Fire Sprinkler Water Storage Tank Installation
Hospitals, hotels, apartment buildings and office parks require fire protection tanks that meet the NFPA (National Fire Protection Association) requirement. When locating these building in rural areas the high volume of water required for firefighting is not readily available. Drilled wells do not have sufficient water flow because the aquafer needs to recharge to sustain the flow rate. To solve this problem, a storage tank is used to continuously collect and store enough water to meet the requirements of the fire sprinklers and mobile fire suppression apparatus.
Automatic Sprinkler Systems require a constant water pressure in the supply lines to keep a building protected. These sprinklers are meant to control a fire and not completely extinguish it. Needed Fire Flow (NFF) is defined as the rate of flow considered necessary to control a major fire in a specific building for certain duration. An example of NFF for a 28,955 square foot building with an extra high hazard group 2 classification requires 1,000 gallons per minute be used for duration of one hour which is the recommended NFPA hose stream allowance. That equates to 60,000-gallons of water storage. This capacity and water flow rate is best achieved using underground storage tanks.
Advantages of Installing an Underground Fiberglass Tank
- Underground water storage tanks won’t freeze (average winter temperatures in New England is 50 degrees) and are less likely to grow bacteria and algae
- Fiberglass tanks do not rust or corrode
- Underground tanks with lockable hatches are safe from vandalism
- Fiberglass tanks do not develop hairline cracks like the ones that form in concrete tanks and are not subject to corrosion as steel reinforcement does in concrete
- Multicompartment underground storage tanks can store both drinking water and fire protection water in separate chambers.
- Multiple tanks can be manifolded together to build large storage systems
- Fiberglass tanks meet the basic National Fire Protection Association 1142 and NFPA 22 structural design, storage capacity, and fire flow requirements.
