Water tanks for fire fighting system

The water storage tanks are used to feed the fire pumps and thus ensure a correct flow of water: amount, quality y presión necessary.

They are generally sized to meet the total water demand for sprinklers and hose discharge during the duration of a fire, which must comply with the certifications established by local and/or international standards.

The importance of having a water storage tank is so that in the event of an accident or outbreak of fire, there is enough water to be able to attack the fire in the early stages.

Elements of a fire water tank

The elements and types of tank used in the fire fighting system are commonly made of steel, bolted and/or welded with a geotextile membrane.

These tanks have a galvanized finish or epoxy coatings to improve their quality.

The Tanks must come with their equipment, for their good functionality:

  • Water level indicator
  • Discharge pipe (Control Valve and Check Valve)
  • Filling Pipe
  • Man entrance for cleaning
  • Drain Pipe
  • Anti-Swirl Plate (Suction Tanks)

The "Gravity Tanks They are placed above the fire protection systems which serves to take advantage of the lifting load and increase the pressure available in the fire protection system.

General Installation Tips

Firstly, it is important to know what type of terrain we will have our tank on, as well as define what type of foundation will be required:

  • Ring
  • Bimini

The above is essential to have good civil engineering in both design and execution; since otherwise we could have serious problems in the future:

  • tilted tanks
  • Fugue
  • Settlement

For bolt-on tanks, the floor is installed first, and then each level of the tank from bottom to top.

For membrane tanks, it is done with hydraulic jacks; and this is done starting with the highest ring at the first level of the ring; With this modality you avoid having to work at heights, which are risky.

Applicable norms or standards
NFPA Standard 12
NFPA Standard 22
Important: Define Seismic Zone: Geographical place which is defined by having tectonic activity (earthquakes) and are defined by areas in Manual FM 2-0.; since, for the Storage Tanks, these will have Seismic Anchors around them, to avoid telluric movements.
