a design and reviewed from Accord, Alliance &ILO  for every projects is consideration below items :
Fire hydrants systems are designed and installed in accordance with NFPA & BNBC comprise the following primary components:

  • Hydraulic  simulation& Calculation
  • Water Supply & Storage
  • Pipe work & Valves
  • Fire Brigade Connection
  • Pump set
  • Hydrant, Hydrant Valve or Landing Valve & Coupling
  • Fire Hose
When designing a fire hydrant system specific performance objectives must be satisfied. These performance objectives require a hydraulic simulation analysis to demonstrate there is sufficient water pressure and flow at the most hydraulically disadvantaged hydrant. The pressure and flow requirements vary according to the building classification, floor area and sprinkler protection.
